pronotum is less elevated with a longer and thicker tip, the 

 striae are equally distinct across the whole base of the vertex 

 and the lower surface and legs are without the black markings. 

 Here the last ventral segment of the female is long, consid- 

 erably exceeding the sixth segment of the connexivum, and the 

 hind edge is oblique and subsinuated to the broad obtuse 

 median notch. Of this species I have seen but a single speci- 

 men which was taken at New Haven, Conn., August 7th, 1905, 

 by Prof. W. E. Britton. 



14. Ceresa femorata Fairmaire, PI. 1, fig. 38. 



In this species as I identify it the pronotum is little elevat- 

 ed, the metopidium is low, its sides rise vertically for a short 

 space and then abruptly diverge to the suprahumerals which 

 form right angles with the latero-superior edges of the metopi- 

 dium ; the surface is hairy as in basalts and the face is short 

 and roughly corrugated, showing scarcely a trace of the vertical 

 striae found in many of our species. The lower surface is black 

 with the legs, hind edges of the apical ventral segments, 

 oviduct and sides of the pygofers and connexivum fulvous. 

 Ultimate ventral segment of the female short, broadly sinuately 

 emarginate almost to its base. I have one example taken in 

 Colorado. 



15. Ceresa uniformis Fairmaire. PI. 1, fig. 39. 



Stal and all subsequent writers have placed this as a syn- 

 onym of the foregoing but I have one example that corresponds 

 exactly with Fairmaire's description but is quite distinct from 

 the individual I place as femorata. Either I have wrongly 

 identified one of both of these species or Fairmaire's two species 

 are quite distinct. Judging from the material I have seen in 

 this genus I prefer to adopt the latter alternative. This insect 

 has the form of the preceding except that the metopidium is 

 more elevated with the sides rectilinear to the small tubercular 

 suprahumerals, which are minutely tipped with black. The 

 face is rough as in the last species and the apical margin of the 

 elytra is infuscated. I have a single male from Austin, Texas. 



Genus Stictocephala Stal. 



This genus may be distinguished from Ceresa by the 

 absence of suprahumeral horns. This is a purely artificial
