 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 (Bruchus 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- 



The larvae live in the seeds, eating up all the

 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 

 Donacince 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
