of Nemeobius lucina in its first stage, showing the conjoined dorsal 

 turbercles, each carrying two hairs, which are remarliable in being divided 

 into two branches. For comparison he also showed, by means of the 

 lantern, drawings of the young larva of Papilio ajax, after Scudder, and 

 of a portion of a segment of Smer'mtlms jjojmli, as the only instances known 

 to him of similar dichotomous hairs in lepidopterous larvae. Mr. E. B. 

 Poulton pointed out that he had described the forked hairs of Smerinthus 

 in the Entomological Society's ' Transactions ' for 1885, and that such 

 hairs were even better developed in the genus Hemaris originally described, 

 as he believed, by Curtis. Mr. Poulton also said that he had noticed 

 similar forked hairs covering the newly-hatched larvae of Geometra papilio- 

 naria. Mr. Poulton exhibited, and made remarks on, a number of cocoons 

 of Halias prasinana, in order to show the changes of colour produced in 

 them by their surroundings ; he also exhibited the coloured backgrounds 

 employed by him in his recent experiments on the colours of larvae and 

 pupae, and illustrated his remarks by numerous drawings on the blackboard. 

 Dr. Chapman read a paper — which was illustrated by the oxy-hydrogen 

 lantern — entitled " On some neglected Points in the Structure of the Pupa 

 of Heterocerous Lepidoptera and their Probable Value in Classification." 

 A discussion ensued, in which Mr. Elwes, Mr. Poulton, Mr. Champion, and 

 Mr, Merrifield took part. Dr. F. A. Dixey communicated a paper entitled 

 " On the Phylogeneiic Significance of the Variations produced by Differ- 

 ences of Temperature on Vanessa atalanta." The President, Mr. Merrifield, 

 Mr. Poulton, Dr, Chapman, and Mr. Tutt, took part in the discussion which 

 ensued. — H. Goss, Hon. Sec. 



March 8th.— Renrj John Elwes, Esq., F.L.S., F.Z.S., President, in 

 the chair. Mr. Frank. E. Beddard, M.A., F.R.S., of the Zoological 

 Gardens, Regent's Park, N.W. ; Monsieur Edouard Brabant, of Chateau 

 de Moreuchies, Cambrai, France ; Mr. Frank Bromilow, of Avalon, St. 

 Maurice, Nice, France ; Mr. Henry Powys Greenwood, F.L.S., of Harn- 

 ham Cliff, near Salisbury; Mr. Frederick Michael Halford, of 6, Pembridge 

 Place, W.; Lieutenant-Colonel Leonard Howard L. Irlty, F.L.S., of 41, 

 Cornwall Terrace, Regent's Park, N.W. ; Mr. Bertram S. Ogle, of Steeple 

 Acton, Oxfordshire; Herr Wilhelm Paulcke, of o'6, Langstrasse, Baden- 

 Baden, Germany; Mr. Louis B. Prout, of 12, Greenwood Road, Dalston, 

 N.E.; and Captain Savile G. Reid, late R.E., of Foyle House, Alton, 

 Hants, were elected Fellows of the Society ; and Herr Pastor Wallengren, 

 of Farhult bei Hoganas, Sweden, and Herr Hofrath Dr. Carl Brunner von 

 Wattenwyl, of Vienna, were elected Honorary Fellows of the Society to fill 

 the vacancies in the list of Honorary Fellows caused by the deaths of Prof. 

 Hermann Carl Conrad Burmeister and Dr. Carl August Dohrn. Dr. D. 

 Sharp exhibited a species of Enoplotrupes from Siam, which was believed 

 to be new, and which he thought Mr. Lewis intended to describe under the 

 name of E. principalis. This insect had great power of making a noise, 

 and the female seemed in this respect to surpass the male. Mr. W. F. H. 

 Blandford said he wished to supplement the remarks which he made at the 

 meeting of the Society on the 8th of February last on the larva of Rhyn- 

 chophorus. He stated that he had since found that only the first seven 

 pairs of abdominal stigmata were rudimentary. The posterior pair were 

 well developed and displaced on to the dorsum of their segment, which was 

 thickly chitinised, and bore a deep depression, on the margins of which the 

 spiracles were situated. He suggested that the absence of lateral spiracles
