mark on each segment, with the white spiracles on 

 their lower edges, brilliantly contrasted by a stripe of 

 bright yellow below, along the side ; the belly and feet 

 green ; the head and dull plate on second segment 

 brownish. 



There is a variety in which the ground-colour is 

 brown or olive-brown, the dorsal line strongly marked 

 as a double dark brown line vanishing at the hind part 

 of each segment in some, and in others running con- 

 tinuously through a darkish brown triangle or diamond 

 on each segment ; individuals occurring with either 

 form. 



The subdorsal appears as a series of oblique dark 

 brown streaks, each streak commencing a little on one 

 side of the segment in advance, and abruptly termi- 

 nated on the next by the hinder trapezoidal tubercular 

 dot ; the dots are black, and placed on small yellowish 

 specks. Along the side of each segment is a trian- 

 gular shape of dark brown, their bases bounded by the 

 black fusiform marks containing the white spiracles, 

 and immediately followed by a bright yellow stripe, its 

 lower edge gradually tinged with the brownish colour 

 of the belly and legs. (W. B., August, 1866 ; E.M.M., 

 November, 1866, III, 136.)

 Plate XCIV, fig. 5. 



Early in July, 1865, Mr. Doubleday kindly sent me 

 several examples of the larva of this species that had 

 been reared from eggs, and were fed with Polygonum 

 aviculare; there were several varieties in colour, but 

 not a green one, as quoted from Freyer in Stainton's 

 ' Manual.' 



They were full-fed early in August, and the moths 

 appeared from May 31st to June 4th, 1866, the next 

 year ; they were remarkably fine specimens. 



The larv89 were about an inch and a quarter to an
