ICHNKUMONID GENERA LABIUM AND PGECILOCRYPTUS. 



19 



The male has the face almost square, the sculpture is somewlia,t 

 coarser, especially on the median segment. The sculpture of the 

 areola in the male shows considerable variation; in some speci- 

 mens there are coarse transverse rugee, which are only rather 

 feebly indicated in others. The teeth on the sides of the petiole 

 are remarkable, also the sexual coloxir differences. 



The female is the type.

This species is allied to montivagmn in having a distinct tooth 

 on each side of the petiole between the spiracles and the base 

 and also in the sculpture, but differs in the almost entirely 

 fulvous antennae, in the ferruginous colour of the front, vertex 

 and propleurfe, a.nd in the position of the second recurrent ner- 

 vure which is received close to the apex of the areolet. 



This is very doubtfully distinct from ferrugineum Cam., but 

 differs in the colour of the antennae. The other differences given

by Morley either fall within the range of individual variation or 

 a.re taken from one or other of the three males marked by him 

 as co-types, one of which is certainly specifically distinct, not at 

 all nearly related to the other two, in which the thorax is mostly 

 black, having only the mesonotum and a patch on the meso- 

 pleuras ferruginous. These are probably the true males of 

 clavicorne, which species probably takes the place of montivayum 

 on the mainland.

This species seems to differ from clavicorne, Mori, only in the 

 colour of the antennpe, which are black above and brownish on 

 the apical half beneath ; the scape is yellow beneath in both 

 forms. Cameron's type is in a dirty condition.
