282 BRITISH ICHNEUMONS. \_HniicospiiiiS 



in Dorset in July (Bankes); and on 13th September, 1908, Clutten sent 

 one of its cocoons which had just emerged from Agio/is praecox from St. 

 Anncs, whence the imago appeared the next year. It would seem 

 commoner on the coast sand-hills and salt-marshes than inland.

Testaceous, with two corneous alar marks and the anus at most slightly 

 subinfuscate. Length, 16-23 mm. 



So like the last species that I consider it distinct from habit rather 

 than conviction ; the sole distinction is that the anus is not determinately 

 black. Thomson says the cheeks are shorter and less constricted, which 

 I fail to find in my seventy examples of the two kinds ; Schm. remarks 

 that the body is as a rule stouter with the antennae longer, which is not 

 evident. 



A common species throughout Europe and frequently bred : from 

 Simyra mrvosa by INIocsary, Trachea piniperda by Ratz., Diantlucia irregu- 

 laris by Brischke, D. alhiinaciila by Mocsary, Hecalera dysodea by Ferris, 

 teste (jiraud, Cuciillia argcntca by Brischke, C. chrysanthemihy Alocsary, 

 Granimodes a/gira and Psciidophia tirrhaca b\- Kriechbaumer, and doubt- 

 fully from Sainia caropia by Tasch.; Dours' record from Lophynis pini is 

 doubtless an error. 1 have not found it quite so widely spread in Britain 

 as the last species (or form), with which it occurred freely in the salt 

 marshes and adjacent beach at Southwold during the first half of Septem- 

 ber, 1907; numbers were seen flying about the marram and other grasses 

 and easily captured in one's fingers; ii also came to light in the town at 

 midnight on 24th and 31st July, 1900. I have a long series bred at Bury 

 St. Edmunds and Tuddenham from Diaulhccia irregularis, with two females 

 raised during 1902 from Anticlca sinuala at the latter locality by Tuck, 

 who sent me a female from Tostock Fen on 8th September, 1900, with 

 the note: "I am certain that this Ophion stung me rather severely." It 

 has been bred in Devon on 25th July and 3rd August by Bignell from 

 Hccaic7-a serena and by Norgate at Norwich from Trachea piniperda, teste 

 Bridg.; I have it from Felden (Piffard); Shere (Capron); Deal, August, 

 1890 (Porritt); Brockenhurst, August (Cross); Tooting, Surrey (Sparke) ; 

 Clevedon near Bristol (Charbonnier) ; Bonhill 6th July and Barr in Ayr- 

 shire (Dalglish); but the only June capture was effected by Elliott, who 

 took it on the 19th in Tuddenham Fen.

Testaceous. Head anteriorly more or less broadly flavidous. Thorax 

 at least beneath nigrescent, if also discally the apex of metathorax and 

 sutures, frenum and scutellum are usually testaceous. Abdomen with
