110 IIEVISION OF STMPETES AND HEL^US, ETC., 



near base, with posterior outline steeply slo|)iT)g (iiot overhanging) 

 to the base. Scutellum transverse, triangular, and gianulose. 

 Elytra very convex, as wide as long (11 mm.), widest beliind 

 middle, .slioulders bluntly rounded, foliate margins wide and 

 concave at base, strongly narrowing towards apex, becoming 

 horizontal in that region, exti-eme edge (seen sideways) wider 

 than that of prothorax, concave and gradually narrowing from 

 base to apex, obsolete behind; margins and disc closely set with 

 short upright black bristles. Disc strongly tricostate, sutural 

 costa extending from scutellum to &\)Qx; two parallel costse, one 

 on each elytron (3'5 mm. apart), more strongly raised than sutural 

 costa at base, abruptl}'^ ending on apical declivity, coarsely and 

 inegulaily |>unctulate on disc, margins impunctate, with faint 

 intlications of raised longitudinal lines on disc outside costse, and 

 a more or less continuous line of raised linear granides on the 

 outside of disc, forming a low crenulate costa. Abdomen very 

 finely and longitudinally rugosely punctate; under side of margins 

 coarsely punctulate, prosternum transversely rugose, submentum 

 finely granulated; le^js (especially tibiae) thickly granulated, tibial 

 spurs much shorter than in //. Gilesii; prosternum convex, with 

 posterior process rounded and margined, and only slightly pro- 

 duced. Dimensions 16 x 11 mm. 



Hab. — Perth, West Australia. 



A single speciDien((J), sent by Mr. W. Duboulay. A specimen 

 in the Macleay Museum is paiied witli another species labelled 

 //. Mastersii Pasc It is superficially like both //. Gilesii and 

 the specimen from 8alt River, W. A., which, Mr. Masters assures 

 me, is a cotype of //. Mastersii Pasc; but the last has red bristles 

 (though described with black), and the side edge of pronotum is 

 concave and equall}' as wide as that of the prothorax; with wider 

 anterior processes to the prothorax, and wider lateral margins; 

 H. opacicollis is strongly differentiated from //. Gilesii by its 

 opaque granulated head and prothorax, intei' alia. 



Hel^us spausus, n.sp. 



Elongate-ovate, subparallel, depressed, subnitid, piceous-black, 

 with foliaceous margins yellowish on the prothorax and in
