Cnmasfus'] BRITISH ICHNEUMONS. 57 



on July iQth, igoo, at Bournemouth in Hants and several of both sexes 

 between 26th June and 8th July, 1905, from cases collected at the same 

 locality on third of the former month ; two more females emerged from 

 three cases of the same host, which contained nothing but the host's 

 larval skin and this parasite's cylindrical black cocoon with a white 

 central cincture, taken by Mrs. Cowl in Dorset, on 19th July, 1899 — the 

 remaining cocoon contained on 14th March following a dead P.ur/ic larva 

 and a dead parasitic larva, which failed to attain maturity ; I also possess 

 half-a-dozen examples bred by Barrett from British specimens of this 

 host. Beaumont took a long series at Kilmore in Ireland between 13th 

 and 27th August, 1898 ; but it is certainlv rarely seen on the wing, since 

 Miss Chawner found but a single female in the New Forest and one male 

 occurred to me on 24th August, 1905, in the marshes at Brandon in 

 Suffolk. Rev. T. A. I\Iarshall has recorded (E.M.M. 1866, iii. p. 02) his 

 capture of manv specimens of this "rare" species at Freshwater Bay in 

 Pembrokeshire.

This species agrees with the last in having the clypeus twice broader 

 than long and its apex both callose and subtruncate, with the anterior 

 tibiae apicallv constricted. But it is a little smaller and stouter, with the 

 second segment of 9 only apicallv castaneous, the stigma is distinctly 

 narrower, the submarginal nervure shorter and the radial emitted further 

 beyond the centre of the stigma. 



In both sexes the orbits are rufescent tlavous, the mandibles except 

 their teeth and as a rule the clypeus are flavous ; the front coxae and tro- 

 chanters are more or less broadly piceous, the hind femora are not always 

 piceous nor their tibiae basally infuscate. The stigma of the hjaline 

 wings is piceous and their tegulae flavidous. Length, 8 mm. 



Germany (Grav,), France ((iaulle) bred from a caterpillar on Camomilla 

 (Giraud), Belgium in August (Tosquinet), Austria (Kirchner) and Sweden 

 (Thomson). Fitch records this s])(H-ies as reared by M'Rae from Psyche 

 viUosella (Kntom. 1881, p. i+'i) ; inil it was at that time considered syn- 

 onymous with the last and certainlv needs furtlier confirmation as British, 

 since tlie (^nly example I possess is a female, bred bv Dr. Chapman, witli 

 Ischnus /iinidarum, Ci'w. and /.iiiiiiir/i, during 11)05 troni /''iiiiini cas/a 'at
