Sub-order 5 : Rhyncophora (Snout Beetles). 



In all the Snout Beetles the 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. 



Weevils ^ ne Weevils constitute 



(Family an enormous assemblage of 



Curcu- forms, many of which are 

 1 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).
