762 kEVlSlO?^ OF THE AMYCTERIDES, IV., 



Hah. — South Australia. Type in Australian Museum. 



I cannot separate *S'. arenosus from this species; under the 

 name-label of .S'. arenosus in the Australian Museum, are two 

 females, certainly conspecific, one of which has dark set{«, and 

 the other light. In all respects, these agree with the type-female 

 of *S'. sahulosus. 



S. Dixoni Ferg., and S. Goudiei Ferg., are very closely allied, 

 but I think worthy of separate names. The points of distinction 

 between them were fully discussed when they were described. 



SCLERORINUS MOLESTUS PaSC. 



Pascoe, Journ. Linn. Soc, xii., 1873, p. 9. 



$. Elongate, subparallel, large. Black, elytral tubercles diluted 

 with red; densely clothed with silaceous squames, except on 

 tubercles; median ventral vitta reddish-brown. 



Head convex, continued on into rostrum, sometimes a slight 

 transverse impression at junction; external rostral ridges con- 

 tinued on up the head. Rostrum shallowly excavate; external 

 ridges prominent, thick, parallel; median carina narrow, little 

 raised, not continued up forehead; sublateral sulci rather narrow, 

 Avith a deeper depression at base. Eyes subovate. Prothorax 

 (8x8-5 mm.) widely dilatate; apical margin rounded above, with 

 moderately distinct ocular lobes; subapical transverse impression 

 moderately strongly marked; median and sublateral impressions 

 feeble or absent; closely set with small, round, slightly depressed 

 granules, rather smaller in the centre. Sides with very small, 

 distant granules, absent on posterior portion. Elytra (16x8-5 

 mm.) elongate, subparallel, very little widened posteriorly; base 

 widely emarginate, humeri noduliform; punctures shallow, ob- 

 scured by clothing, the intrastrial granules small, inconspicuous; 

 sutural interstice with a row of fine granules, thickened towards 

 the base, hardly traceable apically; second with a few small, 

 slightly depressed, granuliform tubercles, not reaching base nor 

 extending down declivity; third interstices approximated on de- 

 clivity, each with a continuous row of small tubercles, closely set, 

 rounded and slightly depressed towards base, slightly more pro-
