Prothorax transverse, half as wide again as long, apex emarginate, 

 anterior angles widely acute and prominent, extending to the 

 eyes; sides widely rounded, widest behind middle, then sinuately 

 narrowed at posterior angles, these turned downwards and 

 outwards forming a subrectangular tooth. Base truncate. 

 Disc densely coarsely rugosely punctate, punctures tending to 

 coalesce and to become striolate on the foliaceous margin (this 

 margin concave and reflexed). The whole pronotum concave 

 and reflexed on the sides. Scutellum triangular with apex 

 raised, punctate. Elytra wider at base than prothorax at 

 widest; convex, with shoulders round and subrectangular; sides 

 slightly bulging about half-way, apex bluntly acute. Interruptedly 

 striate-punctate, striae reticulated by transverse lines, forming 

 series of rectangular fovea 3 , each filled with coarse punctures. 

 Intervals raised, crenate and shining, becoming more interrupted 

 towards the sides and apex (as in A. porcatum Fabr.), mere lines 

 of pustules towards apex. Epipleura3, last two segments of 

 abdomen and legs closely punctate, the rest of abdomen with a 

 few much finer punctures. Fore and intermediate tibiae slightly 

 curved and thickened at apex, hind tibiae straight. Whole legs 

 densely pilose. Dimensions — <J 12 5x5 mm.; Q 14 x 6 mm. 



Loc. — Endeavour River, Dawson River, Port Denison, Q.

The above insect is unnamed in the Macleay Collection, speci- 

 mens of which have been courteously supplied me by Mr. Masters. 

 While belonging to the A. porcatum and A. augur ale group, it is 

 easily distinguished from these by its smaller size, different 

 colour, and its pilose clothing, which is thickest on the head and 

 pronotum, and more thinly distributed on the elytra. In size and 

 facies it approaches A. cozruleum mihi, from which species it 

 differs widely in colour and its elytral sculpture. In its lateral 

 prothoracic foliation it resembles A. reticulatum mihi. The pile 

 is much shorter than in A. pilosum Pasc, to which insect it other- 

 wise bears little resemblance. 



From A. tropicum Blackb., it evidently differs in size and 

 punctate elytra ; also of that species Mr. Blackburn says,
