ICHNEUMON-FLIES — GELINAEI MESOSTENINI 49 



moderately small pimctm'es that are separated by about 0.8 their 

 diameter; mesopleurum a little shining, with close, fine, strong wrin- 

 kling; mesoscutmn polished, with sharp, medium-sized punctures 

 that are separated by about 0.6 their diameter; intercubiti faintly 

 convergent anteriorly, the areolet subquadrate; second tergite mat, 

 with large shallow punctures that are separated by about 0.6 their 

 diameter; ovipositor tip as in figure 32 7, c. 



Colored like the female of A. alutarius except that the palpi are a 

 little darker, there is very little fuscous at apex of hind femur, and 

 wings are more distinctly infuscate.

 convex; face rather wide, weakly mat, with fine punctures that are 

 separated by about 1.8 their diameter, its median 0.25 ± more 

 strongly convex; mesopleurum with fine, weak, moderately sparse 

 punctures, in places with fine wrinkling that is mostly longitudinal; 

 mesoscutum polished, with small punctures that are separated by 

 about twice their diameter; intercubiti strongly convergent anteriorly, 

 the areolet pentagonal; second tergite weakly mat, with small punc- 

 tures that are separated by about 1.4 their diameter in male, by about 

 1.8 their diameter in female; ovipositor tip as in figure 327, d.
