312 AUSTRALIAN COLBOPTERA : XOTES AND NEW SPECIES, 



■Wise nitid and impunctate; underside rather coarsely punetured. Dimensions: 

 2x1 (vix) mm. 



Hab. — Tambourine Mountain, Queensland. (A. M. Lea). 



In describing P. bicolur (Trans. Roy. Soc. S. Aust., 1914, p. 225), while 

 noting the difference of colour in the examples, I failed to notice that these 

 represented two distinct species of which the description applies only (except 

 ii) colour) to the darker species, with black head and pronotum with the an- 

 tennae 4-elavate. P. triclavatum was taken in company with bicolor, by sifting 

 leaf refuse. Besides colour difference and antennal joints, the prothorax is 

 narrower, the sides straighter, the size smaller and more convex than in bicoJor. 

 Type in Coll. Carter. 



N.B. — Both species will probably bo found to require generic distinction 

 from P. bneins and P. integricollis, but at present I am unable to give well-de- 

 fined characters to separate these groups. 



, Pterohel.4j;us pae\i-punctatcs, n. sp. 



Ovate, depressed, nitid black, antennae and tarsi red. 



Head densely and clearly punctate, antennae with last tour joints flattened 

 and sub-circular. 



Prothoraj- areuate-emarginate at apex, anterior angles well produced and 

 rather sharply rounded at apex, sides arcuately widened to base, posterior angles 

 sharply falcate; foliate margins wide and concave, extreme margins reflexed, 

 base bisinuate, disc very minutely punctate, smooth along middle, basal foveae 

 rather deep. 



Scutellum curvilinear-triangular. 



Elytra of Same width as prothorax at base, sides nearly straight on basal 

 half, widely rounded behind, foliate margins wide, narrowed on apical third, 

 thence narrowing to apex, seriate punctate, scarcely striate, with about IG rows 

 of small punctures (besides a short scutellary row), obsolescent at apex, inter- 

 vals ((uite flat and almost impunctate; the 1st, 5th and 0th slightly wider than 

 the rest; pro- meso- and nieta-sternum finely transversely rugose, abdomen rat lier 

 deeply longitudinally striolate. Dimevsion.s : 17 x OJ mm. 



Hah. — Camooweal, North Queensland. 



Two specimens had been long hypothetically labelled "()emi)iafiis'' VAiu-kh. 

 in my collection. There is also a specimen in the British Museum. It is, how- 

 ever, a much flatter insect than P. c/eminatuf, and is nearer P. }}ln)iii.'< Hless. l>ut 

 has a more nitid surface, smaller seriate punctures, and proportionally wider 

 margins to elytra. Only under a Zeiss l)inocuUir can I make out punctures on 

 the elytral intervals. The seriate punctures, though fine, are (|uite regular and 

 there are no areas of irregular puneturation as in P. disperstis Macl. and others. 

 From /'. dnrlinfjensifi milii it differs in smaller size, wider margins, and finer 

 sculpture throughout. Type in ('oil. Carter. 



Saragus pronus, n. sp. 



Ovale, depressed, nitid black, tibiae jiiceous, antennae and tai-si red. 



Head very minutely punctate, antennal orl)its strongly raised and earlike, 

 clypeus truncate in front, only separated from forehead by line oblii|ue side 

 furrows, antennae with joint 3 twice as long as 4, the la.st three joints oval and 

 fl.'ittened.
