140 HYMENOPTEEA. 



6. Ichneumon bilimeki. (Tab. VII. fig. 6.) 



Niger; geniculis anterioribus, tibiis tarsisque flavo-testaceis, apice tibiarum posticarum nigris; aKs flavo- 



famatis, stigmate nervisque flavis. g . 

 Long. 15 millim. 



Hab. Mexico (BilimeTc). 



Antennae nearly as long as the thorax and abdomen together, stout, covered with a 

 short close pile. Head closely and strongly punctured, the face not projecting, covered 

 with a longish pubescence. Thorax closely and strongly punctured, semiopaque ; the 

 pleurae more shining, and longitudinally striated in the middle. Scutellum flattish, not 

 much raised above the mesonotum, and punctured like it. All the areas on metanotum 

 distinct ; the supramedian not much broader than long, the sides curved. All the 

 thorax covered (but especially the disc) with a close pile. Petiole closely aciculated, 

 more strongly and still more closely at the apex ; the sides bordered. Gastrocceli longer 

 than broad, deep, striated irregularly ; the rest of abdomen closely punctured through- 

 out, opaque, and covered with a close pile. Posterior coxae strongly punctured, the 

 four anterior coxae less strongly so ; trochanters finely, femora obscurely, punctured. 

 Areolet 5-angled, the lower part sharply angled ; the upper sides narrowed above. 

 The apex of the wing is not so yellow in colour as the rest, the smoky tint there being 

 quite noticeable. On the face, touching the eyes, there are two small yellow spots. 



Closely allied to I. semiobscurus, but differing from it in the yellowish wings, stigma, 

 and nervures, by the postpetiole not being so distinctly raised in the centre, and by the 

 areolet being wider at the top. 



7. Ichneumon chiriquensis. 



Niger ; antennas, tegulis, tibiis, femoribus tarsisque anterioribus sordide testaceis ; alis hyalinis, stigmate et 



costa testaceis, nervis fuscis. c? . 

 Long. 14 millim. 



Hab. Panama, Volcan de Chiriqui 4000 to 5000 feet (Champion). 



Head and thorax covered with a dense fuscous pubescence, which is especially long 

 on the breast, and marked with shallow punctures, which are all clearly separated ; the 

 mesopleurae smooth, shining, impunctate. Head excavated above the antennae, not 

 buccate ; with a suture running down from the front ocellus. Scutellum rounded, not 

 much elevated, longer than broad, rounded at the base and apex ; shining, the disc 

 bearing scattered punctures, the sides with a few longitudinal striations. Postscutellum 

 aciculated, the scutum on either side of it largely depressed, shining, obscurely acicu- 

 lated. Metathorax opaque, transversely striated all over ; the areas entirely obliterated. 

 Petiole broad, the base not much narrower than the apex; basal half smooth and 

 shining, depressed in the middle ; apical portion also depressed in the middle, and with 

 a blunt tubercle on each side at the part where it unites with the smooth basal half; 

 apical half aciculated, covered with large punctures, except the extreme apex, which 

 is smooth, shining, and a little raised above the next segment, especially in the middle,
