176 THE ENTOMOLOGIST. 



testaceous, the head, thorax and legs sparsely covered with fuscous 

 pubescence ; wings hyaline, iridescent, slightly but distinctly tinged 

 with fuscous, the stigma and nervures black. <? . Length 3'5 mm. 



Kuching, Borneo (John Hewitt, B.A.). 



Head and pronotum covered with shallow, clearly separated 

 punctures, the latter more sparsely and weakly than the former and 

 having a distinct row of transverse punctures across the apex. 

 Basal half of mesonotum smooth and shining, the apical irregularly, 

 rather strongly aciculated ; there are no parapsidal furrows. Scu- 

 tellum smooth, its basal furrow wide, deep. Middle of metanotum 

 irregularly transversely striated ; there is in the centre a straight 

 keel extending to the apex ; there is a shorter one on either side of 

 it, about three-fourths of its length ; outside these, one which 

 roundly converges towards the apex, and which reaches to the apical 

 transverse keel ; the outer part of the metanotum is irregular, 

 striated to near the apex, which is entirely striated and with a stout 

 keel down the middle. Propleurse aciculated. On the lower basal 

 half of the niesopleurte is a curved furrow, its straight lower branch 

 divided by keels ; beyond this is a rounded, curved, crenulated 

 furrow, extending from near the tegulae to the low^er part of the 

 apex ; beyond this, on the upper half, is a shorter, wider, deeper 

 oblique furrow, without striae. The mesopleurge are weakly reticu- 

 lated, the vertical striae stronger than the longitudinal. The antennae 

 are stout, shortly densely pilose.

Chioncema subalba, sp. n. 



(? . Head and thorax white, the latter with three reddish bands, 

 the posterior one short ; abdomen whitish, tinged with reddish before 

 the white anal segment. Fore wings white with four reddish bands ; 

 the subbasal not extending to inner mai-gin ; the antemedial nearly 

 straight, but slightly turned inwards on the costa ; the postmedial 

 outwardly curved below the cell ; the submarginal curved and almost 

 parallel with the outer margin. The costal tuft with a black spot at 

 Its outer edge, and two black spots below it, the outer one linear. 

 Hind wings white sufi'used with pale reddish except on the costal 

 area ; a faint fuscous lunule at end of the cell. Fringes white. Under 

 side white, the costa of fore wings streaked with reddish from the 

 base to the sexual mark ; the reddish bands show but faintly ; the 

 lunule at end of cell of the hind wings is more distinct than on the 

 upper side. 



? . Similar but with three black spots ; the bands are rather
