 circular impression on each side ; surface hairy, behind lateral 

 horns very slightly convex. Tegmina very broad, vitreous yel- 

 low, veins darker, base coriaceous, with a piceous oval spot, a

lu some examples the two anterior black spots coalesce, 

 the entire front of the head is irrorate or black, and the carina 

 is posteriorly more or less piceous.

 yellow except apex, which is black ; the black markings in 

 front faded to two light ferruginous mottled spots ; external 

 surface of lateral horns same as in £, the ferruginous lines 

 mottled with the ground color, tip not black ; prothorax very 

 hairy. Tegmina much darker vitreous yellow, piceous spot at 

 base much larger and punctured. Below, same as 5. Abdomen

In this species the median carina is percurrent, nearly obso- 

 lete anteriorly ; the tips of lateral horns lightly recurved. It 

 is more depressed anteriorly than any species known to me. 

 The line formed by the union of the vertical with the superior 

 triangular surfaces is lightly convex in the i. In the $ it is 

 convex in the middle and concave on each side. Near the base 

 of the prothorax, on each side, is a transverse smooth impres- 

 sion.
