 darker, the ventral laminae deeply punctured ; legs paler.

Fusco-flavus, nitidus, elytris profunde punctato-striatis, intersti- 

 tiis seriebus punctorum minorum, thorace elytrorumque lateribus 

 subparallelis parte antica hujus etapicali illorum exceptis. (L. c. 2, 

 lat. 1— 14- lin.) 



Dusky yellow ; head short, very broad, thickly and rather deeply 

 punctate ; eyes prominent, black ; antennae pale ; thorax but little 

 narrower in front than behind, slightly emarginate, sides nearly 

 straight except near the anterior angles, where they are rounded, 

 slightly margined, not in continuity with the elytra, the posterior 

 angles but httle less than right angles, thickly punctured, with a 

 smEdl space on the disc smooth, and a transverse slightly irregular 

 straight series of large punctures behind ; elytra strongly dilated at 

 the base, the sides then continued nearly parallel but in most cases 

 narrowing slightly for about three fourths of their length, afterwards 

 quickly attenuated to the apex, punctate as in H. ferrugineus, the 

 larger punctures and frequently the suture dusky, that colour often 

 suffused so as to give the appearance of a transverse fascia at the 

 base, and a cloud on each elytron towards the apex ; under side 

 rather paler, the ventral laminae deeply punctate ; legs paler.

5. H. RUBicuNDus, Spence MSS. ? Bab. Plate XV. fig. 6. 



Ferrugineus, nitidus, ovalis, elytris profunde punctato-sti'iatis, 

 interstitiis seriebus punctorum minorum, thoracis elytrorumque la- 

 teribus in eadem arcu. (L. c. 1-^, lat. 4 lin.) 



H. ferrugineus, y. Stejjh. 1. c. supra. 



Dull red ; head short, broad, minutely punctured, the vertex 

 smooth ; eyes scarcely at all prominent, black ; antennae red ; thorax 

 much narrowed in front, with its lateral margins very slightly 

 rounded, and so nearly in continuity with the elytra, which are but 

 little dilated at their base, as to give the insect's outline the appear- 

 ance of forming a uniform curve, the whole approaching very closely 

 to the ovate form, the disc smooth, the margins thickly punctate, 

 the transverse series behind not so distinctly marked as in the three 

 preceding species ; elytra but little dilated at the base, gradually in- 

 creasing in width for about one third of their length, then decreas-
