58 XYLOPHASIA POLYODON. 



it had grown in size, and was much paler, especially 

 below the line of spiracles, looking even more like 

 polyodon than at first. 



This larva continued to grow and became gradually 

 paler and greyer, more like polyodon ; the pale streaks 

 between the trapezoidal spots became visible, and the 

 pale dots more transversely elongate than usual. 



On June 8th I found it had changed to a pupa. 

 The moth X. polyodon emerged July 9th. (W. B., Note 

 Book II, 191.)

 Plate LXIII, fig. 3. 



On the 19th of September, 1876, I received from 

 Mr. W. R. Jeffrey a small Noctua larva, which he had 

 found in a folded brown leaf of Stachys sylvatica, and 

 which had moulted a day or two before the 18th. It 

 was only three- eighths of an inch long when it came, and

 spiracular region, and was remarkable from having on 

 either side of the second segment on the light brown 

 shining plate a conspicuous and very dark brown 

 spot. 



The larva refused to eat Stachys sylvatica and all 

 other kinds of food until grass was supplied, and then 

 it began to feed, and on the 27th it moulted and again 

 took to grass, seeming to prefer Dactylis glomerata to 

 either Air a c&spitosa or PhaJaris arnndinacea , and by 

 October 14th it had become a trifle over three-quarters 

 of an inch long, and of moderate stoutness ; the head 

 brown and shining, plate on the second segment brown, 

 finely divided by a very thin dorsal and broader sub- 

 dorsal lines of a pale yellowish ; below these last the
