colour ; on the sides of the third and fourth segments is a triangular 

 group of three large brownish-yellow horny spots, the ordinary 

 tubercular dots on other parts of the body are very minute, each with 

 a fine short bristly hair, and a faintly paler ring round its base ; the 

 spiracles black, the narrow plate of yellowish-brown on the fore part 

 of the anal segment has its front margin rather bluntly pointed in the 

 centre, that of the anal flap is of the same shining colour, flattened, 

 but with a little raised ridge round behind, from which proceeds a few 

 short bristly hairs, the ventral and anal legs tipped with brown hooks, 

 the skin of the body is smooth but without gloss. 



The pupa is subterranean but often lies only a short distance 

 beneath the surface, and sometimes is scarcely buried amongst vegeta- 

 ble remains slightly held together by a few threads of silk ; it is five- 

 sixteenths of an inch in length, and of the usual Noctua form, stout 

 across the thorax, the abdomen tapering and ending with two fine 

 points : its colour for a time is very pale brown, afterwards dark 

 brown, its surface shining.
