﻿60 THE ENTOMOLOGIST. 



The language of the Canton Vallais, where Visp lies, is 

 German, but as it adjoins a French canton many of the people 

 speak that language also. Kane's ' Handbook of European 

 Butterflies ' will be found a most useful vads mecum.

ON THE VARIATION OF HELIOPHOBUS H1SPIDUS AT 



PORTLAND. 

 By N. M. Richardson, B.A. 



I think that I can give an explanation of the confusion tbat 

 has arisen with regard to the violet tinge of Heliophobus his- 

 pidas at Portland. I sent to Mr. Tutt on Oct. 1st, 1888, speci- 

 mens taken during September, and on Oct. 15th answered a 

 letter of his asking about the violet tinge. It is probably a part 

 of this letter that he quotes (Entom. xxii. 136), and so far as I 

 remember I had not at that time noticed any distinct violet 

 tinge. 



This year I found that many specimens, when alive and for 

 some time after death, were distinctly tinged with violet, or 

 perhaps more accurately pinkish-lilac, but tbat after a few weeks 

 this tinge entirely disappeared. At the present time, though I 

 kept for myself several strongly tinged specimens, I cannot find 

 a trace of this violet tinge in any of them. 



Hiibner therefore probably figured the moth alive or when very 

 recently killed. I could not, however, say of any of the Portland 

 specimens, even during life, that their " pale markings were of a 

 delicate violet " ; on the contrary, they are very pale ochreous, 

 some of them being almost white : the violet is nothing more 

 than a tinge, far less intense than the pink colour of a fresh 

 specimen of Xylocampa lithoriza, and is, as I have said above, 

 very evanescent. It is spread over the whole of the fore wings, 

 but is most striking on the hind margin and fringes.
