dull with no distinct areae, areola cariniform or obsolete, lateral carinae 
entire and spiracles circular. Abdomen. stout; basal segment stout,

A most conspicuous insect in its large size, pale colour and stout 
structure. 
It has been found in France, Hercynia in June, Prussia, Sweden and 
western Russia; it has been constantly bred from the large Cimbicid saw- 
flies, first by Ratzeburg in the Hartz Mountains from Cimbex Sorbi, con- 
sidered to be C. ducorum by Holmgren and Z7richiosoma betuleti by Dalla 
Torre; next from larvae and the cocoons of Clavellaria amerinae by

Giraud and Brischke, who describes its cocoon as “cylindrisch, diinnhau- 
tig, braun, aussen etwas wollig”; and to these Gaulle adds 7%ichiosoma 
vitellinae. In Britain it is by no means common, and hardly ever taken 
at large; Bignell bred it on 11th June, 1881, from 7Z7ichrosoma betuleti 
cocoon (Entom. 1885, p. 152; the genus is erroneously printed Blennocampa 
at Trans. Devon. Assoc. 1898, p. 235, copied by D. T. and Gaulle); four 
were bred at York from cocoons of the same species in 1880 (Wilson, 
Yorks. Nat. 1881, p. 153) and fourteen from the same host, found during 
the winter, emerged 1881 (Trans. Yorks. Nat. Union, 1882, p. 106); Nor- 
wich, several bred from this host, but not otherwise seen (Bridgman); a 
female from Rannoch (Gibbs). I possess some half-dozen, taken or bred
