34 HAUSTELLATA. — LEPIDOPTERA. 



yellowish iris, corresponding with the series on the upper surface ; ciUa yel- 

 lowish, interrupted with black : body black above, yellowish beneath : an- 

 tenntc brownish above, interrupted with whitish, which last colour predo- 

 minates beneath. 

 Caterpillar black, spotted with white : the head and prolegs fulvous : the legs 

 and spines black. Chrysalis stout, black, sprinkled on the ventral segments 

 with grayish dots, and on the back with fulvous tubercles : the perfect insect 

 appears in about a month. The cateqiillar feeds on various kinds of plan- 

 tain, on ribwort, speedwell, mouse-eared hawkweed, Szc. ; it is produced in 

 the autumn, and lives throughout the winter in society, beneath a silken web, 

 and in April it becomes full grown and changes to a pupa ; it is much sub- 

 ject to the attacks of ichneumonida and muscidae. 



This is a very local species, and is found in meadows by the sides 

 of woods : in Wilkes's time it was not uncommon in Tottenham- 

 wood : recently the places where it has been chiefly observed have 

 been near Hyde and the Sandrock hotel, Isle of Wight; in the 

 latter place in plenty : also at Birch-wood, and near Dartford and 

 Dover, and in a wood near Bedford. I believe it has been found 

 in Yorkshire; and from Ray, p. 121, it would appear to have been 

 abundant in Lincolnshire in his time. It generally flies in June.

^Fings above fulvous, spotted with black ; the base of the posterior nearly 

 black ; beneath, the latter are purplish, with six or seven small silvery spots 

 at the base, intermixed with minute yellowish dots; a band composed of 

 silvery and yellowish spots, then a puplish-white streak, in which is a series 

 of circular spots, slightly piipillated ; and finally, in the margin is a series 

 of silvery lunules: the cilia are whitish, interrupted by brown. 



Caterpillar black, the back griseous with a longitudinal Une, the spines altei-- 

 nately white and reddish : it feeds on the viola odorata : chrysalis yellowish, 

 varied with black. 



Stewart appears to have introduced this species; but he does not give any 

 authority for so doing. I have a reputed English specimen, but as I cannot 

 vouch for its authenticity, it is better to remain silent. Like the other two 

 species of this section. Me, Dia is double-brooded on the continent.
