CARABUS NITENS IN SWALEDALE. 



CREPUSCULARIA (SPHINGID.^). 



Sphinx ligustri. Deilephila celerio. 



Sphinx convolvuli. Smerinthus ocellatus. 



Sphinx pinastri. Smerinthus populi. 



Deilephila galii. Smerinthus tilioe. 



Deilephila euphorbice. Acherontia atropos. 



Deilephila elpenor. Macroglossa stellatarum. 



Deilephila porcellus. Zygaena minos. 



Among the Bombycidse we must notice the singular melanism 

 of Spiloso7na lubricipeda named zati7na Cramer (radiata Steph.), 

 almost exclusively peculiar to Heligoland. Mr. Gatke has raised 

 a point which proves, by the variation of examples, that it is a 

 variety and not a distinct species. It is met with, but very rarely, in 

 Holland and on the east coast of England. 



The list of butterflies is composed chiefly of species which 

 exist in Southern Norway, to which may be added some others 

 which are found in Germany. 



In reply to some questions I asked Mr. Gatke in reference to 

 migratory Lepidoptera, he writes me : — ' I can assure you that my 

 cases only contain those that I have obtained here, the greatest part 

 taken by my own hands. The specimens were often very faded and 

 ragged, and in those instances I procured good specimens from the 

 Continent, which I have placed side by side with those caught here. 



' Those I was not able to identify I sent to friends good enough 

 to determine them for me. Such was the case with Meiifcea didyma 

 (whose appearance so much surprised you, also its freshness), and 

 which has been determined on good authority. 



' Of Deilephila celerio I took one very fresh example. I took 

 twice in my own garden the pretty little nacreous white Pyrahd, 

 which I was told is the Margarodes unionalis Hiibn., and the habitat 

 of which is the South of France.' 



The information given by Mr. Gatke, sincere and frank as is 

 everything he writes, shows that if there is any error in this list, it 

 must not be attributed to him.' This concludes the remarks. I am 

 aware that anything connected with the migration of insects at 

 Heligoland must be of considerable interest to English entomologists, 

 and, as there are doubtless many who have not seen, or who would 

 not be able to obtain a copy of M. de Selys-Longch amps' paper, 

 I have ventured to give an English translation of ,it. 



NOTE—COLEOPTERA. 

 Carabus nitens in Swaledale. — On the 20th of May, a bright and sunny 

 day, while Mr. Roebuck and I were investigating the plateau on which, at an 

 altitude of 1,620 ft., Birkdale Tarn is situate, I found a couple of examples of 

 this handsome beetle. On the previous evening we noticed C. violacetis on a 

 mountain path near Keld. — W. Eagle Clarke, Leeds, May 22nd, 1888^^
