ANTHONOMUS SOPORUS. 
PL x1, Big 
Anthonomus soporus Scudd., Tert. Ins. N. A., 472-473, Pl. vi, Fig. 16 (1890). 
Body rather stout, strongly arched, rapidly tapering in front of the 
elytra, which are but little broader in the middle than at base. The head 
is about a third higher than long, moderately full, punctate; eyes moder- 
ately large, circular; beak considerably longer than the prothorax, faintly 
arcuate, equal, punctulate. Prothorax a little higher than long, tapering, 
a little full, faintly punctate. Klytra much larger at base than the pro- 
thorax, with nine equidistant, rather coarse, not greatly elevated, coarsely 
beaded ridges (representing by reversal punctate strize) besides the sutural 
ridge, the third and fourth from the sutural ridge being a little shorter 
than the others which increase regularly in length from within outward; 
the smooth flat interspaces are fully twice as broad as the striz. 
The specimen from White river seems to have a stouter rostrum, but 
is apparently of the same species with the others.
