was very dark, while the third was.a bright green tint such as 
is usually produced on green, yellow or orange surfaces. The 
pupae were first observed at the beginning of November, 
1920, and had been taken on December 5. The locality was 
Southfield Road, Oxford. 
AESCHNA GRANDIS L., CAPTURED AND EATEN BY SPARROWS. 
—Prof. Poutron exhibited three wings of this large dragonfly 
left by a sparrow which had eaten the body. The bird was 
seen by Mr. H. Hounslow to fly into the back garden of Wyke- 
ham House, Oxford, carrying the insect, which it proceeded 
to eat upon the lawn. Earlier on the same day, July 22, 1920, 
he saw a sparrow in the front garden catch and fly off with a 
similar dragonfly. Prof. Poulton had not previously come 
across any record of the capture by birds of these large and 
powerful insects. 
Mr. G. T. BerounE-BakeEr brought for exhibition specimens 
of Lycaeninae from Provence (France) to show the large pro- 
portion of specimens of a more or less leaden-coloured blue 
taken in the summer of 1920. He said :— 
“| have examined the scales under the microscope, and in 
all cases I find them ill-developed. They are unusually thin 
and fine in texture, and in all cases they are curled—in some 
a single roll, but in others a curling up from each side to meet 
in the centre; the curling is from the apex of the scales, not 
from the base. | 
“ Polyommatus icarus from St. Martin Vésubie. Probably 
fifteen per cent. of the specimens I took were deficient in 
colour. 
** Polyommatus coridon.—I took no defective ones at St. 
Martin, but at la Sainte Baume several were taken: three are 
shown, but I took more. 
* Polyommatus hylas——Out of a dozen specimens taken by 
me at St. Martin only one has any approach to normal colour, 
and that is by no means really normal. 
“ Polyommatus escheri. Many deficient in colour were 
taken at both places. 
“ Polyommatus thetis (bellargus)—Several of this species 
deficient in colour occurred at both Digne and at Mont 
Ventoux (Vaucluse); both of these show signs of streakiness.
