pubescence along middle of under-surface; three basal seg- 

 ments of abdomen each with a conspicuous medio-apical spot 

 of moderately long subochreous hairs. 



Head with a narrow median line somewhat dilated and 

 abruptly terminated near base; clypeus with some large 

 punctures and very minute ones, suture semi-circular and 

 partially concealed by pubescence. Antennae extending to 

 or slightly passing apex of elytra, fourth and fifth joints 

 slightly, sixth to tenth acutely produced on one side at apex, 

 eleventh joint about one-fourth longer than tenth. Pro- 

 fit ora.i: about twice as long as the apical width, which is 

 considerably less than that of the base, sides subangularly 

 produced in middle, strongly transversely corrugated, but 

 irregular about middle. Elytra about one-fourth wider than 

 prothcrax, feebly diminishing in width to apex, where each 

 is strongly emarginate and acutely bispinose ; basal third with 

 dense and coarse punctures, becoming much smaller pos- 

 teriorly; each with three feeble elevations, of which the outer 

 one is rather short and scarcely traceable. Length ( $ , 9)' 

 14-25 mm. 



Q . Differs in having shorter antennae and legs, femora 

 not densely clothed along under-surface (although more 

 densely than is usual with females of the genus), and abdomen 

 without tufts on the three basal segments.

Fairly close to strigosus (whose male has very similar 

 abdominal clothing), but elytral pubescence more uniform, 

 prothorax distinctly shorter, and apical spines of elytra much 

 more acute. The pubescence on the head and sides of sterna 

 is denser than elsewhere ; on the elytra, to the naked eye, it 

 has a feebly lineate appearance, owing to the feebly elevated 

 lines; on the prothorax it varies in density and disposition, 

 on some specimens being almost uniformly distributed, with 

 but a very small medio-basal glabrous spot, on others the 

 spot is extended to appear as a narrow glabrous stripe ; but 

 on about half of the specimens before me the prothorax has 

 four conspicuous vittae of pubescence, with the intervening 

 spaces shining and almost glabrous. On the specimen from 

 Kellerberrin most of the elytral pubescence is stramineous : 

 two small Victorian specimens have the elytral clothing 

 decidedly sparse. The false suture of the eleventh joint is so 

 distinct on some specimens that their antennae appear to be 

 almost twelve-jointed.
