Color pale yellowish green in the dead specimen, more yellowish on 

 the head and abdomen; Middle of the pectus and a cloud on the base of the 

 venter black in the female. In the male the black covers the whole disk of 

 the venter excepting only the narrow edges of the segments. 



Described from one pair taken by Prof. H. F. Wickham in 

 California: the male at Truckee, 5800 feet altitude; the female 

 at Salton, 225 feet altitude, both in August. In the Cornell 

 University collection is a female taken at Olympia, Wash., by 

 Mr. T. Kincaid. This very distinct species may at once be 

 distinguished by the vertical metopidium, the sides of which 

 meet almost over the humeri, and the low, horizontal and 

 rectilinear dorsum. 



4. Stictocephala substriata Walker. PI. 1, fig. 20. 



Most nearly allied to the preceding but sufficiently distinct. 

 Metopidium convex, recurved for a greater space at apex and 

 meeting distinctly behind the humeri but much farther front 

 than in inermis. Pronotum low, the dorsum nearly rectilinear 

 but sloping posteriorly to the short acute apex which scarcely 

 attains the tip of the abdomen; face large, coarsely and evenly 

 punctured, with almost obsolete striae on either side of the base; 

 the clypeus scarcely longer than the arcuated cheeks. Last 

 ventral segment of the female short, almost truncated behind, 

 with a small acute median notch. In this species there is a 

 black patch adjoining each coxa and the outer disk of the 

 femora is also black. Length 7mm. I have but little doubt 

 but this is the insect described by Walker as Thelia substriata. 

 His type was from Florida and I have received it from the same 

 state and from New Jersey, North Carolina and Georgia. 



5. Stictocephala festina Say. PI. 1, fig. 28. 



This species, as I identify it, has about the size and form 

 of lutea but may be distinguished by its having the metopidium 

 more or less angled either side. Three forms occur in our 

 territory that I cannot distinguish as distinct species. That 

 most generally received from correspondents has the metopidium 

 slightly and very obtusely angled in the males, more strongly 

 angled in the females, its surface transversely strongly convex, 

 its lateral carinse distinct anteriorly, meeting considerably be- 

 hind the middle of the dorsum before which they become ob- 

 tusely rounded off; acuminate apex of the pronotum decurved
