The elytra are those of quite a typical Acantholophus; the 

 conical tubercles are on the third, fifth, and seventh inter- 

 stices ; those on the third commence on the base and termin- 

 ate just below summit of posterior declivity, those on the 

 fifth commence at the base and terminate at the declivity, 

 and those on the seventh commence near the shoulder and 

 terminate before the middle. 



The Macleay Museum specimen is from Stirling Range 

 (the locality given in Masters' Catalogue), but the type 

 was recorded from King George Sound. 



CuBICORRHYNCHUS STERILIS, PaSC. 



The description of this species is utterly worthless, being 

 little more than a brief comparison with morosus, a name 

 which is probably applied to many different species in col- 

 lections. In morosus and the allied species (taurus, Mussoni, 

 dilatieeps, Blackb. ; piceosetosus, maculatus, calearatus, Mad. ; 

 occult us and mpdestus, Sloane) T believe it to be impossible to 

 conclusively identify most of the species from the descrip- 

 tions already published, and, further, that it is almost impos- 

 sible to describe the females of most of them so that they can 

 be conclusively identified. They all have an oblique, obtuse, 

 granulated ridge on each side of the base of the prothorax, 

 and in the middle of the base itself two granules rather more 

 conspicuous than those elsewhere. 



Most of the species, however, may be quite readily iden- 

 tified by the tibiae of the male, and especially the hind pair ; 

 and these are not even mentioned in the description of 

 iterilis. But as the type should be in the British Museum, 

 some hope may be entertained of having the tibiae described 

 eventually. (5 ^ 



CUBICORRHYNCHUS PICEOSETOSUS, Mad. 



The types of this species are both females. Their setae 

 are darker and shorter (on the apical half of the elytra, 

 however, they are much as in many other species of the 

 genus) than in any other specimens I have seen, and this is 

 possibly characteristic of the species. Structurally I cannot 

 distinguish them from the types of maculatus, but possibly 

 an examination of males of both forms would confirm them as 

 distinct. 



(5) Mr. C. J. Gahan writes me that the type of this species "is 

 evidently a female ; the hind tibia? are straight, not granulated, 

 covered with pale scales, with seta? interspersed."
