BRITISH BUTTERFLIES. 



is rather wider than the second segment, dis- 

 tinctly exserted, prone and rough with minute 

 warts ; the body is cylindrical, and very 

 gradually attenuated towards the anal ex- 

 tremity, which terminates in two parallel 

 points above the anal flap, and directed back- 

 wards ; the surface of the body is almost 

 smooth ; warts, indeed, are observable, but so 

 minute as not to communicate a scabrous 

 appearance, nor are there any noticeable hairs 

 or bristles. The colour of the head and body 

 is apple-green, inclining to olive-green ; the 

 head is dull, opaque, and uniformly coloured ; 

 the body is striped ; there is a narrow medio- 

 dorsal stripe dark purple green, bordered on 

 each side by a still narrower yellow stripe ; 

 these three stripes terminate before the anal 

 points ; on each side are two pale yellow 

 stripes, one above, the other below, the pale 

 brown spiracles ; the upper of these is bor- 

 dered above and below with dark blueish 

 green, and terminates in the anal flap, which 

 is tinged with pink ; the lower terminates 

 before the anal flap ; the ventral surface, legs, 

 and claspers are bottle-green. Two days sub- 

 sequently namely, on the 28th of May 

 they underwent pupation. The CHRYSALIS has 

 the head truncate and slightly produced at 

 the angles and also in the middle ; the wing- 

 cases are very slightly produced at the 

 shoulders ; the thorax is dorsally convex, with 

 a very slight median keel ; the chrysalis is 

 suspended by minute caudal hooks from a 

 white silken web spun on the edge of a leaf of 

 its food-plant ; the colour of the wing-cases is 

 pale brown, with a darker arcuate median 

 linear mark extending from the base to the 

 margin, and a much shorter mark of the same 

 colour in front of this, originating in the disk, 

 but also extending to the margin ; the head, 

 thorax, and abdomen are apple-green, sprinkled 

 with dingy whitish green. The butterflies 

 produced from the individuals described ap- 

 peared on the wing on the 4th and 5th of 

 June. I am indebted to Mr. Hudson, of 

 Bawtry, for specimens of the egg, caterpillar, 

 and chrysalis ; for a supply of the food-plant ; 

 and for information respecting the economy of 

 this species. Newman. 



Obs. At page 35 of the first volume of the 

 " Entomologists' Weekly Intelligencer," Mr. 

 Joseph Chappell states that the caterpillar 

 also feeds on the cotton grass, near the roots, 

 in May. 



TIME OP APPEARANCE. End of June, July, 

 and sometimes in August and September. 



LOCALITIES. It has never be. n found in 

 Ireland, the Isle of Man, or Scotland. T lie 

 English localities are as follow : 



Cheshire. In Delamere forest Noah 

 Greening. 



Cumberland. On all the mosses in Cum- 

 berland,.and I obtained a specimen last season, 

 taken along with Epiphron, that almost looked 

 like a new species, the black spots being as 

 clear and bright as in Tithonw, and the spots 

 were differently placed. Icall it thePolydama 

 variety J. B. Hodgkinson. 



Durham. This insect frequents our wet 

 mossy bogs in July, and I have taken it also 

 late in June and early in August. Needless 

 Hall Moor, moors about Cambo, Prestwich 

 Carr, Muckle Moor, near Hayden Bridge ; 

 moss near Craigclough, moors near Shull 

 William Backhouse in " Wailes' Catalogue." 



Lancashire. Sim inon's Wood Moss Edwin 

 Birchall ; Chat Moss, near Manchester, 6th 

 September, 1868 Joseph Leigh in "Entomo- 

 logist," iv. 147. 



Northumberland. Plentiful in Prestwich 

 Carr before it was drained ; I have not heard 

 of any captures lately William Maling. 



Staffordshire. Chartley Park, near Uttoxe- 

 ter Stainton's " Manual." 



Westmoreland. Abundant in the mosses at 

 Witherslack in June and July J. B. Hody- 

 kinson. 



Yorkshire. Thorne Moor, near Doncaster 

 Alfred Ecroyd ; Hadfield Fens E. Bir- 

 chall. I took it at Thorne Moor, but wasted, 

 and had specimens given me from Cottingham, 

 near Hull. In visiting this latter locality, 1 

 find it differs from Thorne Moor, which is 

 mossy or spongy ; but the Cottingham locality 

 is rather like those spots where I have taki-n
