which the proportion of the third and fourth joints is reversed. 

 The interval between the eyes is considerably less than the width 

 of either eye as seen from above. The apical joint of the antennse 

 is considerably longer than the tenth. The sexual distinctions 

 seem very slight ; in the male the intercoxal process of the hind 

 body is conspicuously elevated. The metasternum is extremely 

 tumid, and is in many examples considerably darker in colour 

 than the hind-body.

I do not find any character decisively indicating tlie sex of my 

 example of this fine species, which probably points to its being a 

 female, as it is probable that the anterior tibi;e of tlie male are 

 toothed within. The extremely fine strije of the elytra, their
