This section contains two species only^ botli of wbicb are rare, one 

 excessively so ; they occur almost exclusively in rotten ^\'Ood, and are 

 easily distinguisbed by their very small eyes.

broad Q- LONGICOENIS, Kr. 



2. Size small; antennae short, witli joints 7-10 strongly 



transverse Q- miceops, Grav.
