BRITISH AXD EUROPEAN BUTTERILIES AXD MOTHS. 



abdomen is greyish brown. It appears in 

 April and May in Southern Europe, and is 

 found resting on the trunks of elm trees. The 

 larva is pale green or brownish gre\% with a 

 yellow longitudinal dorsal stripe, having a black 

 line through the middle, an orange line on 

 the sides, and a black elevation on the fifth, 

 and another lower down on the last segment 

 but one. The bodj' terminates in a brown 

 fork. It feeds on elm. The pupa, which is 

 dark brown, with two stiff tufts of hair at the 

 e.xtremity, is subterranean. 



Genus Hybocampa, Led. 



Fore wings with twelve nervures ; ii rises 

 from the subcostal nervure, 7 from 6, 8 from 

 7, g from 8 near the apex, and 10 from 7. 

 There is no appendicular cell. Hind wings 

 with eight nervures, 6 and 7 rising from a 

 common stalk. The fringes are brown, with 

 white nervures. The tegulse have an elevation 

 on their inner angle. The antennse are bare 

 at the tip.- The ocelli are absent, and the 

 larvae have no anal fork. They pupate in a 

 dense cocoon on trees. 



H. milhauseri, Fabr. Fore wings pale 

 grey, with a band of yellow spots across 

 the middle, a double dark transverse stripe, 

 and a dark shade. On the inner margin are 

 two black spots. The nervures are dark brown. 

 The hind wings are white, with a blackish 

 spot near the anal angle, crossed by a pale 

 oblique line, and with a faint lunula in the 

 centre. The thorax is blackish, with white 

 tegulag. The abdomen is blackish. The moth 

 is widely distributed in woods in Central and 

 Southern Europe, but is scarce everywhere. 

 It appears in May and June. The caterpillar 

 is green, granulated with whitish, and has a 

 red pointed wart on each of the si.x middle 

 segments, the first of which has two points 

 and oblique red stripes on the sides. The 

 head is red. It feeds on oak, beech, elm, and 

 birch in July and August. The firm cocoon 

 is found on the trunks of trees, which it much 

 resembles in colour. 



Genus Notodonta, Ochs. 



Fore wings narrow, w'ith rounded angles 

 and twelve nervures, nervures 6 and 7 rising 

 close together, 8 from 7, g and 10 from 8. 



The inner margin has a tooth-like scaly pro- 

 jection in the middle. The antennae are bi- 

 pectinated in both sexes, or else dentated in 

 the female. There are no ocelli. The hind 

 tibiae have middle spurs. The thorax and legs 

 are clothed with W'Oolly hair. The larvae are 

 smooth and flat, or furnished with prominences. 



N. tremula, W. V. The Swallow Pro- 

 minent. The wings are white; the fore wings 

 with three longitudinal black stripes in cells 

 6, 7, and 8, and another running parallel to the 

 inner margin from the middle of the base 

 to the submarginal line. This stripe is dentated 

 on the inner side, has a white outer edge, and 

 is suffused with brown in front, and crossed 

 by white nervures towards the costa. Above 

 the tooth-like scaly projection on the inner 

 margin is a small longitudinal black streak. 

 The hind wings have a dark brown spot at 

 the inner angle, crossed by a white transverse 

 line. The antennae are rust-coloured, and are 

 bipectinated in both sexes. The head and 

 thorax are greyish brown, and the abdomen 

 yellowish brown. The moth appears in Spring 

 and again in July and August in open 

 places in woods, and is common in Central 

 Europe. The larva is slender, shining reddish 

 brown or violet, with a yellow lateral line, 

 and a wart behind. It lives in June and 

 again late in the Autumn on poplar, willow, 

 and birch. The pupa is chestnut -brown, 

 barrel-shaped, and enclosed in a slight cocoon 

 in the ground. 



N. dictaeoides, Esp. The Lesser Swallow 

 Prominent is very like the last species in 

 colour and markings. Of the white nervures 

 which cross the black longitudinal stripe to- 

 wards the inner margin of the fore wings, 

 nervure ib. is expanded into a white triangular 

 spot. The black transverse streak above the 

 seal}' projection on the inner margin of the 

 fore wings, as well as the white line which 

 crosses the dark spot at the anal angle of 

 the hind wings, is indistinct. The moth 

 appears in May and June, and is less common 

 than tvemula. The larva is smooth shining 

 green, with a yellow lateral line and a red 

 spine on the last segment. It lives from July 

 till late in the Autumn on birch.
