place on March Gth ; the eggs did not hatch, the temperature 

 being too low when the pairing took place. Two other pairings 

 only took place, June 8rd and June 6th ; but, as I have mentioned 

 above, six female Roylei paired with six male Pernyi. 



Attacus Atlas (Himalaya race). — Eighty cocoons. Eight 

 moths only emerged from July 31st to September 30th. The 

 cocoons left are in perfect condition, and they will keep till next 

 summer. 



Actias Selene. — Sixty cocoons. Moths began to emerge on 

 March 12th, and continued to emerge till August 13th ; five 

 months to obtain the moths from all the cocoons. Only one 

 pairing was obtained ; it took place on June 30th. 



Samia Gloveri. — With about one hundred cocoons. Moths 

 emerged from May 15th till the end of June. Five pairings only. 



Telea Polyphemus. — With about sixty cocoons, only three 

 pairings were obtained. 



As I have stated, the final or practical result from the larvge 

 of silk-producing Bombyces reared this season in my garden here 

 has been most unsatisfactory, owing to the bad weather in 

 August ; but larvse of all the species reared have been preserved, 

 and specimens of them in various stages will be seen in the 

 Bethnal Green Museum.

ON THE SUPPOSED EXTINCTION OF VANESSA C-ALBUM. 

 By E. S. Hutchinson. 



" Vanessa C-album is undoubtedly becoming scarcer in Great 

 Britain, and is perhaps on the road to utter extinction." The 

 above is a quotation from a notice in the September number of 

 the 'Entomologist' (Entom. xiv. 210), from the pen of Mr. G. 

 Coverdale ; and as it winds up with a wish to learn if V. C-album 

 is " less common on the Continent or elsewhere," I hope he may 

 pardon a reply from Herefordshire, which is its great stronghold 

 in this kingdom, although it must differ widely from the views he 

 entertains. I am an old entomologist, and have lived in this 

 county and noted the habits of V. C-album for fifty years ; and I 

 can safely say I never remember the species so common in any
