A NOTE ON BERIS AA7iVLiLIFERA (BIGOT).
Boston Society of Natural History.
This seems to represent an extremely variable species. Spe- cimens with all the femora and tibiae yellow, have been referred ,
to B. morrisii Dale, a European species, which has however quite a different genitalia. I have not seen a typical morrisii from America. Numerous specimens from New England and Canada agree with Bigot's description although "Georgie" is given as the type locality. In a series of fifty-two specimens I am unable to find characters of specific value, but there seem to be three quite marked varieties, based on the general color of the legs. Not- withstanding the fact that intermediate forms exist, it seems well to consider these varieties rather than to have Bigot's des- cription the only means of determining this variable and widely distributed species.
Beris annulifera (Bigot).
Oplacantha annulifera Bigot, Ann. Soc. Ent. France, 1887, p. 21.
Legs yellow, the posterior femora with a more or less pro- minent sub-apical band of brownish black, tarsi black with the base of the metatarsi yellowish. Its distribution is as follows: Bretton Woods, N. H., June 24, Oquossoc, Me., July 2, (C. W. J.), Lake Nipigon, July 4 and Lake Abittibi, Ontario, June 23 (N. K. Bigelow), English River and Athabasca River, (Kennicot) N. Calif., (Mus. Comp. 2001.) Alaska, (Coquillett). Around the base of Mt. Washington, N. H., there are as- sociated with the typical form the two varieties described below. There is also considerable variation in the venation. The two veins extending from the tip of the discal cell may be quite widely separated, close together, or fused and petiolate. A few specimens have an angle and stub-a vestige of a fourth vein arising from the discal cell. The latter variation is best shown Psiffte 33:108-109 t 1926). http:llpsycb.cnlclub.or~33/3J- 108 html
