a specimen of a handsome oxotic Cockroach (Dprylaea rhombifolia) found alive in 

 the Natural History Museum, an apterous species inhabiting China, [ndia, 

 Madagascar, South Africa, &c., and also recorded houi Tropical America. Dr. G. B. 

 r /ongstaff, a oa^e containing 35 [thomiine butterflies of 11 Bpecies, belonging to 

 {'> genera, taken near Caracas, Venezuela, some 3600 feet above sea-level. They 

 afforded a striking exception to Darwin's principle that closely allied forms are not 

 usually found together. Lieut. -Colonel N. Manders, a collection of some 200 

 specimens of tropical butterflies belonging to the genera Melanitis, Mycalesis, 

 Atella, Papilio, and Catopsilia, which had been subjected to abnormal degrees of 

 temperature mostly in the pupal stage. The object, of the experiments was to 

 ascertain the effect of climate on the colours of tropical butterflies. Mr. W. J. 

 Kaye, a convergent group of Ileliconine butterflies, from the Potaro River, British 

 Guiana, lie said that hitherto there had not been detected any species of Danaine 

 or Ithomiine butterfly that might serve as a model or mimic of these species, and 

 if at anytime the large Melinxa mneme — Heliconius numata group oxerted any 

 influence on these red and yellow and black species, it was unlikely that it did so 

 now, because they have not the same flower-frequenting habit and are not found in 

 company with them. In illustration of his paper " Mimicry in North American 

 Butterflies of the genus Lime nit is {Basilar chia)," Professor E. B. Poulton showed 

 specimens of Adelpha {Heterochroa) bredowi, ranging from Guatemala to Arizona, 

 and its northern form, named californica by A. G. Butler, from California and 

 Oregon. With these he exhibited specimens of Limenitis (Basilarvhia) lor qui ni, 

 Boisd., taken together with the Adelpha's, by Mr. F. D. Godman, in the two last- 

 named States. A specimen of L. lorquini from Esquimalt, Vancouver Island, was 

 also exhibited for the purpose of comparison with the southern individuals. These 

 mutual resemblances appeared to offer a striking example of Dr. F. A. Dixey's 

 principle of the Reciprocal Mimicry. Mr. H. St. J. Donisthorpe read a paper on 

 the Life-History of Lomechusa strumosa, F. 



Wednesday, December Uh, 1907. — Mr. C. O. Waterhouse, President, in the 

 Chair. 



Mr. Walter Feather, of 10, Station Grove, Cross Hills, Keighley, Yorkshire, 

 and the British Soinaliland Fibre and Development Company, Berbera, Somaliland, 

 British East Africa, and Mr. Rupert Wellstood Jack, Assistant Entomologist in the 

 Department of Agriculture of the Cape of Good Hope, Cape Town, South Africa 

 were elected Fellows of the Society. 



Dr. G. C. Hodgson exhibited a number of examples of Anthrocera trifolii, 

 collected on the same ground in Sussex, and showing a wide range of variation, 

 including three fine melanic forms, and several showing six spots on the upper- 

 win ' T s. Mr. W. J. Kaye, a specimen of Papilio thoas with the central portions of 

 both tails removed apparently by a narrow-billed bird. The injury appeared so 

 symmetrical that it was thought likely that the specimen was an abnormality. 

 But a careful microscopical examination showed that this was not the case. With 

 it were several species of butterflies from British Guiana with injuries to the 

 wings in the region of the abdomen, such injuries to Danaine butterflies being quite 

 rare. The President, two photographs of an African Locust, which had apparently 

 caught a mouse and was preying upon it. The specimen was found in the Congo
