THE CANADIAN ENTOMOLOGIST 265 



3, 5. In fore wings fork 1 reaches far back on cell, fork 3 hardly 

 as long as fork 2; there is no cross-vein from radial sector to radius, 

 spurs 2, 4, 4; basal joint of the antennae about as long as the vertex. 



Astoplectron connexa, n. sp. (Figs. 24, 55). 



Similar in appearance to A. boreale Prov.; body and wings 

 brown, without markings, legs paler; basal joint of antennae dark. 

 Differs from A . boreale in that the vein at upper side of fork 1 is 

 angularly bent up toward radius, and connected to radius by a 

 cross- vein, this just alike in both fore wings; in three males of A. 

 boreale there this vein is straight; besides the proportions of the 

 cells are slightly different. The male appendages are a little 

 shorter than in A. boreale. 



Expanse 18 mm. 



From Great Falls, Va., 12 June. 



SERICOSTOMATIM. 

 Olemira costalis, n. sp. (Fig. 34). 



Brown; palpi covered with long, dense, black hair; antennae 

 brown, basal joint black beneath; vertex pale in middle, vertex 

 and thorax with some yellow hair; legs yellowish; wings gray, 

 nearly uniformly coloured, fringes darker. In male the costal area 

 is swollen and reflexed over the wing, just as in 0. americana, 

 except that this reflexed part is only about one-half as wide as in 

 O. americana; venation as in that species, but in the hind wings 

 the discal cell is a little longer; genitalia similar to that of 0. 

 americana. 



Expanse 15 mm. 



From Woodworth's Lake, Fulton Co., N. Y., 19 August 

 (Alexander). 0. americana, besides the type locality, I have seen 

 it from Riverside, Mass., and Falls Church, Va. 



Micrasema falcata, n. sp. (Fig. 52). 



Brown; palpi yellowish; antennae dark at base; head and 

 thorax with gray hair; abdomen black, with white hair; legs pale, 

 with white hair. Wings brown, with scattered yellowish and black 

 hairs; venation similar to that of M. charonis; discal and median 

 cross-veins interstitial, fork 1 reaching back on discal cell further
