BRITISH AND EUROPEAN BUTTERFLIES AND MOTHS. 



dark transverse lines on the fore wings, and 

 two on the hind wings, a submarginal line 

 edged with bluish grey on both sides, and a 

 dark central dot on all the wings. It flies 

 among bushes in June and July, and is found 

 in Southern Europe. 



A. rusticata, W. V. The Least Carpet 

 IS yellowish white with three transverse lines. 

 Zore wings with a broad blackish central band 

 and a similar blotch at the base of the costa. 

 The submarginal line is shaded on both sides 

 with darker. The fringes have dark dots on 

 the ends of the nervures and there is a similar 

 dot in the middle of each wing. It is found 

 in Central and Southern Europe in July. The 

 larva is light yellowish, with a black head and 

 a dark line on the back. It feeds on moss, 

 etc. in Spring. 



A. humiliata, Hufn. The Dark Cream 

 Wave is bone - coloured with three (on the 

 hind wings two) dark transverse lines, a sub- 

 marginal line shaded on both sides with darker 

 and central dots on all the wings. The 

 marginal line between the nervures is dark 

 and the fringes are without markings. The 

 costa of the fore wings is reddish purple. It 

 is common in most parts of Europe in July. 



A. dilutaria, Hiibn. is straw-coloured with 

 the same markings as humiliata but without 

 red on the costa of the fore wings. It is 

 found in Central Europe, except the West, in 

 July and August. 



A. holosericata, Dup. The Silky Wave 

 closely resembles humiliata, but is without the 

 central dot on the wings, or the red costa of 

 the fore wings and with only a thin dark 

 transverse line. It is found in Central and 

 Southern Europe in July and August and is 

 scarcer than humiliata. 



A. circellata, Guen. The Circillate Wave 

 is yellowish white, dusted with grey, with a 

 marginal row of black spots. Fore wings 

 with three sinuated transverse lines and two 

 slender ones beyond them, parallel to the hind 

 margins. Hind wings with three sinuated 

 lines of which the two outer correspond to 

 the two inner transverse lines of the fore wings. 

 It is found near Manchester in June. 



A. degeneraria, Hiibn. The Portland 

 Riband Wave is pale yellowish grey, tinged 

 with reddish on the costa and towards the 



base of the fore wings. There are three grey 

 transverse lines, the space between the two 

 inner of which forms a dark grey band, almost 

 obscuring the blackish central spot. It is 

 found in Southern and Western Europe, the 

 Isle of Portland being the only locality in this 

 country. 



A. inornata, Haw. The Plain Wave is 

 reddish yellow, sometimes merging into olive- 

 green, with a silky lustre and slightly dusted 

 with darker. The transverse lines and central 

 shade are very faint. The posterior transverse 

 line is slightly notched on nervure 6. The 

 marginal line is rarely darker between the 

 nervures and the fringes. There is a central 

 dot on all the wings. It is found in most 

 parts of Europe in July. 



A. deversaria, Herr. - Schaff. resembles 

 the last species, but the ground is of a 

 clearer straw-colour. The submarginal line is 

 uniformly edged with darker on both sides. 

 Towards the base there is sometimes a den- 

 tated band extending to the third transverse 

 line. It is found in Southern Europe in July. 



A. aversata, Linn. The Riband Wave 

 is greyish yellow, slightly shining, dusted with 

 black. There are three (on the hind wings 

 two) narrow dark transverse lines, the last 

 interrupted on nervure 6 of the fore wings 

 and forming almost a right angle. The sub- 

 marginal line is shaded with darker, espe- 

 cially towards the base. The marginal line is 

 well defined and darker between the nervures. 

 There are central dots on all the wings, which 

 are placed before the middle transverse line 

 on the fore wings and behind it on the hind 

 wings. The space between the second and 

 third transverse lines forms a dark band, except 

 in var. spoliata, Stand. It is found m woods, 

 and is one of the commonest species of the 

 genus, being widely distributed throughout 

 Europe in July. The larva is brown, lightest 

 on the ninth segment and darkest from the 

 fifth to the eight, with dark transverse streaks 

 on the middle joints and white streaks on the 

 sides. On both sides of the double dorsal 

 line are angular hooks with their points directed 

 forwards. It lives in May and June on Genm 

 urhanum and other low plants. The pupa is 

 brown, and is enclosed in a loose cocoon, 

 between the leaves of the food-plant.
