 equal to breadth at base including eyes ; rostrum robust, first joint 

 about or almost reaching anterior coxae ; antennae long, somewhat 

 slender ; pronotum with a broad, convex, anterior collar, the anterior 

 margins of which project slightly beyond the lateral angles of the 

 anterior lobe, which is only about half the length of the posterior 

 lobe, the lateral margins moderately laminate; the basal angles 

 broadly subrotundate ; scutellum about as long as broad, its base 

 broadly depressed, its apex acute ; corium with the lateral margin a 

 little convex, membrane passing the abdominal apex ; femora mode- 

 rately robust ; tibiae almost as long as femora, anterior femora with a 

 prominent spine near apex ; basal joint of the posterior tarsi longer
