HADENA DENTINA. 51 



paler than the rest, and rather greenish -yellowish. The 

 dorsal line passes through a pear-shaped rather deeper 

 brown mark on each segment. On the 29th the larva 

 lay up to moult. Food latterly lucerne and knot- 

 grass. 



On the 30th of July it moulted a third time, and was 

 now given knotgrass, Grepis, and Hieracium. Its 

 colour now is a purplish-brown with whitish dorsal and 

 subdorsal lines, the latter margined above at the be- 

 ginning of each segment with a black oblong dash, the 

 blackish-brown tubercular dots distinct, each with a 

 plainly visible bristle. I was still unable to identify 

 this larva and once more speculating as to the proba- 

 bility of its being some Agrotis I had not known. 



The larva moulted again in the night of the 7th of 

 August, and was now easy to identify by my figures 

 of older larvae, being in its fourth coat very different in 

 appearance. It was half an inch in length, stout in 

 proportion, tapering but little in front, and rather 

 more behind. In colour it was now very dingy ; the 

 ground-colour of brownish-grey was on the back and 

 sides very much obscured by dull blackish-grey dorsal 

 broad diamond-shapes of close freckles, relieved by 

 warty ground-coloured tubercular spots, each with a 

 dark centre and bristle ; the dorsal line of brownish- 

 grey ground-colour appears as a very interrupted line 

 of faint freckles, enclosed just at the beginning only 

 of a segment within two squarish black spots ; the 

 subdorsal line is a thin line of grey freckles, margined 

 above just at the beginning of a segment with a short 

 thick oblong dash of velvety- black ; the side is closely 

 freckled with dark blackish-grey like the back, re- 

 lieved by a much-broken line of brownish ground- 

 coloured freckles along the middle and by two tuber- 

 cular warty spots ; spiracles black ; the subspiracular 

 stripe is grey somewhat freckled with darker ; the 

 belly rather paler than the back, and tinged with 

 pinkish, but freckled like the back and sides ; the 

 head rather pinkish-grey, streaked broadly down each
