Geloptera tibialis, n. sp. 

 PL viii., figs. 125 and 126. 



(S . Bronzy; appendages testaceous, in places infuscated. 



Head with crowded punctures of moderate size, becoming 

 smaller and denser on clypeus. Eyes rather widely notched. 

 Prothorax somewhat uneven, each side with a conspicuous 

 median tooth ; with dense and fairly coarse punctures, almost 

 or quite absent from three feebly-elevated submedian spaces. 

 Elytra uneven ; with dense and coarse punctures ; striae and 

 interstices well defined on apical slope. Basal segment of 

 abdomen with a conspicuous conical tubercle in middle of apex, 

 fourth depressed in middle of apex, and in middle before same 

 with a feeble tubercle, sides encroaching on fifth, fifth with a 

 wide median fovea. Yront femora lightly but acutely dentate ; 

 hind tibiae with a wide, thin, and somewhat curved apical 

 flange, wider than the following joint and about the same 

 length; basal joint of four front tarsi inflated. Length, 

 4|-5 mm. 



9 . Differs in having the abdomen evenly convex and 

 simple, hind tibiae without the apical flange, and in the basal 

 joint of four front tarsi being smaller. 



Hah. — Northern Queensland (Blackburn's collection and 

 H. J. Carter) : Coen River (H. Hacker and W. D. Dodd), 

 Cairns (E. Allen and A. M. Lea). Type, I. 3500. 



Readily distinguishable from all other species by the 

 abdomen and hind tibiae of the male ; the former, owing to the 

 pygidium, appears to be composed of six segments. The under- 

 surface has usually a greenish gloss, but in places is obscurely 

 diluted with red. From five to eight of the apical joints of 

 antennae, the hind knees (or all of them), middle of tibiae, 

 and three basal joints of tarsi, are more or less deeply infus- 

 cated. On many specimens there are some small impunctate 

 spaces on the head, but they are frequently absent; on the 

 elytra, as well as on the prothorax, several small spaces, owing 

 to absence of coarse punctures, appear lilie feebly-elevated 

 tubercles. 



Geloptera concinna, n. sp. 



d* . Golden-red ; under-surface bronzy-green, becoming 

 brassy in places, labrum and appendages flavous. 



Head with crowded punctures of moderate size, somewhat 

 smaller on front of clypeus than elsewhere, and in places 

 longitudinally confluent. Prothorax rather strongly convex, 

 sides feebly undulated ; punctures as dense as on head, but 

 somewhat larger. Elytra with punctures of almost even size 

 throughout, but somewhat larger than on prothorax, and
