384 REVISION OF THE AMYCTERIDES, ii., 



Lataurinus rugiceps Macleay. 



Talaurinus rugiceps Macl., loc. cit., p. 242. 



£. Large, elongate, subparallel. Black, subnitid, without 

 clothing; setae minute, black: undersurface and legs with longer, 

 denser, black setae. 



Head broad, granules strong, somewhat rugose. Rostrum 

 very short, rather broader than long; external ridges divergent 

 posteriorly; internal strongly convergent, meeting; the rest as in 

 the generic description. Prothorax (6x7 mm.) very broad, 

 widest behind apex, thence narrowed towards base; apical margin 

 with ocular and median lobes feebly but definitely marked; set 

 with round, rather coarse granules, sides granulate. Elytra 

 (12x7 mm.) not wider than prothorax, subparallel, base little 

 arcuate, humeri subrectangular, not produced; disc with rows of 

 small foveiform punctures, the inner two rows merged into one 

 in anterior half, posteriorly separated by a row of granules, but 

 communicating across, third and fourth, and fifth and sixth 

 similarly communicating across interstices ; interstices, first 

 (basally), third and fifth prominent, subcostate, becoming granu- 

 late on declivity; second (where present), fourth, sixth, seventh 

 and lateral interstices with rounded, closely set granules. Pro- 

 sternum with a small projection on each side in front of coxae. 

 Beneath, densely setigero-punctate; intermediates long, fifth with 

 a feeble ill-defined impression. Anterior femora not ridged. 



(J). Like male, but broader, especially the elytra ; humeral 

 angles projecting laterally; beneath, convex, prosternal projec- 

 tions obsolete. Dimensions : (£.21 x 7; £.14 x 8 mm. 



Hab. — West Australia: King George's Sound. Specimens 

 described, in the Macleay Museum, presumably the types. 



Not close to any species known to me, on account of its curious 

 rostrum. The antennae are comparatively short, the scape hardly 

 reaching the prothorax when lying back. 



Peritalaurinus, n.g. 



Large. Head short, very broad, strongly convex. Rostrum 

 separated from head by a transverse impression, short, wide, 

 little excavate, not dilatate on sides beyond the external ridges; a
