( 335 ) XIII. Further additions to the Rev. T. A. Marshall's Catalogue of British Iclmeumonidse. By John B. Bridqman, F.L.S. [Eeacl July 7tli, 1886.] Since the appearance of my last list of additions I liave examined a very large number of British Ichiieimionid(e, and, as might be expected from the very little attention which has been bestowed on this division of Entomology in this country, I have detected many species which have not hitherto been recorded as British ; while some have been met with which appear to me to be unde-scribed. Professor C. G. Thomson has very kindly examined many insects for me, principally Cryi)tidcs and the genus Mesochorus, and the result of his exami-nation I have in many instances recorded in this paper. I am very deeply indebted to Mr. W. H. B. Fletcher for the trouble he has taken in saving for me the parasites he has bred, which last year amounted to more than 1000, and, as in most instances the name of the host was added, much valuable information has been obtained. My thanks are also due to Messrs. Atmore, Bignell, Billups, Cross, Griffiths, Harwood, Porritt, and many others for insects kindly sent me. Ichneumon himaculatorius, Panz. I took a female of this handsome little ichneumon at Brundall, near Norwich, on September 17th, 1884. Trogus exaltatorius, Panz. I have a fine female of this Trogus, given to me by Mr. G. C. Bignell in 1882. It is very like lutorivs, but is larger, has the cloud at the apex of the wings more distinct, and different sculpture at the back part of the metathorax. TRANS. ENT. SOC.
