the veins and stigma fuscous, the latter narrowly oval or lanceolate. Marginal 

 cell long and narrow; the first section of the radius two- thirds as long as the 

 second. Areolet large and regularly pentangular. Submedian cell slightly 



longer than the median. Legs 

 yellowish, the posterior coxae 

 and trochanters black.

Described from three speci- 

 mens, the type and Nos. 

 2116-2117, Fig. 26, M. C. Z., Florissant, Col., Nos. 4587 and 4294, S. 

 H. Scudder Coll.) which are undoubtedly the same species. There is 

 also a fourth No. 2118, M. C. Z., Florissant, Col. (No. 13,915, S. H. 

 Scudder Coll.) which is doubtfully referable to this species. 



This is a slender species, agreeing with the subgenus Melanichneu- 

 mon in most respects although the postpetiole does not appear to be 

 punctate.

 Type. 



Ichneumon torpefactus, sp. nov. 



Ichneumon provectus, sp. nov. (Fig. 27.) 



Female. Length 8 mm. Black or dark colored, the abdomen considera- 

 bly lighter on the apical half and along the sutures between the segments. 

 Antennae slender, the basal joints of the flagellum elongate, the first to fifth 

 each at least two and one-fourth times as long as thick, the first being about 

 four and the second three times as long as thick; joints toward the apex 

 becoming broader and 

 short, quite distinctly 

 transverse. Surface of 

 head minutely punctulate 

 above as is also the meso- 

 notum; posterior part of 

 head and pleurae smooth. 

 Metanotum completely 

 areolated, although it is 

 possible that the basal and 



middle lateral areas may be confluent. Abdomen elongate, slender; post- 

 petiole smooth or nearly so. Ovipositor rather strongly exserted. Legs 

 moderately stout, the hind pair brownish, with the tibiae paler, the tips 

 of the latter and the tarsi black. Wings hyaline, with pale fuscous veins; 

 first section of the radius fully two-thirds the length of the second; areolet 

 rather small, its upper side shortened until it is quite irregular in shape ; dis-
