REVIEW. 
Mocaquerys’ Tératologie entomologique 
[PsycHe, Rec., no. 2037] is the record of 
abnormal coleoptera most of which belong to 
the collection left by the late M. Mocquerys, 
of Rouen, France, at his death, 12 Feb. 1879, 
to the city of Rouen, for its natural history 
museum. The systematic and careful arrange- 
ment of this work will commend it to the use 
of all coleopterists. Each abnormal spe- 
cies is neatly figured, natural upon 
the top of a page, and, where the abnor- 
mality is in an antenna, or other part too 
small for convenient observation, the part 
itself is figured enlarged. Beneath the figures 
is a brief description of the abnormal part, 
followed by a statement of where the speci- 
size, 
men was found, and in whose collection it is 
preserved. The work reflects credit upon the 
Société des Amis des Sciences Naturelles, 
under whose auspices it was published, and, 
upon M. Bourgeois, the secretary of the 
society, by whom the work was revised and 
put in form for publication, and by whom the 
views of M. Mocquerys upon the abnormal- 
ities of insects were explained in the intro- 
duction. A good work could be done for 
American entomology if the numerous abnor- 
mal specimens now scattered through Ameri- 
can collections of insects were brought 
together, figured, and the figures published 
with brief descriptions. G: D.

17 JUNE 1880.—... <A paper was read by 
Mr. F. Maule Campbell, **‘On certain Glands 
in the Maxillae of Spiders.” These glands, 
to which he attributes a secretory ‘function 
(probably salivary), are found in Tegenaria 
domestica, have apertures on the inner side 
of the upper face of each maxilla thence in- 
clining towards the mouth. They are ring- 
like in figure, with an enclosed disk, and with 
tegumentary folds at their outlets. The glands 
and apertures increase in number with age, 
and the ducts tend to become chitinous. 
Glands yarying somewhat in structure, but 
evidently similar in kind, exist in species of 
linyphitdac, theriditdae, and efecridae. 
Mr. F. M. Campbell communicated a second 
paper ‘*‘ On the stridulating organs of SZea- 
toda guttata and Linyphia terebricola.” A 
stridulating organ has already been described 
by Prof. Westering and Mason Wood in cer- 
tain other spiders; the present observations 
demonstrate its existence in both sexes, and 
the essentials of the structure are now given 
in detail. ... A paper by Sir John Lubbock, 
Bart., M. P., was read, namely, ‘* Observa- 
“tions on Ants, Bees, and Wasps, with a de- 
scription of a new species of Honey Ant. 
In this, his seventh contribution on this sub- 
ject, Sir John related his fresh experiments 
on their powers of communication. — From

CAMBRIDGE ENTOMCLOGICAL CLUB. 
8 Oct. 1880. Dr. H. A. Hagen read a let- 
ter lately received from a lady residing in the 
suburbs of Boston, in regard to a new and 
very annoying household pest, the exact na- 
ture of which it had not been possible yet to 
determine, as no specimens had been submit- 
ted to competent inspection nor could any at 
this time be obtained; but the most extreme 
exertions, including the frequent scalding or 
baking of nearly every article in the house, 
numerous complete removals of all the furni- 
ture from room to room, and the burning of 
over twenty five kilograms of sulphur in a 
single summer, had failed to mitigate the 
attacks of the pest, during its period.
