Campoplex] BRITISH ICHNEUMONS. 73 



cocoons he sent me were evacuated on otli of tin' folio\\in,t>- nionlli ; Prof. 

 Ima.^-e has given me a male, bred in 1003, " I think from hirva of A. caja, 

 certainly from an Arctia larva"; and Goodwin a female reared from larva 

 of Notodouta chaonia found in August, 1002, in Kent. On the wing it 

 appears scarce and I have not met with it, though Charbonnier took it at 

 Freshford near Bath in Septt'inbcr ; Capron captured one about Sh(>re in 

 Surrev; and Adams found it on i()lli of the same month in 1900 at Lynd- 

 hurst, where it has been bred by Miss Chawner. 



5. obliteratus, Ilolmgr. 



Campoplex obliteratus, Holragr. Bih. Sv. Ak. Handl. 1872, p. 59; Thorns 

 O.E. xi. 1060, 6 ? . 



A black species with the abdomen centrally and most of the legs pale 

 rufescent-flavous, the hind tibiae at tiieir apices and extreme base 

 infuscate ferrugineous and palpi sub-testaceous. It is extremely similar 

 to C. falcator though generally a little smaller with the hind femora 

 distinctly more broadly pale at their apices, the apices of their tibiae 

 conspicuously dark, the mesopleurae less strongly punctate with the striae 

 before the dull speculum much coarser but finer and more obsolete, the 

 dentiparal metathoracic carinae rather more determinate and the palpi 

 paler. Length, 12-16 mm. 



At once known by the hind pedal colouration. 



Sweden, east and west Gothland, Upland and Lapland (Holmgren), 

 north and central Europe (Thomson) ; but I know no records outside 

 Scandina\ia. In September, iqoo, Dr. Phillip ^Lason kindly gave me 

 two females, which were captured at Greenings in Surrey, near East 

 (irinstead, during June, 1871, by INI r, Wilson Saunders, but the sj)ecies has 

 not hitherto been noticed as British. Three males in my collection are 

 from Piffard's and Capron's collections, and the Campoplex recorded by 

 me in error as C. hiiuis, Forst. (E.ALM. 19 10, p. 39) from the Isle of Soay 

 by Skye.
