Tlic species arc comparatively of great bulk in regard to the other 

 Ikachelytra ; and they may be usually distinguished by having the 

 head (which is frequently as large as. or larger than, the thorax) 

 cxserted, and the labrum deeply bilobed. The indigenous species 

 may be thus divided into genera, chiefly as proposed by Dr. liCach.
