HYMENOPTERA OF SARAWAK. 1 1 5 



apex of the anterior (especially the radial cellule) fuscous vio- 

 laceous, the nervures and stigma black. 6 . 



Length 28 mm. 



Kuching. 



Face closely punctured, thickly covered with short white 

 pubescence. Clypeus smooth, broadly depressed in the middle, 

 broadly bilobate. Labrum bilobate, the lobes more widely 

 separated than those of the clypeus, darker coloured and more 

 oblique. The striation on the mesonotum is coarse ; on the 

 apex in the middle it is closer and more rugose, more reticulated. 

 Scutellum finely, irregularly transversely striated ; the rest of 

 the thorax and the abdomen is smooth and shining. The basal 

 abscissa of the radius is straight and oblique, the apical is 

 broadly roundly curved towards the costa ; the recurrent nervure 

 is received beyond the transverse cubital at a slightly greater 

 distance than the length of the latter ; the transverse median 

 nervure is received shortly beyond the latter ; the transverse 

 median nervure in the hind wings is broken near the top. 

 Antennas slightly serrate towards the apex ; the scape is yellow 

 below. The hind tibiae are brownish above, yellowish below. 

 Mandibles black, shortly, bluntly bidentate. Palpi yellow. 

 Temples short, rounded. The tubercles are prominent ; the 

 lower part of the metapleurse project into prominent tubercles, 

 longer than wide, somewhat pyriform, dilated posteriorly above. 

 The 1st segment of the abdomen is long, narrow, about one 

 fourth longer than the 2nd. The disco-cubital nervure is only 

 indistinctly broken. The occiput is almost transverse. 



Taking this species as a typical Epirhyssa, the latter genus 

 may be separated from Bhyssa thus : 



Fore wings with an areolet ; the 1st abdominal segment 



shorter than the 2nd Bhyssa 



Fore wings without an areolet, the 1st abdominal seg- 

 ment clearly longer than the 2nd Epirhyssa Cr. 



The agreement with them otherwise is very close. In 

 Epirhyssa spiloptera Cam., from Borneo, the 1st abdominal 

 segment is hardly longer than the 2nd in the 9 .
