86 NEMEOBIUS LUCINA. 



one or two eggs were to be seen laid on the underside 

 of the cowslip leaves. 



The plant was put aside and forgotten for three 

 weeks or so when I brought it out to inspect, and 

 found that the eggs had hatched. A cylinder was 

 then placed over the plant, and the next day three 

 larvas were to be seen making holes in the leaves. 

 At this time they certainly seemed rather of an onisci- 

 form shape, but this form soon began to disappear, 

 and as they approached their full growth the ravages 

 they made on the leaves of the plant were very great. 



By the 18th of July they were about three-quarters 

 of an inch long, rather thick in proportion, the head 

 smaller than the second segment, and the second a 

 little smaller than the third, the outline of the back a 

 little convex in shape, and the last three segments 

 tapering a little. 



The colour of the head was pale orange-brown, that 

 of the back as far as the spiracles of a deep ochreous- 

 brown, the surface being composed of warty swell- 

 ings, which on the back especially, though rather less 

 so on the sides, were covered with a fine down or 

 shaggy pubescence, and in addition each wart emitted 

 a fascicle of stout, bristly, rather curved hairs. 



Below the spiracles the colour was of a paler brown, 

 sometimes greyish. The warts above the legs were 

 furnished with pale, whity-brown, curved hairs, form- 

 ing a complete lateral fringe, the prolegs equally pale. 

 The dorsal stripe was only visible as a black spot 

 towards the anterior part of each segment. The 

 spiracles were of the ground colour strongly outlined 

 with black. (W. B., Note-Book I, 40.) 



On the 29th of May, 1879, the Rev. J. Campbell 

 Parson brought me a pair of this species taken in cop. 

 They, were placed on the 31st on some potted plants 

 of cowslip. The male lived nine days and the female 

 fifteen. 



On the twelfth day five eggs were visible laid on 

 the upper surface of a leaf, some near the middle of the
