This is a stout, robust species. Ichneumon exesus, sp. nov. (Fig. 25.) Female. Length 13 mm. Yellowish; the head, parts of the thorax and bands on the abdomen black. Head probably entirely black; the antennae brownish yellow, darker basally. Basal joints of flagellum three or four times as long as thick; the apical ones becoming transverse, twice as wide as long; the antennae being moderately stout. Scutellum rather strongly transversely elevated, with a depression at its base which is margined by carinae laterally. Metanotum with the median areola large and quadrate; basal and middle lateral ones separated. Abdomen stout, the petiole narrow and rather strongly elevated apically, the postpetiole being also nar- row. Legs brownish yellow, Fig. 25.— Ichneumon exesus, sp. nov. Type, the posterior femora darker, and the tips of the tibiae and tarsi blackish. Wings hyaline, stigma and veins dark fuscous; the former narrow, whitish at the base. Marginal cell wider than in the preceding species, the second section of the radius only one- third longer than the first. Areolet large, obliquely pentangular, the upper side the shortest; discocubital vein not curved, broken at the middle by a short stump of a vein; submedian cell no longer than the median. Described from one specimen and reverse. Type.— Nos. 2112-2113, M. C. Z., Florissant, Col. (Nos. 8436 and 9126 (reverse) S. H. Scudder Coll.). Ichneumon torpefactus, sp. nov. (Fig. 26.) Female. Length 10 mm. Dark colored, wings hyaline, the abdomen conspicuously banded. Head strongly transverse; the antennae slender, with a pale annulus at the middle. First flagellar joint four times as long as thick; second and third equal, each three-fourths as long as the first and three times as long as thick; joints beyond the annulus strongly
