Except for slightly larger size the paratype is practically identical 

 with the type. 



Genus PHRUDUS Foerster 



The name Phrudus was first used by Foerster in his Synopsis der 



Familien und Gattingen der Ichneumonen/ but Foerster neither 



-designated a genotype nor included species in the genus, and the only 



description of the genus consists of the characters leading to it in 



his key. 



In 1886 Bridgman ® also described a genus Phrudus based on the 

 single species, Phrudus vionilicomis Bridgman. 



In 1901 StrobP described his Ktenostiliynus with aequaearticu- 

 latus Strobl as genotype. 



In 1914 Roman ^° brought forth his genus Yendolus^ based on 

 Vendolus stilpninus Roman. 



Roman ^^ later synonymized Ktenostilpnus and Vendolus with 

 Phrudus Bridgman and his own Vendolus stilpninus with monilicor- 

 nis Bridgman. 



Thomson, Roman, and Morley credit the genus to Bridgman, while 

 Schmiedeknecht, Dalla Torre, and Viereck treat it as Foerster's. 

 That Bridgman's genus is the same as Foerster's there can, I think, 

 be little doubt. In Foerster's key to the Ctenopelmoidae monilicomis 

 will certainly run to Phrudus. Also, it agrees with Foerster's un- 

 published description of his genus, which, translated, is as follows: 



Antennae 20-jointed, first flagellar joint a little longer than second^ 

 clypeus distinctly separated; propodeum distinctly areolated; first 

 tergite narrow, spiracles in middle; radius originating at middle of 

 stigma; areolet irregular, sessile; cubitus obsolete beyond areolet; 

 median vein in hind 'wing effaced basally ; nervellus not broken. 



Furthermore, Bridgman apparently permitted Thomson to see his 

 species before its publication, for he credits Thomson with having 

 suggested the name. And Thomson habitually used Foerster's names 

 without crediting them to Foerster, simply using the latter author's 

 work as a convenient source of generic names. The synonymy of the 

 genus is therefore as follows :
