XVII. Further additions to the Rev. T. A. Marshall's 

 Catalogue of British Ichneumonidae. By John B. 

 Bridgman, F.L.S. 



[Bead July 3rd, 1889.J 



The increasing interest taken by British lepidopterists 

 in the parasites they may unfortunately breed is shown 

 by the length of these papers of additions to the British 

 list. Ichneumons new to Britain or Science are con- 

 tinually being sent to me. I have already sufficient 

 material for another paper had I but the time to work it 

 out. Since my last paper hymenopterists have sustained 

 a severe loss by the death of A. E. Holmgren, the 

 eminent Swedish entomologist, one who perhaps has 

 done more for the portion of Hymenoptera he studied 

 than any previous author. Gravenhorst, in his three 

 volumes of ' Ichneumonologia Europese,' while he accu- 

 rately described an enormous host of ichneumons, gave 

 far too little description of structure. This defect was 

 greatly remedied by the numerous papers of Wesmael, 

 principally as far as the family of Ichneumon was con- 

 cerned. A. E. Holmgren still further improved on the 

 very excellent work done by Wesmael, when he pub- 

 lished the first two parts of ' Ichneumonologia Suecica ' ; 

 the third part, which was to have contained the 

 Ichneumones Pneustici, has not been pubhshed, and I 

 fear never will now ; he was engaged on it at the time of 

 his death. I received a letter from him the end of last 

 November, asking to borrow the new species I had 

 described. Besides these monographs he published 

 monographs of the Swedish Ophionides, Tryphonides, 

 Pimplides, and of the genus Campoplcx, wdth good clear 

 descriptions both of structure and colour, the former of 

 which was very much needed ; the Cryptides was the 

 only family he had not monographed. Besides these 

 he wrote several papers in various magazines ; the date 

 of his first paper is given in ' Literatura Hymenopter- 



TRANS. ENT. SOC. LOND. 1889. — PART III. (oCT.)
