144 Mr. J. B. Bridgman on some additions to 
the parasitic Hymenoptera is so scattered that it is not 
easy to know when all the descriptions have been 
examined, and more especially for one living so far from 
London, and unable in consequence to avail himself of 
the splendid libraries of the different learned societies. 
Iam deeply indebted to Mr. Fitch, who kindly sent me 
any books or papers which he thought would be of use, 
or that I required. I need not say how much we are 
obliged to Messrs. C. G. Barrett, J. Sang, G. Elisha, 
P. Cameron, E. A. Butler, G. C. Bignell, V. R. Perkins, 
T. R. Billups, the late W. P. Weston, and others for the 
assistance they have rendered in sending these insects. 
Mr. Cameron has lately sent me about a thousand 
specimens of his Scotch Ichneumons to examine, and, 
when I have had time to get through them, many species 
new to our fauna will most probably be found amongst 
them. In this paper reference is made to those species 
which have been previously noticed, but have occurred

Females of what I believe to belong to these two 
species I detected amongst Mr. Cameron’s Ichneumons. 
ICHNEUMONIDES AMBLYPYGI. 
Amblyteles flavocinctus, Desy. 
As I have had an opportunity of examining this hand- 
some insect, which does not appear to be known on 
the Continent, I have added a fuller description of the
