Lepidostoma Rambur 
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.

(Alepomyia) 
Lectotype, male. — Grand Lake, Newfoundland, July 28, 
1906, 0. Bryant. No. 11709. 
This species is a synonym of wisconsinensis Vorhies. 
Lepidostoma Carolina (Banks), 1911, p. 356, pi. 13, fig. 28. 
( Notiopsyche ) 
Lectotype , male. — Southern Pines, North Carolina, April 
28, A. H. Manee. No. 11704. 
This species belongs to the togatum group as evidenced by 
the genitalia, fig. 92. 
Lepidostoma costalis (Banks), 1914, p. 265, pi. 10, fig. 34. 
(Olemira) 
Lectotype , male. — Woodworth’s Lake, Fulton Co., New 
York, August 19, 1909. No. 11701. Allotype, female . — 
Same data. 
The allotype is evidently of the type series but did not bear 
a type label. The species has been illustrated by Betten 
(1934, pi. 64, figs. 1-5).
