124 PIMPLINE ICHNEUMONIDAE 



The following synoptic table leading to the tribe Pimplini is 

 taken from the ()2nd fascicle of the Genera Insectorum. 



1. Head more or less cubical, more rarely globular. Mandibles extended, 



and with the clypeus downwardly bent at the tip, as a rule, forming the 



mouth opening. Antennae and legs mostly long and thin, Tribe Xoridini 



Head transverse, rarely somewhat elevated. Mandibles with the clypeus 



fonning no apparent mouth opening 2 



2. Abdomen depressed, rarely somewhat compressed at the tip. The last 



abdominal segment not large. Hind legs, particularly, not the hind coxae, 

 neither strikingly long nor stout. Antennae almost entirely long and 



slender 3 



Abdomen behind more or less laterally compressed. The last ventral 

 segment, generally plow-share shaped and standing out, sometimes very 

 large, lancet-shaped, very rarely small and transverse. Hind legs or 

 at least hind coxae strongly lengthened and generally strongly thickened. 



Antennae more or less short and stout, 



(Tribes not included in this paper) 



3. Abdomen with more or less distinct impressions, mostly also strongly 



punctured. When smoother and without elevations, then segments 

 2 to 5 have deep impressed, obhque lines on both sides which converge 



toward the middle of the base Tribe Pimplini 



Abdomen without, or with entirely indistinct impressions, and without 

 coarse sculpturing, more or less smooth or finely punctured or leather- 

 like Tribe Lissonotini 



The characters of the tribe Pimplini are: Head transverse, 

 rarely somewhat elevated. Abdomen depressed, only toward 

 the end mostly compressed, with more or less distinct impressions 

 or elevations, usually punctured, rarely smooth, if smooth 

 alutaceous or coriaceous, always with lateral impressed lines 

 on segments 2 to 5 which converge toward the middle of the 

 base. Mandibles with front border of clypeus not forming a 

 mouth-opening. Hind legs not conspicuously lengthened and 

 thickened.
