butterfly. The species flew rapidly with a zigzag flight by 
day in the bright sunshine from about ga.m. until 4 p.m., on 
the sides of the mountains, hovering over the bushes, and 
frequently settling on the flowers and grass. An allied 
species had been captured in the Cogne valley in August, 
1894, where it frequented cultivated meadows just above the 
village of Cogne. The notion of Kirby and Spence that 
the species of Ascalaphus fly ‘‘among fir trees”’ is not at all 
correct for the habit of these two species. 
Mr. Adkin exhibited series of Czdaria suffumata bred from 
ova obtained from parents taken at Loch Laggan, together 
with examples from Forres, Dover, and Boxhill for com- 
parison. The Laggan specimens were all darker than the 
usual southern type, and included numerous examples of 
var. piceata, and of a form intermediate between that variety 
and the type. 
Mr. Tunaley exhibited a specimen of Retinia resinella 
which had just emerged from a resinous nodule of pine sent 
him from Aviemore. Heshowed sections of several nodules, 
and said that the females had emerged before the males, 
which was a somewhat unusual circumstance in the Lepi- 
doptera. He had noticed that the head of the pupa was 
just near the surface of the nodule, and only separated from 
the air by a thin layer, while around the pupa the nodule 
was much harder. The channels in the nodule where the 
larva had wandered were filled up with further resinous 
matter, and no doubt the hard cocoon prevented this new 
exudation from unduly pressing on the pupa. The cocoon 
was lined with a soft but tough silk. The pupa case thrust 
itself out mechanically to just beyond the wing-cases, and 
quite go per cent. of the cases were finally dragged away 
during the struggles of the imago in emerging. In answer 
to Mr. Adkin he stated that he could not succeed in ascer- 
taining how the pupa successfully broke the thin resinous 
wall of the nodule. (See also “ Proc.,” 1888-9, p. 160, and 
plo i:) 
Dr. Chapman exhibited among other insects a living 
specimen of Charaxes jasius which had emerged from pupa, 
the larva having been taken at Cannes. 
Mr. Step communicated a short paper entitled ‘‘ Note on 
a Variety of Portunus marmoreus, Leach” (ante, p. 38), and 
also a coloured drawing of the variety with the type form 
for comparison. 
Mr. Tutt read a paper entitled ‘‘ Spring Butterflies on the 
Riviera’ (ante, p. 41).
