aca 
appeared to be the only other person who had found the winged 
forms in this country. The 3¢ and 29 are much larger than 
the % %, the latter being our smallest British ant. It is very 
rare and local in Britain, having only occurred at Deal, 
Southend, the Isle of Wight, and Portland. 
ABERRATION OF PyRAMEIS INDICA——Mr. H. EH. GREEN 
exhibited an aberrant example of Pyrameis (Vanessa) indica, 
Herbst, from Ceylon. He remarked that the aberration was 
apparently caused by a sudden change of temperature at the 
critical period of pupation. A few full-fed larvae had been 
sent from Nuera Eliya (alt. 6,500 ft.) to Peradeniya (alt. 
1,500 ft.), where they immediately pupated ; of three specimens 
that emerged successfully, one was normal, while the other two 
had assumed the coloration of the example now exhibited. 
Though P. indica occurs in the plains, on the Indian continent, 
it is found only in the hills, in Ceylon. Its food-plant—the 
giant Nilgiri nettle—is more or less confined to the mountain 
region of Ceylon, though Trimen has recorded its occurrence 
at considerably lower elevations. This particular aberration 
of the butterfly has been figured in a recent number of “ Spolia 
Zeylanica.”’ 
CoRYDALIS ORIENTALIS, McLacu.—Comm. J. J. WALKER 
exhibited a 9 specimen of the gigantic Neuropteron, Corydalis 
orventalis, McLach., taken by a native collector at Chuchow, 
Chekiang Province, S.E. China, May 1913, and forwarded to 
the exhibitor by C. T. Bowring, Esq., F.E.8., of Wenchow. 
The species was described in Trans. Ent. Soc., 1899, pp. 281-3, 
plate ix, from a single mutilated specimen taken at Chia-tung- 
fu, W. China, by one of the late Mr. Leech’s collectors. Species 
of Corydalis are numerous in North America, but only three 
(C. asiatica, Wood-Mason, from the Naga Hills, C. orientalis, 
McLach., and a doubtful species from Assam) have been 
recorded from the Old World. 
ABERRANT AND Hysrip HeTerocera.—Mr. L. W. New- 
MAN exhibited the following Heterocera :— 
(1) Calymnia (Cosmia) trapezina. A melanic 9, the whole of 
the fore-wings very dark brown, with white transverse lines; 
a worn specimen taken at sugar in Bexley Woods. 
(2) Zonosoma (Ephyra) annulata and pendularia; a long
