ICHNEUMON-FLIES — GELINAE : MESOSTENINI 295 



metapleurimi, thoracic sterna, and coxae entirely black, sometimes 

 black marldngs restricted to occiput, thoracic sutures and apices of 

 coxae; basal 0.45 of flagellum fulvous brown and fuscous (in various 

 proportions), beyond which is a yellowish or fulvous band, the apical 

 0.35 of flagellum black; hind femur and tibia entirely fulvoferruginous 

 or more or less blackish; Avings orange yellow banded with dark brown, 

 as in female; second and third tergites, sometimes also fourth and 

 fifth, and rarely also the sixth tergite fuscous at base. 



Female: Front wing 10.5 to 13.0 mm. long; temple and mandible 

 as described for the male; second segment of flagellum about 2.9 as 

 long as ^vide; i:)unctures on mesopleurum small, sharp, and dense, 

 just below middle of mesopleurum crowded to form rugulosity; basal 

 transverse carina of propodeum indistinct, entirely absent sublater- 

 ally; apical carina of propodeum indistinct sublaterally, elsewhere 

 absent; hind femur about 5.0 as long as deep; setiferous punctures on 

 second tergite all very dense, separated by about 0.6 the length of 

 the hairs, which are quite short; ovipositor sheath about 0.55 as long 

 as front wing; ovipositor about 4.2 as long from nodus to apex as it 

 is deep at nodus, 



Fulvoferruginous. Flagellum medially vnih a subcomplete whitish 

 band, basad of which it is fulvous, the apical part missing from speci- 

 mens at hand; some thoracic sutural markings black; front \ving
