Antenna geniculated, 12-jointed, moderate, slightly gracile ; the scape clavate, 

 reaching to the eyes ; the two basal joints of the funiculus rather long and 

 obconic, the remainder short, subnodose, scarcely increasing in breadth 

 towards the apex ; club oblong-ovate, acuminate. Rostrum rather short 

 and a little thickened, rounded, carinated, the apex slightly incrassated : ei/es 

 lateral, rounded, depressed : thorax somewhat transverse, with a longitudinal 

 carina; truncate anteriorly and posteriorly, with the sides rounded: scutellum

 be known from Alophus : from Merionus it differs in having the 

 rostrum and thorax carinated, and the body ovate.
