exhibitor; also Tetramoferia donisthorpet, Kieffer, n. sp., and 7’. femo- 
ralis, Kieffer, n. sp., taken by himself with Tetramoriwm cespitum, L., 
at Whitsand Bay, Cornwall; Paracletes cimiciformis, taken with 
T. cespitum, L., at Barnes Head, Cornwall; and Antennophorus 
pubescens, 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 :—Carabus nemoralis, Mill., 
C. granulatus, L., C. arvensis, ¥., Notiophilus aquaticus, F., N. bigut- 
tatus, L., Leistus ferrugineus, L., and Corymbites cupreus var. erugt- 
nosus, EF. Mr. H.St. J. Donisthorpe also showed three melanic forms 
of Carabus nitens, C. arvensis, and Pterostichus dimidiatus 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. Rowland-Brown ex- 
hibited a series of Pzeris mannt, Mayer, from Le Vernet, Pyrénées- 
Orientales, and called attention to the superficial differences which 
presented themselves when compared with imagines of P. rape@.— 
Mr. EH. C. Bedwell exhibited a series of Cassida 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 Kharttim, where the butterfly was fairly common, 
twenty-five specimens were taken; of these two might be described 
as typical, though lighter 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 wings almost entirely white— 
f. albinus, Lanz. So far as could be estimated in the field, three- 
fourths of all the specimens seen at Kharttim were either alcippus or 
alcippoides. On the White Nile between El Duém and Gebel En 
(lat. 14-124° 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. Loat’s captures 
on the White Nile in lat. 11-43° N.—Mr. T. Bainbrigge Fletcher, R.N., 
exhibited two mimics of D. chrysippus; the females of Hlymnias 
undularis, and of Argynnis hyperbius (niphe), 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 Hypolimnas (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, Mydas ruficornis,
