62 REVISION OF THE SUBFAMILY TENEBRIONINJE, 



western forms in the very different elytral sculpture. The three 

 apical joints of antennae are wanting. Type in the National 

 Museum, Melbourne. 



A second specimen, labelled W.A., measuring 21 J x 9 mm., is 

 in the consignment of insects sent by Mr. Blair from the British 

 Museum; both are, I think, males. 



Hypaulax Spenceri, n.sp. 



Oblong-ovate, nitid black above and beneath, antennse piceous 

 (reddish towards apex), tarsi clothed beneath with red hair. 



Head distinctly punctate, epistoma and canthus coarctate, the 

 canthus shorter and more knobbed than in //. insularis Hope, 

 forehead very convex, ridged at the sides, with a horseshoe-im- 

 pression ; antennse moderately enlarged at apex. Prothorax 

 5x6-5 mm., slightly wider behind than in front, apex sub- 

 truncate, the widely rounded anterior angles scarcely advanced, 

 widest behind middle, sides widely diverging to the widest part, 

 then rather abruptly but not angularly converging (subsinuately) 

 to the obtuse undentate posterior angles; base truncate; lateral 

 border rounded, thick, raised and nitid, forming a sulcate channel 

 within, its extreme outline faintly crenulated, basal border thin 

 and accentuated by a transverse sulcus meeting the lateral sulcus 

 at the angles; disc more convex than in H. insularis, with a 

 faintly impressed medial line, a fovea on each side of this, and a 

 larger depression between the foveae and the sides at their widest; 

 minutely and closely punctate. Scutellum very transverse and 

 thin. Elytra slightly wider than the prothorax at base, obovate, 

 with nine rows of large, elongate fovese placed in deep sulci, the 

 ninth on the lateral sulcus only distinctly punctate anteriorly, 

 the intervals narrower and more convex than in H. insularis; 

 minutely punctate; suhmentum finely transversely rugose, gular 

 furrow well marked; prosternum coarsely rugose-punctate ante- 

 riorly, its process very convex, and not raised at apex; meso- 

 sternum and abdomen coarsely punctate and longitudinally 

 rugose; mandibles bifid at apex. Dimensions, 16x7 mm.
