242 ICHNEUMONID^. 



radix and tegulae testaceous, stigma piceous and the bifenestrate 

 Becond recurrent nervure emitted by the cubital far beyond the 

 submai'ginal ; first recurrent of hind wings emitting the nervelhis 

 ahnost from its junction witli the posterior nervure. 



Length 0.7 miUim. 



SiKKiAi : Eungarum, 5700 ft., iv. 1900 {Col. Bhu/ham). 



Type in the British Museum. 



This very distinct species may be known from all others by the 

 structure of its flagellum. Described from a single specimen. 



Tribe BANCHIDES. 



In spite of all that has at various times been written by 

 Holmgren, Thomson and other authors to the contrary, I am 

 still of the opinion expi-essed in my volume on the British 

 PiiiPLiN.^, that this aberrant group of Ichneumons bears features 

 of closer relationship with certain Pimplin.i; than with the 

 Ophionin^ or Tryphoxin.t]:, among which they are usually placed. 

 On the one hand, they resemble Accenitus in the subsessile abdo- 

 men, narrow w'ings aud elongate legs, and, on the other, their 

 relationship with the Lissonotid genus Meniscus is well attested 

 by Gravenhorst, who described the same insect, under different 

 names, in both groups. The rhomboidal areolet, which character 

 is somewhat strained in the Oriental representatives, and sub- 

 sessile abdomen exclude them from the IcHNEUMO?fiNiE and 

 CEYPTiK.i: ; the lack of a distinct petiole also will not permit of 

 their inclusion in the Ophionij^.^e ; aud the distinctly exserted 

 ovipositor of at least Tegona and Exetastes, seems to preclude 

 them from the Trtphonin.e, wherein the. anus is never distinctly 

 compressed as in Batichus, though this feature is met with to a 

 modified extent in the Ac.exitides. They appear to be parasitic 

 exclusively on the Lepidoptera, among which they evince a 

 predilection for the Noctuid^.
