270 U. S. NATIONAL IVIUSEUM BULLETIN 209 



The type of Ceropales brevicornis is lost. Fox (1892, Trans. Amer. 

 Ent. Sec, vol. 19, p. 53) reports having seen it but does not clarify its 

 specific identity. The original description fits both the present 

 species and C.fulvipes. Since the type locality (northwestern Kansas) 

 is out of the known range of C. fulmpes and well within that of the 

 present species, the name is applied here. 



Specimens (33 cf, 24 9): From Alberta (Manyberries) ; District of 

 Columbia (Washington); Illinois ("N. 111.") I Indiana (vicinity of 

 Indianapolis) ; Iowa (Ames and Sioux City) ; Kansas (Baldwin, Clay 

 County, Dickinson County, Edwards County, Riley County, and 

 Topeka) ; Louisiana (Tallulah) ; Minnesota (Fort Snelling, Luverne, 

 Norman County, Winnebago, and Yellow Medicine County) ; Mon- 

 tana; Nebraska (Bartley); New Mexico (Las Vegas); North Dakota 

 (Beach) ; Pennsylvania (Arendtsville and Newtown) ; South Dakota 

 (Cedar Pass and Phillip) ; Texas; Virginia (Falls Church) ; and "Wash- 

 ington Territory" ("Taylors, Wenass V."). 



Collection dates are from June 18 to Oct. 7, the earlier and later 

 captures being: June 18 at Ames, Iowa; June 26 at Arendtsville, Pa.; 

 June in Riley County, Kans.; Sept. 15 in Yellow Medicine County, 

 Minn.; Sept. 17 in Riley County, Kans., and at Sioux City, Iowa; 

 and Oct. 7 at Baldwin, Kans. Flower records include Asclepias pumila 

 and Solidago sp. 



This is a widely distributed but uncommon species known from 

 Louisiana, Texas, and New Mexico north to Pennsylvania and 

 Alberta. There is a single record from west of the Rocky Mountains, 

 from "Taylors, Wenass V., Washington Territory, VII-6-82."
