706 REVISION OF THE AMYCTERIDES, iv., 



The two following species I would also refer to *S. vittatus, 

 though with somewhat more doubt. 



S./uscus Macl. —The type is a male, and is .somewhat shorter 

 than iS'. vittatus, and uniformly clothed with dingy brown; the 

 tubercles are slightly smaller, round, not conical, forming a con- 

 tinuous row on the third interstice. 



S. confusus Macl. — The type is a partially abraded female, 

 with rather smaller tubercles than usual, set at intervals on the 

 third interstice. The setae are light-coloured. 



SCLERORINUS IRREGULARIS Macl. 



Macleay, loc. cit., p. 263. 



(J. Elongate-ovate; moderately large. Black; without clothing, 

 except a feeble macule in the centre of the third and fourth 

 ventral segments; setse yellowish. 



Head convex, flattened in front, running on into rostrum; 

 rostral ridges extending on to head. Rostrum wide; the ex- 

 ternal ridges slightly sinuate; median carina narrow, prominent; 

 sublateral sulci broad, shallow, with a deeper fovea at base; a 

 small puncture present in the middle line at junction of head 

 and rostrum. Prothorax (4 x 5 mm.) moderately dilatate, with 

 a well marked subapical impression; closely set with rather large 

 tubercles, elongate near middle, more rounded towards sides; 

 sides with granules obsolescent. Elytra(ll x 7 mm.) moderately 

 broad, gradually widened posteriorly; base gently emarginate, 

 humeral angle with a small rounded tubercle; seriate punctures 

 evident, small, open, each subtended by a small granule; inter- 

 stices tuberculate, tubercles small, rounded, conical posteriorly; 

 second interstice with five tubercles, extending on to declivity; 

 third with eight, at varying distances from base down on to 

 declivity; fourth with three or four about the middle; fifth with 

 a continuous row of seventeen to twenty, rather closely set, 

 rounded, rather smaller than on third interstice; sixth with a 

 continuous row of ten or eleven, outwardly and backwardly pro- 

 jecting. Apical ventral segment with a rather broad median 

 channel, bordered on each side by a small tubercle, the channel 

 somewhat transverse beyond the tubercles. Dimensions : $, 

 17 X 7 mm.
