nell University. These bear the MS name Cyrtolobus concinnus 

 given them by Dr. Uhler and adopted by Dr. Goding when 

 describing the species. I prefer to consider this as the type of 

 Dr. Goding 's genus Evashmeadca as it is the only one answer- 

 ing to his description in having three longitudinal nervures at 

 the base of the elytra. His other two species are the two sexes 

 of a species of Vandusea. This genus is not more distinct from 

 Cyrtolobus than is Atymna and Xantholobus. They all run 

 together and I prefer to place them at subgenera for the 

 present. 



Subgenus Xantholobus n. subg. 



In general aspect intermediate between Carynota and Cyr- 

 tolobus. Form oval, pronotum swollen posteriorly, viewed 

 from the side regularly arcuated from behind the humeral 

 angles to the tip; without a posterior sinus in the more typical 

 species; viewed from above much inflated and strongly com- 

 pressed at the middle forming a large cyst or inflation before 

 and a smaller one behind, the latter more or less confused with 

 the swollen posterior disk of the pronotum. Elytra with three 

 contiguous nervures at base and typical Cyrtolobus venation. 

 Otherwise as in Cyrtolobus. 



Surface hirsute; pronotum typical of the subgenus with the 

 posterior inflation of the pronotum pronounced ; anterior 

 sinus placed well back, almost behind the post humeral 

 sinus, 3, inflatus V. D. 



Surface smooth or nearly so ; posterior inflation of the pronotum 

 less pronounced, i. 



i. Size large, 7-8 mm. ; Crest conspicuously inflated in two 

 cysts, with a deep median compression; posterior sinus 

 obvious, 2. 



-. Size small, 4 mm. ; anterior sinus obscure, just behind the 

 humeral angles; crest regularly arcuated, but little infla- 

 ted before, with a slight compression, posteriorly lost in 

 the moderately swollen pronotal apex, 



4, nitidus V. D. 



2. Crest distinctly elevated with an obvious sinus before and 

 behind; color ferruginous or rufous brown with the char-
