120 H. WALLIS KEW : AN HISTORICAL ACCOUNT OF 



Linnaeus' " Sy sterna Xaturae " ed. x. appeared at Stockholm 

 in 1758-9; and contained two false- scorpions : Acarus can- 

 croides (Europe) and Acarus scorpioides (America). In ed. xii., 

 Stockholm, 1766-8, these species were transferred to Phalangium 

 and the name of the second was changed to acaroides. Linnaeus 

 ignored Chelifer, which had been proposed in Paris, by Geoffroy, 

 in 1762 ; and it was not till 1785 that Fourcroy, also in Paris, 

 first used the familiar combination Chelifer cancroides. 



3. Martin, B. — The Young Gentleman and Lady's Philosopliy, 

 iii. London, 1782. 



Contains a long account in dialogue-form, and a grotesque 

 figure, of a " Lobster Insect," found by some labouring men in 

 a public-house, and borne away by an ingenious gentleman, 

 from whom the author borrowed it. = Chelifer sp.

 From this book it appears that the public-house above referred 



to was at Waltham Abbey ; and the gentleman w^ho bore away 

 the specimen was John Adams of Edmonton. From him it 

 passed to the author under notice, whose new figure of it re- 

 sembles in some respects Chelifer (Chernes) nodosus Schr., 1803. 

 The author tells us, moreover, of another specimen, in the pos- 

 session of Mr. Marsham, who found it fixed by its claws to the 

 thighs of a fly, which he caught on a flower in Essex. This is 

 the first record, in these Islands, of the clinging of false-scorpions 

 to flies' legs, the first known and only earlier one being in 

 Poda's " Insecta Musei Grcecensis " (Gratz, 1761). 



5. Shaw, G. — The Naturalist's Miscellany, iii. London, 1791. 

 Contains a figure of " Phalangium cancroides J^ = Cheiridium 



museorum (Leach, 1817).

 London, 1797. 



Among the finely engraved and beautifully coloured plates of 

 this work is one of " Phalangium cancroides " which is stated to 

 be the largest insect of the genus found in England that re- 

 sembles a scorpion. = Chelifer cancroides (Linn.).

F. Kanmacher, who edited this edition of Adams (4), was 

 acquainted with several of these animals. He refers to one
