pnvcrrin.E—ACROBAsis. 5 



•other deciduous trees; lading itself within a folded leaf, 

 eating the substance between the veins into holes, and so 

 skeletonising the leaf, after which it removes to another, 

 usually drawing the upper surfaces to within a quarter of 

 an inch of each other by means of lightly spun silken 

 threads and webbing. 



Pui'A slender and of the ordinary shape ; the surface of 

 the abdominal rings slightly punctated, though smooth at 

 the divisions; the tip ending with two curly-topped spines; 

 the spiracles minute but rather prominent and black ; 

 remaining surface shining dark reddish-brown. In a brown 

 cocoon on or in the ground. (W. Buckler.) The winter Ls 

 passed in cocoon, but whether as larva or pupa is not clearly 

 ascertained. 



The moth loves to hide in trees and in very tali bushes, 

 sometimes in hedges, especially in dense bushes such as 

 blackthorn. It is by no means commonly to be taken, yet is 

 very widely distributed in woods and open-timbered country, 

 being recorded from all the southern, eastern, and south- 

 western counties of England to Worcestershire and Cheshire ; 

 TOiuch more rarely from the Midlands, but apparently to be 

 found in suitable spots throughout to Yorkshire and Cum- 

 berland ; yet I find no record in Scotland or Ireland, and in 

 Wales only my own in Pembrokeshire, where it was rare. 

 Abroad it is generally distributed and common in Central 

 Europe, and is found in Dalmatia and Russia. 



Genus lU. ACROBASIS. 



Antennae simple, but the second joint rather bent, and a 

 large tuft of scales is at the inner side of the basal joint in 

 the male ; palpi slender, up-curved ; fore wings elongated, 

 not very narrow, discal cell somewhat trigonate ; hind wings 

 ample, with the cell short and the cross-bar angulated ; legs 

 moderately long.
