 sufficient means to enable him to pursue his studies unfettered by 

 business claims on bis time. He was, however, nominally a ship-

In the Presidential Address to the Entomological Society of 

 London in 1886, Mr. McLachlan gives a short autobiography of 

 his early hfe. He there tells us that when a boy his natural 

 history instincts embraced " the whole Systema Naturae." Land 

 and fresln\ater shells, and butterflies and moths, seem to have 

 been his chief zoological fancies, but above these botany appears 

 to have dominated. In 1855 he went for a voyage to ISew South 

 AVales and Shanghai, and on this tour be amassed a considerable 

 herbarium, the species of which were subsequently named "with 

 the assistance of the late Kobert Brown. Soon after his return 

 he must have commenced his entomological studies, the earliest of 

 which he devoted to Lepidoptera, as he published a paper on 

 Acentropus in the ' Entomologist's Weekly Intelligencer,' in 1861, 

 In the same year he published his first Neuropterous paper in the 

 ' Entomologist's Annual,' and from that time his papers on Lepi- 

 doptera and Neuroptera became numerous. The latter subject, 

 however, soon occupied all his time. His chief work, ' A Mono- 

 graphic Revision and Synopsis of the Trichoptera of the European 

 Eauna,' a thick volume with supplements altogether of 626 pages, 

 with 59 plates of structural detail, Mas completed in 1880. His 

 other numerous writings are scattered throughout the Entomo- 

 logical literature of his time, several of his papers appearing in 

 the ' Journal' of the Linnean Society between the years 1871 and 

 1892. 



Mr. McLachlan became a Eellow of the Entomological Society 

 of London in 1858, and was President in 1885 and 1886, Secretary 

 from 1868-72, and twice Treasurer ; the latter office he held at 

 his death. He was elected a Fellow of the Linnean Society in 1862, 

 of the Eoyal Society in 1877, of the Zoological Society in 1881, 

 of the Eojal Horticultural Society in 1888 ; he was also on the
