HESPERID^. 291 



bluish green, with a darker green dorsal stripe, a very pale 

 green spiracular stripe, and sometimes a veiy indistinct sub- 

 dorsal darker green line ; spiracles green or pinkish ; legs and 

 prolegs green. The young larva on emerging from the egg 

 is said by the Rev. J. Hellins to be of a pale yellowish with 

 the skin much puckered ; the dots black, small, and " set 

 with the very shortest bristles I ever noticed in a young 

 larva, giving it a very bare look " ; the head large and smooth, 

 stuck on like a large flattish button, brilliant jet black, as 

 also is a narrow collar on the second segment ; the four 

 bristles on the anal segment somewhat longer than the rest. 

 At the end of three weeks it is about half an inch long and 

 the colour has become dull green ; the head and the thin 

 curved collar still shining black. At this time it spins 

 together the edges of the grass blades and makes a long 

 narrow, tough, silken, opaque web, not much bigger than 

 itself, for a hiding-place, and in this it hybernates, probably 

 recommencing to feed in April. In May it has become pale 

 green ; the skin thickly covered with very short dark brown 

 bristles ; the head dirty white, with a dark brown stripe 

 down the outer edge of each lobe; second segment now 

 whitish green. 



Lang says that the dorsal line is dotted with black, but he 

 may refer to the minute blackish raised dots from which the 

 hairs spring and which are plentifully distributed over the 

 body. Berge called the spiracular stripe yellowish, but this 

 may be a variation. It is singular that neither these writers 

 nor Buckler nor Hellins mention the curious white spots on 

 the underside of the body near the anal extremity ; neither 

 is there any indication of them in Buckler's figures. Possibly 

 considering them (with Staudinger) as a wax-exudation, these 

 writers have not regarded these spots as any part of the 

 markings of the larva. Zeller, however, states distinctly that 

 these spots appear, as snow-white patches, on the underside of 

 the tenth and eleventh segments, in the full-grown larva.
