Length 3^ lines. 

 Ilab. — Champion Bay, 



A small, rather narrow species, with comparatively- 

 slender posterior spines, and a prothorax without 

 tubercles. 



Section 3. 

 Elytra with six or eight dorsal spines.* 



35. Catasarcus concretus. 



Shortly ovate, very convex, black, rather closely co- 

 vered with fawn-coloured, mixed with white scales ; head 

 a little prominent in front but flattish above, a narrow 

 median groove below a slight depression beneath the eye, 

 but deeper and distinctly triangular below the transverse 

 sulcus ; prothorax small, rounded at the sides anteriorly, 

 transverse grooves nearly obsolete, a darkish stripe on 

 each side, a paler intermediate one; scutellum small, 

 triangular ; elytra seriate-punctate, the intervals here and 

 there tuberculate, post-humeral spine stoutly conical, 

 median and posterior spines rather short and stout, the 

 latter not much larger than the former, in a longitudinal 

 line with the median, and a little anterior to it, is another 

 short thick spine ; body beneath, with closely set scales ; 

 legs ferruginous, with the scales more dispersed and 

 mingled with numerous black setaceous hairs ; antennte 

 ferruginous, scaly, club dark brown. 



Length 4 lines. 



Hab. — Queensland. 



A short convex species, readily known by its addi- 

 tional pair of medilateral spines, and by the absence of 

 the basal spines ($,?), which all the following possess. 



36. Catasarcus trapa. 



Pitchy-brown, rather thinly covered with pale grayish 

 scales, but under the lens of a pale roseate hue ; head 

 nearly as in C. frihidns [pout, p. 40); prothorax about 

 a fourth broader than long, tolerably well rounded at 

 the sides, very rugosoly tuberculate ; scutellum small, 

 distinct, nearly equilaterally triangular; elytra rather 



* Perhaps this applies to the male sex only. Mr. Fry has a female 

 specimen, evidently belonging to one of the species of this section, which 

 is without the basal sj)ines.
