 of our eastern genera of Phylinae.'-' 



KEY TO GENERA OF TRIIJE ONCOTYLINI. 



a. Pseudarolia attached only at basal angles of claws, the free portion 

 extending parallel with them to tips ; claws short, strongly in- 

 curved (pi. X, fig. 14) ; apex of elytra in our species with six 

 pale spots. I. Macrotylus, p. 919. 



mi. Pseudarolia connate, with claws for their full length; claws broadly 

 curved (pi. X, fig. 13) ; apex of elytra without pale spots. 

 /). Beak not passing beyond hind coxa?; pseudarolia long, extending 

 beyond tip of claws; mesoscutum broadly exposed. 



II. Lopus, p. 920. 

 hl>. Beak reaching or surpassing third ventral; pseudarolia not reach- 

 ing apex of claw; extreme tips of claws sharply incurved. 



III. Megalocoleus, d. 920.
