Color: So variable that it can only be indicated under the varieties. 
Genitalia: Female pygofers, broader than long, the ovipositor only 
slightly exserted; male plates broad at the base, gradually narrowing to 
the middle, bey ond which they appear as tapering, finger-like processes. 
Habitat: Europe, the New England states, Nova Scotia, 
and Ontario. Uhler records it from Utah, Dakota, Sitka, and 
Lake Winnipeg, but it seems probable that those references 
were to one or more of the other species, as it has not been 
found by anyone else in any of these localities, while both 
hilineatus and abjectus have. 
In color this species is very variable; in Europe about 
fifteen varieties are recognized, ranging from pale, creamy- 
white, through variously spotted and lined forms, to a shining, 
jet black variety. These have not all been recognized in this 
country as yet, but as both the extreme, and several of the 
intermediate forms have, it has been thought best to give all 
the more strongly marked varieties indicating which ones are 
known to occur. 
These varieties all intergrade and no hard and fast lines 
can be drawn in regard to them, but nearly all the examples 
will fall readily in to one or another of the following ones, the 
greater number probably belonging to the first. 
Var. ustulatus Fall. Grayish-brown or tawny, the vertex and anterior 
half of the pronotum light, a large, light spot before the middle of the 
costal margin, and another, slightly smaller, behind. 
Var. fasdatus Pabr. Vertex and anterior half of the pronotum golden- 
yellow, the rest of pronotum and elytra dark-brown or black, with an 
oblique band from scutellum, broadening to just before the middle of costa, 
and a spot behind the middle, sometimes extending to a spot at apex of 
clavus, white. 
Var. marginellus Fab. Black; vertex and anterior half of the pronotum 
and a stripe on the costal margin of the elytra, yellowish-white. 
Var. leucocephalus Linn. Dark-brown or black, vertex and anterior half 
of the pronotum yellow. 
Var. lateralis Linn. Black; a broad, light stripe on costa. 
Var. leucophthalmus Linn. Entirely dark-brown or black. 
Var. Uneatus Fab. Yellowish-white; a median black stripe arising, 
sometimes on the point of the vertex, sometimes on the pronotum, and 
extending to the apex of clavus, often enclosing a narrow, light line; a 
dark stripe on the corium, parallel with the first. 
Var. pallidus Sch. Pale yellowish-white. 
Whatever its color, it may be readily separated from 
Uneatus by the broader, convex form, and the short, obtuse 
vertex.
