1880.. I 171 



gregarious; for although in this instance they were able to conform 

 to circumstances, I dip not fail to witness a little testy and resentful 

 behaviour by one larva when intruded on by another. They were lovers 

 of sunshine, and whenever they felt the genial rays, came forth to spin 

 with increased energy. 



Five moths in all were bred, on Sept. 13th, 16th, 30th, and Oct. Ist. 



The egg of carnella when first laid is round, flat and scale-like 

 whitish, then tui-ning yellow, afterwards streaked with reddish, again 

 changing to fawn colour and becoming convex above, and, an hour or 

 two before hatching, showing a dark purplish spot on the upper surface. 



The larva on quitting the shell is of a pale drab tint with darker 

 dorsal line, blackish head and collar ; its pace is running rather than 

 walking : in four days' time it shows traces of other lines besides the 

 dorsal one, and on the nineteenth day is nearly an eighth of an inch 

 long, of pale pinkish-green tinted body, with numerous dark brown 

 lines along its length, the head and collar dull black. 



After hibernation it is nearly three-sixteenths of an inch long, 

 slender, and marked as before with alternate lines, now of green and 

 blackish, a design which continues to be developed, the head and 

 second segment black, and for a time even the pair of legs of that seg- 

 ment are black, all without any gloss, save a slight glistening on the 

 anal flap, the beginning of the green lines on the thoracic segments is 

 quite pale, and the sub-dorsal one is rather conspicuously so, the dorsal 

 is a straight black line, and from it to the spiracles on either side are 

 four black and five green ragged-edged lines, making a total of nineteen 

 lines from one spiracular region to the other ; as the larval growth 

 increases to half an inch and more, the green becomes bluer, then more 

 slaty, and the black lines less and less intense ; the dingy green belly 

 has two black lines above the legs, a black ring round each ventral leg, 

 and a ventral black line. 



The last moult produces a skin which seems for a time to be 

 black, but by degrees, as the larva attains its full growth of seven- 

 eighths or nearly an inch in length, traces of the lines re-appear with- 

 out much effect of breaking the general bronzy-blackness of the skin ; 

 this is rather rough with fine transverse wrinkles, and one much 

 deeper sub-dividing each segment; the body in front tapers a little from 

 the third segment to the head and more behind from the tenth to thir- 

 teenth. The second segment and the head having remained deep dull 

 black, begin at the very last to glisten faintly ; the papillse are pinkish- 

 grey tipped with black, parts of the mouth being of the same grey colour 

 with a black streak midway across the upper lip : some parts of the
