DIANTH^CIA A LB) MACULA. 5 



along from the hinder dot of one segment to the hinder 

 dot of the next; beneath this is the subdorsal 

 interval of clear and paler ground-colour; and then 

 come two broad and irregularly thickened stripes of 

 freckles, which about the middle of each segment 

 slope towards each other till they touch, then returning 

 to their previous level ; the ground in the space just 

 below the point of contact is filled with freckles 

 which partly surround the white spiracle outlined 

 with black. 



The larva when full grown measures one and a 

 quarter inches in length, is of moderate stoutness, 

 cylindrical, with the head a trifle smaller than the 

 second segment, which is in turn a little less than the 

 third, the anal segment tapering a little behind. Its 

 ground-colour now is pale ochreous or pale brownish- 

 ochreous ; the head is delicately freckled and streaked 

 with dark brown down the front of each lobe ; the 

 second segment has a dark brown or brownish-grey 

 plate through which the fine dorsal and broader sub- 

 dorsal lines of ground-colour are visible ; on the rest 

 the dorsal line can be faintly discerned as a fine thread 

 of ground-colour running through the dorsal blackish 

 spots and ill-defined pear-shapes that follow them ; 

 both front and hind pair of black dots are now equally 

 distinct on the back of each segment, and a similar 

 dot is situated a little above each spiracle, which last 

 is whitish, faintly outlined with black ; a patch of dark 

 grey or blackish freckles anteriorly in the subdorsal 

 region, and some broken patches of lines of freckles 

 extending in curves to the spiracular region on each 

 segment, are now the only remains of the design 

 mentioned in the previous stage, this change having 

 been brought about by the scattering of the dark 

 atoms which before were confined in lines ; the belly 

 and legs are of the ground-colour. 



As will be seen from what follows, there is con- 

 siderable resemblance between this larva and some of 

 its congeners, but to my eye its most striking charac-
