irregular punctures. Abdomen flattened along middle, each 

 side of intercoxal process with an acute ridge terminating as 

 a subconical tubercle, fifth segment very short in middle, where 

 it is encroached upon by pygidium, fourth as long as second 

 and third combined. Basal joint of four front tarsi distinctly 

 inflated. Length, 4| mm. 



9 . ^^^^ Differs in having the abdomen strongly and evenly 

 convex, without ridges on basal segment, the fourth no longer 

 than third, hind tibiae somewhat shorter, and in the tarsi. 



Hah. — Queensland: Endeavour River (Macleay Museum), 

 Cairns (E. Allen). Type, I. 3492. 



The ridges on the basal segment of abdomen are curved, 

 with the convex side so placed that if the two were continued 

 they would at length form a circle or ellipse ; in this they differ 

 from the following species, where each ridge follows the line 

 of the coxa. 



Geloptera composita, n. sp. 



<S . Coppery-bronze, under-surface diluted with red ; 

 appendages flavous, knees and tips of four (or more) of apical 

 joints of antennae infuscated. 



Head with some small smooth spaces, and with dense 

 punctures, becoming smaller and denser at base and on 

 clypeus ; with a vague depression in middle. ProtJiorax and 

 elytra, much as in tuherculiventris. Basal segment of abdomen 

 depressed in middle, a curved ridge margining each hind coxa. 

 Four front tarsi with basal joint inflated. Length {<S , 9 )> 

 4-4| mm. 



9 . Differs in having abdomen more evenly convex, hind 

 tibiae shorter, and basal joint of four front tarsi smaller. 



Hah. — New South Wales: Sydney (Macleay Museum and 

 A. J. Coates), Galston (D. Dumbrell and A. M. Lea). Type, 

 I. 3493. 



In general appearance close to fubercidiventris, but 

 abdomen and hind tibiae very different. 



Geloptera scitula, n. sp. 



9 . Greenish-bronze, elevated parts with a vague cop- 

 pery gloss ; appendages testaceous or flavous, some parts 

 darker. 



Head with numerous punctures of moderate size, becoming 

 smaller and denser on clypeus and just behind same. Frofhorax 

 rather convex, sides gently undulated and scarcely dentate 

 about middle, sides with very dense punctures of moderate 

 size, becoming sparser about middle, and leaving two or three 

 small, almost impunctate spaces. Elytra with regular striae and
