AKT. 16 NORTH AMERICAN ICHNEUMON-FLIES CUSHMAN 27 



in the present paper to Diapetimiovplia also run in Ashmead to 

 Crypturopsis^ and it may be that aiinatxis should be assigned there. 

 Rohwer's notes do not mention the form of the areolct, nor does the 

 ori<?inal description. The form of the propodeal apophyses appears 

 from the description to be more like that of Diapetvmorpha. Because 

 of this doubt I have keyed the species out under both <i:enera. 



The following is a rearranged translation of Provancher's de- 

 scription with additions from Rohwer's notes: 



Female. — Length, 10 mm. 



Robust; antennae stout; notauli well defined in anterior fourth; 

 sternauli foveolate; scutellar fovea foveolate, scutellum shining, im- 

 punctate; propodeum rugose posteriorly, apophyses thornlike; are- 

 olet small, second intercubitus obsolete; abdomen short oval; post- 

 petiole broad; ovipositor shorter than abdomen. 



Black with the following white markings : Clypeus, spot on man- 

 dible, palpi, annulus beyond middle of antenna, spots on anterior 

 angles of pronotum, tegulae, subalar tubercles, a small spot above 

 middle coxae, scutellum, postscutellum, spots on upper and lower 

 divisions of metapleurum, apophyses, and apical margins of all 

 tergites; first tergite, except apex, and a line on second between the 

 black and white red; antennae, except annulus, black; legs, includ- 

 ing coxae and trochanters, red. 



Known only from the type, which is from Ottawa, Ontario.

Discussion based on type, a specimen compared with the type, the 

 type and paratype of alhomacmlatus and one other specimen. 



Known only in the male, unless, as seems likely, it is the male of 

 andax. 



Differs from the male of texunus as follows: Mesoscutum very 

 densely punctate, notauli distinct anteriorly; white of posterior or- 

 bits at most narrowly interrupted above; malar space frequently 

 black; a white spot on each side of mesosternum close to st<irnauli', 

 apophyses somewhat more prominent and less smoothly rounded, 

 the yellow spots extending farther from their bases; all coxae and
