In the course of the spring and summer of 1882 the long-needed 
observations of where the maggots of the Sitona lineata and S. puncti- 
collis (that is to say, of two kinds of Weevils which often cause great 
injury to Peas, Beans, and Clover) feed and turn to a chrysalis state 
were made respectively by Mr. T. H. Hart, of Park Farm, Kingsnortli, 
Kent, and Mr. R. W. Christy, Boynton Hall, near Chelmsford, and 
were given, up to the time of preparation for publication, in the ‘ Report 
of Injurious Insects for 1882.’ 
The following observations by Mr. R. W. Christy complete his 
observations up to the same time in the season of the year in 1883, in 
which he began them in 1882, and I prefix a few lines of abstract of 
the first part of his observations. 
In March, 1882, he found the Weevil grubs* present at and much 
injuring the roots of Clover ; these ( Sitona ) grubs turned to chrysalids 
about the end of May, from which the first Weevils came up about 
June 20th. The Weevils were exceedingly numerous and injurious in 
the usual way, by gnawing the roots of leguminous plants, and towards 
the end of November the new generation of grubs from the eggs of 
these multitudes of Weevils was working at the roots of the Clover. 
Here the observations in the Report of 1882 stopped. Mr. Christy 
now continues:— 
“ On Nov. 23rd I examined great numbers of Clover roots, and 
* This attack was of Sitona puncticollis, which is very like the common Pea 
Weevil, S. lineata, excepting being a little larger, and having a few whitish spots on 
the fore part of the body near the head, whence the name pancti-collis. The 
maggots of these two kinds of Weevils are about a quarter of an inch long, legless, 
. wrinkled, and whitish, with a brown or ochre-coloured head, furnished with jaws, 
the chrysalis like the beetle in shape, with the forming limbs folded beneath it.
