274 MR. CLAUDE MORLEY ON ICHNEUMON MANIFESTATOE. 



Three interesting questions present themselves : Was Marsham's insect 

 Epliialtes extensor, Tasch.^ now for the first time recorded as British ? has it 

 existed and propagated in Kensington Gardens ever since it was mentioned as 

 found there so long ago ? and, supposing Ichneumon manifestator, Msh. (nee 

 Linn.) to be Epliialtes extensor, Tasch., have we determined whether it has 

 predilections for a hymenopterous, coleopterous, or lepidopterous diet? 

 Taschenberg* quotes Panzer as the author o£ his species^ but Ichneumon 

 extensorius, Panz. f, is regarded by Dalla Torre J as a synonym of Ichneumon 

 primatorius, Forster §, belonging to a very different group of insects. As 

 regards its Continental hosts, nothing at all reliable can be stated, since none 

 have yet been instanced for the actual species ; but two insects described under 

 the allied genus Pimpla hy Ratzeburg || have been doubtfully synonymized 

 with it^f, and these were originally bred from, respectively, Cynips (Biorrhiza) 

 terminalis (aptera, Bosc) and Tortrix [Grapholitha) dorsana, Rtz. {pactolana, 

 Zll.) ; but these very hosts are so dissimilar as to render the synonymy 

 extremely doubtful.

 in regarding (op. cit. iii. p. 447) Epliialtes extensor, Tascli., as synonymous with Pimpla 

 rohorator, Fab. ; and consequently the hosts he irives are valueless.
