Extiasfes.] BRITISH ICHNEUMONS. 301 



Both sexes were described by Desvignes from examples, with no 

 locality, in his own collection; but Fred. Smith writes (Ent. Ann. 1857, 

 p. 33) in his Notes on Hymenoptera in 1856, "I captured about a dozen 

 specimens of Exeiasies feniorator, a species first described by Mr. 

 Desvignes, in his Catalogue of British Ichneumonidae, recently published 

 by the Trustees of the British Museum. This insect has not been met 

 with in any other locality than the Deal Sands, where I found it. Its 

 mode of running and flying so closely resembles a Pompihis, that at first 

 sight I mistook it for one." These specimens were almost certainly identi- 

 fied by Desvignes himself, and two females labelled " Deal 1856" are in 

 the British Museum, with the types of both sexes. There is no later 

 record of the male, but the female has been taken by Brischke in Prussia 

 and by Holmgren in Sweden.

A stout species with red body and femora. Head as broad as thorax, 

 punctate and somewhat broad behind the eyes, with brown pilosity ; cly- 

 peus deplanate and apically truncate ; mandibles punctate with the apical 

 teeth of equal length ; palpi infuscate. Antennae immaculate and some- 

 what stout ; of S hardly as long as, of 9 distinctly shorter than the body ; 

 flagellar joint somewhat discreted. Thorax stout and pilose, gibbulous 

 and punctate ; notauli obsolete ; metathorax rugulosely punctate with the 

 areae and apophyses wanting ; petiolar area short and basally incom- 

 plete ; spiracles linear. Scutcllum black and distinctly punctate. Abdo- 

 men not broad, glabrous and nitidulous ; with the second, third, apex of 

 the first and often more or less of the fourth segment, red ; basal seg- 

 ment subelevated in front and a little curved, straighter in ^, with the 

 spiracles conspicuous and often a discal fovea before the apex ; plica red ; 

 terebra as long as the basal segment, with linear valvulae. Legs somewhat 

 stout and red ; coxae and trochanters black ; the hind tarsi and more or 

 less of the apices of their tibiae infuscate, with the fourth and fifth joints 

 of the former rufescent or in ^ sometimes whitish ; tarsal claws short. 

 Wings clouded, stigma dull fulvescent; areold irn^gular, sessile or petio- 

 late. Length, 7 — 10 mm. 



The forms /^/(yAvv^Z/cv and f/v^.v.v/cv a])i)ear to dilTcr in nothing essential 

 but their slightly larger sixe and stouter conformation {cf. Holmgren, I.e.). 

 Thomson hesitated to associate the former on account of (Iravenhorst's 

 insistence upon the divergcmr oi" abdominal shape ; to the latter he 

 makes no reference.
