54 VANESSA ANTIOPA. 



the flat roof, where it began to spin a little and 

 remained quiet, but the next morning I saw it had 

 moved and that two pellets of "frass" had been 

 ejected, whereupon it was restored to its food, on 

 which it at once made a hearty meal, and then slept 

 on the birch twig, having previously taken the pre- 

 caution to spin a few threads for a secure foothold. 

 This larva was finally full-fed on the evening of the 

 30th July, and spun itself up to the top of its cage, and 

 the following day hung suspended by the tail ; on the 

 2nd of August it was a pupa. This measured eleven 

 lines in length, and in form closely resembled that of 

 Vanessa poly Mows in all respects, except that the 

 spiky-points were longer and sharper than in V. jpoly- 

 chloros ; its colour was a very dark and dingy blackish- 

 brown. 



In the younger larvae, which varied in length from 

 an inch and an eighth to an inch and a quarter, the 

 pubescence was more dense, almost with a shaggy 

 appearance, and the naked spots on the back were 

 darkish green, as were also the ventral prolegs ; but 

 with the increase of growth the black skin showed more 

 and more between the hairs, which do not grow, and 

 the larva increases in blackness. These larvae lived only 

 a few days, probably being diseased from having eaten 

 the birch leaves in too dry and withered a condition 

 during their journey hither in a wooden box. 



The dorsal row of shorter spines commences on the 

 seventh segment ; there is a subdorsal pair on the front 

 division of the thirteenth segment, as also on the anal 

 flap. (W. B., Note-Book IV, 206.)

On the 15th of June, 1870, two full-fed larvae on 

 elm twigs were received from the Rev. J. Hellins ; 

 their length when stretched was two inches.
