ER YCINIDAZ. 103 



olive, uiuch darker at the centre of each segment ; subdorsal 

 lines oblique, dai-k olive, with a dull yellow spot on the hinder 

 part of each segment. A largish orange-coloured tubercular 

 spot, surmounted by a tuft of reddish-orange hairs, is on each 

 segment on each side of the dorsal line, and a similar smaller 

 spot below the subdorsal line. Spiracular line indistinct, 

 olive in front, dull yellow behind. Spiracles black. Head 

 reddish-yellow. (H. H. Crewe.) 



On cowslip {Frimnbi irris), feeding on the under side of 

 the leaves, eating holes in them ; also on primrose {Primula 

 vulgans). 



Middle of June to August. 



Pupa pale straw colour, with a double row of dorsal black 

 spots and three rows of the same on each side, the middle 

 row the smallest ; upper border of wing cases black, and two 

 black bauds across the front of the thorax. (Crewe.) 



In the pupa state thi-ough the whiter. 



A very pretty little butterfly, widely distributed, occurring 

 only in woods, and loving sheltered sunny spots at the bottom 

 of hollows and valleys, and broad, sheltered wood paths. 

 Here it flits about over the lower under\YOod, constantly re- 

 turning to the same spot, and settling on the same favourite 

 bush, or even on the same twig. So strong is the liking of 

 the insect for some particular resting-place, such as a little 

 oak sapling, three feet high, in a flowery comer, that when 

 one specimen is captured another will take its place in a few 

 hours, and this may be continued day after day. Although 

 resting at so short a distance from the .ground, it is veiy little 

 attracted by flowers, the only kind which appears to be at all 

 favoured being the blossom of Evphorhia aiaijgdnloidcs (wood 

 spurge), and this only occasionally. On the Continent it is 

 said to be double-brooded, the second emergence taking place 

 in August. In this connection it is curious to find that pupae 

 here, kept indoors in a cold place, produce the butterflies right 

 through the winter.
