274 BRITISH ICHNEUMONS. \i)phmt 



has occurred to luc on the open, wind-swept lieatli beneath stones and at 

 roots of Senccio jacohcac. In my Monks Soham garden it flies in the 

 August sunshine, occasionally alighting on whitethorn hedges and 1 have 

 once bred it here from a Noctuid chrysalis; early in September, 1902, it 

 was hovering among bracken at Foxhall, and !\Iusham has bred it at 

 Lincoln. It has frequently been raised from Lepidoptera: from Mamestra 

 brassicae in a Methley garden near Leeds by Wiggin in 1899, and others 

 emerged from the same locality at 1 1 a.m. on 2nd and 2 p.m. on 3rd June, 

 1900, which were received the preceding November; one sent by Cross 

 from Ely was out with dry wings at 10 a.m. on 14th May, 1901, and 

 another at the same hour on 19th May, 1902, from a Noctuid pupa. At 

 the end of 1901, Clutten sent from Burnley a batch of eight cocoons 

 from Hadetia pisi diwdi Dianthaecia capsincola, which emerged between the 

 ist June and i ith July, 1902, showing that similar temperature, etc., does 

 not cause these insects to emerge simultaneously ; though two of a brood 

 of three emerged on 21st and 22nd April, 1902, from their own cocoons, 

 within the cocoons of Orfhosia lo/a dug from the sand at Blackpool, 

 which had not been permitted by the parasites to pupate. These last 

 emerged during the daytime and early morning; and in 19 10 Mr. Clutten 

 kindly sent a further batch of three from the same host at St. Annes, 

 which emerged between the 6th and 12th May following. On ist August, 

 1907, he sent me a couple from Doncaster Cosinia irapczina, which 

 emerged on 12th and 15th May, 1908. It is wide- spread through Sweden, 

 Kurland, France and Belgium; but it has been neither bred nor prev- 

 iously noted in Britain. 



11. brevicornis, sp.n. 



Among the numerous examples in my collection of the last species 

 is a pair which I propose to consider distinct solely on account of the 

 remarkable antennal brevity; those of the 9 extend hardly beyond the 

 metathoracic apex, while the $ flagellum reaches only to the apex of the 

 postpetiole. The 9 antennae are subfiliform and testaceous, those of 

 the $ are apically attenuate and subinfuscate. The scutellum is not 

 margined, nor are the basal segments constricted. Length, 13-14 mm. 



The type of this -sufficiently distinct species was captured by Mr. E. W; 

 Flatten in the Bentley Woods near Ipswich in Suffolk on 2nd June, 1899. 

 A male was presented to me by the late Mr. E. G. J. Sparke, i^.A., f.e.s., 

 who took it in Surrey during the summer of 1900.
