;apex, eleventh about one-third longer than tenth. Pro- 

 thorax distinctly longer than wide, base not much wider than 

 apex, sides feebly dilated slightly nearer base than apex, 

 with dense corrugations, somewhat irregular, across middle. 

 Elytra slightly wider than prothorax, sides feebly decreasing 

 in width to middle, thence parallel-sided to apex, where each 

 is semi-circularly notched and rather acutely bispinose. Legs 

 very thin, tibiae somewhat curved. Length, 11 mm. 



Hah. — Western Australia (W. du Boulay). Type 

 (unique), I. 5703. 



The type is the smallest specimen of the genus I have 

 seen. From the preceding species it is distinguished (apart 

 from size) by the very different clothing (the antennae, how- 

 ever, are very similarly fringed), prothorax wider in front, 

 with the sides more rounded, more conspicuously multi-cor- 

 rugate, and by the outer spine of each elytron smaller than 

 the inner one. The clothing is moderately dense between the 

 eyes, about the middle on each side of elytra, and on each 

 side from apex of prosternum to apex of metasternum ; on 

 the base of elytra, about the middle, it is not quite so dense 

 as on part of the sides, but rather denser than on the adjacent 

 parts; the disc of the pronotum is non-vittate. The femora 

 are without sexual adornment. The false suture of the 

 ■^eleventh joint of antennae is very distinct. 



Uracanthus tropicus, n. sp. 

 PI. xxxii., fig. 13. 



Piceo-castaneous, some parts paler. Rather densely 

 clothed with stramineous pubescence, becoming whitish on 

 antennae, under-surface, and legs. 



Head with median line deep ; clypeus equilaterally 

 triangular, punctures rather small, suture deep. Antennae 

 extending to about fourth segment of abdomen, fourth to 

 tenth joints feebly produced on one side at apex, eleventh 

 very little longer than tenth. Prothorax about twice as long 

 as the apical width, which is but little less than that of the 

 base, sides moderately rounded in middle; middle of disc 

 smooth and. with a few small punctures, base, apex, and sides 

 irregularly corrugated. Elytra not much wider than pro- 

 thorax at base, very feebly diminishing in width to apex, 

 where each is strongly emarginate and acutely bispinose ; with 

 small punctures and some large (but not very large) ones 

 towards base ; with remnants of vaguely elevated lines. 

 Length, 15-16 mm.
