Lateral carinae of the pronotum deflected outwardly behind the 

 eyes, not directed toward the hind edge 8 



2. Median carina of the front normally narrowly forked below the 



apex of the head, the branches usually obscure where they pass 

 over the apex; lateral carinae of the pronotum sometimes 

 abbreviated at about the middle of the pronotal disk; face with 



a pale band crossing the base of the clypeus Pissonotus, p. 48 



Median carina of the front running to the apex of the head; face 

 without a transverse pale band on the base of the clypeus 3 



3. Front narrow or a very little wider below ; the sides rectilinear 4 

 ' Front broader below or oblong 5 



4. Vertex produced for nearly or quite one-half its length before the 



eyes ; lateral carinae of the pronotum rectilinear Stenocranus, p. 46 

 Vertex scarcely surpassing the eyes ; lateral carinae of the pro- 

 notum bowed outward on the disk Stobaera, p. 51 



5. Front oblong, a little wider above the antennae; apex of the head 



rounded, the carinae nearly obsolete there Kelisia, p. 46

 obsolete and not continued over to the front; front elliptical, 

 its base acute, the apex truncated, the median carina obsolete 



or nearly so Megamelanus, p. 47 



Form sometimes slender ; vertex less produced, truncated at apex, 

 the lateral carinae of the front continued over on to the vertex 7 



7. Front ovate, its sides much arcuated below, nearly rectilinear 



above to the narrow base ; form slender Prokelisia, p. 47 



Front less widened to its apex ; form broader ovate 



Megamelus, p. 48
