has the post-petiole punctured centrally, which is not the case 

 with our species. In Cresson's synopsis of American Ichneumons 

 this runs near c&ruleus but the black scutellum and other color 

 characters will readily separate it from that species. 



Female. Length, 11 mm. Anterior margin of the clypeus produced into 

 a low, obtusely triangular, median tooth; supraclypeal fovese punctiform, 

 deep; the median basal portion of the supraclypeal area convex, separated 

 from the bases of the antennae by a distinct carina; anterior ocellus in a 

 broad, shallow depression; postocellar line one-third longer than the ocell- 

 ocular line; flagellum filiform, first joint slightly longer than the second; 

 face and front with distinct well defined separate punctures; vertex and 

 posterior orbits nearly impunctate; mesoscutum granular with dense seti- 

 gerous punctures; scutellum more sparsely punctured than the scutum; 

 mesepisternum punctured similarly to the scutellum; sides of the propodeum 

 sculptured like the mesepisternum; posterior aspect of the propodeum 

 with large, confluent, close, punctures; basal lateral area with rather large 

 distinct punctures; areola, basal lateral area and basal area almost impunc-

tate; areolation as in figure 1; the central portion of the post -petiole finely, 

 longitudinally aciculate; gastrocoeli well defined; basal portion of the sec- 

 ond tergite longitudinally striate, the remaining portion longitudinally 

 striato-punctate; the base of the third and fourth segments striato-punc- 

 tate, the remining portion sparsely punctured, following segments prac- 

 tically impunctate; apical sternite truncate apically; empodia large, well 

 defined, median portion membranous; legs normal; areolet pentagonal. 

 Dark blue black; inner margin of the eyes almost to the vertex, spot at 

 the summit of the eye, posterior margin of the eye, lateral margin of the dor- 

 sal posterior margin of the pronotum, top of mesepisternum, an incomplete 

 annulus on the ninth, tenth, eleventh and twelfth joints of the flagellum and 

 anterior tibiae beneath, white', wings hyaline, venation black. 



Male. Agrees well with above description of female except in the fol- 

 lowing points: The antennae are somewhat antenniform; the clypeus is 

 nearly truncate; and the color differs as follows: Mandibles except apices, 

 clypeus, face marks produced inwardly so they meet, just below the an- 

 tennae, scape beneath, base of the anterior tarsus, base of the four posterior 

 tibiae, and the base of the four posterior basitarsi, white.
