closely and vrry coarsely puncttired, a little depressed loiij^i- 

 tiidiiially in tlie middle, its b:i.se tninciite ; it heiirs some 

 erect iufuscnte setic at the sides. Elytra suhcordate, of (lie 

 same width as the thorax at the base, widest near the middle, 

 apex nnieh narrowed and nearly vertical ; they have series 

 of relatively coarse punctures, coarser at the sides than at 

 the suture, and becoming? striate behind ; the interstices 

 beyond the second row of sutural punctures apj)car some- 

 what elevated from base to apex; there are no s(juam:c, 

 only a few eoarse erect set;e. I^^'QS stout, coarsely setose, 

 apical hooks of the tibiie well dcvclo|)ed. 



Underside black ; basal ventral sej^ments coarsely but not 

 closely punctured, second barely half the length of the first, 

 the suture indistinct ; third and fourth very short, with dec|) 

 sutures; fifth I'cddish, minutely sculptured. Pectoral canal 

 profound, its raised hind mar<.;;ins extending to the middle of 

 intermediate coxie. Metasternum very short. There are no 

 distinct ocular lobes. 



The plain black colour, absence of squamosity, and rather 

 long medially depressed thorax are distinctive cliaractcrs.

Rostrum stout, gradually narrowed medially, with many 

 depressed greyish scales which arc j)crceptil)ly separated from 

 each other. Thorax apparently longer than broad, widest 

 behind the middle, gradually narrowed towards the front, 

 base truncate ; the surface punctate and studded with erect 

 scale-like setai. Elytra slightly wider than thorax at the 

 base, moderately short and broad, only a little broader near 

 the middle than el>ewhere, rountlcd and nearly vertical 

 biliind, distinctly striate-punctatc, their clothing similar to 

 that of the thorax. Leys stout, almost as coarsely setose as 

 the body. Tarsi with fine, white, brush-like soles, their 

 third joint moderately dilated, with well-developed lobes. 



A. alhitttriyali.^ is a rather smaller and narrower insect,
