BRITISH MOTHS 



171. The Welsh Wave (Venusiacanibricaria). 



171. THE 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 thei-e 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 (Pyrus 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 it is said to have occurred in Mon- 

 mouthshire, but is chiefly an inhabitant of 

 the northern English count is, Cheshire, 

 Lancashire, the Lake District, Yorkshire, 

 and Northumberland. Mr. Birchall took it 

 at Powerscourt, in Ireland. (The scientific 

 aame is Venusia cambricaria.) 



172. The Bright Wave (Acidalia ochrata). 



172. THE BRIGHT WAVE. The antennas 

 are simple in both sexes : the wings are dingy 

 hilvous; the four wings have four transverse 

 line* 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 tho -**ugs. 



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 rubricata). 



173. THE TAWNY WAVE. The antennae 

 are 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 

 tranversely 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). 



174. The Single-dotted Wave (Acidalia scutulata). 



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 

 marginthey 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 row 

 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 strW- .*i1 a paler.
