Sub-order 5 : Ehyncophora (Snout Beetles). 



In all the Snout Beetles tlie head is lengthened in front 

 into a characteristic snout or beak, also the foot (tarsus) is 

 typically four- jointed. The number of these beetles is 

 enormous, including about 25,000 species. The Weevils and 

 the Bark Beetles are perhaps the best known of them. 

 The Weevils constitute 



an enormous assemblage of 



forms, many of which are 



serious pests. They can 

 always be recognised by the snout or 

 beak (rostrum) that projects in front 

 of the head, and also by the antennae 

 which are usually very distinctly 

 "elbowed," i.e. each has a long basal 

 joint which can be extended out- 

 wards at the sides of the head, whilst the other, terminal 

 joints turn forward and are thickened at the tip (Fig. 196).
