Hab. — Queensland: Cairns (A. M. Lea). Type (unique), I. 12615. 



In general appearance like a large specimen of O. (jrandis (the only other 

 Australian species having the prothorax black), but with longer and thinner 

 legs, knees very little darker than the adjacent parts, instead of conspicuously 

 black, and elytra of different shape ; on grandis they are distinctly wider than 

 long, with the sides almost evenly rounded, although narrower at base, on the 

 present species they are scarcely wider than long, and (with rounded outlines) 

 increase in width from base almost to apex. All the punctures are large and 

 sharply defined, but those on the prothorax are largest of all. 



Oedichirus cribriventer, n. sp. 



S . Blackish ; mouth parts, antennae, palpi, prothorax, and legs more 

 or less flavous. With long, straggling, ashen hairs. 



Head (excluding neck) transverse, with rather large and deep punctures. 

 Mandibles long and acute, each with a rather small acute tooth about the middle. 

 Antennae thin, none of the joints transverse. Prothorax scarcely as long as 

 the greatest width (almost at apex), sides strongly decreasing in width to 

 base, with large and irregular punctures, crowded in places, but leaving a rather 

 narrow and irregular median line. Elytra small, sides rather strongly rounded, 

 apex much wider than base ; with large and rather dense punctures. Abdomen 

 more than half the total length ; with large and dense punctures, becoming 

 oblong at the base of each segment on the upper-surface, and rather less so on 

 under-surface ; subapical segment with a shallow depression on under-surf ace, 

 its tip with a small and wide triangular notch. Legs rather long and thin, hind 

 tibiae subtriangularly dilated and notched near outer apex. Length, 7.5 mm. 



Hab. — Queensland: Gladstone (A. M. Lea). Type (unique), L 12616. 



Fairly close to O. geniculatus, but head black, legs entirely pale, elytra not 

 entirely pale and with rather more numerous punctures; O. rubricolUs has less 

 irregular punctures on prothorax, legs partly and elytra entirely dark, etc. ; O. 

 tricolor has red head and prothorax, etc. ; structurally it is close to O. grandis, 

 but prothorax, elytra, and legs are very differently coloured and the punctures 

 are somewhat different. At first glance the elytra appear to be as dark as the 

 abdomen, but on close examination the base, suture, and tips are seen to be 

 obscurely reddish.

Of this species I wrote to Mr. G. J. Arrow: "Specimens in my collection 

 seem very close to the British and Eviropean P. fiiscipcs, Curt., differing only 

 slightly in colour of legs. I would be glad if you would compare the type with 

 normal specimens of fuscipes (which has been recorded by Bernhauer as
