SPHINGip^. 5 



rosy portion; hind wings pale brownish or purplish grey 

 with a whitish central lunate spot towards the costa, and a 

 succession of dark-brown or reddish-brown lines throughout. 

 Slightly variable in the darkness of the brown shades and 

 Imes of the fore wings, and in the presence or absence of 

 rosy or purplish bloom, but otherwise very constant. Speci- 

 mens however occur, rarely, in which the hind wings are 

 almost or entirely destitute of rosy colour, being of a dull 

 yellowish instead. Mr. Sydney Webb has specimens with 

 the fore wings of a putty colour, with the usual markings, 

 and Mr. Charles Briggs one in which the shades and marbling 

 of the fore wings are nearly absent, but the lost colour seems 

 concentrated in the triangular spot which lies against the 

 outer line. Another curious aberration is recorded, in which 

 the ocellus of the hind wings is replaced by a triangular dark 

 spot. 



Double brooded, appearing in May and June, and again 

 in August, or even September, though the second emergence 

 is probably but partial, and rarely occurs in the more 

 northern portion of its range, while the individuals of the 

 first emergence sometimes remain in pupa more than a 

 month beyond their usual date. 



Larva stout, rather tapering in front, head triangular, 

 pointed above, face flattened ; skin of the body rough with 

 minute raised dots, wrinkled transversely; having on the 

 twelfth segment a long, slightly curved, sharply pointed 

 horn inclined backwards. Bright apple green, whitish green, 

 or bluish green, with the raised dots white ; on each side of 

 each segment, from the fifth to the eleventh, is an oblique 

 white stripe edged above with dark green, each extending 

 beyond its segment both in front and behind, and the seventh 

 passing across the eleventh and twelfth segments and reachincr 

 thehorn upon the latter; another similar stripe, less oblique, lies 

 along the side of the second to the fourth segments ; spiracles 

 yellowish-white or pale pink, surrounded with pinkish-brown
