16". The Small White Wave (Asthena ca,ididata). 



167. THE SMALL WHITE WAVE. The an- 

 ennae are simple in both sexes: the wings 

 are white, with seven waved transverse gray 

 lines on the fore wings, and four on the hind 

 wings : there is also a spot between the third 

 and fourth lines on the fore wings, and the 

 fourth and fifth lines are nearer together than 

 either of the others, especially as they ap- 

 proach the inner margin : on the hind margins 

 of all the wings is a series of black dots : the 

 antennas, head, thorax, and body are pure 

 white. 



The MOTH appears on the wing in May and 

 June, and is common everywhere. (The 

 scientific name is Asthena candidata.} 



168. The Waved Carpet (Asthena sylvata). 



168. THE WAVED CARPET. The antenna) 

 re simple in both sexes : the wings are pale 

 ray, with zigzag lines of a darker gray ; 

 lere are ten of these gray lines on the fore 

 rings, and four on the hind wings : the 

 space on the fore wings, between the fifth 

 and sixth of these lines, is greater than the 

 other interspaces, and has the appearance of a 

 pale, transverse band : the last of these lines, 

 situated on the hind margin, consists of a 

 series of long spots, and is not zigzag, but 

 follows the curved outline of the wing ; the 

 head, thorax, and body being of the same 

 colour. 



The MOTH appears on the wing in June, 

 and is very generally distributed in England, 

 and occurs in Ireland, in the counties Wicklow 

 and Galway. (The scientific name is Asthena 

 sykata.} 



169. Blomer's Rivulet (Asthena pulchraria). 



169. BLOMER'S KIVULET. The wings are 

 pale gray, the fore wings with two waved 

 raw-sienna bands near the tip, and very close 

 together ; the inner of these is bounded by a 

 black waved line ; on the costal margin are 

 four or five short, oblique, brown lines, and 

 on the hind margin is a row of long black 

 spots, following the curved outline of the 

 wing : the hind wings have a similar row of 

 spots on their hind margin : both fore and 

 hind wings have a number of beautifully 

 delicate, but obscure, transverse, zigzag mark- 

 ings. 



The MOTH appears on the wing in June, and 

 has been taken in the counties of Devon, 

 Somerset, Glamorgan, Gloucester, "Worcester, 

 Stafford, Derby, Lancashire, Yorkshire, and 

 Durham. (The scientific name is Asthena 

 pulchraria.} 



170. The Dingy Shell (Eupisteria heparata}. 



170. THE DLXGY SHELL. The antenna? are 

 very slightly ciliated in the male, simple in 

 the female : the wings are dingy yellow to- 

 wards the body, dingy brown towards the 

 hind margin ; the two colours are not marked 

 by any line of separation, but are blended 

 into each other : the paler part is marked by 

 three, four, or five transverse waved lines, 

 which are often very indistinct, and are 

 scarcely darker than the general colour of the 

 wing : the antennaa, together with the head, 

 thorax, and body, are of the same colour as 

 the paler part of the wings. 



The MOTH appears in June, and is common 

 in most of our English counties, but I think 

 does not occur in Scotland or Ireland. (The 

 scientific name is Eupisteria heparata.)
