of potatoes in a garden at Messina. This patch alone, out of many others, was 

 unhealthy and appeared diseased, as was the case also witli some tomato plants 

 which occupied the same ground last year ; and it is probable that these larvae 

 were the cause of the " disease." In continuation of the breeding experiments 

 on Hyjwlimnas misippus, Professor Poulton exhibited the females of two families, 

 reared in 1911, from female parents of the type form, by Rev. K. St. Aubyn 

 Rogers, M.A., F.E.S. These experiments confirmed the conclusions drawn 

 from Rev. K. St. Aubyn Rogers' earlier work, and stated in the Proceedings of 

 1911, J), xliv, that misippus was dominant and inaria recessive ; also the 

 fragments of a Glossina identified by Mr. E. E. Avisten as a female of 

 G. caliginea, Aust. ; this specimen had been bitten and rejected by a monkey ; 

 also several families of butterflies, bred by Dr. W. A. Lamborn in the Lagos 

 District. He referred to the strong light which was thrown by them upon 

 different biological problems; also a specimen of the Eupterotid, or, as Auri- 

 villius considers, the Notodontid moth, Anaphe infracta, concerning which 

 Mr. W. A. Lamborn had written from Oni Camp, April 22nd, 1912 : " The moths 

 undoubtedly possess urticating hairs. The female Mona was allowed to steal 

 one. She smelt it, rubbed off the hairs and scales, then dropped it, and in 

 a few minutes was rubbing all four feet on the ground. I made some 

 sympatliising remarks, with the result that she suddenly sprung on to my bare 

 neck, and I have been troubled with skin irritation all the evening. I found, 

 too, that an urticating line on my arm followed exactly where I allowed a moth 

 to crawl up a few days ago. It came and settled there when I was reading." 

 Professor Poulton said that Mr. A. H. Hamm had found hairs from the anal 

 tuft of the exhibited specimen produced irritation on his hand and face. 

 Mr. Eltringham had found that the hairs of the female, but not of the male 

 tuft, were covered with minute, excessively fine spicula-like teeth. Professor 

 Poulton also exhibited the imagines and cocoons of 0. varia sent to him by 

 Dr. G. D. H. Carpenter from Damba Island, 20 miles south-east of Entebbe. 

 The larval skin was still projecting from some of the cocoons and showing its 

 blue spots. Dr. T. A. Chapman remarked that the hairs covering the eggs of 

 Porthetria dispar are also urticating. He also observed that there are other 

 species of moths which extrude the larval skin, but in these cases it was from 

 flimsy cocoons. Mr. J. H. Uurrant also gave instances of this fact. Prof. Poulton 

 also exhibited the larva3, pupa3, and imagines of " Callioratis " pactolicus, sent by 

 Dr. Gr. D. H. Carpenter, to illustrate the warning colovxrs of the moth in all 

 its stages. He said that Dr. G. D. H. Carpenter had left Damba in December, 

 1911, and had gone in January to Bugalla Island in the Sesse Archipelago. 

 On January 28th he had found there representatives of all the Planema- 

 Pseudacrxa associations ; the disproportion between Planema and Pseudacnea 

 is even greater there. Sesse thus confirms the Damba records, the results 

 being still more striking. The following papers were read : " Studies in the 

 Blattidse," by R. Shelford, M.A., F.E.S. ; " Polyommatus alexins, Freyer, a good 

 Species," by T. A. Chapman, M.D., F.Z.S., F.E.S. — George Wheeler, H071. Sec.
