BOARMIDJE—MACARIA, 373 



while a specimen in the collection of Mr. S. J. Capper is 

 almost devoid of the usual markings. 



On the wing in May and the beginning of June, and as a 

 partial second generation in July or August. 



Larva smooth, elongated, very slightly stouter behind ; 

 head rounded, pale green, with a large cloudy black spot on 

 each lobe ; body extremely pale green, with faint longi- 

 tudinal parallel red-brown lines, and upon the sides of the 

 fourth, fifth, and seventh segments a large purple-brown

 sallow, and alder. 



Pupa rather slender, stoutest in the middle from thicken-

 appressed ; antenna-covers ornamented with broad cross- 

 sculpture, which seems as though arranged over pectinations; 

 dorsal region much pitted, except the hinder edge of each 

 segment, where is a narrow smooth band ; all these parts 

 dark chestnut, except the wing-covers, which are darker ; 

 abdominal segments dark purple-brown, strongly pitted in 

 broad bands ; cremaster small, conical, armed with a pair of
