 truncate, angles rounded, with strongly raised ridge separating 

 epicraniiim from forehead continuous with frontal ridge (between 

 the eyes); epicraniam depressed and sparsely punctured; eyes 

 large, transverse, separated by space less than 1 mm.; antennae

 faintly sinuate in front, incurved and produced posteriorly into 

 a distinct tooth, anterior processes just meeting, regularly narrow-

 wide (margins : disc as 3 : 7), raised near base, ratiier flat and 

 obliquely raised in front, extreme margin vertically raised and
