88 THE ENTOMOLOGIST, 



department of the British-Museum collection! — JV. Mac- 

 millan ; Castle Canj, Somerset. 



There is a second collection of moths and butterflies not 

 generally exhibited, but which may be seen on application to 

 the proper authorities. 



Thecla BetiilcB taken at Night. — On October 2nd, 1871, 

 I took a specimen of the brown hairstreak, Thecla Betulae, at 

 night, on a blackberry bush. Is not this an unusual 

 occurrence ? — Waldegrave ; Bookhani Lodge, Cohham, 

 Surrey. 



I do not recollect a previous instance of Thecla Betulae 

 having been taken by night; but it does not appear to me 

 extraordinary that it should be taken by night at rest: had 

 it been flying it would have been more remarkable. I have 

 recorded more than one instance of Antiopa being taken 

 flying by night. 



Polychloros Larvce feeding on Nettle. — In the spring of 

 last year I took the larvae of what I considered V. Urticae, 

 feeding on nettles, and from time to time added other larvae 

 of Urticae in the same breeding-cage kept for nettle-feeders 

 only ; and, to my surprise, a number of imagos resemble 

 Polychloros in colour and marking, keeping the size of 

 Urticae. I submit them to you for your remarks. There was 

 no apparent difference in the larvae that I observed while 

 feeding.— Ja..<f. A. Tawell ; EarVs Colne, March 11, 1872. 



These specimens have a wonderful similarity to Urticae, 

 which they do not at all exceed in size ; still the colour is 

 nearer to that of Polychloros than that of Urticae ; and the 

 black spot at the anal angle of the fore wing is present, as in 

 Polychloros; the white spot on the costa of Urticae is 

 absent, also as in Polychloros. 



White Variety of Phlceas. — Some time since I captured a 

 specimen of Phlaeas (small copper), in which the copper 

 ground colour of the wings is entirely replaced by white. Is 

 this variety an unusual one, or has it been noticed before ? 

 ^E. H. Allis; Bristol, March 22, 1872. 



"There is a variety of this species in which the parts 

 which are usually copper-coloured are of a pure and brilliant 

 white." (Newman's ' I3ritish Butterflies,' p. 115.)
