As pointed out by Bnies^ OphioneMus Westwood and {Pharsalia 

 Cresson) =nyvienopharsaUa Morley are probably distinct genera. 

 The former is unknown to me. Of the latter the National Collection 

 contains four species, two of which are new. 



These two genera form a group in which the venation is very 

 anomalous but not, I believe, of subfamily significance. Morley" 

 has shown, though his terminology of the veins is very confusing, 

 that what veins are present in the front wing are entirely analogous 

 with those of {Nototrachys)=Anomalon. One feature of the vena- 

 tion which Morley overlooked, but to which Roman " calls attention,

is the movement of inlercubitella far basad of its normal position for 

 the Ichneumonidae, farther even than in the Cremastini. This to- 

 gether with the basal position of the nervellus gives the hind wing a 

 strongl}^ braconoid appearance. On the whole the venation (fig. 1) 

 of this group is the extfeme development of the form exhibited by 

 Anomalon and the Cremastini. This consists in the retreating of the 

 apical transverse veins toward the base of the wing with subsequent 

 weakening of the apical abscissae of the longitudinal veins. Thus in 

 various gi'oups we have the second recurrent very close to, interstitial 

 with, or even basad of the intercubitus ; the very narrow base of the 

 second discoidal cell, which in some cases at least seems to be due not 

 so much to the upward movement of subdiscoideus as to the baseward 

 movement of the postnervulus ; and the great reduction of the basal 

 abscissa of radiella (abcissula of Roman). 



In the present group the baseward trend of the venation has gone 

 so far that the apical abscissa of cubitus and the entire second recur-
