130 [November, 



The moths from the New Forest were bred on July 7th to 17th, 

 and those from Hartlepool on July 13th to 17th ; and here it may be 

 stated there was no very appreciable difference 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, appearing almost 

 truncated at the ends, the shell numerously ribbed and finely reticu- 

 lated ; 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, the head and neck 

 plate darkish brown, and a paler brown anal plate : by the middle of 

 November the case or gallery it has constructed is a quarter of an 

 inch long, composed outwardly 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, the skin slightly glistening and of a lightish mahogany- 

 brown colour, the usual spots glossy dark transparent brown with a 

 black dot in each — the plates and head also dark transparent brown 

 — the lobes of the head very dark, also the mouth, ocelli 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 near full growth they inhabit tubular galleries two inches long 

 of irregular figure, and firmly attached to the grass in an upright 

 position with the lower end touching the ground, and fabricated of 

 grey silk covered with particles of moss, frass, and grains of earth. 



When full-grown the larva is three-quarters of an inch long, of 

 moderate stoutness, cylindrical, though tapering a little at the three 

 hinder segments, and the head is rather smaller than the second, the 

 segments are well defined and have a sub-dividing wrinkle about in the 

 middle of each : the ground-colour of the body is a dirty greyish- 

 green rather inclining to glaucous and a little paler on the belly, the
