Genus CCCV. — Dorytomus, Germar. 



Antenna geniculated, 12-jointed, inserted towards the apex of the rostrum j 

 slender, long ; funiculus 7-jointed, its basal joint very long, slender, clavate ; 

 second elongate, but shorter than the first, obconic ; the remainder short, sub- 

 nodose ; club oblong-ovate. Rostrum very long, slender, curved, the apex 

 slightly incrassated : eyes depressed : thorax short, transverse, a little con- 

 stricted anteriorly, the sides rounded: scutellum small: elytra elongate, 

 rounded at the apex, simple : legs moderate, anterior sometimes elongate j 

 femora slightly incrassated, dentate beneath; tibia; straight, the anterior a 

 little curved towards the apex, and armed within with a minute hook. 



The Dorytomi (especially the typical species) differ from the in- 

 sects of the two foregoing genera by having the anterior legs — which 

 approximate at the base — considerably elongated, the femora but 

 slightly incrassated, and dentate, the thorax coarctate anteriorly : — 

 the species usually frequent trees of the willow and poplar kind, 

 and occur during the summer.
