112 HYMENOPTERA FROM SARAWAK. 
nervure is not quite interstitial, being received shortly behind 
the transverse cubital. 
Iphiaulax halesus, sp. nov. 
Ferruginous, the abdomen, antenne except at the base, 
and the hinder legs, black; the fore wings to the transverse 
basal nervure, the 1st cubital cellule and an oblique spot on the 
upper edge of the 2nd cellule, yellowish-hyaline; the petiole 
keeled in the centre; the 2nd and 3rd cubital cellules closely 
longitudinally striated, the basal plate on the 2nd segment 
elongated, the sides and centre keeled; the keel extends to the 
apex of the segment. Face sparsely punctured; there isa 
square depression below the antennz. Parapsidal furrows dis- 
tinct. Petiole broad, as long as the 2nd segment : its lateral keels 
indistinct at the base. ‘The keel bordering the lateral depres- 
sion on the 2nd segment is narrow, straight and oblique; the 
part bordering it on the outerside is closely obliquely striated, 
the apical segments are narrowly lined with pale yellow. Legs 
moderately pilose; the middle tarsi infuscated. ; 
Length 16 mm.; terebra 17-18 mm. 
Hab, Kuching. | 
Antenne shorter than the body; the basal two joints ob- 
scure rufous: the 3rd and 4th joints are about equal in length; 
the 2nd abscissa of the radius is slightly shorter than the 3rd; 
the transverse median nervure is not quite interstitial, being 
received in the discoidal cellule, but almost touching the trans- 
verse basal; and therefore differs from the typical Braconine 
in which it is completely interstitial. In other respects the 
species is a typical [phiaulaa. 
iiii— Head, thorax and fore legs red; the wings yellow at the 
base, hyaline at the apex. 
Iphiaulax crassitarsis, sp. nov. 
Head, thorax, anterior legs, the greater part of the middle 
emora and tibize and the scape of the antennae, ferruginous; the 
asal half of the fore wings yellowish hyaline, the apical clear 
yaline, the hinder wings fuscous, hyaline at the apex; abdomen 
short, ovate, broader than the thorax, closely, but not very dis- | 
inctly or strongly. longitudinally striated. 9.
