THE FAUNA OF SCOTLAND. 31 



Legs yellowish- green, claws brown. The body dark-grayish or whitish- 

 green, with a faint white line along the sides, and marked also with some 

 darker-green spots. 



Possil Marsh. 



Eannoch, Strath-Carron, above Ardgay. 



Specimens from Possil are rather dark coloured ; the abdomen is quite 

 black, except at the extreme tip; the mesonotum bears three black marks. 

 The mesonotum is quite black. 



. 7. N. APicALis, Htg. 



Eare. Imago in May. Larva unknown. 



Cadder, Bishopton. 



A black species, with more or less pale legs, mouth, anus, and alar 

 nervures; seems to be the apicalis of Hartig, but there is a possibility that 

 Hartig's insect may have been a black variety of fallax ( = humeralis, 

 Zett.), which our insect is certainly not. 



8. N. CAPREAE, P%. 



= kirbyi, Dbm., Thorns. . 



Abundant. Imago in May and June, and again in July. Larva in 

 July and the autumn months. Food plants — carices and grasses. 



The larva has the head of the size of the 2d segment; the ground colour 

 is yellowish-green or gray; the vertex covered with small brown dots; eye- 

 spots black, and above them is a small dark stripe, in the centre of the 

 face a clear light green triangular space; the mouth brown. The body is 

 cylindrical, rather thin, 'narrowed behind; the skin beset with small dots, 

 each ending in a hair; the colour is dark-green to the spiracles, where 

 there is a narrow white line, below which the colour assumes a lighter tint. 

 The dorsal vessel is observed as a thin black line, bordered on each side 

 by a white one of the same breadth. These are not visible on the 2d and 

 last segments. The junction of the segments is marked by a white line. 

 Over the legs the skin is raised in folds, like blisters; when full-fed the 

 body becomes entirely green. A rather rare variety of the larva is of a 

 crimson-red colour, with the usual white lines.
