Mr. M‘Lachlan exhibited ten of the thirteen species of Lepidoptera 
collected by Captain Feilden and Mr. Hart in Grinnell Land, between the 
parallels of 78° and 83°N. lat., during the recent Arctic Expedition. They 
consisted of Colias Hecla, Lef., var.; Argynnis polaris, Bdy.; A. Chariclea, 
Schnd., many yars.; Chrysophanus phleas, Linn., var.; Lycena Aquilo, 
Bdy.; Dasychira Grenlandica, Wocke; Mamestra? n. sp.; Plusia parilis, 
Hiibn.; Psycophora Sabini, Curt.; and Scoparia, n. sp. He entered into 
some details respecting the insects generally of this high northern region 
and their habits, in anticipation of his extended Report to be read at the 
next meeting of the Linnean Society. 
The Rey. A. EK. Eaton remarked, with regard to Arctic insects, that he 
was disposed to consider that their transformations may sometimes be 
protracted through two or more summers. He adduced some apparently 
analogous phases in respect of plant life in Spitzbergen, where he had 
noticed, in June, plants seemingly upon the point of flowering, which had 
evidently remained in that state under the snow since the previous autumn. 
He said that in the islands referred to insects are not altogether indifferent 
to the approach of midnight, although the diurnal variation of light does not, 
in July, equal in intensity the difference between rural sunshine in this 
country and the light which passes for daylight in London when the sky is 
slightly overcast. He mentioned, in conclusion, that no Bombus has been 
hitherto found in Spitzbergen, and that Pedicularis hirsuta appeared to be 
unvisited by insects in that archipelago. 
In reply to a question from the President as to the habits of the Arctic 
Culex, the Rev. A. E. Eaton remarked that when in Spitzbergen he had 
suffered much from the attacks of this insect, which had the habits of a 
true mosquito. 
Mr. Meldola exhibited a five-winged specimen of Gonepteryx rhamni, 
caught near Brandon, Norfolk, in August, 1873, by Mr. John Woodgate. 
He also exhibited a gynandromorphic specimen of Pieris brassice@, taken 
near Thame, Oxfordshire, by Mr. J. B. Watson, in August, 1877. In this 
last specimen the right fore and hind wings were female and the left male; 
the right antenna was also longer than the left. 
Mr. H. Goss exhibited an hermaphrodite specimen of Gonepterya rhamni, 
caught in Abbot's Wood, Sussex. He stated that he believed the specimen 
to be what Ochsenheimer called a “ perfect hermaphrodite,” the whole of 
the right side, both in characters and organs, being female, and the whole 
of the left side male. Mr. Goss remarked that from the recorded instances 
of hermaphroditism among the Lepidoptera it appeared that it was more
