follows: — "The insect which causes the uianna to be formed on the white gum trees, 

 by perforating the delicate young branches, for the purpose of feeding on the sap." 



Mr. Bond exhibited a remarkable instance of arrested development in the left fore 

 wing of a specimen of Colias Hyale; also a female specimen of Lycaena Adonis, in 

 which some of the eye-like markings on the under surface were on the left side 

 (i.e. right of the under surface) wholly wanting. 



Mr. Haward exhibited a miscellaneous collection of Coleoptera, collected by him- 

 self three or four years ago in Central Europe, principally in Southern France and 

 Germany, and in Switzerland, and North Italy. 



Mr. Stainton exhibited two bramble leaves, inside each of which was visible 

 the cast-off skin of a larva of Nepticula aurella, and read the following note by 

 Mr. C. Healy :— 



Observations on the Moulting of the Larva of Nepticula aurella. 

 " On the 18th of January, 1863, I collected several bramble leaves containing 

 young larvse ; in the afternoon of the same day I observed one larva resting in the 

 centre of its mine in an apparently sickly state. On the following morning the old 

 skin had split at the first segment, and the darkish blotch at the back of the head had 

 receded to the second segment. On the 20ih the old skin had shrunk to the fifth 

 segment, and at this date ihe whole of the first four segments had quite a transparent 

 appearance, being devoid of all markings whatever, and contrasting strangely with the 

 remainder of llie laiva's body ; the larva lay quite motionless in its mine. On the 2Ist 

 the mouth had regained its former brownish colour, and the larva now moved its head 

 about in a languid manner in search of food, of wliich it partook sparingly. On the 

 22nd the darkish blotch had reappeared on the back of the larva's head ; the old skin 

 in the meanwhile having shrunk still lower down, the anterior portion of the body had 

 now become much stouter and had a more healthy and fresher appearance ; the larva 

 now commenced feeding with great eagerness: at this period the dorsal vessel, which 

 had lately become more distinct at the fore and after part of the larva's body, was 

 quite hidden in the centre. On the 23rd the whole of the dorsal vessel was distinctly 

 visible, the anterior portion being of a much brighter green than ihe posterior." 



Professor Westwood exhibited drawings sent from Australia by Dr. Howitt, of two 

 species of Lucanidse; one was the species recently described by the Professor as Rys- 

 sonotus? jugularis; the other, the original of which was found in Gipps' Land, was 

 probably the male of Dorcus Pelorides, of which the female was in the British 

 Museum. 



Professor Westwood also called attention to a paper in the 'Tijdschrift voor 

 Entomologie,' by Prof. Van der Hoeven, upon Periphyllus Testudo, a Hemipterous 

 insect which always remained in an apterous state ; and to a paper on the Insects of 

 Ceylon, by M. Motschulsky, in the Bull, de la Soc. Imp. des Nat. de Moscou. 



Mr. Waierhonse exhibited British specimens of the following species of Homalota 

 which are not included in his ' Catalogue:' — 



1. Homalota velox, Kraatz. One specimen taken by Mr. Waterhouse at Brocken- 

 hurst, in the New Forest, and a specimen taken by Mr. Hislop in Scotland.
