Mr. Stainton exhibited Cosmopteryx Lieniijiella, bred from English larvae. 
With reference to a query as to whether Argynnis Niohe and Adippe mighi 
be one species, with dimorphic larva, Mr. Stainton nientioned the dimorphic 
of that of Acheronf.ia Atropos, though not as tending to prove the identity d 
two species of Argynnis. Mr. Butler was still inclined to believe in the poa 
identity of the two species, though confessedly he knew nothing of the larvae, 
had seen the two forms dallying one with the other in the Alps. 
Mr. Kirby communicated "Notes on Butterflies described by Linnaeus." 
4th April, 1870.— A. R. Wallace, Esq., F.Z.S., President, in the Chair. 
H. \Y. Freeland, Esq., of the Athenaeum Club, was elected a Member. 
Mr. A. P. Falconer sent for exhibition a mole-cricket, found in a boat beti 
Philoe and Alexandria. This was identified as most probably Gryllotalpa Coph 
De Haan, according to Scndder. 
Mr. Jenner Weir (for Mr. Vogan, present as a visitor) called attention to 
enormous harm done in granaries by weevils. Out of 74 tons of wheat y 
housed by Mr. Vogan, 10 cwt. of weevils had been sifted at one time ; in ] 
145 tons of maize were stored, and in August, 18^9, 6 cwt. of weevils were £ 
rated therefrom, and in December, 1869, 29 cwt. more. In both instances 
depredator was SitopMlus oryzce. 
Mr. Vogan asked for information respecting the earlier stages of the in 
and if it were probable that it would attack standing or newly-ripe corn. It 
the general opinion of the meeting that it only infested dry cereals, in whii 
continued to breed 'in and in.' Mr. McLachlan referred to the fact of ship-bii 
being extensively attacked by SitopMlus ; and in this case the only remedy ccmsi 
in re-baking. It was urged that, in the case of corn, this process would utt 
destroy its value. 
Mr. Vaughan exhibited a box of bred examples of Dianthoecia carpnphaga 1 
Croydon, the specimens shewing very considerable variation in colour. 
Mr. Miilier remarked that he had received a letter from Mr. Bassett 
Waterbury, U. S. A,, confirming his observations as to the odour emitted 
Cynipidcv. 
Mr. Smith exhibited Masoris vespoides of Cressou, and Pterochilus 5-fasci 
of Say, both from the Rocky Mountains. 
Mr. Weir exhibited a collection of Argynnis Niobe and Adippe, typical fc 
and varieties, with a view of proving the perfect specific right of the two spei 
as opposed to the views held by Mr. Butler. 
Mr. Dunning read an extract from the Journal of the Society of Arts, respec 
the spectrum produced by the fire-fly of New Hampshire. This was perfe 
continuous, without traces of lighter or darker hnes, extending from a little al 
Frauenhofer's line C in the scarlet to about F in the blue, gi-adually fading at 
extremities. 
Mr. Crotch communicated notes on British species of Dasytidce, and exhib 
British examples of D. plumieus (Miilier), D. ceratxi,s (Stephens), and Dolichos 
profensa (Gene).
