Undor those circumstances a mere trick of flight or the smallest splash of colovir 

 in common had often caused him to take the insect for something that is other- 

 wise utterly unlike it, and such a hesitation would usually cost a bird the insect. 

 He further drew attention to a letter he had received nearly two years ago from 

 Mr. G. F. Leigh, describing the breeding of E. cZriyoj^e and di-awing the inference 

 tliat the species was distinct from Marhas. Professor Poulton, on behalf 

 of Dr. R. C. L. Perkins, a male of Prosopis nuhilosa, Ckll. (Prosopidse), and 

 of a species of Halictus {Andrenidx), 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 insects 

 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 occupying the same positions in the 

 Halictus. This had previously been noted by Meyrick, probably in the 9 of the 

 same species. The Rev. G. Wheeler, two specimens of a new Argynnis, discovered 

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

 Mons. Oberthiir named it auresiaria. ,;Dr W. A. Lamborn, cocoons formed by 

 wild larvffi of Norasuma kolga vuider leaves. They gave a better idea than those 

 formed in captivity 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, October 8th, 1912. 

 (2) Specimens of a Proctotrupid 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 abd.ominalis var. atriceps, Snidt., an 

 American species, captured alive in his i-oom on his return from Weybridge, 

 September 6th, 1912, probably coming from the hotel at Weybridge, as he was 

 told of the capture of other specimens there on his next visit. Commander 

 Walker observed that one of the Aiistralian species of Camponotus occurred 

 constantly in houses, and was familiarly known as the " sugar ant." 

 Mr. L. W. Newman, (1) a long and varied series of the Hybrid Smerinthus 

 ocellatus $ x Amorpha populi ^ , bred September, 1912, out-of-doors, from 

 pairing obtained June, 1912, the larvae pupating in July and early August. 

 (2) Living specimens of the hybrid Zonosoma pendularia J x oinicronaria 9 

 (annulata) . The specimens showed characters of both species well, and vary 

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

 Metrocampa mar garit aria, taken at rest in Bexley Woods, October 1-lth, 1912, 

 wliich points to a second emergence of this species. (4) A 9 specimen of 

 S. ocellatus bred out-of-doors, on September 14th, from larva whicli pupated in 

 June, 1912. Mr. K. G. Blair, larvie of two allied species of Malacoderm Coleoptera 

 from Borneo, bronglit by Mr. J. C. Moulton. The species to which these larvae 

 belong ai-e not yet known, although probably belonging to the family Lycidx. 

 Mr. H. M. Edelsten, specimens of Nonagria dissoluta and var. arundineta from 

 East Kent, bred during Aiigust, 1912, 75 per cent, from this locality being 

 dissoluta.
