58 BRITISH ICHNEUMONS [Cirmas/us 



strongly trans-strigose. Scutellum black. Abdomen with lateral petiolar 

 sulci entire and a little curved ; the strongly elongate second segment 

 narrowly rufescent apically in 9 , apices of second and third segments 

 more broadly red in ^ ; terebra but slightly shorter than abdomen. Legs 

 red with coxae and trochanters black, the anterior apically flavous ; hind 

 tibiae and tarsi piceous with the former except at both extremities extern- 

 alty pure white ; ^ with anterior tibiae flavous and the hind femora 

 sometimes infuscate. Wings with the stigma piceous, basally pale and 

 not broad ; tegulae pale stramineous ; radius subsinuate and emitted far 

 beyond centre of stigma. Length, 8-10 mm. 



This and the next species are distinct from the remainder of the genus 

 in the entire and subcurved lateral petiolar sulci ; not broad stigma, 

 emitting radius far beyond its centre ; in the entire areola and trans- 

 rugose petiolar area, the long pale cheeks and anteriorly triangular head. 

 The snow-white outer side of its hind tibiae renders the present a con- 

 spicuous species. 



Piedmont, France, Germany, Sweden, Belgium in June, and Austria. 

 It was given by Westwood in 184.0 as type of the genus, and he knew but 

 three British species ; it must be very rare with us, since the only record 

 is by Bignell, who captured it at Bolt Head in south Devon, during the 

 middle of June. Two females were taken on Clare Island, Co. Mayo, in 

 September, iqio, by Rev. W. F. Johnson (recorded by me under the 

 name C. albipe7inis, Zttt., in Proc. R. Irish Acad, igii, No. 24, p. 15). 

 The only other specimens I have seen are a female, of the form described 

 by Thomson with short terebra, which was in a rabbit's hole on the open 

 heath on iith June, 1908, near Brandon in Suffolk, and a male swept a 

 mile or so away at Lakenheath just nine years earlier. I have also exam- 

 ined a beautiful male captured during September, 19 10, at Kings Lynn by 

 Atmore. 



4. pungens, Grav. 



Creniastiis pungens, Gr. I.E. iii. 745, <? ? ; Thorns. O.E. xiv. 1453. ? . (?) Pori- 

 zon alhipeniiis, Zett. I.L. 396, <f ; Crcmastiis albipennis, Holmgr. Sv. Ak. 

 Handl. 1858, p. lO'J. i 9 . 



Head with the clypeus apically a little elevated ; orbits, mandibles 

 except apically, and sometimes the clypeus, rufescent. Thorax immacu- 

 late black, with the areola circumcarinate. Abdomen Avith lateral petiolar 

 sulci entire ; segments two and three apically rufescent ; terebra longer 

 than half abdomen. Legs red with anterior tibiae not apically constricted ; 

 all flic coxae and trochanters, except sometimes front ones, mainly black; 

 hind legs subinfuscate. Wings with stigma piceous and tegulae })ale 

 flavous. Length, 8-9 mm. 



This species was easily distinguished from the last by Thomson by the 

 subelevated clypeal apex and longer terebra, but (Jravcnhorst terms that 

 of the former species only abdomine paulo brevior and of the latter 

 sometimes dimidio abdomine longior. Schm. thinks the hind pedal 

 colour their only difference. 



It is probable that it was Holmgren's and not (iravenhorst's species 

 that Marshall regarded as British, since the latter is given by him as no 

 more than a doubtful synonym, and it was not known to Desvignes in 

 1856.
