Memoir of George Robert Waterhouse. xxv 
first of all a collection had to be formed of the smaller 
insects, such as Homalota, Oxypoda, Atomaria, Cercyon, 
Cryptophagus, Pselaphide, &c., enormous numbers of 
which had to be collected and set in order to ascertain 
how many species might properly be considered British ; 
the great stumbling-block to be got over was Homalota, 
and for a long time he devoted himself most perseveringly 
to this genus, every locality within his reach likely to 
yield additional species being visited. When collecting 
he made a rule of not remaining in one spot (unless he 
was looking for some particular species), but divided his 
time first to moss, then roots of grass, dead leaves, bark 
of trees, heaps of rubbish, hay-stacks, wood-stacks, &c., 
his object being to secure as many species as possible, 
rather than long series of a few species. Every speci- 
men mounted was marked with a number corresponding 
with his register, in which the date and place of capture, 
and any circumstance of interest, were noted, the names 
of the rarer species often being added. In his tirst List 
of Aleocharide (‘ Zoologist,’ June, 1857), he states that 
all the species not marked with an asterisk were taken 
by himself in the two preceding years. Of the eighty- 
one Homalote, only nine are so marked. 
Besides the works already alluded to, he was the 
author of some 120 articles in various scientific journals. 
After the completion of the Catalogue of British Coleoptera 
he gave comparatively little attention to Entomology, 
partly on account of his eyesight, which had been 
somewhat injured by the constant examination of small 
species, and partly because he had been led by a friend 
to take up some literary researches. 
In his official capacity in the Museum, he was much 
engaged in the preparation for the removal to South 
Kensington of the geological collections, which since 
1857 had been separated from the minerals. The 
examination of the plan of the new museum soon con- 
vinced him that the space allotted to him was inadequate 
for the increasing collections, and by his advice, which 
his early training as an architect qualified him to give, 
the building was considerably altered so as to give 
increased accommodation for the collections in the 
gallery now occupied by the Reptilian remains. The 
general arrangement, and the position of all the larger 
specimens in the new building, is now much as he
