774 REVISION OP THE AMYCTERIDES, iv., 



tendency more marked on the sides; intrastrial granules distinct. 

 Interstices tuberculate; sutural costiform at base, elsewhere with 

 fine granules; second with seven, rather large tubercles, elongate 

 towards base, more raised and conical posteriorly, extending from 

 near base down declivity; third with a similar row of eight, from 

 base down on to declivity; fourth with no tubercles; fifth with a 

 continuous row of smaller tubercles, somewhat transverse, and 

 about thirteen in number; sixth with eleven, similar tubercles. 

 Sides with vertical rugas separated by depressions, not so marked 

 as in S. apicqlis. Dimensions: $, 15 x 6 mm. 



Hab. — Queensland. Type in Australian Museum. 



This species may be readily distinguished from the other mem- 

 bers of the group by the colour of the median, ventral vitta. The 

 tubercles on the fifth interstice are somewhat irregular ; in a speci- 

 men, in my own collection, they are almost absent on one elytron. 



I believe the type came from Queensland, but do not know from 

 what locality. There is a specimen, which I refer to this species, in 

 my own collection, from Tamworth, N.S.W. 



SCLERORINUS ATERRIMUS, Sp.n. 



^. Elongate, subparallel. Black, subnitid, legs diluted with red; 

 clothing practically absent; median, ventral vitta black; setae 

 black. 



Head separated from rostrum above by a slight constriction; 

 external rostral ridges continued back into forehead; median line 

 rather feebly subcarinate. Rostrum with external ridges slightly 

 convex in profile, somewhat sinuate as viewed from above ; median 

 carina strong, narrow, separated from head by a deep puncture; 

 sublateral sulci broad and deep, especially at base. Eyes ovate. 

 Prothorax (4x4-5 mm.) widest anteriorly to middle, subangu- 

 late at sides; ocular lobes not very prominent; disc with rather 

 large, rounded granules, variable in size, moderately closely set; 

 sides with granules obsolete. Elytra (10 x 5 mm.) elongate, sub- 

 parallel; base emarginate, humeri noduliform; with rows of small 

 punctures, each subtended by a small, setigerous granule, the 

 inner two rows regular, the outer rows confused and broken by the
