196 THE INSECTS OF GAYNDAH, 



891. — Heteronyx concolor. b. sp. 

 Length 2| lines. 

 Flat, brownish red, subnitid, punctate and finely pubescent. 

 Clypeus slightly emarginate with the apex of the labrum broad 

 and appearing in front. Thorax finely, elytra roughly punctate. 

 Body beneath very sparingly pilose. 



392. — Heteronyx ruficollis. n. sp. 



Length 2^ lines. 

 Elongate, punctate, pubescent, subopaque, and black, with 

 the head thorax and legs red. Clypeus slightly emarginate with 

 the apex of the labrum broad and visible in front. Thorax 

 rounded at the base and posterior angles. Elytra subtruncate 

 and obsoletely striated. 



393. — Hetekonvx rugosipennis. n. sp. 



Length 6 lines. 

 Reddish chesnut, nitid, thinly punctate, and clothed with 

 erect fulvous pile. Clypeus rounded, reflexed and entire. Tho- 

 rax almost truncate at the base, and with a brown nodule near 

 each side. Scutellum densely punctate except at the extremity. 

 Elytra coarsely punctate and transversely rugose. Pygidium 

 and under side of body thinly punctate — the punctures large and 

 each furnished with a long erect hair. 



I have some doubts about this being a Heteronyx at all. The 

 labrum is very short, almost truncate, and scarcely turned up at 

 the apex. 



Odontotonyx. n. gen. 



Antennae of nine joints, 1st long, clavate ; 2nd globular ; 3rd, 

 4th, 5th, and 6th very small ; the other three forming a club with 

 the lamince short. Labrum short, narrow, horizontal, lightly 

 emarginate, and completely covered by the clypeus. Mentum 

 apparently rounded at the apex. Palpi with the terminal joint 

 longest. Elytra not entirely covering the pygidium. Fore tibiae
