20 THE ENTOMOLOGIST. 



four approached nearly to ab. 'porivia ; the rest were intermediate 

 between prorsa and jjorima. — Dr. T. A. Chapman also exhibited 

 specimens of Araschnia levana, type, bred 1907, to give a fuller view 

 of this form in assistance to Mr. Sheldon's report. — Mr. G. J. Arrow 

 exhibited a specimen of a handsome exotic cockroach {Dorylaa rhom- 

 bifolia) fovmd alive in the Natural History Museum, an apterous 

 species inhabiting China, India, Madagascar, South Africa, &c., and 

 recorded from Tropical America. — Dr. G. B. Longstaff exhibited a case 

 containing thirty-five Ithomiine butterflies of eleven species, belong- 

 ing to six genera, taken on March 20th, 1907, near Caracas, Venezu- 

 ela, some 3600 ft. above sea-level. They afforded a striking excep- 

 tion to Darwin's principle that closely allied forms are not usually 

 found together. — Lieut. -Colonel N. Manders exhibited a collection of 

 some two hundred specimens of tropical butterflies belonging to the 

 genera Melanitis, Mycalesis, Attella, 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 exhibited a convergent group of Heliconine butterflies, from the 

 Potaro River, British Guiana ; he 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 any time the 

 large 3£eUmcea mnevie, or Heliconius numata group, exerted any influ- 

 ence on these red and yellow and black species, it was unlikely that it 

 did so now, because they had not the same flow^er-frequenting 

 habit, and were not found in company with them. In illustration of 

 his paper, " Mimicry in North-American Butterflies of the genus 

 Limenitis {Basilar chia),'' Professor E. B. Poulton, F.R.S., showed 

 specimens of Adelpha (Heterochroa) bredotvi, ranging from Guatemala 

 to Arizona, and its northern form, named californica by A. G. Butler, 

 from California and Oregon. The mutual resemblances appeared to 

 offer a notable example of Dr. F. A. Dixey's principle of reciprocal 

 mimicry. — Mr. H. St. J. Donisthorpe read a paper " On the Life- 

 history of Lomecosus strumosa, F." 



December Ath. — Mr. C. 0. Waterhouse, President, in the chair. — Mr. 

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

 and the British Somaliland Fibre and Development Company, Berbera, 

 Somaliland, British East Africa ; and Mr. EupertWellstood Jack, Assist- 

 ant 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, introduced by Dr. T. A. Chapman, exhibited a 

 number of examples of Antlirocera 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 

 wings. — Mr. W. J. Kaye showed a specimen of Papilio thoas 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 micro- 

 scopical examination showed this not to be 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
