found chiefly on leguminous plants. The larvae live in the seeds, eating up all the 
internal parts and changing to pupae within the outer shell. These beetles were at 
one time classed with the weevils, 
but are now generally recognised 
as being more nearly allied to the 
next family. They are illustrated 
on p. 1, where Fig. 1 is the pea- 
bruchus (B ruckus pisi ); Fig. 2, 
the bean-bruchus (B. rufimanus ); 
and Fig. 3, B. granarius, and 
larva ; all of them being enlarged.

The Chrysomelidce, more com¬ 
monly known as the Phytophaga 
—though this name is equally 
applicable to many other beetles 
— all live upon plants, feeding 
chiefly upon the foliage, while some 
also attack the flowers. They are 
almost as numerous as the weevils, 
and in their own way quite 
as 
destructive to vegetation. The 
family is divided into four sections. 
The Eupoda include those forms 
which most resemble the Longi- 
corns. Many of the beetles belong-

thickened hind-legs, but 
instead of being active 
jumpers, as might be 
suspected, they are really 
very slow and awkward 
in their movements. In 
the males of the genus 
Sagra, the hind-legs are 
enormously developed, 
the species of this genus 
being for that reason 
sometimes known as 
kangaroo-beetles. The 
Doncicince live upon 
aquatic plants of various 
kinds; they have a 
bright metallic colora- 
tion, which in many 
species is veiled by a 
delicate covering of
