GELOPTERA APICIVENTRIS sp. nov. 



i Bright, metallic bluish-green, in parts w\\\\ a faint co))pery gloss ; labrum, 

 most of antennae, and parts of palpi and of legs more or less reddish. 



Head with fairly dense and sharply defined punctures, a vague depression 

 in middle; a small, highly polished, coppery spot near each antenna. Eyes 

 large and rather widely separated. Antennae rather long and thin. Prothorax 

 not twice as wide as the median leng-th, sides almost evenly rounded, hind angles 

 only armed ; with rathei- large, sharply defined punctures somewhat irregular in 

 middle, croAvded on sides. Elytra with crowded and rather large punctures, a 

 few transversely confluent before middle, posteriorly near suture confined to 

 striae. Abdome]i with basal segment depressed in middle, margins of intercoxal 

 process narrowly elevated, fourth segment large, a wide de]iression on each side 

 of middle, fifth segment foveate and red in middle, with a distinet central granule. 

 Femora stout, front ones rather minutely dentate; hind tibiae elongate, apical 

 fourth dilated. Length, 5-5-25 mm. 



Ilcib. Northern Territory : Darwni. Type, 1. llilTO. 



In general appearance close to G. intercoxalis, but legs darker, front femora 

 dentate, abdomen with the ridge on each side of intercoxal process not passing the 

 coxa, and two apical segments different. 



ALITTUS CARINATUS Blackb. 



On the type and on several other specimens of this s]iecies, the elytra are 

 uniformly coloured, except that on some parts the green sheen is more con- 

 spicuous than on others; but on three Darwin specimens there are three 

 conspicuous pale lines on each elytron, the punctures between the first and second 

 lines are in four ii-regular rows; on three others the pale lines are present, but 

 more feebly defined. 



ALITTUS FLAVOLINEATUS sp. nov. 



$ Reddish-castaneous, in parts with a coy)pery, or bluish, or purplish gloss; 

 aniennae, .palpi, and three distind lines on each elytron Havous. Head, pro- 

 thorax, undei'-surface and legs with depressed, white ])nbes('('nce, tij)s of elytra
