The sculpture of the antenne brings this dubious little genus within the limits of the 
Piezocerine ; but in general form and in the proportions of the antennal joints it more 
nearly resembles the Graciliine. Marked peculiarities are the absence of hairs from 
both body and limbs, and the very close, elegant, reticulated sculpture, 7. ¢. deep 
punctures with net-like interstices, of the whole body.
