the division between the fourth and fiftli ; through this runs 

 a central thread of yellow, bordered with an edging of brown, 

 darker than the patcli, which has also a darker line running 

 along just outside its outer curved edge; about tlie middle 

 of the sixth segment commences a pair of lateral blotches 

 which run through the seventh and eighth, of either rose- 

 pink or crimson-brown, having a streak of darker brown just 

 in the place of the subdorsal line; these blotches have 

 waved edges which nearly meet at the segmental divisions 

 both above and below; through the fifth to the eleventh 

 segments inclusive there is no dorsal line whatever, but on 

 the twelfth and l)eginning of the thirteenth, in the place of 

 the dorsal line, is a broad stripe of rose-pink bearing at each 

 end a dark sjiot of crimson-brown ; ajiiracles obscure, round, 

 greenish-yellow on the ground colour, brown on the coloured 

 blotciies ; so too with the usual raised dots ; on the ground 

 colour the\" are scarcely to be seen, on the blotciies they 

 become prominent, shining, and dark brown. 



One vai-iety is greenish-yellow all over, with no markings 

 whatever ; another has the blotch on the second to fourth 

 segments, but only a dot on the twelfth, and no other mark- 

 ings ; a third has a dark dorsal spot on the middle of the 

 fifth segment ; and another a similar spot on the sixth almost 

 connecting the lateral blotches. (W. Buckler.)
