the male. Pronotum greenish yellow, a black band on anterior third, another 

 narrower band margining the pronotum behind and covering about half of 

 the scutellum. Elytra greenish yellow, the sutural margin, claval suture 

 and apical margins narrowl}' fuscous in the female, a subhyaline area extends, 

 obliquely l)ackwards from the costal margins. In the male, and sometimes, 

 in the female also, these markings are all much broader and there is a fuscous 

 patch in front of the subhj-aline area connected internall}' with the apical 

 margin by two oblique fuscous lines. Face with upper half smoky in female, 

 black in the male, the lower half pale yellow, sometimes a narrow black 

 margin below in male. Sometimes females are found marked like the males, 

 throughout. 



Genitalia : lemale segment the length of preceding, posterior margin 

 straight or ver}- slightl}- emarginate ; pygofers rather long, constricted behind, 

 and much exceeded by the slender ovipositor ; male valve equilaterally tri- 

 angular, not quite as long as the ultimate segment and one-third as wide ; 

 plates but little longer than the valve, together nearly semicircular, their 

 margins clothed with long hairs which are slightly exceeded by the light 

 margined pygofers. 



Habitat: D. C, N. J., Md, Va., N. C, Fla., 111., Iowa, Neb., 

 Kans., Mis.s., Cuba, Hayti, St. Vincent, Vera Cruz, Mex., and 

 Para, Brazil. This is a very widely distributed species and as is. 

 usually the case varies much in size and color in different locali- 

 ties. Specimens are at hand from Hayti that average much 

 smaller and paler than ours and on the other hand specimens, 

 from Vera Cruz are very large and most of the females have the 

 black marking of the male type.

Size and form of bicolor ; testaceous, four black spots on vertex, a sub- 

 marginal row on pronotum and the apical veins black. Length, 9 3 5 nun-, 

 $ 3 mm.; width, i mm. 



Vertex very slightly longer and narrower than in bicolor, distinctly longer 

 than its basal width. Head with the eyes inclo.sing more than half of the 

 pronotum. Elytra narrower than in bicolor, apex narrowly rounding, not 

 reaching to the apex of the ovipositor in the female. 



Color : vertex pale testaceous, a pair of round spots on a line with the 

 anterior margin of eye and another smaller pair behind them. Pronotum 

 testaceous, a row of irregular spots on the anterior submargin ; scutellum 

 with a pair of .spots within the basal angles. Elytra testaceous, subhyaline 

 towards the apex, with the nervures bounding the apical cells fuscous. Face 

 testaceous, the apex of clypeus fuscous, Sometimes in pale specimens the- 

 fuscous spots are nearly all wanting, while in dark ones the anterior pair o\x. 

 vertex are much enlarged and the face may be darkened above.
