BRITISH ICHNEUMONS. 



\Phohocampa 



broad petiolar area, not strongly constricted face, whitish hind tarsi and 

 by the abdominal colouration. 



It would appear commoner with us than upon the Continent ; Sweden 

 and Germany (Thorns.), France (Gaulle) and in Belgium during April and 

 June (Tosq.). A cocoon I possess is, as described by Gravenhorst, pale 

 grey with both extremities black, preceded by a circle of often obsolete 

 large black spots or irregular lines, and measures 5^X3^ mm.; those of 

 the male are said to be smaller and darker than of the female by Brischke, 

 who (/.c.) bred it from Eiipithecia exiguaria, E. satyraria and E. actaearia 

 in Prussia. With us it has been raised from Lif?iacodes aselliis, Acronycta 

 alni, A.psi and captured at Earlham near Norwich (Trans. Norf. Soc. 1894, 



p. 620) ; bred in Devon on loth August from a half-grown larva of Dicra- 

 ntira vifiii/a (Bignell, Entom. 1883, p. 66 e/ Devon. Assoc. 1898, p. 491). 

 It is not rare with us and I have a series from Shere in Surrey, Felden in 

 Herts, Ely in Cambs.; Gosfield in Essex, where I swept a female on 14th 

 May, 1902; Bentley Woods and Assington Thicks in Suffolk, where both 

 sexes occur sparingly on birch undergrowth in the middle of May. Mason 

 has given me a female bred on ist April, 1905, from a larva of Drepana 

 fakataria at Market Rasen in Lines; and another emerged as early as 

 7th March, 1904, from an unknown host in my boxes. I swept the 

 cocoon from herbage in June, 1901, and took the dead and perfect 

 imago from it during the following December; Lyle has bred it from a 

 similar cocoon out of Cheiviatobia briniiata, and tells me that Mesochorus 

 co7ifusus is parasitic upon it, in the New Forest.
