on the surface, somewhat glossy, the anterior wings 

 with an ochreous yellow patch at the base, and the 

 disk more or less suffused with the same colour ; a 

 dark rust-coloured line extends obliquely across 

 each of them from the tip to the middle of the 

 inner edge, a faint transverse line is likewise ob- 

 servable near the base, and another, sometimes faint 

 and interrupted, towards the hinder margin, to 

 which it is nearly parallel. On the disk, towards 

 the anterior margin, are two white spots, the lower 

 one largest and stained with yellow in the centre. 

 The hinder wings are unspotted, but there is an 

 indistinct transverse streak on each darker than the 

 rest of the surface. The body and antennae are

 white. She lays a considerable number of eggs, 

 which are whitish, surrounded with two green 

 circles, and marked with a dark spot. The cater- 

 pillar has rather a singular appearance from being 

 furnished with two long conical tufts, one of them 

 placed on the back of the second segment and di- 

 rected forwards, the other on the eleventh segment 

 and turned in the opposite direction. On each side 

 of the back there is a linear series of velvet-black 

 spots, followed by a line of yellow spots, and beneath 

 these a number of tufts of white hair. Like so 

 many others of its tribe, it rolls itself in a ring when 

 apprehensive of danger. It feeds on a variety of 

 common grasses, such as Alopecuni-s pratensis, Bro-
