ROEBUCK : ON YORKSHIRE ICHNEUMONID^, 



37 



Rev. T. A. Marshall's 



" Yorkshire " 



List. 



receive the ichneumons (in any stage) which Yorkshire lepi- 

 dopterists breed. 



The nomenclature of the following species is according to 

 Marshall's Catalogue. 



ICHNEUMONIDES. 



Ichneumon bilineatus, Gmel. 



I. trilineatus, Gmel. 



I. vaginatorius, L. 



I. xanthorius, Fdrst. 



I. confusorius, Gr. 



I. luctatorius, L. 



I. latrator, Fab. 



I. quadrialbatus, Gr. 



Amblyteles armatorius, (Fdrst.) 



A. amatorius, (Milll.) 



Trogus lutorius, (Fab.)=Trogus Atropos. A specimen in 

 Mr. Robert Cook's collection, labelled Trogus Atropos, was bred 

 by him from a Yorkshire example of Acheronfza Atropos. 



T. exaltatorius, (Fanz.) Mr. S. D. Bairstow tells me 

 that two or three years ago he bred this out of larvse of 

 Smerinthus ocellatus, from eggs laid by a female which he took at 

 Askern Spa. A specimen bred out of the same insect, by Mr. 

 George C. Dennis of York, had the thighs of the legs very much 

 lighter in color than in Mr. Bairstow's specimen. 



Perhaps only a var. of T. lutorius L. (P. Snellen van 

 Vollenhoven). If a distinct species, would appear to be new to 

 Britain, as the name is not in Marshall's Catalogue. 



Dicselotus pumilus, (Gr.) 

 D. pusillator, (Gr.) 

 Phseogenes semivulpinus, (Gr.) 

 P. planifrons, Wesm. 

 P. stimulator, (Gr.) 

 P. ischiomelinus, (Gr.) 



CRYPTIDES. 



Stilpnus gagates, Gr.
