flight, or the smallest splash of colour in common, had often caused 

 him to take the insect for something that is otherwise utterly unlike 

 it, and such a hesitation would usually cost a bird the insect. He 

 also exhibited, on behalf of Dr. E. C. L. Perkins a male of Prosopis 

 nubilosa, Ckll. (Prosopidas), and of a species of Halictus (Andrenidie) 

 captured by him in the Cairns district of North Queensland (July, 

 1904). Dr. Perkins had pointed out to the speaker the extremely 

 interesting manner in which the resemblance between these species 

 had been brought about, the hard glistening yellow mark on the black 

 scutellum and post-scutellum of the Prosopis and that on its lateral 

 prothoracic tubercles being mimicked by a yellow pubescence occupy- 

 ing the same positions in the Halictus. This had been previously 

 noticed by Meyrick, probably in the female of the same species. — 

 The Eev. G. Wheeler, two specimens of a new Argynnis, discovered 

 in June last by Mr. Harold Powell, F.E.S., at Lambessa in Algeria. 

 Mons. Oberthur named it auresiana. — Dr. W. A. Lamborn, some 

 cocoons formed by wild larvae of Norasuma kolga under natural 

 conditions, under leaves. They gave a good idea as to the mimicry 

 of Braconid cocoons by the formation of little bosses of yellow silk. 

 — Mr. Donisthorpe: (1) A small incipient colony of Camponotus 

 ligniperdus taken at Yvorne, Switzerland. (2) Specimens of a Procto- 

 trupid new to science, Loxotropa donisthorpei, Kieffer, taken in a 

 nest of Lasius flavus at Blackgang Chine, Isle of Wight, September 

 9th, 1912. (3) A specimen of Camponotus abdominalis var. atriccps, 

 Smdt., an American species which probably had come from the hotel 

 at Weybridge, as he was told of the capture of other specimens 

 there on his next visit. — Mr. L. W. Newman : (1) A long and varied 

 series of the hybrid Smerinthus ocellatus $ x Amorpha populi 2 , 

 bred September, 1912, out of doors, from pairing obtained June, 1912, 

 the lame pupating in June and early August. (2) Living specimens 

 of the hybrid Zonosoma pendularia $ x omicronaria 5 (annulata). 

 The specimens showed characters of both species well, and vary 

 somewhat in the quantity of pink coloration. (3) A living male 

 specimen of Metrocampa margaritaria, taken at rest in Bexley 

 Woods, October 14th, 1912, which points to a second emergence of 

 this species. (4) A male specimen of S. ocellatus bred out of doors 

 on September 14th, from larvae which pupated in June, 1912. — Mr. 

 K. G. Blair, larvae of two allied species of Malacoderm from Borneo, 

 brought by Mr. J. C. Moulton. The species to which these larvaa 

 belong are not yet known, although probably belonging to the family 

 Lycidae. — Mr. H. M. Edelsten, specimens of Nonagria dissoluta and 

 var. arundmeta from East Kent, bred during August, 1912, 75 per 

 cent, from this locality being dissoluta. — The following papers were 

 read : — " Notes sur quelqes especes des Lucanides dans les Collec- 

 tions du British Museum et de l'Universite de Oxford," par M. 

 Henri Boileau, E.E.S. " Synaposematic Resemblance between 

 Acrseine Larva?," by G. D. H. Carpenter, B.A., M.B., F.E.S.—
