This fine species, in addition to being one of the largest in the 

 genus, is remarkable for the form of its thorax. The specimen from 

 which the above desciiption has been drawn has unfortunately one 

 of its elytra undeveloped; this makes it rather doubtful as to whether 

 or not the thickened apical margin in the other is the normal state 

 of the insect, or only a malformation.
