processes in line, and another on each side just below the patch ; also 

 two others in vertical row to the front and opposite the spiracle , on seg- 

 ments 5 to 12 inclusive six processes, three on either side, arranged in 

 triangle as usual in the family ; on the front of 13 are six in cross line, 

 and the triangle on either side to the rear ; along base of body one 

 similar short process over each foot, two on 5 and 6 each, and one each 

 to the remaining segments up to 12, in addition to which is a still shorter 

 process over base of each proleg, and on 5, 6, n and 12 below the other; 

 colour green, with a brown tint ; head scarcely broader than 2, obovoid, 

 slightly bilobed, shining black-brown, with scattered short processes over 

 the face like those of body. Duration of this stage three days. 



After first moult : Length at one day, . 1 inch ; colour variable, some 

 examples being light brown with a green tint, some of brown of darker 

 shades ; the spines as in Phyciodes, rather short, slender and tapering, 

 glossy black, with short bristles about them at a small angle, and rising 

 from shining black tubercles ; head cordate, glossy black, with many 

 curved processes on the front. Duration of this stage, three days. 



After second moult : Length at one day, .14 inch; colour variable, 

 some larvse being wholly black, some rust yellow, some of this last have 

 on dorsum and lower half of side, a dark brown sub-dorsal band inter- 

 vening ; the spines rather longer in proportion than before, otherwise 

 similar ; head as before. Duration of this stage, three to four days. 



After third moult : Length at one day, .3 inch ; shape and spines as 

 before ; the colour as before, but the russet more red, and on those which 

 are wholly russet are two black cross lines to each segment, one on the 

 rear, the other at the junctions ; head as before. To next moult, about 

 four days. 



After fourth moult : Length at one day, .52 inch ; variable as before, 

 the rust colour deepened into red-fulvous. At about six days was full-

 the front of 2 ; on the middle of 2 a dorsal chitinous collar, on which are 

 six small spines, three on either side the mid-dorsal line ; a little below 

 these another ; a long spine below the spiracle ; the spines on the suc- 

 ceeding segments arranged as in Melitfea, black, shining, not long in pro
