I02 BRITISH ICHNEUMONS. [^Panargyrops. 



obovate bodies, and especially in their long and slender legs and antennae, 

 and Hemiteles, though perhaps more nearly ajiproaching the latter ; in fact 

 they appear to form a very natural and distinct link between the two 

 grou[)s. The coloration of most of the species is similar and different 

 from that of either group in the delicate red of the disc of the abdomen, 

 which gradually merges into the infuscate lateral margins. In the peculiarly 

 long and dense pubescence and the shape of the abdomen (except the 

 basal segment) the males are liable to become intermixed with the Try- 

 phonid genus AdeLn^tuxllnis, Hoimgr., with which Ciravenhorst confused 

 some of this group. Brischke recognized this genus, though he was of the 

 erroneous opinion that it might constitute C/iaeretymtnn, F5rst. For some 

 occult reason British authors have confused it with Neiiiafopodius, which 

 is very abundantly distinct, but Brischke did not do so, although their 

 error doubtless arose from his mode of classification which made it appear 

 as though his Cryptus ater belonged to that genus at first sight. Great 

 confusion has hitherto existed in this genus, which has been in no way 

 mitigated by Schmiedeknecht, and the records of localities and hosts must 

 consequently be regarded with due caution.
