The fact that the pupa is not attached or suspended in any way, either by , 
anal extremity or by a silken band round the middle like the other Tlwcla is „ 
remarkable. 
Probably its habit is to He near or on the ground among the thickest g 
and herbage. 
I leave the description of the larva? and green stumpy pupa to the pract^ 
pen of my friend, Mr. Buckler, to whom I had the pleasure of sending specim.

Notes on the ewrlier stages of Thecla ruhi.-The larva of this species had 1 
been a desideratum to me, even after all the other British species of the ger

Perhaps the reason was that myself and ftiends tried to take it from the hrav

shut up in a glass cylinder, with bramble buds and flowers, deposit their eggs 
them. Doubtless the larva has been found on bramble buds, as Albin's accoum 
it fully testifies, still I can now give two other food plants for it, which I can 
help fancying are more to its taste. 
On 25th June, 1868, Mr. W. H. Harwood, of Colchester, who had W 
acquaintance with the larva during the previous year, kindly sent me some 1' 
fuU-grown examples, beaten from broom. I lost not a moment in depicting thrf 
and no sooner were they done, than on the following day I received others fii 
Mr. C. G. Barrett, then at Haselmere, he having, quite by accident, discovered tb'

stages of growth. These from the Genista were not so brilliant in markings; 
those from broom, but otherwise identical; and from both sets of larvEe '

specimens. 
The full-grown larva is about |-inch in length, and gains nearly i-inch wl 
stretched out in walking; thick in proportion and somewhat onisciform in sha; 
flattened beneath, the head very small and retractile, the second and third si 
ments rounded above, the others to the tenth inclusive have a dorsal hollow -n^ 
an eminence on each side of it, which slopes thence to the lateral ridge ; the l' 
three segments are rather flattened above. 
The ground colour is a bright yellowish olive-green, the hollow of the backl! 
a darker, full green, and down its centre runs the pale olive-gi-een dorsal lil' 
which gradually widens and suddenly contracts on each segment throughout t 
course, and becomes darker on the last three segments, and bordered there h^i 
yellowish stripe on each side ; from each eminence on the other segments a thi: 
bright yellow streak slants backwards and downwards, bounded beneath by ■ 
equally thick streak of deep full green, most intense at its begmning on each s.« 
ment ; the lateral ridge has a stripe of yellow beginning at the third segmeut ai 
running continuously round the anal extremity ; parallel to this and above V 
spiracles is a faint indication of a stripe a little yellower than the ground coloi-f 
the head is pale brown with darker brown round the mouth ; the appearance \ 
the larva is velvety, caused by minute raised points bearing fine short bristles. '
