looking $ , in rather poor condition, " Arg. charlotta, var. Blackpool, Aug., 1843, 

 J. Gr. E." It is not, however, of that distinct variety, of which there are two 

 specimens in the collection, a fine ^ under-side, " Mus. Dr. Abbot " (J. C. D.), and 

 at side, " Bedford," and another not so well marked, " Peterborough." Perhaps 

 the most singular variety in the entire collection, indeed, of any butterQy that 

 I have ever seen, is a $ of full size and well-developed, but with the body much 

 bloated, and pi-esenting generally a diseased appearance. On the upper-side the 

 whole of the black markings and suffusion are replaced by a very peculiar lint, 

 difficult to describe exactly, but perhaps best expressed by the term, " pale leaden- 

 fuscous " ; the fulvous ground-colour being slightly paler than in the ordinary form, 

 and the distribution of tiie two colours is normal. On the under-side, the fore-wings 

 are nearly as above, and the hind-wings are pale uniform leaden-brown, with no 

 trace whatever of green ; the usual silver spots being present and normal, but 

 rather dull. There is not a trace of black pigment in any part of the insect, which 

 is in good condition, hut a little damaged at the anal angle of both hind-wings. It is 

 labelled "Dover, Leplaistrier " (J. C. D.), and is thus referred to by the Rev. 

 W. T. Bree in Loudon's Mag. Nat. History, vol. V (1832), p. 33i, footnote J :— 

 "A singular variety (of ^J. ff^^aja), pale buff-coloured, and with the black spots 

 and markings very faint. It was taken, as I am informed, in a remarkably wet 

 Season. The specimen reminds me almost of some plant which, having gi-own in 

 the dark, has in consequence produced its flowers nearly colourless." 



Argynnis lathonia, L. — A series of 14 specimens ; a $ , " Mus. Dr. Abbot, 

 White Wood, Gamlingay, Canib., June, 1803, Dr. Abbot " (J. C. D.), is fairly good ; 

 a rather poor specimen, " Halvergate, Norf., A. H. Haworth G. S," is dated at side, 

 " 1818," and two good under-sides, " Birch Wood, B. Standish," bear the same date. 

 A ^ is " From Mr. Curtis," and two very good under-sides " Dover, Leplaistrier " ; 

 a better J ," Gray, Junior, Dover, 1880 ; others are "Dover, 1826," " Kirkman's 

 sale, 1817," and "From J. G. Boss" (C. W. D.). 



Argynnis euphrosyne, L. — A varied series, among them an old specimen with 

 the basal black spots enlarged and confluent, and the marginal silver spots on the 

 hind-wings beneath absent, " n. Bedford," probably one of Dr. Abbot's specimens. 

 One with hind-wings and apex of fore-wings deeply suffused with olive-brown, 

 " G. King, July 20/59." Two exceedingly fine dark varieties, " Taken near 

 Colchester." The first is almost entirely dark rich brown on both sides, the black 

 spots scarcely visible except on the hind-wings, in which each spot of the sub- 

 marginal row stands in a dark fulvous ring. The silver spots on the under-side 

 are normal, and stand out very brilliantly against the dark ground-colour. The 

 second is even more singular, being above somewhat similar to the preceding, but 

 more suffused with fulvous ; on the under-side, the black basal spots on the right 

 fore-wing are much enlarged and confluent. The basal half of the hind-wings is 

 pale yellow, the marginal half red-brown ; there is a large silvery longitudinal 

 costal dash, and the central and marginal silvery spots are much enlarged, and the 

 latter elongated towards the base of the wings.
