BRITISH MOTHS. 



have four indistinct and zigzag, pale, waved 

 lines, and a very distinct black dot between 

 the first and second, counting from the base 

 of the wing : the head and thorax are brown 

 of the same hue as the bar on the fore 

 wings ; the body is variegated with the two 

 colours, white and brown. 



The MOTH appears in July, and is very 

 abundant in all the hedges about Darent 

 Wood, in Kent ; it is also said to have 

 occurred in the Isle of Portland. (The 

 scientific name is Acidalia rusticala.) 



179. The Dark Cream Wave (Acidalia inter jectaria). 



179. THE DARK CREAM WAVE. All the 

 wings are very pale wainscot-brown, some- 

 what approaching to a yellow-ochre tinge; the 

 fore wings have the costal margin shaded 

 with brown, and five pale, transverse, zigzag 

 lines, between the second and third of which 

 is a central black spot ; the two lines between 

 this spot and the base of the wing approach 

 each other very nearly in the middle, and I 

 have one specimen in which they are abso- 

 lutely united: the hind wings have four of 

 these pale, waved, transverse lines, and a black 

 spot between the second and third, counting 

 from the base of the wing ; along the hind 

 margin of all the wings is a row of linear, dark 

 brown spots, perhaps better described as a 

 series of short dark brown lines ; arrange'! end 

 to end, and alternating with these lines, is a 

 series of dots in the fringe ; these dots, how- 

 ever, are not constant, and are only to be de- 

 tected in very fine and fresh specimens : the 

 head, thorax, and body are pale wainscot- 

 brown, exactly of the same colour as the 

 wings. 



The MOTH appears on the wing about 

 Midsummer, and has been taken in Devon- 

 shire, Gloucestershire, Buckinghamshire, Cam- 

 bridgeshire, and Cheshire. (The scientific 

 name is Acidalia interjectaria.) 



180. The Silky Wave (Acidalia holosericata). 



180. THE SILKY WAVE. All the wings 

 pale wainscot brown, somewhat approaching 

 to yellow-ochre ; the fore wings are sprinkled 

 along the margin with extremely minute, 

 dark brown dots, and have five transverse and 

 rather waved lines, of a darker hue than the 

 ground colour of the wing ; the hind wings 

 have the same number of waved lines as the 

 fore wings, which, in all respects, they closely 

 resemble : the head, thorax, and body are of 

 the same colour as the wings. 



The MOTH appears on the wing in July, 

 and has been taken in Surrey, Gloucester- 

 shire, and Worcestershire, but not in Ireland. 

 (The scientific name is Acidalia holosericata.) 



181. The Small Dusty Wave (Acidalia incanaria). 



181. THE SMALL DUSTY WAVE. All the 

 wings are dingy white, sprinkled all over 

 with minute black dots ; the black dots are 

 somewhat symmetrically arranged, forming 

 several smoke-coloured, transverse, waved, 

 and very indistinct lines ; each of the four 

 wings has also a central black spot : along the 

 hind margin of all the wings is a series of 

 short, dark, smoke-coloured lines, placed end 

 to end, and alternating with these is a row of 

 dark dots in the fringe : the head, thorax, 

 and body are almost white, but, like the 

 wings, sprinkled with minute dark specks. 



The MOTH appears on the wing in July, 

 and occurs in all our English counties, and iu 

 some places in Scotland. Mr. Birchall says 

 it is common in Ireland. (The scientific 

 name is Acidalia incanaria.)
