Hah. — North-w&stern Australia. Type (unique) in 

 Macleay Museum. 



Of the general appearance of tuherctdiventris and vncinata, 

 but abdomen and apex of hind tibiae very different. From 

 some directions the elytra appear to be uniformly bronzy, but 

 from others the depressed parts appear to be dark metallic- 

 green, and the elevated parts (the feebly-elevated interstices 

 between the subgeminate rows) brassy. 



Geloptera bidentimedia, n. sp. 

 PL vii., fig. 75. 



(S . Of a greenish-bronze, elytra and under-surface some- 

 what paler; labrum and appendages flavous, but knees and 

 five apical joints of antennae infuscated. 



Head with dense, and not very large, but sharply-defined 

 punctures, larger between eyes and smaller in front of clypeus 

 than elsewhere. Prothorax with two conspicuous teeth on 

 each side about middle ; punctures slighter larger but other- 

 wise as on preceding species. Elytra with somewhat denser and 

 larger punctures than on preceding species, but otherwise 

 much the same. Flanks of ijrostenuini with punctures as on 

 adjacent portion of pronotum. Fourth segment of ahdo7nen 

 gently convex, almost as long as second and third combined, 

 fifth transversely foveate in middle of apex. Femora stout, 

 edentate ; hind tibiae rather elongate, gently dilated to apex, 

 which is scarcely wider than that of middle pair; basal joint 

 of four front tarsi somewhat inflated. 



Hah. — Queensland: Endeavour River. Type (unique) 

 in Macleay Museum. 



In general appearance like the preceding species and 

 composita, but sides of prothorax conspicuously bidentate in 

 middle. 



Geloptera porosa, n. sp. 



d . Of a livid-brown with a bronzy-green gloss ; appen- 

 dages somewhat paler, knees (frequently only the hind ones) 

 and tip of antennae infuscated. 



Head with dense punctures of moderate size, becoming 

 smaller and more crowded on clypeus; eyes smaller but more 

 prominent than usual and rather conspicuously notched. 

 Prothorax evenly and rather strongly convex, each side with 

 an acute median tooth ; with dense, rather large and deep 

 punctures, rather more crowded on sides than on disc. Elytra 

 with dense punctures, somewhat larger than on prothorax. 

 Ahdomen widely flattened but somewhat uneven along middle. 

 Basal joint of four front tarsi strongl}'- inflated. Length, 

 4-6 mm.
