108:3 



Tribe VI. ONCIDERINI. 



Front coxal cavities angulated on the outer side 

 and closed behind ; anteunre longer than body in 

 male, as long as body in female, the scape stout, \ 

 without cicatrix ; legs rather stout, equal; claws 

 slightly divergent. One genus of the tribe is rep- 

 resented in New York, Pennsylvania, Louisiana, 

 Texas and probably southern Indiana by the "hick- 

 ory girdler, " Oncideres ciiigulaia Say, length 14- 

 17 mm., smoky or reddish-brown to clay-yellow in 

 hue, with the pubescence usually forming a broad 

 median band on elytra, thorax with or without a 

 spine on sides, the disk usually with three small 

 black facets. The female beetle deposits her eggs in 

 twigs of trees and then cuts a girdle about the twig nSe - (~ AfterRile y 

 below the eggs. (Fig. 467.) The twig dies and is broken off by the 

 wind, falling to the ground where the larva 1 mature. The beetle oc- 

 curs in August and September ami not only girdles the young twigs 

 of hickory, but also those of pear, apple, plum, elm, linden, and 

 other trees. 



Tribe VII. HIProrSINI. 



Body very slender ; front long and inflexed so that the mouth is 

 near the prosternum ; palpi not slender, the last joint almost conical 

 and pointed; eyes coarsely granulated; front coxaa annulated; legs 

 rather short, equal; tarsi as long as the tibiae, first joint of hind 

 pair slightly elongated, last joint rather long, claws divergent. One 

 of the four genera is represented in the State.
