on an isolated specimen from Flinders Range; it agrees with 

 .S. regularis in the rounded character of the pro thoracic 

 granules, but differs in having the third interstice subcostate. 



SCLERORINUS ALBOVITTATTJS, n. Sp. 



<$ . Elongate-ovate, size moderate. Black; densely 

 clothed with yellowish-brown subpubescence ; head trivittate, 

 the median vitta subdivided by a median bare line, prothorax 

 trivittate with white, the median vitta narrow, elytra with 

 white vittse along the third and fifth interstices; sides of head, 

 prothorax, and lower border of elytra with white, the white 

 clothing more squamose in character; under-surface with 

 whitish macules on middle and sides of segments forming 

 interrupted vittae, last segment with white clothing distributed 

 over whole surface. 



Rostrum with median line bare, not definitely raised, 

 extending up on to and along forehead, basal foveas moder- 

 ately deep. Prothorax (4x5 mm.) transverse, moderately 

 ampliate on sides, ocular lobes rather feeble. Disc convex, 

 with transverse subapical impression and feebly impressed 

 median line, set with round somewhat-depressed setigerous 

 granules moderately close together, obsolescent along vittae; 

 sides granulate. Elytra (10 x 6 mm.) evenly rounded, not 

 greatly widened on sides, base gently arcuate, humeral angles 

 marked but not produced. Disc with punctures obscured by 

 clothing but apparently small and shallow; interstices tuber- 

 culate, the tubercles small, becoming somewhat larger pos- 

 teriorly, feebly conical on declivity; second with five or six 

 isolated tubercles, not extending down declivity, third inter- 

 stices tending to approximate on declivity, with a row of about 

 twelve from base nearly to apex, fourth with three anterior to 

 middle varying in position, fifth with three at humeral angle 

 only, sixth with a closely set row of twelve ; sides with regular 

 rows of rounded tubercles. Fifth ventral segment with small 

 median impression at extreme apex, bordered on either side 

 by a small tubercle obscured by clothing. Legs simple. 



9 . Similar to S but somewhat more ovate, and convex 

 beneath.

Though in general appearance close to species of the type 

 of S. germari, and, like that group, with the fifth interstice 

 only tuberculate at shoulder, the structure of the fifth ventral 

 segment points to a closer relationship to the adelaidce group, 

 though it is very distinct from any other described species of
