BRITISH MOTHS. 



171. The Welsh Wave (Venusla camMcarit). 



171. THK WELSH WAVE. The antennae 

 are ciliated in the male, simple in the female ; 

 the wings are pale gray : the fore wings have 

 ten zigzag, brown, transverse lines, which 

 differ much in darkness of shade ; near the 

 middle of the wing there is a delicate black 

 crescent-shaped mark : on the hind wings, the 

 markings are few and delicate : the head, 

 thorax, and body are dark gray. 



The EGGS are laid about the 17th of July, 

 and the young CATERPILLARS emerge about the 

 27th. They feed on mountain ash or rowan 

 tree (Pijrus aucuparia), and when full-fed 

 spin together a division of the leaf of the 

 food-plant, and change to a CHRYSALIS. 



The MOTH appears on the wing about Mid- 

 summer, and is said to have occurred in Mon- 

 mouthshire, but is chiefly an inhabitant of the 

 northern English counties, Cheshire, Lan- 

 cashire, the Lake District, Yorkshire, and 

 Northumberland. Mr. Birchall took it at 

 Powerscourt, in Ireland. (The scientific 

 name is Venus i a c>n>ibricaria.} 



172. The Bright W;ive (Acidulia ochrala}. 



172. THE BRIGHT WAVE. The antennae 

 are simple in both sexes : the wings are dingy 

 fulvous ; the fore wings have four transverse 

 lines of a darker hue, and the hind wings 

 have two; these markings are only a shade 

 darker than the general hue of the wing, and 

 are not all of the same hue, the two nearest 

 the middle of the wing being obviously darker 

 than the rest: the head, thorax, and body 

 are of the same colour as the winss. 



This MOTH appears on the wing in June : it 

 is only found on the coasts of Kent and Essex. 

 (The scientific name is Acidalia ochrata.} 



173. The Tawny Wave ( Acidalia rubricatci). 



173. THE TAWNY WAVE. The antennae arc 

 ciliated in the male, simple in the female : the 

 wings vary in colour, some specimens being of 

 a grayish green, others of a bright purple ; 

 but in both instances there are three trans- 

 versely oblique darker lines on the fore wings 

 and two on the hind wings. 



The MOTH appears on the wing in June, 

 and has only been taken in Surrey, Essex, 

 Norfolk, and Yorkshire. (The scientific name 

 is Acidalia rubricata.} 



H4. The Single-doited Wave (Aciihinn smhilulu}. 



174. THE SINGLE-DOTTED WAVE. All the 

 wings are pale wainscot-brown ; the fore 

 wings having two waved and interrupted 

 brown lines near to, and parallel with, the 

 hind margin : the costal extremity of the first 

 of these lines consists of a few black dots, that 

 of the second is indistinct, but near the inner 

 margin they become broad and distinct, almost 

 forming a blotch ; near the centre of the wing 

 is a dark brown dot, and near the base are 

 several obscure brown markings: the hind 

 wings have a central dark spot, like the fore 

 wings, and three or four very interrupted, 

 waved, transverse lines: there is also a ro\v 

 of about eight dark brown spots at the base 

 of the fringe on each wing : the head, thorax, 

 and body are of the same colour as the wings. 



The CATERPILLAR is long, slender, and tapers 

 towards the head; its colour is a pale drab, 

 with a darker medio- dorsal stripe, and a p:Jer,
