296 LEPIDOPTERA. 



tious of Dr. ^lason and Mr. S. J. Capper. In the collection of 

 the late Mr. F. Bond is one with the usually dark markings 

 pale drab tinged with green ; and in the Zoologid for 1862 

 is a record by ilr. W. E. Parsons of a specimen, taken near 

 Aylesbuiy, Bucks, of which the fore wings were milk-white, 

 and the hind of a delicate green colour, the silvery white spots 

 of the under side shining through on the upper side like gold. 

 On the wing at the end of July, in August, and sometimes 

 as late as the first week of September. 



Larva " olive green ; head large and black ; two white 

 spots on each side of the tenth and eleventh segments " 

 (Lang). " The larva is blackish grey mixed with rust colour, 

 having a double black line at the sides " (Berge). " Larva 

 dull green mixed with reddish, second segment white ; two 

 white spots near the bottom of the ninth and tenth segments " 

 (Duponchel, Stainton's Manual). '■ It has a large blackhead 

 and a cylindrical, olive-green body, with a linear white spot 

 on each side of the tenth and eleventh segments, very near 

 the ventral sm-face " (Newman, '• Hlibner's figure"). These 

 four descrijotions, though brief, indicate a tolerably wide 

 range of variation, if all are correct. Eliminating that of 

 Berge, which is obviously improbable, the discrepancies are 

 not so great, especially as Duponchel, in indicating the posi- 

 tion of the white spots, evidently counted the segments 

 exclusive of the liead. These white spots are undoubtedly 

 present in this as in the remaining larvae of the genus, since 

 Zeller. who evidently knew this larva, mentions them. They 

 would appear linear in Hlibner's figure from being really 

 situate on the under side. Attempts were made by jMessrs. 

 Buckler and Hellins to rear larvze from the eggs, without 

 result, exceiDt that the Eev. J. Hellins saw one larva making 

 its way out of the egg-shell at the end of March, and thus 

 proved that the eggs, which were deposited in the previous 

 August, remain in that condition through the winter. 



The larva is said to feed on Coronilla varia, Orniihopus
