 together. Pronotum a little narrower than elytra, somewhat broader than 

 long, slightly narrowing posteriorly, with anteriorly rounded, posteriorly 

 almost straight, or feebly incurved sides, dorsally rather flat with a 

 more or less decided longitudinal impression in middle-line and an arcuate
