The tubercles on the prothorax consist of two near the base 

 (which are opaque), and three nitid (of which the middle one is 

 very small), so placed as to form with the lateral teeth a con- 

 tinuous row. 



This species must be near A. Howitti, Pasc, but seems certainly 

 distinct, that insect being described as of a fulv^ous-brown colour, 

 with pale legs and antennae ; its scutellum is said to be narrowly 

 triangular, and there is no mention of anything like the con- 

 spicuous crest-like ridge into which the 4th (from the suture) row 

 of tubercles is elevated at the base of the elytra (a character that 

 Mr. Pascoe could hardly have passed over unnoticed). From 

 A. rugosulus, Guer., the only other large species of black colour 

 with the prothorax almost impunctulate, the present insect differs 

 by the truncate apex of its elytra.

 Perfectly fresh specimens are sparsely sprinkled with extremely 

 fine short erect hairs and closely covered with a very tine silky 

 pubescence, the conspicuousness of which depends on the position 

 in which the light falls on it. This pubescence is more fulvous 

 on the prothorax and more whitish on the elytra, and it leaves a 

 large denuded spot on either side of the base of tlie prothorax, 

 and a smaller one on either side at the front margin. The 

 sculpture of the elytra is extremely difficult to describe ; the 

 surface seems to be somewhat irregularly punctulate-striate, tlie
