Head with rather large, somewhat obsolete, punctures. 

 Rostrum rather coarsely punctate along dorsal ridges and on 

 sides ; not excavate above, with a deep median linear sulcus, 

 dividing the surface into two parallel ridges. Eyes small, 

 round ; their anterior margin almost impinging on base of 

 rostrum. Antennae with second funicular joint longer than 

 the first. Prothorax (3'5 x 3 mm.) almost oval as viewed from 

 above, convex ; as viewed from side, strongly produced 

 upwards and forwards to apex, then turning downwards to 

 form -a large hood- or cowl-shaped median lobe enclosing head, 

 the cavity for the head looking downw^ards and forwards ; 

 closely siet with rather strong, rounded, setigerous granules, 

 the depressions between the granules forming, on the sides, a 

 foveate reticulum, most marked near coxae. Elytra (6 x 3"25 

 mm.) narrow, gradually widened from base to beyond middle, 

 greatest width not wider than prothorax ; apex strongly 

 rounded, flanged by a thickened margin on either side, with 

 a small but distinct median emargination ; base with four 

 tuberculiform projections extending anteriorly ; each elytron 

 with three rows of strong subconical tubercles above ; the rows 

 closely placed, the depressions of the striae hardly, if at all, 

 traceable ; the tubercles fairly closely set in the rows, their 

 apices obsoletely multipunctate ; the tubercles larger in the 

 more external rows, and in all the rows increasing in size 

 posteriorly; sides with three rows of depressed, closely set, 

 tubercles, the intervals more definitely puncto -striate. Beneath 

 with moderately large, round punctures on coxae, sterna, and 

 the two basal ventral segments, fewer and smaller on the 

 other segments; fifth segment not excavate. Legs moderately 

 long ; anterior coxae contiguous ; femora rather strongly 

 curved ; tibiae simple. Dim. — 10 x 3*25 mm. 



Hah. — Western Australia: Mount Barker (A. M. Lea), 

 ^Varren River (W. D. Dodd). Type in South Australian 

 Museum. 



I think the type is probably a male, but have not ventured 

 to dissect it to make certain. The specimen from Warren 

 River differs somewhat in having a transverse, scar-like impres- 

 sion near the basal third of the prothorax, apically to which 

 the projection of the median lobe suddenly rises. The elytra! 

 tubercles are of a much more pronounced red colour, and the 

 rostral punctures are somewhat coarser. I do not think it is 

 specifically distinct, as the scar of the prothorax appears to me 

 unnatural, and to some extent the insect is therefore a 

 monstrosity. If, howeyer, further specimens should be found 

 to bear this peculiarity in the prothorax, it will be necessary 

 to specifically separate it.
