RHYNCHOPHORA. 
A series of beetles recognised by the tarsi, which are similar to 
those of the Phytophaga (fig. 183), by the antennae, usually clubbed and 
often elbowed, and by the rostrum, the head being drawn out more or 
less distinctly, so that the mouth, instead of being ventral, is anterior 
to the eyes, and often at the apex of a distinct beak-like prolongation 
of the head. Tt is difficult to place a few forms and to distinguish 
exactly between this series and some of the Phytophaga, but such 
cases occur very rarely. The Rhynchophora are on the whole a 
distinct series, all phytophagous, with leg-less larvae usually living 
concealed (pace Cionus ) and including a large number of boring insects 
found as larvae in plants. 
Anthribidje. 
Rostrum short and blunt. Antennce straight , usually clubbed , eleven 
joints. Tarsi of four joints , third small and hidden. 
Dull coloured beetles of small size and not often found, the body 
clothed in pubescence. These beetles are found on tree trunks, on 
mushrooms, on dead wood ; few are very active, though a few can leap 
(.Arcecerus ). The larvae are white grubs similar to those of Curculionidce 
but sometimes with legs. They are found in seeds and in wood. 
Though few Indian species are known, many probably occur and their 
identification is not easy. Malaya is the head-quarters of the family. 
The student who specialises in this family will find a list of the known 
species with bibliographical references in Ann. Soc. Ent., Beige, XLIX, 
p. 218 (1905). Bovie here lists 91 species as occurring in India,
