the apex of both fore-wings, quite white in colour. A specimen of 
Leucania pattens, exhibiting aberrant neuration. A specimen of 
Mamestra brassicae, having a ruddy tinge all over the fore-wings. Two 
female Agrotis puta, strongly suffused with red. A specimen of 
Tnjpliaena pronuba, with dark longitudinal lines on the fore-wings. 
Mr. Tutt remarked, with regard to the red form of A. puta, that this 
was Hiibner’s type. He had captured a male, richly tinted, at 
Deal, and recorded the same in Brit. Noctuae and their Varieties. 
Captures in Suffolk.— Mr. Bloomfield exhibited Catocala sponsa, 
Dianthoecia cucubali, etc., from Bures, Suffolk. Food-plant of Papilio 
machaon. — Mr. Tutt, referring to a remark made concerning the food- 
plant of this species in the Alps, said that it was undoubtedly Daucus 
carota and the allied umbellifers, which were exceedingly abundant 
at pretty high elevations. It occurred up to 8,000 ft., and he 
referred to a fact, first noticed by Mr. Lemann, that the species 
had, in the high Alps, a habit of flying about the grassy knolls 
which surmounted many mountains at a considerable elevation. 
Spread of species. —Mr. Frost drew attention to the fact that he often 
caught an odd specimen of TJnjas paphia in localities where it did not 
usually occur, and often somewhat later than is usual in the New 
Forest, and other localities where it was regularly abundant. He 
asked whether the members thought it was due to an attempt to 
spread its area. Mr. Tutt said that he had no doubt there was a 
tendency in many insects to do this. He had observed both sexes of 
Aporia crataeyi at Lautaret, above the tree limit, and where there was 
no trace of any of their food-plants, unless “ Cotoneaster,” a food-plant 
mentioned by Frey and which he did not know, occurred there. He 
believed the specimens observed at high altitudes, were all stragglers 
from the lower valleys. Egg of Pamphila comma.— Mr. Tutt exhibited 
eggs of I’, comma which had been obtained by Mr. Hamm. He stated 
that the egg had been described by Buckler, but that a description of 
the larva was a great desideratum. There was considerable uncertainty 
even as to the food-plant. He also referred to the fact that this 
species hybernated in the egg stage, and that a description of the egg 
of Tlujmelicus actaeon was still wanted. Alpine Aglais urticjE.— Mr. 
Tutt also exhibited specimens of A. urticae, the larvie of which had 
been obtained at Lautaret, where they were abundant, on a patch of 
stinging nettles, near the Hospice. The larvie pupated in a large 
chip box. A very large percentage, however, was infested with 
dipterous parasites — of two species. The imagines emerged on August 
30th, after a journey from Lautaret to London via Grenoble. He 
called attention to the fact that the usual deep red hue of the Alpine 
specimens was wanting, and that they were very little different on their 
upper sides from those of southern England, but on the undersides 
there was a considerable contrast between the pale and dark areas of 
the fore-wings, the central transverse band was very marked, and the 
blue spots parallel to the outer margin of the hind-wings were very 
strongly developed. He also showed the pupa-cases, and drew atten¬ 
tion to the mode of dehiscence. 
October 6th, 1896. — Sirex juvencus at Eltiiam. — Mr. J. A. Clark 
exhibited a specimen of S. juvencus, captured the preceding day
