80 THE ENTOMOLOGIST. 



its kind, since no more pupae emerged in the summer of 1887, 

 but all hybernated, I cannot avoid the suspicion, that an egg of 

 the ordinary napi might have possibly been introduced with the 

 food-plant, and invalidated the experiment. Kepetitions of the 

 experiment can alone make this certain. 



The rest of the pupge hybernated in an unheated room, after 

 they had been kept in the incubator until July 30th, and then in 

 a room, and emerged very irregularly in the spring of 1888, 

 between April 6th and June 2nd, 22 specimens in all, 13 females 

 and y males. All are completel}^ normal bryonies, with one 

 single exception. 



One female has, indeed, the usual brown-grey ground colour, 

 and also the usual marking of the female of this form, but this 

 colour is broken up or replaced by white in several places on the 

 hind wings, and in a few smaller ones on the fore wings. The 

 butte'fliy appears speckled and spotted with white, just as if it 

 had been wetted or sprinkled with white, and the blotches of 

 colour had flowed quite irregularly over the surface of the wings, 

 and had covered the brown-grey or dissolved it. I have never 

 seen such a colouring elsewhere, or found it described.

THE SYNONYMY OF THE BRITISH BEE HAWK-MOTHS. 

 By C. W. Dale, F.E.S. 



Mr. Kirby is perfectly right in stating that Linne's name of 

 faciformis belongs to the broad-bordered species. I believe all, 

 or nearly all, entomologists held that opinion up to the time of 

 Staudinger and Wocke's Catalogue, and it is well borne out by 

 reference to numerous figures. One exception is that of Moses 

 Harris, who figured tipulceformis for fuciformis. In my " History 

 of British Hawk Moths" ('British Naturalist'), I have not de- 

 parted from the old opinion. Scopoli, in 1763, three years 

 before Linne's 12th edition of the ' Systema Naturae,' gives 

 Sphinx fuciformis as *' In Lonicera, Scabiosa," confusing the two 

 species. His figure appertains to the narrow-bordered species, 

 but his description apparently belongs to the broad-bordered one. 

 De Villers, in 1789, also says oi fuciformis, " Hab. in Lonicera, 

 Scabiosa." It will be noted that Linne says, " Habitat in Loni- 

 cera" only. 



Now, as to S. tityrus being the specific name of the narrow- 

 bordered species, I can positively say the case is not proven. 

 Linne, in his 12th edition, gives tityrus as a variety of fuel- 

 formis, and as such we must believe it to be ; but as he makes 

 no reference to the wings having a broad or narrow border, and
