having in general the form shown in our figure of A. apricans. Though the 
British species are numerous and some of them common everywhere on clover, 
trefoil, and other leguminous plants, they are 
seldom noticed owing to their small size. In 
Apoderus, Attelabus, and Rhynchites we have a 
group of genera which are interesting on account 
of the leaf-rolling habits of the females, and 
remarkable also, in the case of the first genus, for 
the great length of neck displayed by some of 
the species. The females deposit a single egg, or 
in some cases two or even three eggs in each of 
the little rolled - up leaf packages, which serve 
afterwards both as a shelter and food-supply for the larvae. Three or four species 
of these leaf-rolling weevils are found in Britain. Our figure of A. longicollis.

a Javan species, shows what an extraordinary length the neck may attain in 
the males of some of the tropical representatives of the genus, although in this 
species it is not nearly so long in proportion as in an allied form (A. tenuissimus ) 
found in the Philippine Islands. The nut-weevil {Balaninus 
nucum ) affords a strong contrast in the shape of its head to the 
species just mentioned. It will be noticed that in this weevil 
the head is very short behind the eyes, whereas the beak is 
greatly elongated, with the antennae inserted near the middle of 
its length. The female lays her eggs in hazel-nuts while the 
latter are still in a half-developed condition; she first pierces a 
hole in the soft shell of the nut, and then depositing an egg in 
the opening pushes it in with her beak. The grub feeds inside 
the nut, remaining in it until autumn, when it bores a round 
aperture in the shell, and, escaping from the nut, makes its way Apoderus longicollis 
into the soil, where it surrounds itself with a cocoon formed of (enlarged).
