base ; explanate margins wide and horizontal, extreme border 

 narrow and not raised, the whole densely and rather coarsely 

 punctate, a central depression scarcely indicated. Scutellum 

 transversely triangular, densely punctate. Elytra as wide as 

 prothorax at base and two and a half times as long, widest at 

 base, and very gradually narrowing hindwards, moderately 

 convex, lateral declivity from the suture pronounced, shoulders 

 slightly reflexed and obtusely angulate, horizontal margins 

 moderately wide and continuous to the apex, each elytron 

 separately rounded there ; seriate-punctate, with about 

 eighteen rows of moderate punctures placed at a distance of 

 the diameter of one (their size intermediate between those 

 of cyhndricus and elongatus, Macl.), the alternate intervals 

 subcostate (much less so than in P. elongatus), the punctures 

 becoming confused and irregular at base, and obliterated at 

 apex, a smooth space on each side of suture. Submentum 

 rugose, prosternum coarsely transversely rugose, metasternum 

 pustulose. Abdomen and legs rather coarsely and closely punc- 

 tate ; anterior tarsi very wide. Dimensions — 19 x 9 mm. 

 Hab. — Queensland: Rockhampton (Captain Sumter). 



A single specimen, male, in the Australian Museum, 

 Sydney, is another ally of P. elongatus, Macl., but differs 

 in having a strongly punctate pronotum, its alternate intervals 

 less sharply costate, and its tapering form inter multa alia. 

 Type in Australian Museum, Sydney. 



Pterohel^eus vestitus, n. sp. 



Shortly ovate ; cinnamon-brown ; the whole surface above 

 and beneath clothed with pale-reddish recumbent hair; tarsi 

 and antennae red. 



Head — Epistoma short, rounded, its suture straight and 

 finely marked ; eyes small, widely separated ; antennae short, 

 the last four joints enlarged. Prothorax 2x4 mm., semi- 

 circularly-emarginate ; the acute anterior angles extending in 

 front of the eyes, base strongly bisinuate, posterior angles 

 produced backwards and rather widely acute ; sides evenly 

 rounded, explanate margins wide and horizontal ; disc minutely 

 punctate, the punctures obscured by the short hairy clothing; 

 a smooth medial line indicated. Scutellum curvilinear-tri- 

 angular. Elytra as wide as prothorax at base and three times 

 as long, ovate and convex, striate-punctate, the striae well 

 defined, the punctures therein small and close, intervals flat,
