162 THE ENTOMOLOGIST. 



three years I have searched in vain for it: I am at a loss to 

 account for its sudden disappearance. Latterly cows have 

 been turned into the meadow. Is it possible that they have 

 destroyed the pupoe ? — Joseph Anderson, jun. ; Alresford, 

 Hants. 



Variety of Pieris Rapce (Entom. vii. 140). — The yellow 

 variety of P. RapsB is far from uncommon ; I take it frequently 

 here. I think myself it is a food variation, due to the larvae 

 having fed on turnips, as almost all the specimens I have 

 were found flying over turnip-fields. I have, however, never 

 taken it except in the autumn. — fV. Douglas Robinson- 

 Douglas; Orchardion, Castle Douglas, June 12, 1874. 



Pieris Napi. — Early in May I took a pretty specimen of 

 P. Napi, with under hind wings of a clear yellow, and having 

 a pale orange costa. — Id. 



Is Saturnia Carpini Douhle-hrooded ? — I see Mr. Oldfield 

 (Entom. vii. 139) enquires as to the double-broodedness of 

 Saturnia Carpini. Like Mr. Oldfield, from eggs deposited in 

 April by this species, I have now young larvae feeding 

 on whitethorn, and now just changing their skin for the first 

 time. The " verticillate" arrangement of the hairs is well 

 seen in these young larvae, which at this age closely resemble 

 those of the various Eastern and North American species of 

 Saturnia, Attacus, &c., in the same stage. As bearing on the 

 possible double-broodedness of Carpini, I may state that 

 from larvae of Saturnia Pernyi, a Chinese species, hatched in 

 May and spun up the beginning of August, I have had moths 

 emerge both in September and also in the summer of the 

 next year. — W. A. Forbes; 35, South Castle Street, Edin- 

 burgh, June 4, 1874. 



[I have omitted Mr. Forbes' reference to Humphreys, con- 

 fessedly obtained from Haworth, and Haworth confessedly 

 from Fabricius, and his probably from some earlier authority. 

 I imagine Mr. Oldfield's object, and certainly mine, was to 

 get out of this copying groove, and to ascertain what was the 

 result of recent observation, — the observation of living ento- 

 mologists. I admit this would involve a complete revolution 

 in Entomology, and 1 think the sooner it comes the better. — 

 Edward Newman.] 



Acronycta Alni at Doncasler. — In 1872 I had the pleasure 

 to communicate to you the capture of a specimen of
