Geloptera illidgei, n. sp. 



cS . Bright metallic-green, with a golden gloss, parts of 

 under-surface brassy ; labrum and appendages flavous, but tips 

 of antennae and of palpi infuscated. 



Head with very dense (and in places confluent) punctures 

 of rather small size, . a small impunctate elevation near each 

 antenna. Frofho?'ax scarcely twice as wide as the median 

 length, each side with a small median tooth ; with dense, deep, 

 and fairly-large punctures, more crowded on sides than on 

 disc, with much smaller punctures scattered about. Elytra 

 with dense and fairly large punctures, transversely confluent 

 with conspicuous transverse ridges over most of the surface ; 

 striae present only on parts of apical slope. Basal segment 

 of abdomen depressed in middle, fifth transversely impressed 

 and encroached upon by pygidium. Front fe?nora lightly 

 dentate, the hind ones widely but obtusely dentate ; four front 

 tarsi with basal joint greatly inflated. Length, 5J-6 mm. 



Hab. — Queensland: Brisbane (R. Illidge). Type, 



I. 3502. 



This and the following species are certainly closely con- 

 generic with Edusa singnlaris (synonymous with Colaspis 

 jiif/ularis), but I refer them all to Geloptera, on account of 

 the conspicuously dentate sides of prothorax ; the two have 

 some short and sparse golden pubescence about apex of elytra ; 

 it could easily be overlooked, but from certain directions is 

 fairly distinct. The hind femora appear to be largely angu- 

 late, with the summit of the angular portion truncated. A 

 second specimen differs from the type in being of a greenish- 

 bronze colour. 



There are two specimens of this species in the British 

 Museum from Moreton Bay ; one is of a bluish-green, the 

 other is coloured as the type. 



Geloptera lateridens, n. 6p. 



d . Bright metallic-green ; labrum and appendages 

 flavous, under-surface somewhat darker. 



Head with rather small, crowded punctures; becoming 

 smaller and denser on clypeus, and smaller and sparser 

 towards base; a smooth impunctate space near each antenna. 

 Prothorax not twice as wide as median length, each side con- 

 spicuously bidentate about middle ; with dense and rather 

 large punctures on sides, becoming sparser about middle. 

 Elytra with dense and rather coarse punctures, in places 

 transversely confluent ; striation distinct only on apical slope 

 near suture. Abdomen gently convex, fifth segment 

 depressed in middle and encroached upon by pygidium. 

 Front femora strongly and acutely dentate; basal joint . of 

 four front tarsi somewhat inflated. Length, 5 mm.
