186 REVISION OF PTEROHEL^US (contd.) AND SARAGUS, ETC., 



gulai" in the lateral regions, extremely fine and subobsolete at 

 base. Prosfeniiu/i rather coarsely granulose, central carina 

 sharp and strongly raised, abdomen finely striolate, with 

 apical segments minutely punctate. /Jl/iiitixio/is, 10-2 x 5-8 

 mm. 



I/nh. — West Australia. 



A single specimen, sent by Mr. C. French, sex doubtful, 

 is before me. The species is evidently nearest to /■*. nifidi.<<- 

 $imus Pasc, in size, and general facies, but differs from that 

 species in (1) the much finer and more confused punctuation 

 of the elytra ; (2) more reflexed prothorax ; (3) narrower 

 apical margins of elytra : and thus is placed under a different 

 Sub-Section in the tabulation. 



Pterohel^us subpunctatus, n.sp. 



Oval, black, opaque above, nitid-black beneath, antennae 

 piceous with apex ferruginous, tarsi and tibiae clothed with 

 light eastaiieou.s jtile. 



Head rounded and slightly raised in front of epistoma, 

 with a well marked circular grove limiting epistoma behind, 

 canthus raised and round : eyes large, transverse, and separ- 

 ated by a space of the width of the diameter of one, with 

 very shallow, scarcely evident punctures on front ; antennae 

 just reaching base of prothorax, with four apical joints sub- 

 clavate and flattened, rrafliord-r A x 75 mm , length mea- 

 sured in middle ; arcuate-emarginate at apex, widest at base, 

 sides very slightly rounded and converging from base to 

 apex, inflected at hind angles ; anterior angles widely 

 rounded, but produced in front of eyes ; posterior angles 

 acute, but rounded at tips and slightly produced backwards, 

 foliate margins strongly reflected, with extreme border thick- 

 ened and shining, central line distinctly shown, disc appar- 

 ently quite impunctate. Srtitclhim equiangularly triangular. 

 Eh/ira convex, slightly wider than prothorax at base, shovil- 

 ders widely rounded, sides subparallel, but a little widened 

 behind middle, margins of nearly uniform width throughout
