eyes approximate. Thorax transverse, the margins very broad and 

 dilated, very minutely rugosely punctate, opaque ; the anterior 

 angles crossing in front of the head and rounded at the apex, but 

 much less broadly rounded than in those of H. Colossus, the posterior 

 angles not much recurved ; the disk is convex, smooth, not per- 

 ceptibly punctate, and strongly carinate on the median line from a 

 little behind the apex to close to the base, the carina rising in a 

 compressed tubercle at its base ; the base of the thorax is bisinuate, 

 the edge near each side minutely serrate. The elytra are very 

 slightly broader than the thorax and nitid, the margins are broad, 

 smooth, impunctate and of a reddish hue with a very thick 

 upturned border, the disk is faintly punctate, with the suture 

 slightly carinate ; a very strong carina on each elytron near the 

 suture extending from base to apex, and a line of rather large bead- 

 like tubercles along each side on the marginal junction. Under 

 surface brown, very finely striolate, legs punctate, finely pubescent.

Entirely of a very nitid brownish-black, smooth. Head some- 

 what square ; clypeus not sensibly emai'ginate, labrum salient 

 feebly rounded, epicranium convex, forehead very slightly canali- 

 culate between the eyes. Antennfe as long as the thorax, in all 

 respects like that of H. perforatus. Thorax finely punctate, less 

 transverse than in the previous species, elongated antei-iorly and 

 rounded laterally, subsinuate behind, a very slight emargination 

 on each side a little above the postei-ior angles, the anterior angles 

 very long, crossing in front of the head and terminating in an 

 obtuse point ; the disk a little convex, the median line carinate, 

 more elevated behind ; margins broad, wavy, feebly folded on the 

 border. Elytra with a slight irregular punctiiration, a little 

 dilated behind the humeral angles, then almost parallel-sided to 

 two-thirds of the length and rounded at the apex, the disk very
