others somewhat irregular, hardly rugulose, non-granulate, with 

 a few setae. Anterior femora ridged beneath. Middle tibiae 

 simple. 



Dim. — rf ., 24x8 mm. 



flab. — Northern Territory; South Australia: Cleve 

 (Blackburn). 



Type in South Australian Museum. 



Two specimens, both males, from the late Rev. T. Black- 

 burn's collection, in memory of whom I have named it. I 

 regard it as probably the finest species yet described in this 

 genus. It is most nearly related to S. biordinatus , but differs 

 decidedly in clothing, and in the much larger tubercles both 

 on thorax and elytra ; the strong dark tubercles contrasted 

 against the rich almost reddish-brown clothing should render 

 it easy of identification. Although the type is labelled 

 Northern Territory, it seems improbable to me that this species 

 should range from Cleve in Yorke Peninsula, South Australia, 

 to the Northern Territory, particularly as the other members^ 

 of the genus are almost all restricted in their habitat. Fur- 

 thermore, the only other species of Sclerorinus in the present 

 collection labelled as coming from Northern Australia are 

 species whose known habitats are in the south of South Aus- 

 tralia. The possibility suggests itself, therefore, that all these 

 species have through some error been wrongly labelled. 



Sclerorinus alpicola, n. sp. or var. 



<$ . General fades that of S. inconstans, Lea, but slightly 

 smaller and somewhat narrower. Black, legs sometimes 

 diluted with red; clothing much as in S. inconstans, but 

 rather lighter, brownish with whitish vittae, head trivittate, 

 median vitta subdivided into two, prothorax trivittate, elytra 

 with rather feeble vittae traceable along the two inner and 

 two outer striae ; with median black hirsute vitta along under- 

 surface. 



Head with external rostral ridges continued for some dis- 

 tance along each side of forehead, median rostral carina dis- 

 tinctly elevated, continued on to head but interrupted at 

 junction of head and rostrum, sublateral foveae moderately 

 deep. Prothorax (4 x 4"5 mm.) widest anterior to middle,, 

 ocular lobes rather feeble; set with fine scattered granules, 

 larger in apical third, generally smaller than in S. inconstans. 

 Elytra (10x6 mm.) less dilatate than in S. inconstans, rows 

 of punctures similar but tubercles on interstices smaller and 

 fewer in number; second with two or three, third with five or 

 six unevenly spaced over whole length of interstice, fourth 

 without any, fifth variable in number and position of the 

 tubercles, these not forming a closely-set row but spaced out
