98 ANTHROCEKA FILIPENDUL^. 



The full-grown larva is 19 mm. long when at rest, 

 23 mm. when walking, 7 mm. across the widest part ; 

 the figure is soft and fat, tapering from segment 9 to 

 the tail, and more gradually forwards to the head ; the 

 head is small, retractile into the second segment ; the 

 segmental divisions well cut; on each segment is a trans- 

 verse row of eight raised tubercles, the two trapezoidal 

 dots on each side of the back being united in an elon- 

 gated tubercle, something like a dumb-bell in shape. 

 All the tubercles are set with short hairs, the skin 

 outside is full of little warts and points. The general 

 colour dull greenish ; all the tubercles are so coloured, 

 and by their interference cut up the black markings ; 

 the dorsal line is yellowish-green, but bearing a yellow 

 spot at the hinder end of each segment ; on either side 

 of this comes what would be a velvet black stripe, but 

 is cut up by the transverse tubercles into a row of 

 black spots, so that on each segment there is a bigger 

 blotch in front and a smaller one behind the tubercle. 

 When the folds are contracted the hinder blotch on 

 each segment coalesces with the front one on the next, 

 so as to make one large irregular blotch ; below this 

 row comes a subdorsal line of the ground colour, bearing 

 nine spots of deep yellow placed on the hinder edge of 

 each of segments 3 to 11 ; on this line commence the 

 upper ends of a row (reckoned lengthwise) of large 

 oval tubercles, the lower ends of which intrude into a 

 series of black spots, hollowing them out into a half- 

 moon shape. On the lower edge of these black marks 

 come the black indistinct spiracles ; below again comes 

 a row of long oval tubercles, with their longer axis 

 running with the length of the larva, and their lower 

 sides edged with black, and then another row of small 

 tubercles, also set in black half -moons ; the ventral pro- 

 legs have triangular tubercles on their sides ; the belly 

 is green, the head and thoracic legs are black ; the short 

 hairs on the tubercles are mostly whitish, but some are 

 black.
