originating from the base, and extending along (but not 

 touching) the lateral margins for about two-fifths of the 

 entire length of the elytra. These markings, if the insect 

 be turned head downwards, assume somewhat the shape 

 of an anchor. Underside and legs bronzy. 



Head punctured, impressed between the eyes. Thorax 

 three-quarters as broad again as long ; anterior margin 

 straight, half as long as the base ; sides rounded ; base 

 nearly straight ; disk deeply and largely punctured ; just 

 above the posterior angle on each side is a small round 

 impression. Elytra punctate-striate, twice as long as 

 wide, the sides nearly straight till past the middle, whence 

 they are rounded to the apex, which is armed with two 

 strong external spines. Underside punctured, covered 

 thickly with long white hairs ; legs punctured.

 Thorax three-quarters as broad again at the base as long ; 

 anterior margin nearly straight, slightly elevated, half as
