298 BRITISH ICHNEUMONS. [Panisais 



but 8| mm. in length. With these larvae, Clutten also sent twenty-six 

 cocoons of the same parasite, raised from ]\I.flucttinfa?i\. the same locality 

 (probably no more than earlier examples of the same brood) ; these were 

 very smooth and nigrescent with a slightly paler central girdle, 1 1 mm. in 

 length and 4 mm. in breadth at their hardly explanate centre. From these 

 there emerged between the 20th May and 26th June following eighteen 

 examples of the ])resent species and, from three of the cocoons, nearly 

 thirty hyi)erparasitic Chalcids, some unnamcable Ptenmialiis\ the first ((^) 

 was emerged by 10 a.m. and the whole of the C,V/c//t"/rt'j immediately follow- 

 ing by the same hour on 20th-25th ; then came six males from the 22nd 

 May t(j 3rd June, mainly out in the morning by 10 a.m. though one 

 certainly emerged between 2 and g p.m. on 25th, and a second equally 

 certainly between 10 a.m. and 9 p.m. on 22nd; the last was extremely 

 active, with perfected wings and, when the box was opened the following 

 morning, at first attempted to conceal itself (which may account for the 

 rarity of Panisci during daytime), but after a short time it flew to the win- 

 dow curtains and there buzzed with great agility. Subsequently three 

 males and five females emerged thence to the i8th June; and the last 

 (9) was out by 10 a.m. on 26th ; one or more died as nymphs, doubtless 

 through artificial temperature. This is probably the species bred from 

 Eupithccia casliga/a (Entom. 1883, ]). 65) by Bignell in Devonshire.

Rufescent-testaceous. Head posteriorly explanate and distinctly a 

 little broader than eyes ; clypeus somewhat deeply discreted ; ocelli not 

 large, remote from the eyes which do not reach mandibular base; cheeks 

 subuccate and short, but distinct. Antennae quite or nearly as long as 

 body, black and basally pale with the second flagellar joint not or hardly 

 longer than scape. Mesonotum nilidulous and not very closely punctate, 

 with notauli not extending beyond centre ; metathorax short and trans- 

 aciculate with th-e transcarina not strong, though always laterally di.stinct. 

 Scutellum strongly carinate laterally to apex. Basal segment not elong- 

 ate, a little curved, apically subdilated, dorsally transconvex and centrally 

 sulcate ; petiole with basal lateral foveae black ; second segment a little 

 longer than apically broad, with epipleurae nigrescent. Femora some- 

 what stout ; hind tarsi not stramineous, rarely infuscate. Wings hyaline 

 with stigma stramineous or pale testaceous, emitting radius from its 

 centre ; lower basal nervure oblique and stronglv postfurcal. Length, 

 8-13 mm. 



There can be no doubt that P. dilatatus is the species described by 

 Holmgren, for it is the only one of this group to which his "capite sub- 

 buccato pone oculos " will apply ; and in this respect differs from all its 

 allies, except P. ccphalnhs which has stout metanotal transcarina and 

 larger head. 



Sweden in July (Holmgr. and Thorns.) ; almost unknown elsewhere — 

 though Brischke claims to have bred it in Prussia from pupae oi Peucania 

 obsokia and Anarta myiiilli — but not rare with us. I have it from the
