Inent to Part 2, No. 2,’Vol. tix, of the Journal of the Asiatic So- 
ciety of Bengal, and includes catalogues of the families Dytiscide, 
Gyrinide, Pausside, Hydrophilide, Silphide, Corylophide, Scydmae- 
nid, Pselaphide, and Staphylinide. The catalogue is synonymical, 
bibliographical, and geographical, and has every appearance of a com- 
plete and painstaking work. It is the fourth of the catalogues prepared 
by Mr. Atkinson, who, as he wrote us before his death, intended to 
publish in this form as far as he should be permitted, catalogues of the 
entire class Insecta. We earnestly hope: that workers in the field of 
oriental entomology will take up the task which Mr. Atkinson projected 
and will carry it to completion on the lines which he marked out. 
THE COLORADO POTATO BEETLE IN NOVA SCOTIA. 
The Provincial Government Crop Report of Nova Scotia for August 
(Halifax, N. 8., August 15, 1891), publishes condensed abstracts of cor- 
respondence relating to the Colorado Potato Beetle. Correspondents 
were requested to mention date of first oviposition, extent of damage, 
remedies applied and method of application, and results. Reports 
were received from all but five of the eighteen counties of the Prov- 
inee. Ina few instances only did the insects occur in sufficient abun- 
dance to do serious damage, but the report shows that the species 
has become distributed throughout a large section of the Province. 
The following abstract from correspondents’ reports will serve to show 
the popular sentiment: 
Upper Kennetcook, Hants County: Eggs began to be deposited as soon as there 
was a stalk to deposit on. Can not tell what the damage willbe yet. Hand-picking, 
and Paris green applied with a sprinkler. I think life is too short to hand-pick po- 
tato bugs, and that every man who has a potato patch should be compelled by law 
to use Paris green. 
Lower Horton, King’s County: * * * Law should be passed compelling everyone 
to destroy pests, and fine for neglect. Inspector should be appointed in every district 
with power to act if owner will not, and charge him for the work. 
A REMARKABLE BUTTERFLY ENEMY. 
At a meeting of the Entomological Society of London, held Septem- 
_ber 2, 1891, Mr. W. L. Distant exhibited specimens of an Orthopterous 
insect—Hemisaga hastata Sauss., one of the Locustide—which he had 
observed in the Transvaal to attack and feed on Danais chrysippus, a 
butterfly previously supposed, from its protective character and dis- 
tasteful qualities, to have complete immunity from the predaceous ene- 
mies of butterflies. The Hemisaga is said to lurk among the tops of 
tall flowering grasses and to sieze the butterfly as it settles on the 
bloom. After close watching and observation, Mr. Distant could find 
no other enemy of this butterfly.
