for the winter, but only one survived to commence feeding again. 

 On April 14th, it came up from among the close blades of the Luzula 

 pilosa, where it had been hidden, and began to eat and grow ; about 

 the middle of May it moulted, and was full-fed about the end of the 

 first week in June. When I saw that it had begun to shorten, I put 

 it in a large chip box with some moss, and there it spun, and on June 

 13th turned to a pupa. The moth appeared on July 1st. 



All I can now say aboiit the egg is, that it was globular. 



The larva is one of those plain dull-coloured things that do not change much, 

 except in size, throughout their growth. When full-fed, it is rather over three- 

 quarters of an inch in length, somewhat fusiform, being stoutest at the eighth 

 segment, and thence tapering towards the head, and more rapidly towards the 

 tail ; perhaps its most noticeable feature is the extreme shortness of the second seg- 

 ment, which looks quite shrunk, and is about as wide as the head, but the head> 

 being globular, has its rounded lobes a little projecting. 



The ground colour is a pale grey-brown, freckled all over with tiny freckles of 

 ochreous-yellow ; the dorsal line is of a darker tint than the ground, and is edged with 

 paler lines ; the sub-dorsal line is paler than the ground ; the spiracular region is 

 also paler, and slightly inclining to ochreous ; the spiracles are small, and black in 

 colour ; the usual dots distinct, being rather darker than the dorsal line ; the belly 

 paler than the back. 



The cocoon was spun against the side of the chip box, and was of a longish oval 

 shape, being more than five-eighths of an inch long, and less than three-eighths of 

 an inch wide, extremely sUght, being a very open network of silk, with bits of moss 

 drawn in, but still with interstices left, through which the pupa could be seen. 

 The smooth pupa is not quite half an inch long, slender, rather widening at the 

 shoulders, but otherwise cylindrical, and tolerably uniform throughout, the last 

 segment of the abdomen tapering to a blunt spike, which is grooved or fluted in 

 two steps as it were, and its tip set with several small spines with curved ends ; its 

 colom- dark rich brown, the edges of the wing-cases, and the segmental divisions in 

 the abdomen, of a lighter reddish-brown. — J. H.
