Hah. — Western Australia. 



A broad handsome species, varying considerably in 

 size; the elytra covered with numerous fine tubercles, 

 amongst which the shallow punctures filled with pale 

 lemon or grayish scales are very marked, notwithstand- 

 ing that the punctures themselves, in rubbed specimens, 

 are very indefinite. 



4. Catasarcus longicornis . 



Oblong ovate, moderately convex, glossy black, with 

 grayish scales limited to the impressed parts ; head with 

 a vertical prominence in front, divided below into two 

 carinse, the outer carina on each side, as well as those 

 on the rostrum, well-marked ; the grooves, except the 

 median one on the front, filled with scales; prothorax 

 rather long, well rounded at the sides, and slightly con- 

 tracted at the base, which is, however, much broader 

 than the apex, rather finely and somewhat transversely 

 corrugate above; scutellum very distinct; elytra closely 

 striato-punctate, the punctures large, mostly much 

 broader than long, filled with grayish-white scales, the 

 intervals forming narrow glossy transverse ridges, post- 

 humeral tubercle obsolete; body beneath black, rather 

 closely covered with oblong grayish scales, but darker 

 on the last three segments; logs reddish-ferruginous, 

 glossy, with few scales, the knees and tarsi blackish; 

 antennae slender, glossy ferruginous, more or less covered 

 with minute whitish scales, funicle with all the joints 

 elongate, but so far as the penultimate gradually shorter, 

 club rather short, dark brown, pubescent. 



Length 5-5.2 lines. 



Hah. — Champion Bay. 



This species bears a close resemblance to C. Hopii, but 

 it is much more elongate, the prothorax considerably 

 longer in proportion, much more rugose, and, above all, 

 the antenna) are difierently modified ; in C. ITopii the funi- 

 cle is short, with the last five joints not much longer than 

 broad, although a very gradual sliortening may be traced 

 to the last, and the third joint scarcely half as long as 

 the second ; while in this species, all the joints from 

 the third inclusive, ai-o nearly twice as long as the cor- 

 responding ones in C. Ilopii.
