NOTES AND OBSERVATIONS. 155 



localities I believe birch is usually the chief food of this species. As 

 I have before stated, there is no authentic instance of either the 

 eggs, larvae, or pupae of V. antioim ever having been found in the 

 British Islands. From the large size, velvety black colour, and gre- 

 garious habits of the larvae, they would form a most conspicuous 

 object on the foliage of any tree ; it is obvious that if they existed 

 in this country they could hardly have escaped detection. — F. W. 

 Frohawk; March, 1911. 



Amphidasys betularia ah. doubledayaria in Essex. — My ex- 

 perience certainly endorses that of Mr. Mathew, given on page 67 

 of this year's ' Entomologist,' as to the comparative frequency of 

 the occurrence of doubledayaria in Essex. On June 9th, 1909, 1 bred 

 a normal female from a larva obtained in my garden at Westcliff- 

 on-Sea, on Michaelmas Daisy, the previous year. In the evening, 

 I hung her up in a gauze cage to a hme tree in the garden, and, 

 although it w^as a bad evening, she attracted three males. Of these, 

 two were typical, and one ab. doubledayaria. In the autumn of the 

 same year I took a number of larva3 off a climbing rose in the garden 

 of the Eectory at Leigh-on-Sea. From these I bred fifteen moths 

 during April and May, 1910, four being typical and eleven ab. double- 

 dayaria. Of course, this is a very limited experience, but, as far as it 

 goes, it tends to prove that in the Southend district ab. doubledayaria 

 is about as common as the typical form. — Alfred T. Stiff ; Leigh- 

 on-Sea, Essex, February 24th, 1911. 



Species new to the Gloucestershire List. — I find that I took 

 on June 20th, 1906, amongst the apple trees in my garden, a speci- 

 men of Argyresthia cornella (curvella), and on August 6th following 

 I found Cataplectica {Asychna) 'profugella — a local and uncommon 

 species— on the Cotswolds. On June 23rd, 1910, Argyresthia sorbiella 

 was found resting on a yew tree in the Forest of Dean. Oxyptilus 

 teucrii appeared on our hills on July 14th following, at dusk, amongst 

 Teucrium scorodoniaim, and Ephestia kuhniella was captured in my 

 house on August 26th and September 21st last. These species do 

 not appear to have been hitherto recorded from this county. I am 

 again indebted to Mr. Meyrick for his kindness in identifying the 

 specimens.— C. Granville Clutterbuck, F.E.S. ; Heathside, Heath- 

 ville Eoad, Gloucester, February 22nd, 1911. 



Wanted : living Vanessa polychloros. — Should any collector 

 capture a female Vanessa polychloros this spring and would kindly 

 send it alive direct to me, I should be greatly obliged and would 

 make a return. I am particularly anxious to obtain eggs of this 

 species. — F. W. Frohawk ; Eayleigh, Essex. 



Six Days at Glen Tilt, Perthshire. — It is a long time since 

 I have seen any notes in the ' Entomologist ' on the Lepidoptera of 

 the above district, or on collecting therein, so having spent six days 

 there in July last, 19th to 24th inclusive, I thought I would send 

 you a brief note of the species observed : — 



Erebia athiops. Plentiful whenever a gleam of sunshine appeared, 

 occurs over a great extent of the Glen in grassy places. — Boarmia 

 reixindata. Several on trunks of fir trees, a greyish form and some-_
