12 THE GENERA AND SPECIES OF BRITISH BUTTERFLIES. 
length in both sexes, though not fitted for walking. The Caterpillar is attenuated at each ex- 
tremity, with two short points at the tail. The pupa is short and thick, and furnished with 
several angular projections, especially two, much more conspicuous than the others, near the 
head. It is suspended only by the tail. 
Lasionmata Ageria (the Speckled Wood, No. 6) is one of the commonest of our brown 
Butterflies. It is subject to considerable variations in the intensity of its marks, but no very 
striking varieties oceur. The under side (No. 7) is very pleasingly varied in the tones of colour. 
The females are generally more brightly marked, and have the patches of light colour in the 
upper surface of the wings more extended than the male, and they are generally somewhat 
larger than the other sex. The Caterpillar (No. 8) feeds on Triticum repens, and other common 
grasses, from the blades of which the Chrysalis (No. 9) may often be found suspended. The 
perfect insect appears in April, June, and August, there being three or more broods in the year. 
It is common everywhere, generally frequenting shady lanes and hedgerows in preference to 
open meadows. 
Lasiemmata Megera (the Wall, No. 10) is the only other species of this genus. It is as 
common as the preceding. The male (No. 10) is always much smaller and more strongly marked 
than the female (No. 11). The under side of this species is very beautifully decorated with 
delicate rings, each of which enclose a series of smaller circlets, most perfectly and delicately 
pencilled, as shown at No. 12. The Caterpillar (No. 13) feeds upon various grasses, and is found 
in May and at the beginning of August, but must be sought at nights with a light, like most of 
those belonging to this group. The perfect insect appears in April and again in the Autumn. 
It frequents shady lanes and hedgerows, like L. <Ayeria.
