44 [February, 



The President anuounced that the Society would hold a Conversazione in 

 the month of May, 1910, and invited the co-operation and assistance of Fellows. 



Commander J. J. Walker exhibited 128 species of Coleoptera, belonging to 

 68 genera, which he had taken, by sweeping only, at Wytham Park, Berks., 

 between 12.30 and 3.30 p.m. on November oth, 1909 ; several local and uncommon 

 species were included among these, such as Homalota 'jmberula, Sharp, Anisotoma 

 cinnamomea, Panz. (both sexes), A. punctulata, GylL, Hydnohius 2}U7ictatissimus, 

 Steph., Cryptophayus pubesccns, Stvu-m, Phlosophilus edwardsi, Steph., Mantura 

 matthevjsi, Curt., Salpingus castancus, Panz., Apion Jilirostre, Kirby, &c., &c. 

 The Rev. C. R. N. Burrows, examples of an vmidentified species of Luparina, 

 captured during the past season on the Lancashire coast, an insect discussed by 

 Mr. South in the " Entomologist," 1889, p. 271, where he expresses the opinion 

 that it may be a form of Luperina testacea, intermediate between L. gueneei and 

 L. nickerlii, Mr. Tutt maintaining in his " Varieties of British Noctuas," vol. i, 

 p. 140, that it was a variety of Lioperina testacea ; the exhibit also included 

 three specimens of what are taken to be 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 " ; 

 also a series of undoubted L. testacea, mostly labelled from about the same 

 district, with fovu- specimens of the Lancashire insects, and several specimens 

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

 named, more for convenience than from conviction, L. gueneei. Mr. Burx"0ws 

 drew attention to the fact that the form of the fore-wings in the Lancashire 

 insect is much narrower than in either L. testacea or (reputed) L. nickerlii, and 

 said that with respect to the possible connection of these Lancashire specimens 

 with L. gueneei, he had consvilted what he believed to be Henry Doubleday's 

 original description in the " Entomologists' Anniial" for 186-1, p. 123 ; but tliat 

 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 discussion on the affinities of Agriades thetis (hellargus) and A. coridon, 

 and exhibited a number of photographs upon the screen to illustrate his views, 

 being details of species included in the Plebeiid group. These inchided slides 

 of the ova of thetis and coridon by Mr. F. Noad Clark and Mr. A. E. Tonge, and 

 of the first instar of the larvae of P. argus, L., P. argyrognomon, A. coridon, and 

 A. thetis ; a photograph of the larva of thetis by Mr. Hugh Main, shoAving 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 continvxed the 

 discussion, which was eventvially adjourned until the February meeting. 

 Mr. C. P. Pickett, Mr. A. E. Gibbs, Mr. J. W. Tutt, and Dr. Chapman also 

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

 Mr. T. Bainbrigge Fletcher communicated a paper "On the Genus Dcuterocojnis, 

 Zeller." Mr. H. St. J. Donisthorpe, on " Some Experiments with Ants' Nests." — 

 H. Rowland-Beown, Hon. Secretary.
