396 FAMILY CURCULIOXIDAE 



Members of both the groups have in a large number of instances one 

 habit in common : they sham death when disturbed, and to enable the decep- 

 tion to be carried out to perfection the insect is able to fold up the antennae 

 and legs flat against the sides in such a manner that they are scarcely observ- 

 able. In the diurnal species this habit affords a valuable protection against 

 enemies, as they drop from the plant in a second and are lost in the jungle- 

 growth below. The habit is probably equally useful to the bark- and wood- 

 and seed-feeders during the short period they spend on the wing moving 

 from the tree in which they were reared to the fresh one they select for 

 ovipositing. 



The weevils are a very large family of beetles whose classification is a 

 matter of considerable complexity. The Indian forms known are under- 

 going revision by Mr. Guy A. K. Marshall for the Fauna, of British India 

 series, volumes whose publication should prove of great aid to the study 

 of the family. 



Mr. Marshall has very kindly identified the Dehra Dun collections 

 for me. describing some seven new species, dealt with below, in the Annals 

 and Ma^a~in~: < f X.itural History for February and August 1913.
