With this group begins the series of those in which the scutellum is 
more transversely quadrate, the emargination of the elytra for its 
reception broader, widely open anteriorly, marginate, combined with a 
head and rostrum together more elongate and arcuate, much longer than 
the thorax in both sexes, the rostrum itself being at least as long as the 
head.
