Hah. — South Australia. Type in Australian Museum. 



Although I have described the type in some detail, I am by 

 no means certain that it is a valid species. The specimen 

 strongly suggests an abraded form of S. vittatus^ with the tuber- 

 cles on the third interstice situated at intervals. The lack of 

 clothing is so complete, that it is hard to believe the specimen 

 could have been artificially abraded. The light-coloured setae 

 are also a point of distinction. Unfortunately, I have not been 

 able to compare S. irregularis with S. co7ifusus, as the types are 

 in different collections. From my recollections of S. conjusus, 

 the type of S. irregularis appeared a rougher insect, with more 

 evident, intrastrial granules and somewhat larger tubercles. 



SCLERORINUS OBLONGATUS, n.sp.

 clothed with dark brown subpubescence; head and prothorax 

 trivittate with greyish, the median vitta divided into two on 

 the head and rostrum; elytra with a broad vitta along each side 

 of disc, subdivided by the fifth interstice, and with whitish 

 maculae forming a row along each side internal to the third inter- 

 stice; sides with scattered whitish subpubescence most marked 

 along lower border; undersurface with similar clothing at sides 

 of segments; legs with intermingled white and yellowish sub- 

 pubescence along upper and outer surfaces; setae dark. 



Head and rostrum very gently convex above in profile; fore- 

 head with a median, laevigate, subcarinate line. Rostrum little 

 excavate above ; external ridges parallel ; median carina pro- 

 minent, narrow; sublateral sulci broad, shallow, with deeper 

 basal fovae. Prothorax (4-5 x 5 mm.) moderately rounded on the 

 sides; apical margin gently sinuate above, with prominent ocular 

 lobes; disc with a moderately definite subapical impression, and 

 a longitudinal median impression; set with small, subobsolete, 

 flattened granules, for the most part elongate, more rounded at 

 the sides; sides with granules becoming obsolete towards the 

 coxae. Elytra (10 x 6 mm.) elongate, little widened posteriorly; 

 apex strongly rounded; base trisinuate-emarginate, the humeral 

 angles somewhat advanced, prominent, not tuberculiform; seriate
