ARTHROPODA. 



Tomicus. Platypus. 



Hylesinus. Scolytus. 



EHYNCHOPHORA. Head prolonged into a rostrum. Antennae 

 most frequently geniculate, with its basal joint [scape] received 

 into a groove [scrobe]. Vegetable-feeders. 



The rostrum varies from a mere vestige to three times the 

 length of the body. The larvae are without legs ; some spin a 

 silky cocoon in which they pass the pupa state. The Curculionidaa 

 are estimated by Jekel to include 30,000 species. It is one of 

 those groups in which many of the forms do not seem to be dif- 

 ferentiated into species.
