The median vitta of the under-surface iiuich weaker, formed of 

 yellowish scales and short hairs. Only the three apical ventral 

 segments laterally impressed, the impressions almost continuous 

 and diverging a little in front, the apical segment rugulose in 

 middle and with a narrow transverse impression near extremity 



Anterior femora without a 

 apical projection of anterior 



between the lateral impressions, 

 ridge on lower side ; the inturned 

 tibioe lar-ger and more conspicuous. 



Length, 25 ; breadth, 8-25 mm. 



Habitat — Upper Murohison. 



This species seems most closely allied to S. vio/estus, Fasc, 

 among previously described species. My collection contains a 

 female specimen from some part of South Australia, which is 

 evidently *S'. moJcstiis, Pasc. ; compared with it, S. occidefitalis 

 is much less convex on both prothorax and elytra, has the 

 tubercles of the elytra red (not black), and much less conical and 

 strong on the apical half. It may also come near .S*. laticollis, 

 MacL, but, I think, from there being nothing to the contrary in 

 the description of »S'. laticollis, the tubercles must be placed in 

 that species equally in all the rows, as in S. Elderi, SI; besides 

 the present species seems too thickly covered witli scales for it to 

 be S. laticollis, of which Sir William Macleay says : — " The whole 

 insect is of an almost glossy black, and free from scales." 



The male is readily distinguished from the male of S. aw/usti- 

 pennis, SI, by its wide rostrum with the external ridges not 

 convex in profile ; the more convex prothorax with much larger 

 but less prominent granules, the sides of the prothorax apparently 

 more dilatate, with the middle projecting more sharply out from 

 the lateral parts above the coxie; the broader elytra more strongly 

 rounded on the sides, the shoulders forming a large blunt pro- 

 jection, not a tubercle, the apex widely rounded with the edge 

 thick and prominent on each side, the tubercles of the second and 

 fourth rows, &c., more numerous and more closely set. 



Among the Amycterides of the Elder Expedition there was only 

 a single female of this species. I am indelrted to the Re^'. 

 Thomas Blackburn for the loan of the male specimen described 

 above, which is in his collection as coming from West Australia. 



Selerorhinus angustipennis, n. sp. 

 Male. — Elongate, convex; prothorax dilatate, finely granulate ; 

 elytra narrow, with rows of red tuberculiform granules. Piceous- 

 black ; head, prothorax, and elytra covered with ferruginous 

 scales, these very close all over elytra (except where rubbed-ofi" 

 sides by femora), giving them a rusty appearance ; a narrow 

 median vitta of thick tawny hair extending on under-surface 

 from mesosternum to apex.
