This subfamily, with the exception of possibly the Ichneumomtue, 

 can be easily separated from all the others by the characters made 

 use of in my table of subfamilies. With the suljfamily mentioned, 

 however, it is different, since the species falling in it are exceedingly 

 closely allied, and the males especially are separated, or placed, 

 with difficulty. The females, however, ma}' be easily disting-uished, 

 'except in a few cases, b}" the prominent, exserted ovipositor, and the 

 position of the spiracles of the first abdominal segment. 



Both sexes, however, possess a character not found in the Ic/meu- 

 moiiinnce, viz, a more or less distinct, long Itudinal grooved line or farrow^ 

 sometimes punctate or crenidate^ situated low down on the mesopleura 

 and ivhich separates the inesosfern urn. from these sclerites. This char- 

 acter may always be depended upon to separate a cryptine from an 

 ichneumonine. 



Seven distinct minor groups, or tribes, may ])e distinguished, sep- 

 arated as follows: 



TABLE OF TRIBES. 



Metatliorax irithout distinct longitudinal carinte or at the most with only the j^leural 

 carinte present, the petiolar area always wanting, usually with one 

 or two transverse carin.'e or with none; stigma most frequently nar- 

 rowed, lanceolate; apterous and subapterous forms common 2 



Metatliorax iritlt longitudinal carinte and usually more or less completely areolated, 

 the petiolar area present; stigma usually widened, triangular, sub- 

 triangular, or ovate; snliapterous forms rare.
