BRITISH AXD EUROPEAN BUTTERFLIES AXD MOTHS. 



by a common stem from 7; 10 rises from it 

 also; II and 12 lie side b}- side, close together, 

 and in tvavaria they are connected. Nervures 

 3 and 4 and 6 and 7 of the hind wings are 

 separate, and 5 is slender and hardly visible. 

 The wings are kept flat when at rest. 



H. wavaria, Linn. The V Moth. PI. 

 XXX. fig. 7. is common in gardens through- 

 out Europe in July. The larva is bluish green 

 with black warts 'and short hairs. It has a 

 broad pale yellow lateral and a double fine 

 white dorsal line. It lives on gooseberry and 

 currant in May and June. The pupa is red- 

 dish brown, thick in front with a terminal 

 point. It forms a fine cocoon on the ground. 



H. brunneata, Thunb. The Rannoch 

 Geometer is ochre-yellow tinged witli rose- 

 colour. Fore wings with three or four parallel 

 transverse lines; tliese are distinct in the female, 

 but faint in the male, and are expanded into 

 spots on the costa, and the third is slightly 

 macular in front. The marginal line is in- 

 complete and darker. The fringes are chequered, 

 the hind wings with two or three usually in- 

 distinct transverse lines. The marginal line 

 and fringes are as on the fore wings. Under 

 side as above, but with the transverse lines 

 more prominent. It is widely distributed in 

 Central and Northern Europe in July, and is 

 found at Rannoch in Scotland. The larva is 

 violet, with a few white dorsal lines and a 

 broad yellow lateral line. The head, belly, 

 and legs are flesh-coloured. It feeds on bil- 

 berry ( Vaccinhim uligiiwsiiin). The pupa is 

 subterranean. 



Genus Diastictis, Hiibn. 



]\Iiddle-sized moths with pointed, waved 

 wings, but otherwise like the last genus in 

 appearance. Palpi horizontal and prominent, 

 front with a horizontal pointed crest. Proboscis 

 spiral; eyes large. Antennse with moderately 

 long ciliated pectinations in the male, dimin- 

 ishing in length towards the tip, serrated in 

 the female. The hind tibiae have two pairs 

 of spurs. The only species is: — 



D. artesiaria, W. V. This is ashy grey, 

 fineh- dusted with brown. Fore wings with 

 two straight transverse lines, the anterior line 

 and the central shade being indistinct, and the 

 posterior finely double, filled out with yellowish. 



There is a dark central spot and a dark mar- 

 ginal area. Near the apex is a small dark 

 spot, there is a slight submarginal line and 

 a scarcel}^ darker marginal line. The fringes 

 are without markings. Nervures i to 4 are 

 yellowish. The hind wings are darker towards 

 the hind margins with a faint central spot 

 and an indistinct central line. It is found in 

 July in Central Europe except the North-West, 

 but is not common. The larva is bluish green 

 with fine white longitudinal lines and a yellow 

 lateral one. It feeds on willow. The bright 

 dark brown pupa is enclosed between leaves 

 which have been spun together. 



Genus Phasiane, Dup. 



Middle-sized, slender moths with broad, 

 almost rectangular fore wings, rounded at the 

 hinder angle ; and rounded hind wings, without 

 a groove in the males. Body, legs, and palpi 

 smoothly scaled, the last with a short obtuse 

 terminal joint which only slightly projects. 

 The antennae are setiform in both sexes, or 

 notched in the male [glarearia). Hind tibiae 

 with two pairs of spurs. Nervures 3 and 4, 

 and 6 and 7 of all the wings are separate, 

 8 and g have a stalk rising from 7, 10 rises 

 from the front border of the discoidal cell. 

 Nervure 5 of the hind wings is wanting. 



P. petraria, Hiibn. The Brown Silver 

 Line is pale grey tinged with reddish. Fore 

 wings with the hind margin slightly waved 

 below the apex, with two straight parallel, 

 fine sharply defined dark transverse lines, 

 edged with white towards the base and not 

 extending to the costa. There is a central 

 spot. The submarginal line is slightly sinuated, 

 white somewhat suffused with darker towards 

 the base. There is a dark marginal line and 

 banded fringes. The hind wings are rather 

 paler and more heavily dusted towards the 

 hind margins. The posterior transverse line 

 is only indicated by a faint dark central spot. 

 The marginal line and fringes are as on the 

 fore wings. It is common in Central and 

 Southern Europe from May to July. The 

 larva is olive-green with double longitudinal 

 chocolate-brown lines, one pair on the back 

 and three pairs on the sides. The spiracles 

 are black with a pale line below them. It 

 feeds on fern [Pteris aquilina).
