ova. The offspring included both dubia and anthedon. Thus Mr. 

 Lamborn had been able to verify the suggestion that the forms Eur alia 

 antliedon and K. dubia are the dimorphic forms of a single species. 

 Instances of Mimicry. — Mr. W. A. Lamborn had intended to show at 

 this meeting the cases which he had exhibited at the Converazione, 

 but, owing to a misunderstanding, they had not arrived. He 

 mentioned, however, that he recently took at one sweep of his net two 

 butterflies, an Amauris psyttalea, Plotz, and a Kuralia dubia, which were 

 flying round and round each other in a manner suggestive of court- 

 ship, and it seemed evident that the one must have been deceived by 

 the mimetic resemblance to its own species exhibited by the other. 

 He further said : " In the exhibit which I had hoped to bring to your 

 notice is a West African Hypsid moth determined by Prof. Poulton as 

 Deilemera, probably antinorii, Oberth., with the cocoon from which it 

 emerged. The cocoon bears a large number of creamy white semi- 

 transparent frothy spheres which bear a very strong resemblance to 

 the cocoons of Braconid parasites. They doubtless have a protective 

 function. A bird, for instance, would soon learn that a cocoon bearing 

 the Braconid cocoons does not contain a pupa worth eating, and it is 

 reasonable to suppose that it would likewise pass by a cocoon bearing 

 structures which mimic them in such a remarkable way,"

Albert Harrison. 



In the early morning of Monday, August 28th, there passed away 

 suddenly, from haemorrhage on the brain, Albert Harrison, of 

 Delamere, S. Woodford, Essex. He was born in 1860 at the New 

 Pale Farm, near Frodsham, in Cheshire, close to iJelamere Forest. 

 After being educated at the Liverpool Institute, in 1875 he entered 

 the Laboratory of Henry Tate and Sons' Sugar Refinery in Liverpool, 

 and was in 1878 transferred to the London branch, of which he rose 

 to be Manager, and much of the success of which was due to his 

 business aptitude and attention. As a practical chemist he had great 

 skill and knowledge, and on several occasions had been sent abroad by 

 the firm to study new machinery and methods. He was greatly 

 respected by everyone, from the late Sir Henry Tate and the Directors 

 of the Firm to the lowest employe with whom he came in contact. 

 We in London knew him as an active member and frequenter of our 

 various Natural History Societies. He loved the country from his 

 earliest days. He was brought up in the confines of the great 

 Delamere Forest, and he chose the neighbourhood of Epping Forest 

 as the nearest available reminder of his boyhood's days for his southern 

 home. Besides being a Fellow of the Chemical Society, Member of 

 the Society of Chemical Industry, and other associations connected 

 with his professional career, he was a Member of the Society of Arts, 

 a Fellow of the Linngean Society, the Zoological Society, the Royal 

 Microscopical Society, and the Entomological Society of London, 

 a Member of the South London Entomological and Nat. Hist. Society, 

 the City of London Entomological Society, the Lancashire and 

 Cheshire Entomological Society, the Essex Field Club, the Quekett 

 Club, and the Ray Society. From 1908 to 1910 he was on the 

 Council of the Entomological Society of London, and on several
