A Revision of the genus Calospasta LeConte. 



By F. CREIGHTON WELLMAN. 



The genus Calospasta was founded by Leconte (Class. Col 

 N. Amer., 1862, p. 273) with Epicanta elegans Lee. as type. 

 While obviously related to Tegrodera Lee. and Eupompha Lee. 

 yet the genus would appear to be a good one, bringing together 

 what is, on the whole, a natural little group of species, al- 

 though two forms hitherto included will have to be excluded 

 (vide infra}. The home of the genus seems to be the southern 

 part of North America, especially southern California, though 

 at least one species (sulcifrons Champ.) occurs in Mexico. 

 In looking through the material referred to this genus in the 

 United States National Museum and in the Philadelphia Aca- 

 demy of Natural Sciences some points of interest have come 

 to light which are herewith presented. 



My arrangement of the material which I have examined is 

 as follows this is not yet proposed as an entirely natural one, 

 but as convenient in comparing the characters of the differ- 

 ent species.

$ . General form as in the genus Tetraonyx Latr., entirely black, 

 opaque, head and thorax rather smooth, antennae moniliform, elytra 

 varying from punctate to coarsely scabrous, winged. Length 12 mm. 



9 . General form as in the genus Megetra Lee., black, opaque, head 

 slightly punctured on occiput, thorax pentagonal, broader than long, 

 sides obtusely angulate, elytra intricately rugose, apterous. Length 

 15 mm. 



There seems to be no doubt but that these forms 

 represent one species, although in the apterous 9 the 

 meso-coxae of course overlap the metasternum while in the 

 winged male they do not. They have been taken together and 

 in copula and I have before me 69 specimens (40 $ 's and 29
