sufficient means to enable him to pursue his studies unfettered by
business claims on bis time. He was, however, nominally a shipbroker,
and had an office in Fenchurch Street for some years.
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
Council of the Eay Society.
