292 BRITISH ICHNEUMONS. [Paniscus 



(13 mm.) long, of a curved form, being- smallest at each extremity, and 

 with lateral fleshy tubercles." Stenton supplements our former know- 

 ledge of the habits of this species (Entom. 10 10, pp. 210-212) by some 

 very close and intimate observations. 



It is recorded from a good many hosts, a large proportion of which 

 are probably assignable to P. cn'stafiis. (Iravenhorst raised it from 

 Bomhyx bifida in October, Bignell on 2nd May in Devon from Odon- 

 iopera hidaiia/a, Rrischke from Eiipithecia ahsynthiata and other (icome- 

 ters in Prussia with Drcpana imguicula and Halias prasinaiia, from 

 which last it was also bred by Giraud, and in Devon on 26th April by 

 Bignell; Bridg. -Fitch, mention (Entom. 1885, p. \^ Eitpithccia succen- 

 iaiiriata ; Stenton induced it (/.r.) to oviposit in Chcimatohia horeata, 

 bnimafa, Hyhernia defoliaria and Oporahia dilutata ; Bignell raised it from 

 Cosmia irapczina in Devon on igth July, Bridgman tells us (Norf. Trans.) 

 that W. Fletcher bred it from Cahera pusaria and Giraud adds (Ann. Soc. 

 Fr. 1877, p. 406) the large Catocala promissa to the victims.

A not very slender species, clear testaceous, with the abdomen usually 

 slightly darker. Head not constricted posteriorly, as broad as eyes, with 

 ocelli large and face flavidous. Antennae sub filiform and distinctly 

 nigrescent from near their base. Thorax not flavous-marked, rarely 

 with somewhat pale mesonotal vittae ; metathoracic transcarina always 

 entirely wanting, its spiracles subcircular. Scutellum indistinctly carinate 

 at most to its centre. Terebra subreflexed and very slightly longer than 

 the truncate anus is high. Hind tarsi whitish. Stigma deej) red or clear 

 luteus ; basal nervure continuous. Length, 6^-9 mm. 



The dark antennae, total lack of metanotal carinae and its subcircu- 

 lar spiracles will render this species distinct, though it is very like P. 

 crisialus\ this distinction is confirmed by the absence of the latter among 

 the numerous examples of the former from Bentley. 



A social insect in the perfect state, or locally common ; it is the most 

 frequent Parabatus in Sweden, Germany, and is said by Schm. to fly 

 round young growth of beech and sycamore in May and June, though 

 nothing is known of its hosts ; France (Gaulle), Holland in August 

 (Burgst), and Belgium commonly from August to October (Tosquinet). I 

 can now find no British record of this species, though it was included by 

 me as indigenous in 1901 ; it is not by any means generally distributed 

 in my experience, and I only possess single specimens from Oxshott in 

 May (Beaumont), Felden (Pifiard), Lyndhurst at the end of JMay (Adams), 

 Devon (Stanley Edwards), (Greenings in June, 1871 (W. Saunders), Shere 

 (Capron), Guestling in i88g (Bloomfield) and Ampton in west Suflblk 

 (Nurse). In the Bentley Woods near Ipswich it is one of the most 

 abundant of all spring Ichneumonidae, constantly seen flying among 

 young birch and hazel trees and settling upon their leaves in the sun, in 

 comj)any with Prionopoda stictica which is so similar, from i6th JMay to 

 i6th June, 1896-1904, though certainly exactb' restricted to that one 

 month at this locality ; I took a male at Assington Thicks, Suflblk, on 

 17th May, 1901, on young birch; but elsewhere I only know it from
