122 BRITISH ICHNEUMONS. {^Pynumon 



There can, I think from the description of Hartig's preoccupied genus 

 Ophiodis (altered to Ophiogastra by Ashmead, Canad. Entoni. 1900, p. 368), 

 be no doubt whatever that at least the female of his O. monlanus belongs 

 to the present genus, Holmgren's name for which I retain as having 

 priority over Ashmead's.

Pymcmon obscuripes, Holmgr. Sv. Ak. Handl. 1858, p. 102; Thorns. O.E. xi. 

 110, ? . 



A black species with grey pubescence and vertex strongly dilated 

 behind the eyes ; mouth and tegulae rufescent, stigma infuscate; anterior 

 legs red with coxae and base of trochanters black ; hind legs nigrescent 

 with only apices of trochanters and base of their femora dull ferrugineous. 

 Length, 7-9 mm. 



This species, of which the (J is still unknown, is recognised by the 

 very dark hind legs, rufescent and not black tegulae, centrally angular 

 clypeus and very broad vertex. 



Holmgren only knew it in Sweden "in Bahusia; prope urbem Gotho- 

 burgum," and it was not again found on the Continent till Thomson 

 recorded it in 1887 as " funnen vid Glimakra i Skane " and at Borgholm 

 in the Baltic Isle of (3Iand. Elsewhere it is solely recorded from Austria 

 and Schmiedeknecht took it there in 1908 on tree-trunks at Seis, in South 

 Tyrol. This is the only one of the nine palaearctic species hitherto 

 recorded as British ; it figures in both Marshall's catalogues, and its 

 inclusion would appear to rest upon Francis Walker's iSbq capture, ''■' 

 enumerated in the former's " Ichneumonidae of the Isle of Man" 

 (Entom. 1872-3, p. 432), since none of our other local lists contains it. 



2. montanus, Htg. 



Caiiipoplex tnegacephahis, Gr. I.E. iii. 502, ? , excl. var. (?). Ophiodes 

 montanus, Htg. Ber. Naturw. Ver. Harz. 1847, col. 19, excl. j . Pyracmon 

 mehmurus, Holmgr. Sv. Ak. Handl. 1858, p. 102, s ? ; Thorns. O.E. xi. 1110, ? . 



A black species with grey pubescence, the areolet not sessile and tere- 

 bra longer than half abdomen; mouth and tegulae pure white, stigma 

 obscurely infuscate; scape beneath and all the legs red with coxae, 

 trochanters, and the hind legs apically black. Length, 6-8 mm. 



Thomson considered Holmgren's species a link between the present 

 genus and Nnnenlis gracilis with its anterior trochanterellus stramineous, 

 the hind ones red ; the second segment apically dilated and the four 

 following gradually more strongly compressed, the metathoracic carinae 

 very distinct and mouth pale. 



Gravenhorst's single V (i^ot both sexes as given by DT., copied by 

 Schm.), which seems almost certainly synonymous, was from Lusatia; 

 Holmgren took males (this sex was unknown to, not thought distinct by,
