HYMENOPTERA OF SARAWAK. 145 



striated, the striae more irregularly and widely separated on the 

 apex below ; the lower part at the base closely punctured ; 

 raetapleuraa strongly, closely rugosely punctured, its lower edge 

 with a distinct border. Petiole shining, the post-petiole punc- 

 tured, but not closely or strongly, the 2nd and 3rd segments 

 opaque closely, distinctly punctured. This species may be 

 separated from V. spinosa as follows : — 



Lower outer orbits yellow, not densely pilose ; the metanotal 



spines not united by a yellow line, the face yellow. Armata. 



Lower outer orbits and face black ; the cheeks densely pilose ; 



the metanotal spines united by a curved yellow line, the 



face black. Spinosa. 



Coesula, gen. nov. 



Transverse median nervure in hind wings broken below the 

 middle ; median nervure at the base roundly curved towards 

 the costa. Areolet minute, open at the apex. Gubito-disco 

 nervure angled in the middle, and with a minute stump of a 

 nervure. Transverse median nervure interstitial. Median seg- 

 ment with 2 transverse keels : a longitudinal furrow between 

 them ; its spiracles small, oval, not much longer than broad. 

 Antennae longer than the body, thickened and broadly ringed 

 with white in the middle ; the basal joints of Hagellum greatly 

 elongated ; the basal two equal in length. Clypeus roundly 

 convex; its sides and apex depressed; malar space almost ob- 

 solete ; temples very short. First abdominal segment as long 

 as the 2nd, broad at the base, becoming gradually wider to- 

 wards the apex; not much curved, not bent or elbowed ; the seg- 

 ment banded with white at the apex ; ovipositor short. 



The median segment is short and has a somewhat steep 

 rounded slope on the apex'; its sides finely striated ; the areola 

 is only defined at the apex ; on the base is a* closely striated 

 depression ; its apex is irregularly rugosely striated^ the basal 

 keel extends to the mesonotum. Thorax fully 3 times longer 

 than wide; its sutures moderately deep. Claws slender, long- 

 ish ; the last joint of hind tarsi distincly shorter than the 

 3rd. Head wider than the thorax. Spiracles of 1st abdominal 

 segment closer to each other than to the apex of the 

 segment.
