ART. 21. NEW SPECIES OF ICHNEUMON-FLIES CUSHMAN. 15 



rent and subdiscoideus have dropped out, althou<i-h the longitudinal 

 veins are represented by streaks. The position of the second recur- 

 rent is not even indicated (Morley to the contrary), for the bulla- 

 tion of discocubitus is distinct and there is apicad of this no angula- 

 tion or thickening to indicate the possible position of recurrent. The 

 postnervulus has moved back, the lower end even farther than the 

 upper end, while the trace of subdiscoideus issues from the apex of 

 discoideus instead of from its normal position at some point on post- 

 nervulus. The loss of practically the entire median vein in both 

 front and hind wings is a secondary feature. 



In the hind wing radiella is represented by a very short abscissula, 

 nervellus is very close to the base, and mediella is missing, while all 

 longitudinal veins apicad of intercubitella and the lower end of 

 nervellus are lost. 



Because of the deep mesopleural furrow and certain other charac- 

 ters Roman professes to see a tendency in Pharsalia toward Gasterwp- 

 tio7i^ in w^hich view I can not share. These features are, it seems to 

 me, secondary developments rather than fundamental. The group 

 is, in my opinion, entirely Ophionine in its relationship, but because 

 of its very anomalous characters fully worthy of tribal rank, falling 

 between the Therionini and (Nototrachini)=Anomalini and some- 

 what more closely related to the former through Parano7nalon and 

 LdbrorycJius than to the latter. About the only respect in which 

 it resembles Anomalon more than Paranomalon is in the possession 

 of only a single calcarium on the middle tibia. In the form of the 

 head Avith its very broad occiput, which has a secondary carina en- 

 circling the cervical foramen ; the flat or concave and strongly mar- 

 gined scutellum; the usually swollen hind tarsi; the very narrow 

 stigma; the unswollen middle and front tibiae; the \QYy long tro- 

 chanters ; and short ovipositor it is more like the Therionini. 



Genus OPHIONELLUS Westwood. 



OpMonellus Westwood, Thes. Ent. Oxon., 1874, p. 128, pi. 24, fig. 3. 



In his description of OpMonellus manni Brues includes some char- 

 acters that are apparently generic in significance, as follows : Frons 

 with a deep impression which includes median ocellus; mesoscutum 

 shining reticulate ; scutellum flat ; mesopleural groove coarsely retic- 

 ulated.
