This species seems to lead towards Perileptus, the head being 

 somewhat similar (the mandibles long and porrect), but with 

 very different frontal impressions. It ma}^ have some affinity to 

 the Chilian genus lliassalohms, which is unknown to me in 

 nature; but the head, though decidedly narrowed behind the 

 eyes, has the base wide and not forming a neck. Among Aus- 

 tralian species it can only be compared with Tachys murriiwhid- 

 (jHUsis, SI., and 2\ leai, SI.; but it differs conspicuously from these 

 species by head larger; eyes smaller, distant from buccal fissure 

 beneath; mandibles longer and more prominent, colour, kc. T. 

 ohliquiceps has the margin of the elytra hardl}", if at all, inter- 

 rupted posteriorly by an internal plica, though this feature is 

 tolerably well developed. 



Tachys setiger, n.sp. 



Oblong, depressed. Pale testaceous. Derm of head, prothorax 

 and elytra setigerous. 



Head convex, wide behind eyes; surface shagreened, setigero- 

 punctulate; frontal impressions shallow, short; e3'es small, round, 

 coarsely faceted, distant from buccal fissure beneath. Maxillary 

 palpi large; penultimate joint large, pyriform, pubescent, apical 

 joint very small and slender (merely a little spike); labial palpi 

 small, apical joint a short projecting spike. Mandibles short. 

 Prothorax depressed, lightly transverse, widest before middle, 

 narrowed to base; derm shagreened and sparsely setigero-punc- 

 tate; sides rounded on anterior part, strongly narrowed to apex, 

 lightly and obliquely narrowed to base; anterior angles obtuse, 

 very near head; posterior angles marked, rather obtuse; base 

 widely sublobate, cut obliquely on each side behind posterior 

 angles; basal area hardly defined, not below plane of disc in 

 middle, lateral border narrow, lateral basal impressions obso- 

 lescent. Elytra depressed, rather closely setigero-punctate over
