darker. It is found in most parts of Central 

 and Northern Europe in June and July. The 

 larva is green, lighter above, with sinuated 

 yellowish longitudinal lines. It feeds on Vac- 

 cinium tdiginosmn in May. 



P. ni, Hiibn. The Silver V Moth. Fore 

 ■wings light ashy grey, varied with darker, with 

 a silver V and a small silver spot behind it. 

 The submarginal line is light and interrupted, 

 with fine black sagittate spots above. The 

 hind wings are whitish at the base. It is 

 found in South Europe and has been taken 

 once in Devonshire. The larva feeds on low 

 plants. 



P. ain, Hochenw. Fore wings light grey 

 marbled with black, with two distinct double 

 lines, and the stigmata finely edged with darker. 

 There is a very regular fine silvery Y mark 

 in the position of the claviform stigma, and the 

 submarginal line is sharplj' zigzag. The hind 

 wings have the fringes yellow at the base, 

 white at the tip and black through the middle. 

 It is found in July and August in the Swiss 

 and Bavarian Alps and in the Riesengebirge. 

 The larva feeds on Vaccinium in May and June, 

 and it is said also on Pinus larix. 



P. hochenwarthi, Hochenw. Fore wings 

 reddish grey with the central area, e.xcept the 

 costal margin, darkest. The two transverse 

 lines are distinct and double. The silver Y 

 has the branches very slightly open and the 

 extremity straight. The submarginal line is 

 only slightly zigzag. The hind wings have a 

 yellow marginal line. It is common in moun- 

 tain pastures on the Alps of Switzerland and 

 Bavaria and in Scandinavia, and appears in 

 July and August. The larva is reddish brown 

 with a yellowish dorsal and lateral line and 

 faint light sinuated lines between. It feeds on 

 Vaccinium and other low plants in May and 

 June. 



P. devergens, Hiibn. Fore wings dark 

 grey, slightly suffused with violet-red. The 

 central area is darkest and the two trans- 

 verse lines are distinct and double. The 

 silver Y is thick with very indistinct branches.

FAMILY 



HELIOTHID^E. 



Slender middle-sized moths, with beautiful 

 colouring and delicate forms. The antennae 

 are setiform in both sexes, the thorax generally 

 clothed with fine wool and the eyes naked 

 and not ciliated except in anarta. Tlie pro- 

 boscis is spiral. The larvae have sixteen legs, 

 and scattered hairs on punctiform warts. They 

 live on low plants, feeding on the flowers and 

 seeds, and assume the pupa in the ground. 

 The moths fl)' in the sunshine. 



Genus Anophia, Guen. 



Thorax covered with smooth scales; abdomen 

 tufted. Fore wings expanded, resembling 

 pliisia in shape and in the long fringes of the 

 hinder angle. Hind wings rounded. The 

 larvae are smooth, with slightly stunted prolegs, 

 and feed on Convolvulus. The only species is: — • 

 A. leucomelas, Linn. Fore wings uni- 

 form brownish black with yellowish markings; 

 hind wings white with a broad black mar- 

 ginal band and the fringes white, except in 

 the middle and at the anal angle, where they 

 are black. It is found in Southern and East- 

 Central Europe in June and July. The larva 

 is brownish with three orange-coloured dorsal 

 and a light lateral line. It feeds on Convolvulus 

 in July and August, and remains hidden during 

 the day. 



Genus ^dia, Hiibn. 



Antennae finely ciliated in the male. This 

 genus resembles the last, but the wings are 

 much shorter and have broader fringes. The 

 abdomen is a third shorter and only slightly 

 projects beyond the anal angle. It has a 

 truncated anal tuft but no tufts on the sides. 

 The larvae are slender and live on Convolvulus, 

 hiding during the day. They pupate in a 

 dense earthen cocoon. During the day the 

 moth rests with wings sloping; and flies about 

 flowers in the evening. The only species is: — ■ 



JE,. funesta, Esp. Fore wings dark brown, 

 the two transverse lines deep black, finely 

 edged with rusty brown, with a pale rusty 

 yellow spot at the costal border of the central 

 area, which extends as far as the middle of 

 the reniform stigma. The round orbicular
