be stated that there was no very appreciable differ- 

 ence in the moths from either locality, beyond this, 

 that the darkest southern example was of a satiny 

 creamy-yellowish ground colour, with the veins and 

 inner margin dark bronzy-green ; the darkest from 

 the North was of a whitish cream-colour and bronzy- 

 brown ; while on the other hand the lighter examples 

 of the South had the veins and inner margin browner, 

 while the northern were more green. 



The shape of the egg is broadly elliptical, appear- 

 ing almost truncated at the ends, with the shell 

 numerously ribbed and finely reticulated ; the colour 

 when first laid is pale straw, changing gradually in a 

 day or two to pinkish-red, which deepens until about 

 the tenth or eleventh day, when it is brownish-red 

 with a greyish-brown spot at one end, and then 

 hatches in a few hours. 



The young larva is of a light salmon-red colour, 

 showing an internal deeper reddish vessel through 

 the skin, with the head and neck-plate darkish 

 brown, and a paler brown anal plate ; by the middle 

 of November the case or gallery which it has con- 

 structed is a quarter of an inch long, composed out- 

 wardly of finely comminuted grassy particles firmly 

 attached to the grass about three-quarters of an inch 

 above ground ; the larva itself at that time, while yet 

 feeding during mild days, is nearly three-sixteenths of 

 an inch long, and comes out readily from its abode 

 when disturbed ; it is of stoutish character, tapering 

 a little posteriorly, with the skin slightly glistening 

 and of a lightish mahogany-brown colour ; the usual 

 spots are glossy dark transparent brown with a black 

 dot in each ; the plates and head are also dark trans- 

 parent brown, the lobes of the head very dark, also 

 the mouth ; the ocelli are black. 



After hibernation some are full-fed and spun up by 

 the end of May, while others are not yet full-grown, 

 ranging in length from half an inch to five-eighths, 

 and go on feeding till the second week in June ; when
