different, but, in this respect, both species show considerable 

 variation. The clothing on the rostrum, however, appears to be 

 constant; in S. pilularius'ii is yellow, contrasting with the almost 

 snowy-white clothing of S. suhlineatus. S. pilularius appears to 

 replace S. sublineatus in the western portions of South Australia. 

 I am uncertain whether the types are in the Australian or in the 

 Macleay Museum. 



ScLERORiNUS EXiLis Macleay. 



Macleay, loc. cit., p. 245; S. angustatus Macl., Z.c, p. 246. 



Elongate, elliptical. Black, tubercles reddish; densely clothed 

 with dark brown; head, prothorax, and elytra conspicuously tri- 

 vittate with white, the median vitta bifurcated on the rostrum; 

 sides of prothorax and elytra vittate with white along lower 

 border; undersurface with scattered, yellow pubescence, and with 

 a strong, median, golden, hirsute vitta. 



Head convex, forehead very slightly depressed in front, not 

 carinate. Rostrum moderately short; external ridges subpar- 

 allel, somewhat out-turned at base; median carina narrow, little 

 elevated; sublateral sulci broad, shallow, deeper at base. Pro- 

 thorax (5x6 mm.) moderately strongly rounded on the sides, 

 apical margin gently rounded above, with moderately prominent, 

 ocular lobes ; subapical impression distinct ; median line not 

 impressed ; set with small, but rather conspicuous, distinctly 

 separated granules; sides not granulate, except above. Elytra 

 (14 X 7 mm.) subelliptical; base gently emarginate, humeral angles 

 distinct, set with a small tubercle; seriate punctures moderately 

 distinct, each subtended by a small, setigerous granule; interstices 

 with isolated tubercles, rounded near base, becoming conical pos- 

 teriorly; suture with a row of fine granules, larger at base; second 

 with a comparatively few, isolated tubercles, from near base to 

 edge of declivity; third with more numerous tubercles, extending 

 from base to apex; fourth with a few tubercles near middle; fifth 

 with isolated tubercles extending from humeral angle to edge of 

 declivity, sixth with tubercles more closely set with outwardly- 

 projecting, conical tubercles, not reaching to base. Sides with
