8 DIANTHiEOIA 02BSIA'. 



the larva of 1867 suits every subsequent stage up to 

 full growth. 



The full-grown larva was cylindrical, of moderate 

 stoutness and about equal bulk throughout; the head 

 rounded, and the anal segment only slightly tapered, 

 and rounded off ; the segments and sub-divisions very 

 well defined. The ground-colour on the back was 

 pale greyish-ochreous, that of the sides, belly, and legs 

 similar, but a little more ochreous-brown, and deeper; 

 on each segment, and co-extensive with it in length 

 and in breadth, extending to the subdorsal region, was 

 a diamond-shaped mark, composed of dark grey-brown 

 freckles thickly aggregated together ; a broad band of 

 similar freckling commenced along the subdorsal 

 region and terminated rather below the spiracles ; 

 other freckles, fainter and farther apart, were low on 

 the sides, disappearing gradually towards the legs, 

 which were tipped with broad hooks ; the head shining 

 reddish- brown, the plate on the second segment was 

 rather shining reddish grey-brown, and had a broad 

 dark brown margin in front ; the tubercular dots were 

 whitish centres in rings of dark grey-brown, arranged 

 in threes on either side the back of each segment; 

 others, whose place was within the side band of 

 freckles, were of the ground colour ; the spiracles pale 

 brown, outlined with black; just at the last, when the 

 larva was in its plumpest condition, the last three 

 segments appeared to taper a little. 



There was a faint indication at first of a dorsal line 

 or thread of pale ground-colour enclosed within two 

 dark grey-brown ones, but not very visible beyond the 

 thoracic segments, excepting just at the segmental 

 divisions. (W. B., July, 1872 ; E.M.M., August, 1872, 

 IX, 64.)
