EROTYLA. 89 



The following very interesting description of the brown variety 

 of the larva is given by Mr. J. Hellins in the " Entomologists' 

 Monthly Magazine," and is quoted in Mr. Buckler's work : 



" Hiibner's figures of this species leave me little that is new 

 to say about it. Still, I feel much indebted to Mr. Brown 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 i5th. 



" I potted for it a small plant of Convolvulus arvensts, 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 con- 

 tentedly during the first half of its fifty days' life, its longest 

 journey all that time not exceeding an inch and an 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 of the 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 is rich chocolate-brown ; dorsal line rather 

 darker, and edged with very fine paler lines ; sub-dorsal 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 some
