Head with a central furrow and a more or less distinct trans- 

 verse impression behind the eyes, separated from the rostrum on 

 each side by a sinuate transverse furrow in front of tiie eves; the 

 latter convex, lateral, prominent, very^ short (ivate and rather 

 acuminate interiorly, liostrum broader than the forehead at its 

 base, with a variable central furrow, deeply emarginate at the 

 apex, the epistome bare, shiny and forming a sharp acute angle 

 behind ; scrobes dorsal, very deep in front, but shallower Jiear the 

 eyes and curving inwards about the middle; the gen ae more or 

 less wrinkled and with a strongly curved furrow which extends to 

 the lower surface ; mandibles obtuse, prominent and with a 

 strongly marked scar. Anteume inserted at or rather before the 

 middle of the rostrum ; the scape exceeding the hind margin of 

 the eye, usually dilated and more or less strongly curved ; the 

 funicle 7-jointed, joints 1, 2 and 7 longer than the others, the club 

 4-iointed. Prothorax usually with strong transverse plications 

 and a more or less distinct central furrow, the anterior margin 

 truncate laterally (except in salcuoUis), the base either bisinuate 

 or subtruncate, tlie gular margin shallowly sinuate. ScvteUum 

 variable, usually well developed, but sometimes invisible and occa- 

 sionally enclosed in front by the sutural margin of the elytra. 

 Elytra not soldered together, with or without a distinct humeral 

 angle, the base slightly covering the basal margin of the prothoiax, 

 the posterior declivity steep, the lateral margin sinuate above the 

 posterior coxse, the striae or sulci punctate and 10 in number ; 

 rudimentary wings present. Sttrnma with the front coxae nearer 

 the anterior margin of the prosternum ; the mesosteruum with, 

 the e|)imeron much smaller than the episternum, the intercoxal 

 jirocess dilated at its apex ; the metasternum is either equal to, 

 slightly shorter than or slightly longer than the median coxiu, the 

 episternum is extremely^ narrow and usually quite concealed, with 

 the exception of the enlarged anterior portion, the hind coxae 

 touch the ely^tral margin. Venter with the intercoxal piece augu- 

 lated and not broader than the hind coxie : segments 2, 3 and 4
