OF INJURIOUS INSECTS.

Otiorhynchus picipes on Iris Raspberries at Exeter; but by the use of 
a sweeping-net after dark, during the month of June, he prevented 
any but slight injury from the attack. Mr. Clapham observes relatively 
to Otiorhynchus sulcatus, which had been exceedingly numerous in his 
garden at Scarborough, that on taking up his Primulas (800 to 900 in 
number) very few of the Weevil grubs were found, and only a limited 
number of the perfect Weevils were observed during the season. This 
he considers may be partly attributable to the seedlings being planted 
in fresh earth, partly to the excessive rainfall, but mainly he believed 
to the presence of Hedgehogs, whose services had been of much use 
in clearing off the plague of Slugs, and he considers had also destroyed 
the Weevils. Mr. Rolfe notes the 0. sulcatus being as destructive 
as usual to Primulas, &c., at Welbeck, and especially to some 
P. Japonica, from which larvae were picked in great numbers. In tlm 
same frame were about a dozen other plants in pots, of which the balls 
of earth were frozen into solid masses. After being in this state for 
about eight weeks they were placed, about the beginning of March, in 
a Vinery just starting, and on the 15tli two Beetles appeared, and 
others successively, until by the 29th a hundred and twenty-six had 
made their appearance, the greater part of the number coming out on 
the 20tli, when sixty were captured. They crawled up leaving a little 
hole in the soil (each Beetle with a little of the earth, that had adhered 
to it in forcing its way, still on the wing-cases), and in some instances 
so recently developed as to be still soft. A ter crawling out of the soil 
they remained quiet amongst the young leaf-stalks just above the 
surface, and some on the inner rim of the pots, conjecturally, waiting 
for darkness to start on their errands of destruction. From observations 
made during February of the present year on larvae of Otiorhynchus 
sulcatus, which had been left in earth in flower-pots in my garden at 
Isleworth exposed to cold, reading as low as 11°*8, they appeared, with 
scarcely any exception, entirely uninjured by the severe weather. The 
balls of earth were frozen hard, and the larvae stiff and motionless, but 
they gradually regained flexibility, and for the most part (and the few 
exceptions not evidently attributable to cold) appeared in complete 
health in all respects. Soot and sulphur are mentioned by Mr. W. R. 
Scowcroft as having been found of some service for application to 
garden plants at Fathom, near Ormskirk, Lancashire, but not as 
being satisfactory, from the frequent renewal needed with regard to the 
soot, and the great quantity of sulphur requisite for thorough effect. 
3. Sitones lineatus. Pea Weevil. These are mentioned by 
Mr. Fitch as very abundant in spring on the Peas, and very destructive
