62 XYLOMYGES CONSPIC1LLARIS. 



widish dorsal and narrower subdorsal lines ; the head 

 of a yellower green, sprinkled with black atoms. 

 After the second moult the same tint of green is re- 

 tained, with the dorsal and subdorsal lines as before, 

 but now a still paler spiracular stripe appears, and in 

 this stage — when the larva is about three-eighths of 

 an inch long — it is much like the young larva of 

 Tdeniocampa gothica, except that it is more slender, and 

 the pale lines are not so white or so sharply defined. 

 After the third moult the colours are much as before, 

 but now the spiracular stripe is decidedly greenish - 

 yellow or ochreous-yellow, and the tubercular black 

 dots are imperfectly ringed with whitish-yellow. After 

 the fourth moult the general colouring, though deep 

 and of sober richness for a time, gradually grows paler, 

 and three varieties could be noticed, brownish-green, 

 ochreous-green, and one or two light brown ; the 

 markings as before. 



When the larva is about an inch long the last moult 

 occurs, and the size and colouring become that now to 

 be described as belonging to the full-grown larva. The 

 length is from an inch and a half to an inch and five- 

 eighths, the figure tolerably stout, cylindrical, yet 

 tapering very little at either extremity, the eleventh 

 and twelfth segments being rather the thickest, and 

 all the divisions very slightly denned ; the skin soft and 

 smooth. The colour of the glistening head is pale 

 pinkish-drab, with a blackish-brown streak down the 

 front of each lobe, a finer streak at the side, and deli- 

 cate reticulations on the other parts. The ground 

 colour of the back and sides isochreous-greenish brown, 

 very much, but finely, freckled with brownish-grey ; 

 the second segment is thickly freckled with dark grey- 

 brown, and edged on the front margin with very dark 

 grey, through which, rather distinctly, pass the fine 

 thread-like dorsal and subdorsal lines, a trifle paler 

 than the ground ; but on the rest of the body they are 

 of the ground colour, merely relieved with outlines of 

 grey-brown, and can only just be traced in their course,
