HYMENOPTERA OF SARAWAK. 121 



POMPILUXE. 

 Salt lis Bidleyi, sp. nov. 



Claws with 1 tooth. Black, the abdomen with purple re- 

 flections ; the 2nd and following joints of the hind tarsi, except 

 at the apex, testaceous ; wings blackish ; fuscous-hyaline, slight- 

 ly tinged with yellow, between the transverse median and the 

 transverse basal and the 2nd transverse cubital and the 2nd 

 recurrent nervures ; the hind wings blackish at the base, the 

 rest fuscous hyaline, tinged with yellow. 6 . 



Length 21 mm. 



Matang. 



Front and vertex sparsely, the outer orbits densely covered 

 with long black hair; the lower two-thirds of the inner orbits 

 lined with obscure testaceous. Clypeus minutely shagreened, 

 and with some scattered punctures ; bare, the apex broadly 

 rounded. Labrum large, shagreened ; its apex rounded. Palpi 

 black, bare, the apical joints covered with a pale pile. Thorax 

 velvety, the prothorax and the median segment covered with 

 long black hair ; the sides of pronotum broadly rounded, not pro- 

 jecting. Post-scutellum prominent, clearly separated, tubercu- 

 late, the base with a straight oblique slope ; its apical slope is 

 shorter and steeper. The striation on the metanotum is 

 coarse; the lateral tubercles are very prominent. Meta- 

 pleurae finely, closely, obliquely striated. Tibiae sparsely, the 

 tarsi more thickly spinose ; the spines short ; the long spur of 

 the hind tibiae is thickly covered with black hair at the base ; 

 it is about one third of the length of the metatarsus — as long 

 as the 2nd joint. The 2nd transverse median nervure is 

 dilated in the middle, where the recurrent leaves it, the latter 

 being also dilated (but not so strongly) at the base ; in the hind 

 wings the transverse anal nervure is received beyond the cubital. 



Comes near to S. fulgidipcnnis Sans, and S. iridipennis 

 Smith. The colour otthe middle joints of the hind tarsi may 

 be clear yellow, as it is on the 2nd joint of one leg, i.e. the tes- 

 taceous colour of the other joints may be owing to discolour- 

 ation. The coloured tarsal joints and the testaceous (yellow?) 

 line on the inner orbits are probably characteristic/.
