LECTOTYPES OF NORTH AMERICAN CADDIS FLIES IN THE MUSEUM OF COMPARATIVE ZOOLOGY1
Illinois State Natural History ' Survey, Urbana, Illinois
Few species of caddis flies described by Hagen and Banks have had lectotypes designated for them. In a few cases the type series of one species contains representatives of more than one species, a condition which has led to confusion of names due to different interpretations made by different authors. The only way to obviate further repetition of this is to place on a single type basis (by lectotype designations) all those species described from a series of eotypes. This paper sets lectotypes for 229 species, all the lectotypes being in the collection of the Museum of Comparative Zoology. The method followed in selecting the single type specimens has taken into account very little work done by other au- thors, since a large number of the species represent segre- gations seldom recognized by others. Furthermore both Hagen and Banks used a labelling system which left no doubt as to which specimen they considered the real type. Hagen placed his label on only one specimen and marked it with an asterisk if it were a type or plesiotype in the sense of present usage. Other specimens in the series were simply placed in 1A grant from the travel fund of the Illinois State Natural History Survey, Urbana, Illinois, made it possible for me to visit the Museum of Comparative Zoology and make these studies. I wish to acknowl- edge my gratitude and appreciation to the Survey for this grant. Pachc 45:l-61 11938). http //psychr enlclub.me/-IS/45-001 him)

a row after the first labelled specimen; undoubtedly some specimens which are not actually types were put in these series at the same time or subsequently, either by Hagen himself or inadvertantly by others. In selecting lectotypes of Hagen's species the specimen labelled by Hagen has been taken in each case. Lectotypes have been designated for all the species from North America described by Hagen unless they have been previously set in literature, even if only rep- resented in the collection by a single individual. This is done because of the possibility of specimens appearing in other collections which might erroneously be considered as types.
There is a possibility that some specimens designated as lectoallotypes have not been correctly associated with the lectotypes, that is, do not represent the opposite sex of the same species as the lectotypes.
In a very high proportion of
the North American caddis fly species it is impossible, with our present studies, to separate the females of closely re- lated forms, so that we have to rely to an inordinate extent on collection data as a basis for association. All the specimens mentioned as "allotype" represent des- ignations made for the first time in this paper. In the Banks collection the specimens listed without de- finite collector from the eastern states were taken by Banks himself, except in a few cases.
Banks' species have his own label on the first specimen and simply a "TYPE" label on the others. The first specimen with the label has been taken as the lectotype, a procedure which Mr. Banks has requested and which seems perfectly logical.
In rare cases when these first specimens have been females and the cotype series contained males, an exception to the foregoing procedure has been instituted and a male selected as the lectotype.
No attempt has been made to analyze any of the cotype series except the lectotypes, the remainder automatically becoming paratypes. Such a study would have little signifi- cance since the paratypes will have only historic and minor taxonomic interest. Furthermore so many of the specimens have been sent in exchanges, etc., to institutions in widely

scattered countries that it has been impossible for me to gather the necessary information.
The species treated are listed within each family alpha- betically according first to genus and then to species. Many of the species have been transferred from genus to genus several times. In attempting to find some method which would be easy to follow and at the same time show the generic placement, I am using the following double entry when a change has been made. If a species is placed in a genus other than the one in which it was described, it is listed both under the genus in which it was originally de- scribed and under the genus in which I am placing it. For example, Hydropsyche sordida Hagen is now placed in the genus Cheumatopsyche. Therefore, it is listed under both Hydropsyche sordida in the h's and under Cheumatopsyche sordida. Under the former, note is made of the genus in which it is placed.
Professor Nathan Banks, Curator of insects at the Mu- seum of Comparative Zoology, and Professor F. M. Carpenter of the Division of Biology, Harvard University, have been of inestimable help during the course of this work in giving information and advice, in placing at my disposal study facil- ities and equipment, and in the many courtesies accorded me during my visit to the Museum of Comparative Zoology. Dr. C. 0. Mohr, of the Illinois State Natural History Sur- vey, has made most of the drawings for this paper, and I wish to express my gratitude for this.

At present there appear to be two valid species in this genus, the two illustrated by Betten (1934) as americana and Mystrophora sp. No good characters have been dis- covered as yet which separate the females of the two species, so that the exact status of the names americana Banks and Uvidum Hagen is problematic. It seems best at present to consider as nigrior the species treated as americana by most authors and illustrated by Betten (1934, pi. 8, figs. 4-6 and pi. 9, figs. 1-14), and to consider americana as an unidentified species.

All collections which I have seen containing specimens of both sexes are alike in having the females with minute, vestigial wings. This evidence indicates that only one species is involved in this material.

The elongate apical segment of the clasper, the V-shaped ridge on the dorsum of the tenth tergite, and the inconspic- uous apical lobes on the tenth tergite, fig. 20, distinguish the species from others in the genus. To date I have seen no specimens of this species except the type.

This species is a very close relative of annalicornis (Stephens), but may be readily separated from it on the basis of the sedeagus having two internal, large spines, and the clasper having a pedunculate sclerotized process, fig. 42. Dilutus has been incorrectly synonymized with annulicornis; it is really distinct and seems to be the only name available for the species.

The male genitalia of this type agree with those of a male from Europe determined by Hagen as annulicornis (Stephens) and answer in detail the illustrations of Mc- Lachlan. There seems no doubt but that futilis must be considered a synonym of annulicornis. The chief diagnostic characters are in the sedeagus, which has only a single, large, internal spine, and the clasper, which has a short, digitate, sclerotized process, fig. 41.

The extremely striking appearance of this species, the genotype of Halesochila Banks, is the chief character sepa- rating it from Glyphopsyche. Since it agrees so well with this latter genus in structural characters, it seems advisable to reduce Halesochila to subgeneric rank.

This widespread species has been illustrated by Betten (1934, pi. 66).
Lepidostoma Rarnbur
Many of the species here placed in Lepidostoma have been considered previously as belonging to genera separated from Lepidostoma on the basis of male characters such as vena- tion, folds in the wing, structure of antennae, etc. The male genitalia show that in many cases these definitions cut across phylogenetic lines, grouping together species which are at most distantly related and separating species which are really extremely closely related. The male genitalia show further that many of the most distinct of these groups are, at the most, an offshoot of a group of species placed in an- other genus. I feel, therefore, that many of these genera are only artificial segregates of species without any considera- tion to relationships. For this reason, I am defining the genus Lepidostoma very broadly. I agree with Mr. Banks that a thorough revision of the entire world fauna of this group will be necessary to correctly evaluate the genera. Lepidostoma bryanti (Banks), 1908a, p. 65, figs. 1, 2, 13. ( Alepomyia)
Lectotype, male.-Grand Lake, Newfoundland, July 28, 1906, 0. Bryant. No. 11709.
