3(56 ICHNET7MONID.B. 



Simla, 7000 ft., v. 07 (N. Annandale} ; SIKKIM (Knyvett Ind. 



MUS.). EUEOPE. TURKESTAX. 



The coloration of this species is liable to considerable variation, 

 more especially as regards the paler and often flavescent mark- 

 ings ; such plastic features as the metathoracic carinae, scutellar 

 margins and length of the nervelet are also inconstant. 



This is one of the most prevalent of all ICHXEUMOXID.E through- 

 out nearly the whole of Europe, but has not hitherto been known 

 to extend further east; it very frequently flies into houses to 

 artificial light, is found on " sugar " by lepidopterists, and may 

 frequently be remarked flving with an uneven undulatory motion 

 about hedges and in woods. A very long list of hosts has been 

 assigned to it by Bridgman and Fitch (loc. cit.\ which has been 

 extended by later authors ; its parasitism is confined to Lepi- 

 doptera, and is practised almost exclusively among the Bombycid 

 and Noctuid moths.

$ . A red or pale ferruginous species, with the metathorax 

 coarsely trans-strigose and laterally spinose. Head with the eyes, 

 ocelli and apices of the mandibles, black. Tliorax with the 

 mesonotum smooth and nitidulons ; metathorax with two arcuate 

 transverse carinre, the apical at the base of the petiolar area and 

 laterally produced into acute apophyses. Abdomen falcate, glabrous 

 and shining, with fine and short silky pubescence. Wings hyaline 

 and iridescent. 



Length 17 millim.

Waterhouse s figure is too rough to assist in determining the 

 position of this species to any material extent, though the alar 

 neuration as there indicated shows the second recurrent to be 

 emitted before the apex of the basal radial abscissa, which allies it 

 with 0. luteus, but the apophyses render it sufficiently distinct. 



I have seen a male, captured in Sikkim, which differs from 

 Opliion luteus, L., only in its slightly more prominent apophyses.

Ophion areolatus, Cameron, Manch. Mem. 1899, p. 101 (?c?). 



d . General colour testaceous-red. Head not constricted pos- 

 teriorly ; orbits broadly and the vertex pale flavous, occiput and 

 the finely punctate face yellowish ferruginous ; clypeus finely and 

 distinctly punctate, basally discrete, with deep and oblique lateral 

 sulci ; mandibles glabrous, centrally punctate, basally flavous, with
