Order V. COLEOPTERA (BEETLES)— contd. 



Series II. — Adephaqa or Caraboidea. 



Tarsi five jointed, antennae filiform or nearly so. Mouth parts high- 

 ly developed, with slender projecting mandibles ; abdominal segments 

 visible ventrally usually 5 in number. These beetles are usually dark 

 coloured, active and slim, with long powerful legs which enable them 

 to run very rapidly. Both beet es and their larvae are carnivorous. 

 The grubs are generally dark coloured, with a group of ocelli on 

 each side of the head and with well developed legs, each having two 

 claws. This distinguishes their larvae from all other coleopterous 

 ones which have only one claw present. The grubs live beneath the 

 bark of trees or in wood where they follow and feed upon bark and 

 wood-boring insects; or they are to be found in the soil feeding 

 upon root-eating insects or on or in plants and crops engaged 

 in a similar manner. The group is probably of considerable utility 

 to man. 



Fam. IV. Cicindelidse— Tiger-beetles. 



Bright coloured beetles with large eyes and with the clypeus (lower 

 portion of front of the head) extending laterally in front of the inser- 

 tion of the antennae, the latter being long and straight. The mandibles 

 are large and are set vertically instead of horizontally, which gives the
