and descriptions of each stage where available, often directly by 
Dr. Packard himself from living or preserved material. The pity 
of it is that the grasp of the whole subject which this laborious 
detailed work must have afforded Dr. Packard, can hardly be obtained 
by any one else, by studying this volume. Whoever follows the matter 
up will have to go over the whole of the ground again, but will no 
doubt find the material here gathered will help him very largely. 
The 32 plates of larve ia colour are most effective, some of 
natural size, some enlarged. They are generally those of American 
species or of imported Asiatic such as selene, atlas, pernyt, with 
African and some others from preserved specimens. 
An immense caterpillar in the collection of the Royal College of 
Surgeons was exhibited at the Entomological Society by the late 
Professor Stewart in 1906 (see ‘ Proceedings,’ p. Ixvili). No one 
volunteered a name for it, but the figure of the larva of Acantho- 
campa belina on Plate XXXII of this volume shows the two larve 
to be not identical, but almost certainly congeneric. 
There are 5 plates of photographs of larvee, and 20 of neurations, 
presumably drawn by Dr. Packard, though this is not stated. 
There are 56 plates of photographs of imagines (and one in the 
text) in some of which photographs of larve and cocoons are also 
presented. These are, one may say, all very good; in some cases the 
photographer is mentioned, but this is not so in most cases. One 
plate says, “photographed by J. H. Watson,” and 25 plates, “ all 
in collection of J. H. Watson,” were supplied by Mr. Watson (of 
Manchester) and are presumably photographed by him. Hight other 
plates are of specimens in the United States National Museum, and 
selected for photography by Dr. H. G. Dyar. 
There are 34 text figures, generally of details of spines, hairs 
and other skin armatures, and there are not a few of these on the 
larval plates. These emphasise the outstanding value of the book, 
as giving structural and other details of larve in their various 
instars. 
Structural and other details of other stages are features of most 
of the life histories given, and are occasionally illustrated. 
It may not be generally known, that in Natal the natives do (or 
used to) make anklets of the cocoons of Argema mimose, a number 
being sewn on monkey skin, and with one or more small stones in 
each cocoon, “ rattle in a most delightful way” (p. 179). 
Professor Cockerell appears to have edited the work with great 
efficiency and discretion, adding what is necessary to make things 
clear and connected, and yet in no case obtruding on you the fact 
that there is an Editor. T.: Beat.
