AMERICAN BIPTERA. 25 



This species agrees witli Wiedemann's description very well, but the 

 synonomy rests upon more direct evidence. Specimens in Prof. v. d. 

 Wulp's collection without locality were compared by Prof. Mik with the 

 typical specimens in the A^ienna Museum, and specimens that I com- 

 municated to V. d. Wulp, he writes me are I). Wintlicml Wied. I have 

 specimens from Indiana and Kansas that sliow no difference from a num- 

 ber of individuals that I captured in an open field in June near New 

 Haven. • 



38. Deroinyia discolor. 



Diogmites discolor Loew, Centiir. vii. 37. — Penna. 

 A single, somewhat rubbed specimen from Pennsylvania (S. Auxer) 

 agrees with Loew's description. 



3H. Deroniyia nmbrina. 



Diogmites mnhriva.s Loew, Ceiitur. vii, 43. 



Dafsypogon baxalis Walker, Di])t. Saund. 95. 



Hevevyiius Walker, List, etc., ii, 339. 



This species is recorded from N. Y., Mass., and 111. by Ostcn Sacken. 

 I have taken numerous specimens in Connecticut and have it from Ver- 

 mont. The abdomen is nearly like that of Saropognn. 



40. Deroinyia angustipennis. 



Diogmites avgustipennis Loew, Centur. vii, 41. Kansas, Mexico. 

 A single specimen from Kansas has the legs lighter and the dorsal 

 thoracic stripes darker than Loew describes, yet it is evidently this species. 



41. Deroniyia teriiata. 



Diogniiles ternaliis Loew. Centur. vii. 38. — Cuba. Florida. 

 A single specimen from Oeorgia is probably this, but from the varia- 

 bility of the species, I am in doubt. 



Species incerfde xedis.

P--H'- 

 If my determination is correct this is not a Ldpnnis nor does it even 



belong in this division of the Ddsi/pogoidnae. My specimen agrees 



throughout with Bigot's description, except that the femora are black ; 



the ''eperon (i pen pren droit et noir,'' in my specimen is only a stout 



black spine '. I cannot at present place this species. The head and 



wings are like CdUiiiicim. but the abdomen is shorter, of equal width 



and cylindrical, and very different in general appearance.
