Agrophila SULPHURALIS. 

 Plate 0, fig. 5. 



Hubner's figures of this species leave me little that 

 is new to say about it ; still I feel much indebted to 

 Mr. T. Brown, of Cambridge, for enabling me to rear 

 a larva which Mr. Buckler has figured. 



Unluckily, although the moth had laid several eggs, 

 they all perished in the post-office save one, and the 

 single larva did not live to become a pupa, having been 

 hatched on June 25th, and dying on August 15th. 



I potted for it a small plant of Convolvulus arvensis, 

 and on two little shoots of this, bearing in all not 

 more than five or six very small leaves, it fed and 

 grew and moulted contentedly during the first half of 

 its fifty days' life, its longest journey all that time 

 not exceeding an inch and a half. 



Had the other eggs escaped squashing on their 

 journey, probably I might have had the pleasure of 

 seeing both the varieties which Hiibner figures, but the 

 green one yet remains a desideratum ; my single larva 

 was his brown variety. 



When first hatched, it was a dingy-grey little 

 looper, with a black transverse dorsal hump on each 

 of the four middle segments, but at each moult these 

 humps became less, till at last there remained nothing 

 but the usual dorsal dots, black and distinct, and 

 these too afterwards disappeared. When full-grown 

 the larva is about an inch long ; the legs twelve ; the 

 body cylindrical, thickest at the fourth segment ; the 

 segmental divisions deeply indented; when at rest 

 the middle segments are generally arched, and the 

 head bent down. The colour a rich chocolate-brown; 

 dorsal line rather darker, and edged with very fine 

 paler lines ; subdorsal line also darker, but scarcely 

 visible ; spiracular stripe broad, of a pale yellow, and 

 with a fine brown thread running throughout its 

 length; immediately after the last moult there were
