of the Genus Gatasarcus. 27 



closely scaly, the latter reddish-brown ; antennge ferru- 

 ginous-brown, the first joint of the funicle considerably 

 longer than the second, the remainder, to the sixth, 

 gradually shorter, the last longer and broader. 



Length 4^ lines. 



Hah. — Queensland. 



This species has a considerable resemblance to C. 

 griseus, but, inter alia, the larger punctuation of the 

 elytra affords a ready differentiation. 



Section 2. 

 Elytra with four dorsal spines. 



17. Gatasarcus intermedins. 



Rather shortly ovate, black, with a few scales chiefly 

 confined to the impressed portions ; head flat in front, but 

 with three well-marked carinas, the median the longest, 

 the others near the eye on each side ; prothorax rather 

 short, scarcely rounded at the sides, irregularly tubercu- 

 late, the posterior transverse groove nearly median ; scu- 

 tellum indeterminate ; elytra transversely grooved, the 

 intervals coarsely tuberculate with shallow longitudinal 

 impressions dividing them, post-humeral spine short, 

 obtuse, posterior pair of spines rather small, slightly 

 incurved, the median very small, conical, and more at 

 the side than in front of the posterior, both pairs placed 

 unusually far from the base ; body beneath, antennae, and 

 legs, dark ferruginous-brown, the last with rather longer 

 setaceous black hairs. 



Length 3^-4 lines. 



Hah. — Champion Bay. 



The transverse grooves on the elytra are only a modi- 

 fied form of punctuation, the punctures being broadly 

 impressed and uniting at the sides. This species, in the 

 smallness of its median and posterior spines, and their 

 remoteness from the base of the elytra, may be consi- 

 dered as forming a passage between the normal and the 

 spine-bearing members of the genus.
