Hab. — Western Australia: Beverley (E. F. du Boulay). 

 Type, I. 10792. 



The sides of the prothorax are obscurely diluted with 

 red. There is a rather dense fringe of hairs overlapping the 

 base of the scutellum. The prothorax measures 8x5 mm., 

 but to the eye it appears twice as wide as long. Of the species 

 referred to A A, in Blackburn's table, it differs from soror in 

 being much smaller and darker, prothorax with larger punc- 

 tures, and third joint of the antennae of different shape; 

 heterodactyla is a larger and paler species, and its third 

 antennal joint has a spiniform process ; in hirtuosa, pilosa, 

 and australis the clothing of the head and prothorax is very 

 different; in assimilis the third joint of the antennae is much 

 longer, and the fourth of very different shape; from the 

 description of laticollis it differs in having the prothorax no 

 wider than in pilosa, the smaller elytral punctures not more 

 strongly impressed than the smaller ones of that species, the 

 size is smaller, colour darker, and clothing different. In 

 general appearance it is like a small dark verreauxi, but its 

 flabellum has one more joint than in that species. It is the 

 first true species of the genus to be recorded from Western 

 Australia.

 PI. xxv., fig. 21; pi. xxvi., fig. 48. 



d . Of a uniform and rather pale castaneous, some mar- 

 ginal parts and the tibial teeth darker. Clothed with fine, 

 depressed, pale pubescence, some longer hairs scattered about 

 on elytra, and becoming dense on parts of head and pro- 

 thorax ; sterna densely pilose. 



Head strongly convex and with crowded punctures 

 between eyes, becoming much larger and sparser on clypers. 

 Antennae ten-, flabellum six-jointed. Apical joint of ma: il- 

 lary palpi long, and with a narrow opaque furrow. Prothorax 

 moderately long (5'5-7'5 mm.), sides strongly rounded and 

 obtusely serrated, hind angles obtuse but not rounded off, base 

 lightly bisinuate; median line short and feeble; punctures 

 crowded but sharply defined. Scutellum with crowded punc- 

 tures. Elytra with dense punctures of two kinds : small, 

 shallow, and often transversely confluent ones, and consider- 

 ably larger and deeper ones. Pygidium shagreened and with 

 dense punctures. Front tibiae strongly tridentate, the second 

 tooth slightly nearer the first than third. Length, 20-23 mm.

On one of the specimens the sides of the prothorax and 

 the pygidium are infuscated, but this appears to have been 

 caused by partial decomposition. There is a dense fringe
