sutural angles. The male probably has tubercles on the 

 metasternum, these being- present in the same sex of the 

 nearly allied A. curvidens. The Venezuelan insect referred

? . Black, the elytra with an oblong spot at the base, a 

 small spot on the disc nt about one-third from the tip, a 

 transverse patch midway between the latter and the apical 

 margin, and the outer margin to about the middle, orange- 

 yellow ; the elytra bicostate, the apices broadly sinuato- 

 truncate, with the sutural angle produced inwardly into a 

 rather long tooth and the outer angle rounded; the other 

 characters as in the same sex of A. gorhami, A. antillamm, 

 lebasi, &c. 



Length 7, breadth 3 mm.

One worn female, too different to be included under any of 

 the allied forms as a colour-variety (the third spot on the 

 elytra small and the second wanting altogether), owing to 

 the broadly sinuato-truncate apices :o£ the elytra and the 

 inwardly-produced dentiform sutural angles.
