basal cell is much shorter than the second it is evident that the species 

 is not a TacJiydwmia. ]Mr. Coquillett separates Tachista (or TacJu/- 

 dromia as here given) from Dmpetis in his analytic key only by the 

 comparative thickness of the front femora, an elusive characteristic. 



Tachydromia nubifera Cociuillett ^ has been referred by its author - 

 to the genus Colobonevra, a genus which has very bristly legs. I am 

 unable to corroborate this from his description alone. The shortened 

 second basal cell of nubifera excludes the species from Tachydromia, 

 but the subopacjue pruinosity and colored wings are at variance with 

 the typical species of Colohoneura. 



Mr. Coquillett has assigned Drapetis favida Williston to Tachista ■^ 

 While the male is unusually slender for a typical Drapetis this species 

 lacks the constricted swollen humeri of the Tachydromia group and 

 moreover the legs are pubescent and provided with bristles and both 

 the marginal and the first basal cells are short as in Drapetis. The 

 species can with all propriety be located in Bezzi's recent subgenus 

 Ctenodropctis. It may be here noted that the description of Tachy- 

 dromia bacis Walker described from Jamaica tallies with this species. 

 As Mr. Walker's description is unusually complete, mentioning even 

 the bristles of the legs, it is reasonably certain that both species are the 

 same. I have specimens from Yucatan, Orizaba, Vera Cruz, Cuba 

 and Hayti. Mr. Coquillett reports it from Porto Rico, and Dr. 

 AVilHston's specimens came from St. Vincent. It is evidently a com- 

 mon species within its geographic range. There is an ancient and 

 brief description of Tachydromia abdominalis Wiedemann ^ from 

 China that also applies to our specimens. Ctenodrapetis ciliatocosta 

 Bezzi ^ from Australia is also quite similar, but is somewhat smaller. 

 Possibly there is but one widely distributed form. I take it that 

 abdominalis is a Ctenodrapetis rather than a Platypalpus as the abdomen 

 is desOribed as lusterless. In almost all the species of Platypalpus 

 the abdomen is shining. 



INIr. Coquillett ® thinks that Phoneutisca bimaculata Loew is a 

 synonym of macnUpennis Walker which was described from Hudson
