14S [June, 



Otiier localities for C. dispar besides those aforesaid mentioned, were Stilton 

 Fen, Migg Mere, Trundle Mere, and Sawtree Fen, in Huntingdonshire ; Boggles- 

 well, in Cambridgeshire ; Bardolph Fen in Norfolk ; and Benacre in Suffolk. Mr. 

 Haworth, in a letter to my father, dated from liis brother-in-law's, Mr. Scales, of 

 Eeecham, near Wells, in Norfolk, writes, " I went round from Wisbeach to this 

 place, passing the old habitats of Papilio dispar, now waving with corn." Mr. 

 Haworth had an estate at Halvergate, in which lie took Ai-gynnis Lathonia. 



In the "Entomologist" for 1840-2, p. 156, Mr. Doubleday records the larva of 

 C. dispar as being very plentiful in Holme Fen between June 3rd and 20th, 18tl. 

 Mr. Dawson, in the " Zoologist" for 1848, p. 2113, writes, " L. dispar has become 

 very nearly extinct, I could only hear of five larvae being taken, and very few of the 

 perfect insect." 



Mr. Stainton, in the " Transactions of the Entomological Society of London " 

 (2), V, |). 234 (1860) writes " C. dispar used to be abundant in Wittlesea Mere, 

 but since tliat was drained, causing corn-fields to wave where i-eeds had formerly 

 held undisputed sway, the insect has disappeared. Similar fen districts still exist 

 in Norfolk and Suffolk, but no recent captures are known, although tlie insect has 

 been sought there in its most likely haunts." 



Good varieties of this species are scarce. The best I know of are fa) A female 

 ill my own collection almost entirely black, blacker even than the var. Eleiis of C. 

 Phlctan. Tiiis my father received froai Mr. Simmonds in 1837, by whom it was 

 bred ; (hj one approaching the var. Sckmidfii of C. Ph/(vas, having tlie hind-wings 

 inclining to silvery towards the hind margins. This specimen was in Mr. Side- 

 botham's collection and is now in the National Collection at South Koisington ; fcj 

 a female, with the discoidal spots elongated, is in the Doubleday Collection at 

 Bethnal Green. 



The hind-wings of some specimens are almost black, one being hardly irrorated 

 with copper at all, the broad upper band standing forth very distinctly. In others 

 the copper colour greatly preponderates. One that Mr. Standish took had un- 

 usually large spots on the under-side. 



My father, in " Loudon's Magazine," vol. vii, gives an instance of variation iu 

 shape of the upper wings of two males, tho.se of one being long and acute, those of 

 the other short and obtuse. 



There is also considerable difference in size — the smallest specimen in my 

 collection measures one inch and five lines across the wings, and the largest two 

 inches and two lines. 



In tht^ Oxford University Museum are two specimens of a species of 

 Ichneiimonidfe bred from C. dispar, whicli are apparently Limneria tnutahilis.
