BEITISH MOTHS. 



83. The Black Arches (Male) (Liparis monach(i). 



lines crowded together ; at a short distance 

 follows the fifth line, and on the hind margin 

 of the wing are nine black spots ; hind wings 

 of the female smoke-coloured, with a pale 

 marginal band, in which are six or seven dark 

 spots ; head white, palpi, antennse, and eyes 

 black ; the antennae of the male have white 

 shafts ; thorax with a black mark in front, 

 close behind the head, and three or four black 

 spots in the middle ; body rosy-red with a row 

 of black dots down the middle, and a row on 

 each side ; legs black and white in the male 

 black in the female. The caterpillar is grey 

 and hairy, with a darker stripe down the back ; 

 the second segment has two bluish tubercles 

 on the back ; the ninth, tenth, and eleventh 

 segments have a reddish tubercle on the 

 back. It feeds on oak, birch, &c. ; spins a 

 slight cocoon in July, in the crevices of the 

 bark ; and changes to a blackish shining chry- 

 salis, which is ornamented with brushes of 

 dark hair on every segment. The Moth ap- 

 pears in July and August, and is not common. 

 (The scientific name is Liparis monacha.) 



84. The Tale Tussock (Orgyix p't'libitiuln}. 



<U. TIIK PALE TUSSOCK. Fore wings of 

 th- inal u givy. with a broad central smoke- 

 coloured transverse bar, more or less distinct ; 

 this bar includes several darker waved lines ; 



The Black Arches (Female). 



the fringe on the hind margin has seven or 

 eight dark spots ; the fore wings of the female 

 are pale-grey, without the central bar, but in- 

 stead of this they have two transverse, rather 

 waved, lines, one rather before the middle, and 

 the other rather beyond ; the fringe is spotted 

 as in the male ; hind wings in both male and 

 female nearly white, with a faint greyish cen- 

 tral transverse bar, which is most conspicuous 

 towards the anal angle : head, thorax, and 

 body grey ; fore legs of the male very hairy. 

 The caterpillar is of a delicate green colour, 

 with a band of the most intense velvety black 

 between the fifth and sixth segments, another 

 between the sixth and seventh, and a third 

 between the seventh and eighth ; all these 

 four segments have a thick tuft of yellow hair, 

 like a brush, on the back ; the twelfth segment 

 has a longer and more slender tuft, directed 

 backward ; it feeds on oak, lime, hazel, edible 

 chestnut, and many other trees. I have had a 

 number of these caterpillars this year, and 

 have observed that before they changed their 

 skins, they spin a little silken house, bending 

 a leaf over their backs. They feed through 

 June, July, and August, spin a slight web 

 among the leaves, and turn to a hairy chrysalis, 

 which turns to a Moth the following May. The 

 beautiful caterpillar is common everywhere : it 

 is called the " Hop-dog " ; the Moth not so 

 often seen. (The scientific name is Orgyia 

 pudibunda.) 



85. THE DARK TUSSOCK. Fore wings 

 smoky-grey, with three transverse dark waved 

 markings ; the first of these is near the base, 

 the other two are near together, and beyond 

 the middle of the wing ; all are accompanied 

 by orange-coloured sprinkled dots; and there 

 is n dark dotted line along the hind margin,
