 form being rarely transverse. The male has longer antennse than the female, and 

 their base is a little thickened.

 anterior acetabula still more prolonged externally than the preceding group, and the 

 eyes are simply transverse, not embracing the antennse, which are situated at the 

 base of the mandibles and in front of the eyes ; the inner lobe of the maxillae is 

 sometimes obsolete.
