lateral angles 3 ; cervical grooves shallow, converging and then diverging 
widely, not attaining the posterior border; lateral grooves marked by 
a more or less salient ridge attaining the postero-lateral border; many 
coarse, uniformly distributed punctations, especially between the cervical 
grooves posteriorly; no hairs. Capitulum : Base somewhat triangular 
dorsally, appearing longer than broad, dorsal ridge straight, with minute
