Resembles the preceding (II. rectangulus), but with a 

 very different prothorax, the hind angles viewed obliquely 

 from the side being seen to be entirely rounded off, while in 

 rectangtdus they are from all points of view sharp right 

 angles. Other differences will be noted by comparing 

 the descriptions. The trilobed outline of the head is well 

 defined, and is divided, but not so strongly as in rectangulus, 

 the middle lobe a little more than two-thirds of a lateral 

 lobe. Some specimens (apparently females) are a little 

 broader and more ovate than the others. The type described 

 above is a male.
