transversely sulcate, the sulcation neai-ly straight. Elytra obso-

ILab. India {Fair.); Assam {Chennell: coll. JBaly). 



Labrum shiuing black ; antenuse entirely flavous. Thorax 

 nearly twice as broad as long ; sides nearly straight and slightly 

 diverging from the base to beyond the middle ; disk transversely 

 sulcate immediately behind the middle, the sulcatiou straight. 

 Elytra slightly but distinctly depressed below the basilar space, 

 very minutely punctured. Hinder femora in the male slightly 

 stained on their outer surface with piceous. 



The entirely black abdomen, together with the entirely dif- 

 ferent structure of the anal segment of the abdomen, will at 

 once separate this species from A. foveicollis and A. ahdominalis, 

 with which insects it is usually confounded; it also differs from 

 both in the depression below the basilar space of the elytra.

Hah. Malay Peninsula, Penang, Tringano, Malacca. 



Antennae from the second to the tenth joint slender, filiform 

 (the terminal joint broken off). Thorax nearly twice as broad 

 as long ; sides nearly straight and slightly diverging from the 

 base to beyond the middle, thence obliquely converging towards 

 the apex ; upper surface smooth, very finely punctured on the sides; 

 discoidal sulcation nearly straight, deeply impressed. Elytra much 

 broader than the thorax, dilated posteriorly ; convex, transversely 

 excavated below the basilar space, very minutely punctured. 



Similar in form to A. lata, differing in the colour of the thorax 

 and lower surface of the body, which is uniform in the three spe-
