HYMENOPTERA FROM SARAWAK. 63 



broad; the legs are long 1 ; the claws longish; the hinder cpxse are 

 long and reach near to the apex of the petiole ; the spiracles on the 

 petiole are separated from each other by about half the distance 

 they are from the apex; the scutellum is stoutly keeled laterally 

 to near the middle, the parapsidal furrows extend to shortly 

 beyond the middle. The 5 is similar to the Q ; the antenme 

 are longer and more slender, they are broadly ringed with 

 white in both sexes; the apical abdominal segments in both 

 sexes are marked with white. 



The species of the genus are very similarly coloured to 

 Buodias with Which genus it agrees in some other respects ; the 

 difference in the form of the median segment enables them to be 

 separated ; in Bnodius it is shorter, is stoutly spiued, and the 

 apex has a straight oblique, not a gradually rounded slope ; in 

 Buodius, too, the recurrent nervure is received at the apex of 

 the areolet, almost united to the second transverse cubital 

 nervure. Also the median segment is not transversely striated. 



Lactoltis albomaculatus, sp. nov. 



Niger, annulo flagello antennarum tarsisque posticis albis; coxis 

 posticis rufis alis fumato-hyalinis, nervis stigmatique nigris £ . 



Long. 13; terebra 3 mm. 



Hab. Sarawak, Borneo (Shelford). 



Antennae longer than the body ; the sixth to twelfth joints, 

 for the greater part, white. Face rugosely striated in the 

 middle ; at the sides the striae are oblique and more distinctly 

 separated. Clypeus stoutly keeled in the middle; the rest 

 aciculated and irregularly and not very strongly striated. The 

 base of the mandibles closely striated ; the teeth are for the 

 greater part rufous. The front and the vertex from the hinder 

 ocelli stoutly striated. Thorax shining ; the pro-mesonotum and 

 the base of the median segment smooth, striated. The meso- 

 pleural furrow is wide and deep ; its lower part is stoutly 

 striated. Legs black ; the apical half of the metatarsus, the 

 second and the fourth joints except at the apex, white ; all the 

 coxae and the four front trochanters bright red ; the anterior 

 tibiae and, to a less extent, the femora are brownish. Wings 

 hyaline, with a slight, but distinct, smoky tinge ; the stigma 

 and nervures are black ; the second transverse cubital nervure
