X. Some additions to Mr. Marshall's Catalogue of British 
Ichneumonide. By Jonn B. Brinemay. 
[Read April 6th, 1881.] 
At the earnest request of Mr. E. A. Fitch several of our 
leading lepidopterists have kindly saved from destruction 
such Ichneumons as they unfortunately have reared, and 
since many rare or local Lepidoptera have been bred, as 
a natural consequence some good species of Ichneumons 
also have been bred and preserved which otherwise 
would have been lost. At the same time many of the 
commoner Ichneumons have occurred; still, in very 
many instances, the host has been identified, which will 
materially increase our knowledge of their economy. 
Many of these specimens have been sent to me for 
examination, through the kindness of Mr. Fitch, and 
rarely indeed was a box examined that did not contain 
some addition to our fauna. Most frequently these were 
continental species, but occasionally a form presented 
itself of which I could find no description—notably three 
species of Limneria, all of which are very decided in 
colour and structure; I have searched in vain through 
Gravenhorst, Ratzeburg, Holmgren, Brischke, and 
Tschek. As these were reared from scarce Lepi- 
doptera (Oxyptilus teucrii, Nola albulalis, and Elachista 
monticolella), it is very probable they may be new species. 
Several of Foerster’s species of Pezomachus are also 
added, which I detected amongst a large number of 
specimens mostly captured by Mr. T. R. Billups, who 
has been very successful in taking these little apterous 
Ichneumons ; some of these, however, I had already taken 
in this neighbourhood. 
Several species of IJchnewmones pneustici are also 
included, as well as two more of Wesmael’s genera 
of the same subfamily (Oiorhinus and .dthecerus) ; these 
were captured by beating into an umbrella just before 
dusk towards the end of summer and autumn. 
It is with great diffidence that I venture to describe 
and name those insects of which I was unable to find 
any previous description, for the literature pertaining to
