liV 11. .1. CAIiTKU. 229 



humeral gibbus prononneed, intervals flat, except the sutural, 4th, 8th, and 12th, 

 these wider than the rest and more or less costate, the sutui-al eosta l)ifurcating at 

 the seutelliim and continuous to the base; prosternum shaiply carinate and lightly 

 transversely rugose, basal segments of abdomen punctate and strigose, apical 

 segments very finely punctate. Dimensions: 21 — 22 x 10 mm. 



Hab. — Gingkcn. Blue Mountains (R . B. Carter), Blue .VIountains (Mr. 

 Deu(juet ) . 



Two examples show a species that I have hitherto hesitated to distinguish from 

 memnoniits Pase. (= tristis Germ.), but with the information lately acquired from 

 examples sent by Mr. Blair, it is evidently not that species. It belongs tj 

 Macleay's Sect, ii.. Sub-section 1, and is neai'est to the Ta-smanian species P. 

 reichei Breme, from which it is chiefly distinguished by (1) more nitid surface, 

 and wider form, (2) more clearly channelled and foveate proiiotum, (3) narrower 

 elytral margins, (-1) considerably larger seriate punctures. 



Type in Coll. Carter. 



Helaeus latifolius, n.sp. 



Widely obovate, sub-nitid brown black, elytra with short upright fine bristles; 

 tarsi, apical joints of antennae and tarsi reddish, underside opaque black. Heaii 

 densely and fuiely ]5unctate, antennae with 3rd joint as long as 4th-5th combined; 

 joints beyond 8th wanting. Prothurax 5X9 mm.; foliate margins wide, in d' 

 arcuately narrowed from base to apex, in ? expanding in front of base, thence 

 widely rounded to apex; disc and margins very flmely and sparsely punctate; the 

 punctures on margins bearing each a short bristle, foliate margins a little concave 

 and raised at the edges, anterior processes concave above, overlapping and 

 lather sharply rounded at apex, posterior angles falcate and overlajiping elytra; 

 disc with feebly-raised carina terminating behind in a small, narrow, rounded knob 

 in front of ba.se, the latter widely l)!sinuate. S'cutellum widely transversely oval. 

 Elytra of same width as prothorax at base and more than twice as long; obovate, 

 shoulders obtusely rounded, margins wide, concave and reflexed, more minutely 

 setose than those of tlie prothorax, each elytron separately rounded at apex, disc 

 with suture carinate and two strongly raised carinate costae, these sub-parallel, 

 less than 2 mm. apart, slightly diverging at scutellum, and suddenly terminating at 

 apical third ; space between costae, as also area between costae and margins, 

 coarsely punctate, each puncture producing a short reddish bristle, the extra- 

 costal spaces with two or three ill-defined longitudinal ridges. Abdomen densely 

 punctate, prosternum finely shagi'eened, e|iipleurae coarsely and closely punctate. 

 Dimensions: 18 X 21} mm. 



Hab. — Margaret River, Western Australia (Mr. .J. Clark). 



Two examples, the sexes, show a species near H. ijilesi Cart., but diftVriiig iu 

 ;1) much wider foliate margins of prothorax and elytra, (2) shorter and less 

 widely separated elytral costae, (3) much more coarse punctures on both elytra and 

 epi]i!eurae. Though the dimensions appear the same as those of II. gilesi, the 

 species is really more elongate and nearer II. frenehi Cart, in outline, the width 

 bein" largely due to the very wide margins sliown by the following comparison. 

 In H. gilesi the width of body and of combined margins are ft and 2 mm. respect- 

 ively. In n. latifolius the corresponding widths are 7i and 3} mm. 



Type c? in Coll. Carter; ? in that of Mr. Clark. 



Men'farchus, n.gen. Tenebrioninarum. (Text-fig 3.) 

 Lightly obovate, depressed; antennae long (extending nearly to base of pro- 

 thor.ix), 3rd joint very little longer than 4th, apical joints widely oval and flat-
