elytra are without defined lines ol" flothing', and are more coarsely sculptured ; 

 structurally it is close to E. iiiekmoptera, but is conspicuously metallic, and the 

 elytral clothing- is decidedly longer. 



GELOPTERA ARMIVENTRIS Lea. 



Two females, from Thursdai Island, appear to belong to this species: they 

 differ from the male in having someAvhat shorter legs, hind tibiae without pro- 

 duced apical spur, and abdomen more convex and simple. 



GELOPTERA APICILATA sp. nov. 



S Piceous-brown with a bronzy gloss, parts of under-surface paler; labrum, 

 legs (knees and claws infuscated), basal third of antennae and palpi flavous. 



Head with fairly dense and sharply defined punctures. Byes rather large 

 and prominent. Prothorax about twice as wide as long, sides almost evenly 

 rounded, angles unarmed; punctures much as on head, but somewhat larger near 

 hind angles than elsewhere. Elytra with dense and fairly coarse punctures, 

 becoming confined to striae posteriorly, interspaces witb minute punctures. 

 Abdomen finely transversely strigose and with numerous suljasperate punctures; 

 fifth segment with a small, transverse, median fovea. Femora stout and edentate; 

 hind tibiae with apical third dilated and l)ent outwards ; basal joint of front and 

 of middle tarsi dilated. Length, 5 mm. 



Hah. North-western Australia: Wyndham (J. Clark from W. Crawshaw). 

 Type, I. 11999. 



In size and general appearance very close to G. tuherciUiventris, but hind 

 tibiae very different, abdomen not tuberculate and sides of protHorax different ; 

 it is still closer to G. rhaehocnenm, l)ut the hind til)iae are shorter and somewhat 

 wider at apex, with the whole of the dilated part bent outwards, and the basal 

 two-thirds distinctly thinner, the fourth segment of the abdomen is slightly 

 smaller (slightly shorter than the second and third combined) and not trans- 

 versely depressed, the fifth has the lateral depressions less pronounced, and the 

 median fovea more abrupt; the punctures of the upper-surface are also somewhat 

 smaller and sparser. The type has three small, slightly elevated, impunctate 

 spaces on the front of the head, but a second specimen is without such. 



GELOPTERA VIRIDIMARGINATA sp. nov. 



$ Black with a coppery or bronzy gloss, margins of prothorax and of elytra, 

 and parts of under-surface dark green ; labrum, tip of abdomen, and parts of 

 legs obscurely flavous, or testaceous. 



Head with dense, sharply defined punctures. Eyes large and prominent.
