out, more thickly towards the margins, and a transverse curved se- 

 ries of larger punctures behind ; elytra strongly dilated at the base, 

 very near to which is their broadest part, from thence gradually nar- 

 rowed to near the apex, when the curvature of their sides is greatly 

 increased, each marked with ten rows of large deep punctures, each 

 of the interstices having a remote series of minute punctures and a 

 continuous line of the same near to the suture, the larger punctures 

 dark ; under side pale, the ventral laminae rather faintly punctured ; 

 legs paler.

Ferrugineus, nitidus, elytris profunde punctato-striatis, inter- 

 stitiis seriebus punctorum minorum, thorace antice angusto, lateribus 

 rectis, elytrorum, quorum maxima latitudo pone basin locatur, par- 

 tibus intermediis laterum subparallelis. (L. c. lin. 1-^.) 



Dull red ; head and thorax as in H. ferrugineus ; elytra strongly 

 dilated at their base, very near to which is their broadest part, but 

 they decrease very slightly in width until past their middle ; punc- 

 tured as in H. ferrugineus, the larger punctures and numerous 

 blotches dark, forming two interrupted oblique fasciae upon each 

 elytron, meeting at the suture ; under side paler, the ventral laminae 

 more thickly and deeply punctured than in H. ferrugineus. 



Taken near Cambridge, but not in company with the preceding.

 lateribus rotundatis. (L. c. 2, lat. 1 — 1^ lin.)

Reddish yellow : head broad, minutely punctate ; eyes very slightly 

 prominent, black ; antennae pale, about equal in length to the tho- 

 rax, which is much narrowed in front, emarginate, the anterior 

 angles very acute, sides straight, slightly margined, not in continuity 

 with the elytra, posterior angles acute, the disc smooth, the margins 

 thickly punctate, and a transverse curved somewhat irregular series 

 of large punctures behind ; elytra strongly dilated at the base con- 

 tinuing slightly to increase in width for about 4 of their length, 

 from that point narrowing in a curve of continually increasing cur- 

 vature to the apex, punctate as in H. ferrugineus, all the larger punc-
