THE CANADIAN ENTOMOLOGIST. 239 



Front slightly convex, punctured, eyes distant in both sexes, antennae 

 very short, barely reaching the middle of the body in $, slightly longer in 

 o* , darkened towards the tip, thorax rather broad, slightly contracted 

 both front and rear, punctures almost invisible through the pubescence, 

 depressed behind with a fairly-developed lobe, hind angles much rounded, 

 leaving the remainder of the lateral edge almost straight, elytra parallel, 

 fairly regular, punctate striate, but much obscured by the pubescence, the 

 red markings seem indeterminate, but consist primarily of root marks on 

 ihe second, third and humeral intervals, a band below the humerus, run- 

 ning obliquely to the third interval, before the middle ; a transverse spot 

 at the middle of the side before the convexity, the tips and a spot just 

 anterior to it. The three $ specimens before me vary somewhat in 

 extent of markings, and the only £ has the spots considerably suffused 

 and spread out, so that the elytra are almost luteous, below and legs black, 

 more or less picked out with luteous on the usual places.

 eyes distant ( 9 ), thorax much wider than long, very much narrowed, or 

 almost compressed in front; transversely impressed behind, ante-scutellar 

 lobe not marked ; sides subangulate, sinuate behind, surface thickly 

 punctured, grossly so at the anterior angles, elytra moderately, regularly 

 striate, punctate, except the scutellar area ; entirely orange-yellow, except 

 a common sutural stripe which runs, from the base to a point in the suture 

 just over the edge of the convexity ; the rear ends are beveled to a point 

 from the outside to the suture, marginal stria moderately curved and 

 sinuate, lobe well developed, with a black edge and fine row of marginal 

 punctures, scutel piceous ; below and legs black, fossa ( 9 ) round, deep,
