28 LITHOSIA MUSCNRDA. 



The larva retired into a curled-up bramble leaf, and 

 there formed a thin, webby cocoon of greyish silk, 

 outside which was a finer and thinner web of white 

 silk. (W. B. and J. H., 9, 12, 71 ; E.M.M. VIII, 

 173.) 



A larva received from the Rev. J. Hellins in 1871 

 (date not given) was three-quarters of an inch long, 

 cylindrical, of tolerably uniform bulk, only the second 

 and thirteenth segments tapering; the head smaller 

 than the second segment ; the legs and prolegs well 

 developed. 



The warty tubercles in high relief in pairs, on each 

 segment down the back; the first pair moderately 

 small, the second pair very large and swollen, trans- 

 versely oval ; two rows of tubercles along the sides, 

 i. e. one in each row on each segment ; across the 

 third and fourth segments the tubercles on the back 

 in pairs, the largest in front, and the smallest partly 

 behind it in an oblique direction. 



The head is of a brilliant shining black ; the body 

 a velvety blackish-brown, the dorsal and subdorsal 

 stripes deep black; the ground colour between them 

 is marbled with reddish-grey, and there is a fine, in- 

 terrupted, reddish-grey, subspiracular line ; the tuber- 

 cles are deep brown, thickly beset with radiating 

 hairs of the same colour; the front pairs of small 

 tubercles are set in rings of reddish-grey. On the 

 second segment on each side of the dorsal stripe and 

 on the anterior portion of the thirteenth segment on 

 each side of the dorsal line, there is a squarish deep 

 dull red spot. The belly pinkish-grey. The legs and 

 prolegs dark reddish-grey and shining, the tips of the 

 latter pellucid. 



This larva died after spinning its web, but another 

 in 1874 produced the moth June 24th. (W. B., Note 

 Book I, 78.)
