BRITISH ICHNEUMONS. 289 



among his Ichneumones, and expressed the opinion, followed practically 

 by Woldstedt, that its position was intermediate between the Ichtieumflninae 

 and the Tryphoni)iae, to which latter the structure of the metathorax and 

 basal segment bears afifinity. Forster excluded it from the Ichneumones 

 proper; and no mention is made of this tribe in Berthoumieu's work 

 on the present sub- family, since he considered that it belonged to the 

 Tryphoninae. Holmgren, in 1864, thought it allied to the Xorides, but 

 in 1878 he gives it under a family of equal rank with all the remaining 

 Ichneumoninae. Brischke, again, goes even so far, perhaps casually, as to 

 insert it at the end of the Cryptinne, after Pezomachus. Thomson (Opusc. 

 Ent. xii. 1235) has entered somewhat at length into this vexed question, 

 and points out the relationship of the tribe with his genus SpiUchneumon 

 in its strongly developed hypopygium, large head, stout mandibles, and 

 short legs, of which the anterior tibiae are strongly spinose ; he is decidedly 

 of opinion that that here assigned to it is the best position that can 

 be found. Finally Ashmead, in 1900, places it in a tribe, ranking with 

 my Fkaeoginiiii, though standing in the midst of the Cyclop ne us tici, after 

 the end of which is probably its most natural position in our present 

 classification. Only one genus and species is known.
