96 HYMENOPTERA FROM SARAWAK. 



the stride are more widely separated in the centre ; the second 

 keel does not reach to the apex. The apical slope is thickly 

 covered with white hair ; the striation is close and obliquely 

 transverse; the upper lateral teeth are small. The mesopleurae 

 are distinctly, but not closely, punctured ; the upper part of the 

 metapleurae is stoutly striated. Legs for the greater part blue ; 

 the femora more greenish in tint than the tibiae ; the inner tooth 

 of the claw is shorter and stouter than the outer. Wings 

 hyaline, the radial cellule, the space bounded by the first and 

 third transverse cubital nervures and the upper part of the dis- 

 coidal are smoky ; the three transverse cubital nervures are 

 distinct. Abdomen largely marked with blue and purple tints ; 

 the third segment is largely marked with rosy and brassy 

 tints; it is strongly punctured; its apical half is distinctly depres- 

 sed, is more fiery in tint than the base and is more closely and 

 not so strongly, punctured. 



Comes near to A. sodalicia, Kohl, from Malacca. 



Tuchytes borneana, sp. nov. 



Black ; the head and thorax densely covered with pale sil- 

 very pubescence ; the abdominal segments banded with silvery 

 pile; the pygidium covered with golden pubescence; wings 

 hyaline, with a faint yellowish tinge ; the nervures pale testa- 

 ceous ; the second and third cubital cellules at the top equal 

 in length 9 . 



Long : 13 mm. 



Hab. Kuching, Sarawak. 



Antennae black, covered with a pale microscopic pile. 

 Front, face and clypeus densely covered with silvery pubescence 

 and more sparsely with long pale hair ; the vertex sparsely with 

 long pale hair ; alutaceous ; the lower part of the vertex has a 

 narrow furrow in the middle, which ends, above the ocelli, in a 

 smooth depression. Mandibles black; the palpi testaceous. The 

 basal portion of the median segment has a thin furrow down the 

 middle, which becomes conical ly dilated at the apex ; the furrow 

 on the apical slope is wide and deep. The second and third 

 cubital cellules are equal in length above ; they are as wide 

 there as the space bounded by the two recurrent nervures. 

 Legs black ; the front tarsi testaceous at the apex ; the calcaria
