The syuouymy of Lacliiioinma with Paradidyma is given with a query 

 by Brauer and Bergeiistauim.' lu the Trans. Amer. Ent. Soc. for 

 1895, page 77, Mr. Townsend suggests that the supposed type species 

 of his two genera, Atrophopoda and Lachnomma, are but the opposite 

 / sexes of one and the same species, and the specimens in the National 

 h£u^ Museum fully establish the accuracy of this supposition. Our single 

 species is black, the palpi and apex of proboscis yellowish; three 

 ^ "^ , postsutural and three sternopleural macroch.Eta? ; length, G to 9 mm.
