1 1 2 LEPID OP TERA . 



a specinieu in ilr. F. Bond's collection in the possession of 

 Mr. Sydney A\'el)b. It is wholly white, except that the 

 ordinary darlc markings are faintly indicated in pale yellowish- 

 brown. 



On the wing in July and August. 



Lak\a loiis^, slender, and smooth, without humps; head 

 about equal in width to the second segment ; the thirteenth 

 is terminated by twd, rather long, parallel points beneath 

 the anal tlap ; head and body apple-green; dorsal strijie 

 l>road, darker than the ground colour; on each side of this 

 is a yellowish-green or whitish-green stripe. (E. Newman.) 

 The IJev. J. llellins says that when very young it is of a 

 gaudy orange-colour, with a dark head. 



A]>ril to June ou alder: less frecjuently on birch, black- 

 thorn, plum, crab, and apple, and apparently sometimes 

 oa cherry. 



PtTA slender, green, or brownish-green ; ending in a 

 slender spike, (llofmann.) In the corner of a leaf folded 

 over and spun down for the purpose. 



The winter is jiassed in the egg-state. 



This moth is a very attractive little creature ; it has a 

 most curious trick of starting up from a tree in which it mav 

 be sitting, on the approach of any person, and dancing A/«'«?y/,v 

 him at a gcod height in the air as though actuated by the 

 liveliest curiosity, but keeping at no great distance from its 

 favourite trees. These are usually alders, and in the latter 

 part of the afternoon towards sunset they are greatly 

 enlivened by the numbers of these pretty snow}--lookinL;' 

 moths dancing about and around them. Mr. Sydnej' Webb 

 tells me that in Kent, when no alders are near, he sees it 

 Hying in the same lively manner about every cherry-orchard. 

 There certainly is also a night flight, when it will occasion- 

 ally visit flowers such as those of the hemp-agrimony ; but 

 late at night it probablv settles down to sit. ^ith wings
