were presented in 1902, in addition to several others in 
earlier years. For a museum which specializes so largely 
upon bionomic questions this donation is of the highest 
importance. Of almost equal interest is a collection of 
166 Bornean insects illustrating bionomic principles. Many 
of these are the specimens mentioned by Mr. Shelford in 
the same memoir, and sent over for exhibition when it was 
read. They include a beautiful series of mimetic Longicorn 
beetles chiefly of the genus Oderea, together with their models, 
the black-winged Braconidae; another series with their 
models, the bronze-winged Braconidae. A beautiful example 
of a mimetic Longicorn with its Curculionid model, the 
association comparing in the most interesting manner with 
some of Mr. Marshall’s groups from South Africa: Axthri- 
bidae and their Longicorn mimics Ereis and Cacia; Eroty- 
lidae and Endomychidae with similar, probably synaposematic, 
patterns and colours; a small J/antispa and its Hymeno- 
pterous model (both from Singapore); Hemiptera (Redu- 
viidae) synaposematic with Braconidae ; Diptera mimetic of 
Hymenoptera; a remarkable mimetic association between 
a Homopterous insect and a Lithosid moth (Darantasia) ; 
a beautiful red-banded Sesiid moth mimetic of an Aculeate ; 
additional specimens of many groups illustrated in Plates 
XIX-XXIII, P. Z. S., 1902; a group, probably synapo- 
sematic, of strongly spined beetles of the genus Amphisternus 
with possible mimics; specimens of the Longicorn mimic 
Zelota spathomelina, Gahan (co-types) and its Endomychid 
model, Spathomeles, sp. near ttrritus; a-large and beautiful 
synaposematic group of many species of glossy brown Phyto- 
phaga (Galerucidae) and their Longicorn mimics; a fine set 
of Bornean butterflies exhibiting injuries probably caused by 
the attacks of insect-eating animals; a set of spined Wispidae 
kindly named by Dr. R. Gestro of Genoa, including a co- 
type of Platypria chaetomys, Gestro ; conspicuous Coleoptera 
of species which had been rejected by insect-eating animals. 
Nearly the whole of this invaluable and most instructive 
collection was made in the neighbourhood of Kuching, many
