42 THE ENTOMOLOGIST. 



on the Lancashire coast, and discussed by Mr. South in the ' Ento- 

 mologist,' 1889, p. 271, where he expresses the opinion that it may 

 be a form of Luperina testacea intermediate between L. gueneei and 

 L. nickerlii, and later on (oj). cit., 1909). The exhibit also included 

 three specimens of what are taken to 136 authentic L. nickerlii, the 

 first two obtained from a Vienna collection, said to be Nickerl's own 

 collecting, and over fifty years old; the third belonging to Mr. 

 South, and labelled " Bohemia ' ; a series of undoubted L. testacea, 

 mostly labelled from about the same Lancashire district, with four 

 specimens of the doubtful insects, and several specimens of undoubted 

 L. testacea of the palest form, taken mostly at Rainham, and named, 

 more for convenience than from conviction, L. gueneei. Mr. Burrows 

 pointed out that the form of the fore wings in the Lancashire insect 

 is much narrow^er than in either L. testacea or (reputed) L. nickerlii, 

 and said that with respect to the possible connection of these Lan- 

 cashire specimens with L. gueneei, he had consulted what he believed 

 to be Henry Doubleday's original description in the ' Entomologists' 

 Annual,' for 1864, p. 123, but that he was not acquainted with the 

 " three round white dots on the costa near the apex," in our common 

 species, and did not see them in the (reputed) L. nickerlii. — In the 

 absence of Mr. J. W. Tutt, who was indisposed, Dr. T. A. Chapman 

 opened a disussion on the affinities of Agriades thetis (bellargus) and 

 A. coridon, and exhibited a number of photographs upon the screen 

 to illustrate his views, being details of species included in the 

 Plebiid group. These included slides of the ova of thetis and coridon 

 by Mr. F. Noad Clark and Mr. A. E. Tonge, and of the first instar of 

 larvffi of P. argus, L., P. argyrognomon, A. coridon, and A. thetis ; a 

 photograph of the larvse of A. thetis, by Mr. Hugh Main, showing 

 the " fan " structures remarkably well ; also many slides illustrating 

 the differences in the genital armature of the two species under 

 review, and their allies. — The Rev. G. Wheeler, Mr. G. Bethune- 

 Baker, and other Fellows continued the discussion, which was 

 eventually adjourned until the February meeting. — Mr. C. P. Pickett, 

 Mr. A. E. Gibbs, Mr. J. W. Tutt, and Dr. Chapman, also submitted 

 series of A. coridon and A. thetis with varietal forms and aberrations. 

 — Mr. T. Bainbrigge Fletcher, R.N., communicated a paper " On the 

 genus Deuterocoims, Zeller." — Mr. H. St. J. Donisthorpe, F.Z.S., 

 communicated a paper on " Some Experiments with Ants' Nests." — 

 H. Rowland-Beown, M.A., Hon. Secretary.

 Society.— Oc^. I^th, 1909.— The President in the chair.— Mr. Percy 

 Bright, of Bournemouth, and Mr. G. Bowen, B.A., of Kingston-on- 

 Thames, were elected members. — Mr. Tonge exhibited living larvae of 

 Pharetra rumicis from Hatfield, feeding on sallow. — Mr. South, a series 

 of Hylophila prasinana, bred, from Scarborough, in some of which a 

 brilliant red markings had developed. — Mr. West (Greenwich), 

 specimens of the Homopteron, Idiocerus aurentulus, from Blackheath. 

 It had only once before been taken in Britain. — Mr. Newman, series 

 of Agrotis cinerea from Kent, Lewes, and Brighton ; the Sussex races 

 were much the smaller. - Mr. R. Adkin, a female of Ocneria dispar 

 taken at rest on an elm-trunk at Eastbourne, and read notes on the
