The thorax is not as wide as the elytra, and is strongly narrowed 
behind the middle, making the margin sinuate. The anterior angles 
are rounded and the posterior obtuse. The sides of the thorax are nar- 
rowly expanded and recurved, leaving a gutter-like margin along the 
whole length. It is not margined behind. The disk is very slightly 
pubescent, and sparsely and faintly punctured, most distinctly poste- 
riorly. A little behind the middle, upon each side of the So line, 
is a large conical fovea, but there is no median ridge or groove. A 
strong, erect hair occurs in front of the posterior angle, and another 
behind the anterior, and two or three short hairs follow the latter. 
The elytra are coarsely and irregularly punctured, and sparingly 
pubescent, with short stiff hairs. The surface is diversified by four or 
five obscure and irregular ribs, of which the outermost is largest, and 
forms a well-marked longitudinal angle. his and the one next it unite 
anteriorly in a prominent humerus. The edge of the elytron is recurved 
like that of the thorax, forming a still deeper gutter just within the 
margin. 
- ‘The thorax and elytra are commonly brownish green or grassy 
green throughout, but the humeral angles are occasionally touched with 
brow n, as is likewise the smooth scutellum. The sutural line is also 
sometimes brown. ‘The epipleurze are green, and do not attain the tips 
of the elytra. The legs and under surface of the body are pubescent ex- 
cept the prosternum, which is smooth, or nearly so. The abdomen is 
sparsely punctured. ‘The thighs are usually green, but the tibia, the 
tarsi, and the sides of the metasternum are more or less deeply tinged 
with brown. 
Egg (Plate XV., Fig. 1)—The egg is of a dirty white color and 
very minute, .025 of an inch in length and .015 of an inch wide; nar- 
rower at one end than at the other, having in fact almost precisely the 
shape of a hen’s egg. Under the microscope the surface is seen to be 
thickly dotted with minute hexagonal pits, about twenty in its entire 
length, and under a higher power the bottom of each of these pits ex- 
hibits still more minute de pressions, seven or eight to each reticulation.
