_lcS STUDIES IN NORTH AMERICAN MEMBR ACID.E 



rounded, scarcely carinated, meeting at about the middle; attenuated apex 

 but little surpassing the tip of the abdomen. Face impunctate or nearly 

 so, roughly sculptured, with irregular smooth areas; clypeus and lorse 

 strongly differentiated and well produced beyond the line of cheeks. Pro- 

 notum closely and strongly punctured; the dorsum almost rectilinear nearly 

 to the tip of the attenuated apex; the latter sometimes a little more strongly 

 decurved. Elytra hyaline, rarely a little suffused at apex, nervures distinct. 

 Last ventral segment of the female deeply excavated, the oblique sides of 

 the sinus a little arcuated. Color apparently concolorous green becoming 

 yellowish in drying, extreme tip of pronotum and oviduct of the female 

 blackish. Eyes banded, ocelli rufous. Length 8mm. 



Described from 12 specimens taken on the foothills about 

 Ft. Collins, and Boulder Colorado, I have not yet heard of 

 this species having been taken west of the continental divide. 

 Heretofore it has been confounded with Gilletti which how- 

 ever is a very distinct species. I have formerly determined 

 this form as the Stictocephala franciscana of Stal and it does 

 agree reasonably well with his very short description but by his 

 synoptical table of the species of Stictocephala published in 

 1869 his species must have a metopidium narrowing from its 

 base which this does not. In that table he has wrongly iden- 

 tified Say's festina. 



9. Stictocephala franciscana Stal. PI. 1, figs. 25,29. 



After a careful study of Stal's description and synoptical 

 table published in 1869 I have been led to place his name 

 franciscana on the present west- coast form although such 

 determination is at best but tentative. This species most 

 closely resembles Gilletti but the pronotum is still lower, the 

 sides of the metopidium do not diverge upward to a lateral 

 suprahumeral angle but are about vertical for a space and 

 then converge to meet behind the middle. The metopidium 

 is very low being rounded back almost from the base, the 

 lateral carinse are obtusely rounded off, the attenuated apex is 

 slender and acute, but little decurved in the female, and slight- 

 ly surpasses the abdomen ; the face is unusually large with its 

 surface closely punctured and the median line at base and an 

 area about each ocellus is depressed. Clypeus and lorae broad, 

 considerably produced but depressed beyond the line of the 

 cheeks; lateral impressed crescentic line on the sides of the 

 pronotum distinct. Last ventral segment of the female long, 

 deeply and acutely emarginate. Color brownish testaceous
