3(56 ICHNEUMOXIDiB. 



Simla, 7000 ft., v. 07 (N. AnnandaJe) ; Sikkim {Knyvett — Iiul.

The coloration of this species is liable to considerable variation, 

 more especially as regards the paler and often fla\escent mark- 

 ings ; such plastic features as the metathoracic carinas, scutellar 

 margins and length of the nervelet are also inconstant. 



This is one of the most prevalent of all Ichxkumoxid.e through- 

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

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

 artificial light, is fou!id on " sugar " by lepidopterists, and may 

 frequently be remarked flying with an uneven unduhitory motion 

 about hedges antl in woods, A very long list of hosts has been 

 assigned to it by Bridgman and Eitch {ioc. cit.), wliicli has been 

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

 doptera, and is practised almost exclusively among the B(mibycid 

 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. Thorax with the 

 raesonotum smooth and nitidulous ; metathorax with two arcuate 

 transverse carina3, the apical at the base of the petiolar area and 

 laterally produced into acute apophyses. Abdomen falcate, glabrous 

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

 and iridescent. 



Length 17 millim.

Waterliouse 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 diiffers from 

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

 teriorly ; oi'bits broadly and the vertex pale fiavous, occiput and 

 the finely punctate face yellowish ferruginous ; clypeus finely and
