exhibitor; also Tetramoferia donistliorpei, Kieffer, n. sp., and T.femo- 

 ralis, Kieffer, n. sp., taken by himself with Tetramorium ccBspiUim, L., 

 at Whitsand Bay, Cornwall ; Paracletes civiiciformis, taken with 

 T. ccBspitum, L., at Barnes Head, Cornwall ; and Antennophorus 

 puhescens, Wasm., a species new to Britain, taken on Lasius flavus at 

 Whitsand Bay. — Mr. W. E. Sharp exhibited examples of the 

 following Coleoptera from the West of Ireland to illustrate the pre- 

 valence of colour variation in that region : — Garahus nemoraUs, Milll., 

 C. (jranulatus, L., C. arvensis, F., Notiophilus aquaticus, F., N. higut- 

 tatus, L., Leistus ferrugineus, L., and Gorymbites cupreus var. cerugi- 

 nosus, F. — Mr. H. St. J. Donisthorpe also showed three melanic forms 

 of Garahus nitens, G. arvensis, and Pterostichus climidiatus from the 

 New Forest ; all quite black. — -Mr. Sharpe, explaining his exhibit, 

 said that in his opinion these dark forms were racial, and represented 

 the survival of an older race, and that the melanism was not due to 

 protective necessities, derived from the environment of the localities 

 in which the several species existed. — Mr, H. Eowland-Brown ex- 

 hibited a series of Pieris manni, Mayer, from Le Vernet, Pyrenees- 

 Orientales, and called attention to the superficial differences which 

 presented themselves when compared with imagines of P. rapcB. — 

 Mr. E. C. Bedwell exhibited a series of Gassicla fastuosa taken by him 

 on Box Hill, Surrey, mostly from the leaves of young foxgloves. — Dr. 

 G. B. Longstaff exhibited a series of thirty-three specimens of Danaida 

 chrysippus taken by him in Egypt and the Sudan during January and 

 February, 1909. Two taken at Cairo, one at Kom Ombo, and one at 

 Aswan were all typical, but somewhat dark. A few other specimens 

 were seen at each of these localities, but none of them had white 

 hind wings. At Khartum, where the butterfly was fairly common, 

 twenty-five specimens were taken ; of these two might be described 

 as typical, though hghter than the Egyptian specimens ; in eight the 

 veins near the middle of the hind wings were dusted with white 

 scales ; in seven the centre of the hind wings was more or less 

 white, as in Moore's alcippoides ; while seven might be described as 

 typical alcippus, Cram. One specimen only was seen of the form 

 dorippus, Klug, and this had the hind w4ngs almost entirely white — 

 f. alhinus, Lanz. So far as could be estimated in the field, three- 

 fourths of all the specimens seen at Khartum were either alcippus or 

 alcippoides. On the White Nile between El Duem and Gebel En 

 (lat. 14-12^" N.) four specimens were taken, three typical or nearly 

 so, one of the alcippus form. These figures are in marked contrast 

 to the proportions found by the President among Mr. Loafs captures 

 on the White Nile in lat. ll-4f° N.— Mr. T. Bainbrigge Fletcher, E.N., 

 exhibited two mimics of D. chrysippus ; the females of Elynmias 

 undularis, and of Argynnis hyperhius [niplie), whose males in both 

 cases show the ordinary coloration of the genera to which they 

 belong. He said that although in the ordinary preserved condition 

 the resemblance of these two females to Danaida was rather "rough 

 and ready," and by no means comparable to the close imitation of 

 pattern seen in the female of Hypolininas (also exhibited), yet under 

 natural conditions of flight the likeness between model and mimic 

 was exceedingly close and deceptive. — Mr. Fletcher also exhibited 

 specimens of a large and conspicuous Mydaid fly. My das ruficornis,
