ARTHROPOD A. 



STERNOXI. Prosternum produced in front and pointed behind. 

 Antennae filiform or serrated. Vegetable-feeders. 



The Elateridse possess a peculiar process of the prosternum 

 which, acting as a spring on the mesosternum, enables them, if 

 placed on their back, to regain their natural position. Their 

 larvae are wood- and root-feeders. To PyropJwrus belongs some 

 of the fire-flies of the Tropics. The antennas of Buprestidse are 

 marked by small pores, either diffused, or concentrated in a 

 depression on each joint.
