BRITISH AXD EUROPEAN BUTTERFLIES AXD MOTHS. 



a dark straight transverse line running from 

 the apex beyond the middle of the inner 

 margin, which is indistinct on the hind wings. 

 It is found in Central Europe in June. The 

 larva is greenish, darker on the belly with 

 dark incisions and a white lateral line with 

 two red ones below it. It feeds on yarrow 

 {Achillea) and Sarothamnns, etc. The pupa has 

 a slight cocoon on the ground. 



A. ochrearia, Rossi. The Yellow Belle 

 is yellowish slightly dusted with grey. There 

 are two dark transverse lines on the fore wings, 

 the anterior of which is curved and slightly 

 serrated, and the posterior somewhat bent 

 and more oblique, and continued on the hind 

 wings. There is a dark central spot. It is 

 found in Southern and Western Europe in 

 !May and August. The larva is whitish with 

 a slight reddish tinge, with two reddish grey 

 lines on the back and one on the sides, as 

 well as two spines on the terminal segment. 

 It feeds on yarrow. 



A. strigillaria, Hiibn. The Grass Wave 

 is light grey heavily dusted with brown or 

 yellowish grey. Fore wings with three, hind 

 wings with two mere or less distinct parallel 

 transverse lines curved towards the hind mar- 

 gins. There is a dark marginal line on all 

 the wings, which is strongly curved inwards 

 between nervures 4 and 6 of the hind wings, 

 and the fringes are banded with darker. It is 

 common in Central Europe in June and July. 

 The larva is light grey with a paler dorsal 

 stripe, bordered with a black zigzag line and 

 expanded into black spots on each segment. 

 There is a brown lateral stripe and two white 

 lateral spots in front, and an obtuse hump on 

 each segment. It feeds on broom and hiber- 

 nates. The pupa is slender, reddish brown 

 with greenish wing-cases, and forms a cocoon 

 on the ground. The variety grisearia, Stand, 

 is lighter with dark streaks. It is found in 

 Saxony, Pomerania, etc., but is scarcer than 

 the type. 



Genus Aplasia, Hiibn. 



Small uniformly coloured moths, dusted with 

 darker, with rounded wings, and slightly jiro- 

 jecting angles, and a slender body. Palpi 

 curved, with depressed scales, slightly pro- 

 jecting beyond the head and with a short 



tapering terminal segment. Proboscis spiral. 

 Antennae thick, setiform, and very slightly 

 ciliated in the male. Hind tibiae with two 

 pairs of short spurs. Nervures 3 and 4 are 

 separate; 6 and 7 of the fore wings rise from 

 a point, S rises from 7, g from 8; 10 is free, 

 forms the subcostal nervure, touches the fork 

 of 7 and 8 and is connected with the anterior 

 edge of the discoidal cell; 11 has only a short 

 stalk running from 10 to the costa. Nervures 

 6 and 7 of the hind wings are stalked, 8 lies 

 at first on the anterior edge of the discoidal 

 cell, whilst 5 is as thick as the others. The 

 only species is: — 



A. ononaria, Fuessl. The Rest-harrow 

 Moth. This is yellowish thickly dusted with 

 reddish brown, with a reddish purple indistinct 

 marginal band and generally a faint transverse 

 band, most distinct near the base of the fore 

 wings. There is a central spot on all the 

 wings, more distinct on the under side. It is 

 found in Central and Southern Europe from 

 May to July, and has been taken at Folkestone. 

 The larva is short, fusiform, pale dirty green, 

 dotted with black and covered with short 

 grey hair, with a row of black dots on the 

 back and a yellow waved lateral line. It 

 feeds on rest-harrow {Ononis). The pupa is 

 greenish yellow with brownish wing-cases, and 

 a white cocoon. 



Genus Lythria, Hiibn. 



Small moths with short triangular hind 

 wings, with rectangular apices and anal angle, 

 with the apex produced so that the hind mar- 

 gin appears almost straight. Palpi drooping 

 with a tapering projecting terminal segment. 

 Proboscis stout. Antennae with long thin 

 ciliated pectinations in the males, which cease 

 before the tip, setiform in the females. Legs 

 short, hind tibias one -third as long as the 

 femora, with two pairs of spurs. Nervure 2 

 of the fore wings rises from the middle of 

 tlie inner margin, 3 in front of, 4 from the 

 lower angle, and 6 from the upper angle of 

 the discoidal cell; 7 and 11 rise from the tip 

 of the undivided appendicular cell; 8 from the 

 middle of 7, 9 and 10 in succession from 8, 

 and 12 runs free to the subcostal nervure. 

 Nervure la of tlic hind wings terminates close 

 to the base, ib on the inner margin in the
