CAPTURES AND FIELD REPORTS. 285 



Chrysophanus phlceas and var. Schmidtii at Erith. — This species 

 has been decidedly scarce this season ; but I obtained a few ova from 

 females of the first brood, and reared some sixty imagines — all very 

 normal. From some of these and some captured females I got a much 

 larger supply of ova, and during the month of August had many 

 hundreds of larvfB feeding ; but the chilly September weather checked 

 the gi'owth of many of them, so that only two hundred reached the 

 perfect state. Among these imagines is a small series of golden forms, 

 nine in all, which are a striking contrast to the type. I should mention 

 that my son took a very fair male schmidtii in one of his expeditions 

 after females of the second brood for ova, and obtained several of this 

 latter sex at the same spot, and most probably the one that had paired 

 with said schmidtii — hence, I think, these golden forms. Amongst 

 other abnormal forms I bred a large female of the ordinary type, but 

 minus the left fore wing, and with the left hind wing suffused very 

 much after the style of C. dispar. The remainder of the larvae — some 

 hundreds — are many of them half-fed and more, but, I fear, will not 

 get through the coming winter. I judge so from past experience, 

 although I have once got a very small percentage through all right. —

Aberrations of Dragonflies. — With reference to the article by 

 Messrs. F. W. and H. Campion [ante, p. 252), I may say that during 

 the second half of July this year I saw a number of olive-coloured 

 females of Ischnura eJegnns at Wicken. A corresponding variety of a 

 more abundant species, I think [Enullagma cyathigenim), Avas also very 

 common ; in fact, in thirty-five couples which I saw attached per colUim, 

 twenty of the females were of the greenish variety. I also saw several 

 green females of I. elegans in copulation. I tried to get both species to 

 lay eggs, in the hope of breeding from them, but was unsuccessful. 

 Siiould anyone be successful in breeding from one of these varieties, 

 valuable results might be obtained on the question of heredity in its 

 relation to sex. — Leonard Doncaster ; Zoological Laboratory, Cam- 

 bridge, Oct. 7th, 1904.

CoLiAs edusa at Erith. — This species has put in an appearance in 

 and around this neighbourhood this autumn, but not in any numbers. 

 The only female netted kindly deposited a few ova, which duly hatched 

 out, and the larvae fed up on growing white clover, and I have half a 

 dozen pupae dating from 8th inst. I suppose they will emerge this 

 season. The rest of the larvae seem to have disappeared save one half- 

 grown specimen. — E. Sabine ; Erith, Oct. 20th, 1904. 



CoLiAS EDUSA IN CORNWALL. — On Aug. 24th I noticed a freshly- 

 emerged male of Eitrymus croceus [CoUas edusa) at Donnderry, a small 

 seaside resort midway between Piame Head and Looe. — Thos. Bain- 

 BRiGGE Fletcher; Sept. 25th, 1904. 



Colias edusa in Hampshire. — I have seen a few specimens of 

 C. edusa, and have heard of others having been observed in this neigh -
