Family BRACONIDyF. 



British species 439, distributed into 125 genera, as enumerated 

 by the Rev. T. A. Marshall in his Catalogue, published in 1872. 

 Like that of the allied groups, the literature is much scattered; 

 the principal authorities being Forster (for the genera his 

 'Synopsis d. Familien und Gattungen d. Braconen/ Bonn, 

 1863); Nees ab Esenbeck (' Hymenopterorum Ichneumonibus 

 aflfinium monographice,' 2 vols., 1834); Wesmael (' Monographic 

 des Braconides de Belgique,' 1835-7; and other works); Ratzeburg 

 (Die Ichneumonen d. Forstinsekten, 1844-52); Haliday; Ruthe; 

 Bouche; Curtis, &:c. The Rev. T. A. Marshall gives a useful 

 article in Ent. Ann. 1874, referred to in connection with 

 Ichneumonidas : a table of Braconid^ and their hosts is given at 

 p. 125; and at p. 144 is a list of 8 British species worthy of 

 special mention. 



The remarks on collection and preservation made under the 

 head of IchneumonidEe apply equally to the present family. For 

 the following names of Yorkshire species I am indebted to the 

 Rev. T. A. Marshall (see remarks under "Ichneumonid^e," p. 36).
