112 BRITISH ICHNEUMONS. \Casinaria 



the t3'pe form of whicli Tlionison found to be specifically distinct from 

 the first variety, which is the form described by Hohiigren and differs 

 primarily in having pale and not black mandibles and tegulae; since I 

 have seen none from Britain with infuscate mouth or tegulae I have ex- 

 cluded C. tcnui-,\'iitris from our fauna and substituted Thomson's species, 

 which agrees with (iravenhorst's in the pedal colouration and apically 

 hardly dilated abdomen, though with both mouth and tegulae pale, apical 

 radial abscissa longer, nervellus vertical and not geniculate, mesopleurae 

 subcoriaceous, trochanters and hind trochanterellus flavidous, var}'ing 

 occasionally in having the second to fourth segments basally rufescent on 

 either side or with more or less interrupted red fasciae and (xar. ///csozos/a, 

 Hlg.) the scape pale beneath. 



This is by far our commonest species of the genus, though by no means 

 abundant; on the Continent it is widely distributed through France, 

 Germany, Bruxelles in July, and Sweden in both July and August. I 

 possess several from Shere (Capron), Tostock in Suffolk on 17th Septem- 

 ber, 1898 (Tuck), Greenings in July (Saunders), Govilon in south \Vales 

 (Marshall), Harting in Sussex, September (Beaumont) ; it has been bred 

 at Dorking from Hypena proboscidalis on 27th May, 1901, by Prideaux, 

 and in the New Forest from Hemiihea strigafa in 1905 by Blair, as well as 

 from micertain hosts in Hampshire bv Gorham ; in West Kent during 

 May from larvae of CucuUia gnaphalii by Mrs. Holmes ; and on 8th 

 August, 1902, Dr. Chapman sent me a female bred from Plonca inftrsti- 

 iialis at Bejar in Spain. It has occurred to me sparingly in the Devil's 

 Ditch near Swaffham Prior in Cambs on loth June, 1902, in a Ryde 

 garden in September and (dead) in October, and at Setley in the New 

 Forest on 1 2th July. 



Probably the specimens of C. tcmii7\iilris bred b)' Bignell on 20th May, 

 and by Butler from Hcmithca thymiaria (Kntom. 1881, p. 140), and by the 

 former in Devon from H. progcinmaria on 2nd July (Entom. 1885, p. 104), 

 belong here ; though those from Ephyria pundana (Giraud, 1877), 

 Amphydasis httularia (Gravenhorst), Picris rapac (DT.) and that of tlie 

 synonymous Campoplcx conicus from Bonibyx dispai (Ratz. i. 95), should 

 be referred to Gravenhorst's species, which Thomson also calls C.la/ifrons, 

 Holmgr. On 27th May, 19 10, I found a cocoon on a hawthorn leaf in 

 my Monk's Soham garden from which a female emerged early in the 

 following month and was dead on 23rd.

Head very little narrowed behind the eyes, with vertex somewhat 

 broad; frons with a central longitudinal carina beyond the apical ocellus; 

 cheeks not short, usually subconstricted, with their costa nearly continu- 

 ous and slightly inflexed; mandibles not elongate, somewhat stout and 

 but little narrowed apically, with the lower margin subreflexed near its 

 base. Antennae somewhat stout and apically attenuate, with scape 

 entirely black. Thorax gibbous ; pronotal angles usually striolate. meso- 

 sternum subtransverse; metathorax with petiolar area broadly excavate, 

 the dentiparal areae narrow and rarely entire ; areola transverse, with its 

 basal area very short, transverse or quadrate. Abdomen broad and
