110 Eev. T. A. Marshall's monograph of 



Described from 11 females in Fitch's collection, mostly 

 taken by him at Maldon in June and July ; three marked 

 " Huddersfield " were bred by Porritt, but it is not stated 

 from what larva : three females sent to Bridgman by W. 

 H. B. Fletcher were found in old birds'-nests containing 

 several different insects. 



Obs. Nees v. Esenbeck has referred to this species 

 the Bracon cis of Bouche, bred from the larvae of Cis 

 boleti, Scop. (Mon., ii., 399) ; but the small size of the 

 beetle renders this impossible. See M. profligator, Hal., 

 sp. 26, infra.
