Society of London and in the Annals and Magazine of 
Natural History, and the first part of a revision and enumera- 
tion of the genera is now in the press (Genera Insectorum), 
The small collection of Alattidae belonging to the Paris 
Museum of Natural History, and entrusted to me for deter- 
mination, has been completely worked out, and there is now 
in my hands for description a large collection of Alatidae 
made by Dr. Yngve Sjostedt of Stockholn, in the Kilimanjaro 
district of East Africa ; duplicates from these collections will 
eventually be presented to the Hope Museum. The additions 
to the collection during 1906, though not very numerous, 
were of the greatest interest, since the specimens in most 
cases were accompanied by excellent data. 
The Mantidae have been brought together from different 
sources and arranged; they now occupy Ioo cabinet drawers 
and number 2.359 specimens, referred to 133 genera and 418 
species, 212 of which are identified; the number of type 
specimens is considerable (65), the late Professor Westwood 
having devoted special attention to the group. 
Of the Acridizdae the following sub-families have been 
arranged :—the Lumastacinae, numbering 170 specimens, be- 
longing to 14 genera and 45 species; the collection includes 
9 of the types of the species described by Mr. Malcolm Burr 
in his monograph of the group and 2 of Westwood’s types. 
The Proscopinae, numbering 100 specimens (of which 2 are 
types), belonging to 9 genera and 37 species. The Pxeu- 
morinae, 57 specimens (I a type), 4 genera and Io species. 
A collection of Zetriginae was sent to Dr. Joseph Hancock, 
of Chicago, for determination. 
Miss Shelford was kind enough to devote much time to the 
mounting on durable paper of the drawings of Orthoptera 
made by the late Professor Westwood from specimens in 
continental Museums ; these will be bound in book form and 
will constitute a valuable work of reference, as several of the 
type specimens from which the drawings were made have 
been lost.
