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 narrowly fuscous in the female, a subhyaline area extends 
obliquely backwards 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 subliyaline area connected internally 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 very slightly 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. , Miss., 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 mm., 
S 3 mm.; width, i mm. 
Vertex very slightly longer and narrower than in bicolor, distinctly longer 
than its basal width. Head with the eyes inclosing 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, subliyaline 
towards the apex, with the uervures 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 on, 
vertex are much enlarged and the face may be darkened above.
