are black ; there is a rich velvety, very black, dorsal 

 stripe ; the subdorsal line, being broken on each 

 segment by the hinder tubercle with its tuft of hair, 

 must be rather called a row of elongated, parti- 

 coloured spots, each beginning on the hinder part of 

 a segment, and continued across the fold into the 

 next segment, until stopped by the tubercle ; the 

 colours being white for about half the spot, and the 

 tint of a robin's red breast for the remainder, but 

 owing to the position of the white portion so near the 

 segmental fold, only the red hinder part of the spot is 

 to be seen except when the larva is stretched out in 

 walking. On segments 2 to 4 these spots are alto- 

 gether whitish. Immediately below comes another 

 velvety black stripe, broadest at the centre of the 

 body, and tapering considerably towards the head, but 

 less so towards the tail ; just above the feet comes a 

 greyish-ochreous interrupted stripe, edged on both 

 sides with a dark brown line ; the tubercles and short 

 hairs are brown, the longer ones black. 



The pupa stout, reddish-brown in colour; enclosed 

 in a very slight web of silk, under cover of a stone or 

 piece of moss. (J. H., 5, 9, 68; E.M.M. V, 109.)

Mr. Doubleday kindly sent me eggs on the 11th 

 August, 1867, from which the larva? hatched on the 

 15th of August. By the end of November the larva? 

 were nearly half an inch in length and were full-grown 

 during May. The moths appeared from June 14th to 

 27th, 1868. 



The larvae fed at first on withered leaves, especially 

 delighting to riddle decaying sallow leaves full of holes ; 

 but I saw them also eat a little clover, knot-grass, and 

 various lichens and mosses* Early in the spring they
