Hah. — Champion Bay. 



There is no appearance of scales on the upper surface 

 of this species, which is a very remarkable one, on 

 account of its smooth, somewhat varnished look, includ- 

 ing also the spines. 



22. Catasarcus nitidulus. 



Moderately ovate, black, vnth scattered grayish scales; 

 head flat in front, three tolerably well-marked grooves 

 above the transverse sulcus, bounded by four stout pro- 

 minent carinae, all covered, as well as the rostral grooves 

 and carinae, with yellowish-gray scales; prothorax short, 

 moderately transverse, well rounded at the sides, the 

 apex much narrower than the base, obtusely tuberculate 

 and partially glossy above, the sides and the two trans- 

 verse grooves scaly; scutellum larger than usual, very 

 distinct, triangular; elytra sulcate-punctate, the punc- 

 tures small, filled with scales, the intervals raised, and 

 forming close-set rows of glossy granuliform tubercles, 

 post-humeral spine black, the median and posterior 

 glossy brownish-red, the former scarcely a third so long 

 as the latter, sides along the outer margin densely scaly, 

 shoulders not broader than the base of the prothorax, 

 produced into a stout obtuse conical tubercle ; body be- 

 neath, black, partially scaly; legs brownish-red, with 

 much-scattered hair-like scales and sette; antennae red- 

 dish-ferruginous, finely scaly, with a few black setae,

Ilab. — Swan River. 



This species may be considered as most allied to 

 C. spinipennis, from which it will, however, be at once 

 distinguished by its carinate front. 



23. Catasarcus humerosus. 



Stoutly ovate, black, with thinly set dull grayish scales ; 

 head flattish in front, with four short moderately promi- 

 nent carina), covered as well as the rostrum with small 

 dispersed scales, among which are mixed long flattish 

 setae ; rostrum narrower than the front ; prothorax short.
