OF PHILADELPHIA. 283 



generic with the mollis, owing to the conforuiatioii of the first 

 joint of the tarsi, which agrees with that of the present genus. 

 The antennae are much less serrated than those of clotif/afus Fabr., 

 and are proportionally longer, the nails also are pectinated.

 .Spin. — Lec] 



CLERUS Fabr. Dej. 



1. C. TRIFASCIATUS. — Rufous; elytra with a broadband on the 

 middle, and tip black, an intermediate cinereous band. 



Body hairy, bright rufous : head at tip dusky : antennae black, 

 terminal joint rufous at tip : thorax short, the transverse inden- 

 tation rather deep : elytra rufous and granulated at base; on the 

 middle a much dilated deep black band, undulated on ita anterior 

 and posterior edges, and with a narrow cinereous line at its ante- 

 rior edge; behind this black band is a pale rufous band so covered 

 by cinereous hair as to appear entirely cinereous ; tip deep black : 

 beneath rufous: feet hairy, black. 



Length more than nine-twentieths of an inch. 



This insect has considerable resemblance to the ichueumoneus 

 Fabr., and ru/iis Oliv., but the black band occupies the situation 

 of the rufous band of those insects, behind this band these two 

 species have [176] a black band, but in our insect this is rufo- 

 cinereous; the tip also is deep black, whereas in the above men- 

 tioned species, it is either spotted or margined with cinereous.
