A NEW GENUS OF AUSTRALIAN BEES. 141 



joints beyond the fourth with small oval whitish pits; long branched 

 hairs on abdomen beneath near end, and short plumose ones about 

 tubercles. Stigma and veins dark brown, well formed ; in the 

 following account of the wing the measurements are in microns (the 

 same also under the next species) ; stigma very large and deep, its 

 depth 153 ; marginal cell sharply pointed on costa, its length on 

 costa 357, its lower side beyond the submarginal cells slightly arched 

 inward ; first submarginal "long, its length 290 ; second submarginal 

 on marginal 85, its lower side absent ; upper section of basal nervure 

 34, lower (not allowing for the curve) 220 ; basal nervure from 

 transversomedial 60, the latter ol)lique, and bent at its lower end ; 

 first recurrent nervure joining first submarginal cell 12 from its end.

Heterapis sculpta, n. sp. 



? . Length about 4 mm. ; slender ; head and thorax black, 

 abdomen shining rufopiceous ; tubercles margined with yellow ; 

 mandibles ferruginous, dark at extreme base, feebly bidentate at 

 apex ; labrum dark ; scape in front and flagellum beneath pale 

 yellowish-ferruginous ; knees, anterior tibias, middle and hind tibia3 

 at base and apex, and all the tarsi, pale ferruginous ; wings hyaline, 

 very iridescent, nervures and stigma dark brown ; tegulae brown. 

 Clypeus and adjacent sides of face microscopically tessellate, with 

 large shallow punctures ; clypeus very long, separated from the 

 supraclypeal area by a slight depression, but no suture ; supraclypeal 

 area finely longitudinally striate ; a fine longitudinal keel between 

 antennce and reaching far up front ; ocelli large, middle ocellus 100 /x 

 diameter ; front very strongly punctured ; second antennal joint 

 oval, fourth and fifth very short ; flagellum stout, subclavate, the 

 penultimate joint 135 jx diameter ; mesothorax shining, strongly and 

 very regularly punctured ; abdomen beyond first segment finely 

 transversely lineolate ; metathorax microscopically reticulate. Claws 

 deeply bifid, pulvillus large ; anterior tarsi with hooked bristles ; 

 hair on under side of abdomen branched on one side. Stigma large, 

 only moderately deep, its depth 153 ; second submarginal and third 

 discoidal cells completely confluent ; upper section of basal nervure 

 102 ; lower section very strongly arched, falling 135 short of trans- 

 versomedial ; marginal cell 714 long, pointed on costa; first sub- 

 marginal 460 ; second submarginal above 93, its lower side absent. 



Compared with H. delicata, this is considerably larger ; the 

 head is differently shaped, being broad above, with the eyes 

 strongly converging below ; the metathorax is much less elon- 

 gated, and is rounded in lateral profile (angular in delicata) ; the 

 abdomen is broadest about the base of the second segment, 

 whereas in delicata it is broadest about the middle of the third.

Mr. Turner sends me several females of this species {Turner, 

 1085). The orange supraclypeal band is sometimes absent.
