840 The Zoologist — July, 1867. 



Prof. Westwood enquired whether any Member present bad noticed any coustant 

 variation in colour, or markings or otber external character, by which the sex of larvtB 

 could be determined? Mr. F. Smith said that he had once found a lot of Anthophora 

 larvae, which, instead of the usual ivory-white, were of a saffrou-yellow colour ; but 

 they produced male and female Anthophora? indiscriminately. Mr. Stainton remarked 

 that larvae of Clioerocampa Elpenor and Porcellus occurred of two different colours, but 

 be could not say whether the differences were sexual. Mr. Bond, however, had kept 

 the two forms of C. Elpenor separate, and each form had produced both sexes. —

Death of the Rev. Hamlet Clark. — It is my painful duty to record a severe loss 

 that Entomology has suffered by the death of the Rev. Hamlet Clark, one of its most 

 accomplished and most persevering cultivators: he was the eldest son of the Rev. 

 Henry Clark, Vicar of Harmston, Lincoln, where he was born in 1823: from his 

 earliest days he evinced a strong love for Natural History : when at College he 

 possessed an excellent collection of British birds, nearly all of which were procured 

 by himself: spiders, too, were to him a study full of interest: butterflies and moths 

 were subsequently taken up, and researches in this branch of the Science became his 

 occupation day aud night ; but daring the last ten years of his life Coleoptera became 

 the subjects of bis special investigation, and he made the carnivorous water-beetles his 

 especial study : in pursuit of these he travelled over a gieat part of these islands, and 

 also extensively in Spain. Towards the end of the year 1856 he crossed the Atlantic, 

 with a view to forming collections, in company with Mr. Gray, and in the 'Zoologist' 

 for the following year published two most interesting papers on its entomological 

 productions; he stayed at the Corcovardo Mountain, Pijuca, Constancia, Presidencia 

 and Paraihiba: the two fust immediately above Rio, Constancia and Presidencia in 

 the Organ Mountains, and Paraihiba on the river of the same name. Coleoptera 

 were the principal objects of bis researches, and he describes the localities, modes of 

 capture, Sec, with much precision: he also tried sugaring for Nocturnal Lepidoptera, 

 and found it as productive as in England. Diptera were confined to those pests known 

 in the country as sand-flies, luusquitos and borrachudos. Hymenoptera, with the 

 exception of ants, were rare, but these seemed to abound ; and he describes the nest of 

 one species, built in trees, that is an article of commercial value, being cut up into 

 slabs or blocks and used for the purpose of lining ovens. He also gives a useful, rather 

 amusing account of the necessary outfit of an entomologist in these regions. Pre- 

 viously to this Mr. Clark had published three admirable papers in the 'Zoologist' on 

 our British water-beetles, giving lists of all the species, with syuunymes, critical 

 remarks, and useful notices of continental species nearly allied to our own ; and he 

 since published several highly useful papers in the 'Transactions of the Entomological 

 Society,' as well as Catalogues for the British Museum ; through the kindness of Mr. 

 Dunning and Mr. Smith I have received a complete list of these, but it is too long for 

 the short space I can afford for an obituary notice here. For the last four years Mr. 

 Clark's health had been declining, and his illness was attended with much suffering: 

 he died at Rhyl, on the 10th of June, 1867, aged forty-four years, and was buried in 

 Rhyl Cemetry on the 13ih. His end was marked by peculiar serenity and happiness.
