﻿210 THE ENTOMOLOGIST. 



cannot find that I have ever recorded it in my various Conti- 

 nental tours, but even if I did I merely adopted Staudinger's 

 Catalogue as the best known list. Certainly I have never 

 considered the species critically, and I have not a specimen 

 of cBsculi of my own capture in my collection. It is very curious 

 that among a long series of var. cerri from Digne and other 

 French localities, I have not got a single specimen of cssculi. 

 So far as I am concerned I do not regard the cornnti as safe 

 characters. I referred to this matter at the Annual Meeting of 

 the Entomological Society. The armature of the vesica is very 

 minute, and very great caution is necessary in dealing with it ; 

 this, however, is rather intimated by Dr. Chapman. To make 

 the decision quite definite it will be necessary to do as Mr. 

 Kowland-Brown at first set out to do, viz. breed both insects 

 through as far as possible side by side so as to be able to make 

 the necessary comparative descriptions, and this I sincerely hope 

 he may do ere many years have past, and, at any rate, I am 

 grateful for his present investigations and article. 



THECLA MSCULl IN THE SOUTH OF FEANCE. 

 By H. Eowland-Beown, M.A., F.E.S. 



To the list of Departments {antea, p. 205) in which this 

 species is known to occur may be added Gard. Writing in the 

 ' Entomologist,' vol. xxxviii. (1905), p. 52, Dr. A. P. Rosa states 

 that he took specimens of a Theclid at Pont-du-Gard which, at 

 the time, he supposed to belong to T. acacics. In reply to my 

 enquiry he has kindly supplemented his note as follows : — 



" The five other specimens mentioned {loc. cit.) under T. 

 acacicB were cesculi, and the reason I did not state this was 

 because I could not at the time (nor now) reconcile myself to 

 the idea that they represented a variety of a species of which cerri 

 was a member. I reasoned that they could not be cbscuH, because 

 they were most evidently to me not a variety of ilicis (var. cerri). 



"I wrote to Mr. Tylecote . . . and pointed out to him the 

 difference between the two, and telling him that I believed they 

 represented different species. I enclose herewith his reply in 

 his own handwriting. Though it did not coincide with my 

 views, yet it showed that he agreed with me, and that I then 

 (1905) had the opinion which you have now expressed in your 

 article in the current ' Entomologist.' I give you the characters 

 on which I then based my distinctions between the two : —
