field. The females of the early and midsummer broods differ from 

 those of late summer and autumn in the very pale yellow, almost 

 white, colour of the underside of all the wings. In August, this pale 

 yellow deepens, and in early September, reddish streaks appear along 

 the veins of the hind wings beneath, while in October, the entire 

 under surface of the secondaries and the tips of the primaries are 

 heavily streaked or solidly red. The broad outer border of black in 

 some females contains a fev-', more or less distinct, yellow spots, as we 

 see in the female etirytheme or philodice, but a majority of the in- 

 dividuals entirely want these spots, although the border is much less 

 intense than in the males. The colour of the underside of the wings 

 of the male is much deeper in autumn than in early summer, being 

 a light orange, and on the upper side of the primaries the fresh males 

 of October have the black outside border well covered with a beautiful 

 dusting of red scales. In males examples of the August brood only a 

 few scattered (red) scales are to be observed, while a careful examina- 

 tion of many specimens taken in early summer failed to show to the 

 writer a trace of this autumn feature. However, hand-bred specimens 

 might show it, but as I have reared only late summer larvae, I 

 cannot settle the question. Near the base of the front margin of the 

 hind wing in the male is a large, oblong, orange-coloured spot of 

 a mealy appearance. I have noticed the same on the male of 

 Colias eurydice. One female, taken in August several years ago, 

 has the ground colour of the upper side of the front wings white, an 

 approach to the albino, while on the upper side of the hind wings 

 of many of the October specimens the dark streaks and shades from 

 the black border reach almost to the base of the wings. — R. R.

Variety of the Larva of Cuspidia leporina. — Among the 

 larvae of Acrouycta {Cuspidia) leporina, which I took off birch on 

 Wimbledon Common in September last, there was one which had no 

 erect fascicles of short black hairs on the back. — J. F. Bird, Rosedale,

Variation of Nonagria cann^,. — The range of variation of Mr. 

 Bird's and my own series of N. canjice is similar to that of Mr. Bowles 

 {ante, p. 226). It includes the normal red buff males, the normal light 

 buff females, two fine smoky-brown males nearly as dark as black N. 

 typhcB, but more " mousy " in colour, and one smoky female. — A. 

 Robinson, i, Mitre Court Buildings, 'Jemple, E.C. October 7///, 1891. 



Variety of the Larva of Biston hirtaria. — I see a note in 

 the Entomologist'' s Record, vol. ii., p. 156, regarding a pale variety of 

 Biston hirtaria. On looking at my notes of this year, I find that, 

 when those I had in captivity were full-fed, they were pale, while those 

 I then found on the trunks of the apple trees, about to pupate, were 

 dark. I may mention that those in captivity were, during the early 

 part of their lives, kept in glass bottles with wide mouths covered 

 with muslin, so that they did not suffer from want of light. As it was 

 a wet season, those at liberty would have been more exposed to wet, 

 and this may have had something to do with the difference in colour. I 

 kept some of the dark forms, but did not separate the pupae. — C. A.
