XANTHIA G1LVAG0. 77 



The ground colour above is greyish-brown, having 

 a pinkish tinge, darkest on the thoracic segments ; 

 the lines similar, but of a paler tint ; head reddish- 

 brown ; a blackish-brown plate rounded behind on the 

 second segment, through which run the pale dorsal 

 and subdorsal lines ; these lines are, however, on the 

 third and fourth segments, generally much suffused 

 with ground colour, and not always, though sometimes, 

 very distinct on the rest of the body. 



The dorsal line is in some entire, and in others 

 interrupted in the middle of each segment by suffusion 

 of the dark purplish-brown marks it travels through, 

 but it is generally distinct at the beginning of each 

 segment, being there broadly edged with blackish. 

 The purplish-brown mark of each segment on the 

 back is in the centre somewhat of a diamond form, 

 truncated behind, especially on the eleventh and twelfth 

 segments, with the addition of a wedge shape on each 

 anterior side united with it, their points close to the 

 beginning of each segment, and their broad ends 

 forming part of the diamond shape. The subdorsal 

 line paler than the ground colour, often suffused at the 

 end, but visible at the beginning of each segment, 

 being there edged above by a short blackish-brown 

 streak, which forms the point of the wedge portion of 

 the dark mark of the back. The sides slightly mottled 

 with purplish-brown, chiefly about the black spiracles, 

 and close beneath them is a pale stripe of yellowish- 

 grey, its upper edge still paler ; the belly and legs of a 

 similar tint, but a trifle darker. The four tubercular 

 pale dots, ringed with dark brown, are situated within 

 the dark marks on the back of each segment. This is 

 a distinction by which it may be readily identified.
