There is a general resemblance among these three first species 

 of the genus ; but each, as I have before noted, may readily be 

 separated. The punctuation of this species somewhat differs 

 from that of the preceding ; it consists of larger punctuations, 

 between which are more minute punctures : the pattern of the 

 markings of the elytra resembles much that of H. pidchellus, the 

 transverse fascia (in the single example before me represented by 

 a shorter band and a lateral insulated marking of black' is nar- 

 rower ; two sub-circular, adjacent, flavous spots are well defined, 

 one on either side of the suture in the midst of the triangular 

 basal marking of fuscous. In size this species corresponds with 

 H. pulchellus, in form it resembles H. orientalis. 



I have a single example in my cabinet, which I obtained some 

 years ago from Mr. Stevens, received by him from China,
