HIBERNATION OF THE LARVA OF LYCANA 
ARGIADES. 
By F. W. Frouawk, M.B.O.U., F.E.S. 
Durine July, 1913, I obtained a large number of eggs from 
L. argiades females which were captured at Rennes. Also many 
eggs of this species from females captured in Hungary; these 
were laid during the first half of August. 
The larve from both the French and Hungarian parents 
entered into hibernation about the end of September. 
After the first moult the larve became striped with brown, 
the ground-colour being pale yellowish; the medio-dorsal and 
oblique side stripes brown, and the lateral stripe rust-coloured. 
After the second moult the ground-colour is pale ochreous- 
green, the medio-dorsal and lateral stripes are rich purple- 
brown, and the oblique stripes are paler. The colouring remains 
similar until after the fourth and last moult, and when fully 
grown the ground-colour is a very pale pinkish-ochreous; the 
medio-dorsal stripe is deep purplish-brown, the lateral stripe 
light chocolate-brown, and the oblique side stripes light rust- 
colour. ‘They remain so coloured during hibernation. 
As the larve develop, all the green colouring disappears ; 
and during the last stage no green form existed in any of the 
larvee when they entered into hibernation. Some of the larve 
hibernated in the dead rolled-up leaves of Lotus corniculatus, and 
some low down on the stems of the plant. They spin a fine 
layer of silk to rest upon during hibernation. 
No brown form occurred in the last stage of the larve reared 
from eggs laid July 24th, 1904, by a female argiades captured 
in the South of France. Although when young (after the first 
moult) two distinct forms of the larve appeared, one being 
striped with brown, the other entirely green, with very slightly 
darker green markings. After each subsequent moult the 
striped forms gradually lost the markings, and after the last 
moult all were entirely green, excepting a few which had the 
lateral ridge tinged below with pinkish-brown. 
The larve pupated at the end of August, and the imagines 
emerged between September 6th and 18th inclusive. 
The complete life-history of this species I published in the 
‘Entomologist,’ vol. xxxvii. pp. 245-9. 
NOTES AND OBSERVATIONS. 
PANORPA coGNATA (NeuRopTERA).— Mr. H. Scott (University 
Museum of Zoology, Cambridge) has been good enough to send me a 
few new records of the scarce British scorpion-fly Panorpa cognata.
