further exhibited a species of Cosmosoma, Family Syntomildae, partly 

 covered with a white wool. According to the collector (A. H. Fassl), 

 " the insect when touched ejects from a fold on the underside of the 

 abdomen a white wool, which completely envelops the specimen." 

 The hitherto unknown female of 0(/ijns weeki, Roths., a Lycfenid 

 from New Guinea, was likewise shown, together with the male, and 

 several species of Hi/pochri/sops. 



OBITUARY. 



Pieter Cornelius Tobias Snellen. 



The Entomological Society of London has lost its oldest Honorary 

 Fellow by the death of the famous Dutch Lepidopterist P. C. T. Snellen, 

 who was elected in 1885. This event took place on March 29th, at 

 Rotterdam, which had been his home during the whole of his life, and 

 where he had been in business for many years. He was 77 years of 

 age and unm/arried. He was one of the founders of the Entomological 

 Society of the Netherlands and wrote much in the Tijdschrift, the 

 organ of that body. His first paper " On the female of Fidonia 

 profie)ni)iaria, Hiibner," appearing in 1857. His fame rests principally 

 however on his great work the " Vlinders van Nederhmd," the first 

 volume of which, on the " Macro-Lepidoptera," appeared in 1867, and 

 the second a much longer work on the " Micro-Lepidoptera " in 1887. 

 This work is of great value, but being written in Dutch it is unfortun- 

 ately a sealed book, not only to most Englishmen, but to the majority 

 of continental Entomologists also. — G.W. 



William Alfred Rollason. 



We regret to have to announce the death of Mr. W. A. Rollason, 

 which took place after only two days illness on April 23rd. So sudden 

 and unexpected indeed was the event, that Mrs. Rollason, who had 

 been called away to the sick bed of her father, only just returned in 

 time to see her husband alive ; to her and to her young children our 

 most cordial sympathy is offered. Mr. Rollason, who was only 48 

 years of age, was elected a Fellow of the Entomological Society in 

 1909, and was known as a contributor to the Magazines ; a list of the 

 Cornish Hymenoptera-Aculeata appeared in the April number of the 

 Knt. Mn. Ma()., and in the current (June) number of the Kntoiuulouist 

 is a paper by him on the Ichnenmonidae taken in Cornwall in 1910. 

 The order however which claimed most of his attention was the 

 Lepidoptera, and we understand that he had the intention of publishing 

 a book on the British species with his own illustrations, many of which 

 seem to have been already prepared. For Mr. Rollason was a ma.n of 

 many attainments and of wide and varied interests. He was first and 

 foremost perhaps as an artist, and held the position of Art Master of 

 the Central Technical Schools, Truro, and it was to his residence in 

 that city for the past ten years that we owe his county lists of Cornish 

 insects. He had previously won distinction in connection with the 

 Birmingham School of Art, and was a contributor to many exhibitions, 

 and a most efficient Secretary to the Cornwall Art Union. He was 

 also an enthusiastic Freemason, and had occupied high positions in 

 the Brotherhood. But even this does not exhaust the list of his 

 attainments, for he was an accomplished musician and took part in 

 the concerts both of the Truro Orchestral Society and the Philharmonic 

 Society. He will be widely missed, for his death will cause a gap in 

 in many circles which no other one man can be expected to fill. — G.W.
