THE LATE H. W. BATES. 187 



mimicry was established that the edible species were well 

 protected. These views were ably worked out in an important 

 paper published in the ' Transactions of the Linnean Society ' 

 for 1862, vol. xxiii, pp. 495 — 566, with two plates of coloured 

 figures designed to show a few examples out of a great number 

 of mimetic analogies between various Lepidopterous insects and 

 the Heliconidae, and illustrating also the process of the origina- 

 tion of a mimetic species through variation and natural 

 selection. 



In 1864 Mr. Bates contributed to the Journal of Entomology 

 an important paper on the classification of the Ehopalocera, 

 which was an enlargement and elaboration of previously pub- 

 lished views. Of this paper Mr. Distant has remarked that " it 

 is a model of the philosophical treatment of a purely systematic 

 subject," adding that "the arrangement proposed by Mr. Bates 

 has since been universally followed, and this in recent years, 

 when a large number of faunistic works on the Ehopalocera 

 have been written in various lands, and with a wealth of material 

 formerly unknown. His classification reversed the previously 

 understood sequence in the families, and still remains the most 

 philosophical and natural system yet attained in the arrange- 

 ment of any order of the Insecta." 



After his classic book of travels, foremost amongst his 

 publications in scientific importance must be reckoned his con- 

 tributions on the Coleoptera (in 3 vols. 4to), to Godman and 

 Salvin's * Biologia Centrali Americana.' He contributed also to 

 Stanford's ' Compendium of Geography and Travel,' a volume on 

 " Central America, West Indies, and South America," which has 

 passed through several editions. He edited for Messrs. Cassell 

 a valuable series of volumes entitled * Illustrated Travels,' and 

 wrote the section on Coleoptera in Cassell's * Natural History,' 

 edited by the late Professor Duncan. In addition he contributed 

 a great number of papers, chiefly on entomology, to various 

 journals and to the Transactions of scientific societies. 



Of these we may especially mention " Some particulars in 

 the Natural History of the Termites" Linn. Soc. Journ., 1854, 

 p. 333 ; " Observations on the habits of two species of My gale" 

 Proc. Entom. Soc, 1855, p. 99 ; " Notes on South American 

 Butterflies," 1857, Trans. Entom. Soc. vol. v., 1858, pp. 1—11 ; 

 and a "Description of a remarkable species of singing Cricket
