This description is made after a single female individual, 

 but I have little doubt that the insect belongs to the numer- 

 ous tribe to which I have referred it, in which it ought perhaps 

 to be placed near Eccoptogenius Chaud. I am however, not 

 sure whether the shape of its liguladoes not entitle it to a place 

 amongst the Anchonoderidae. I may add to the above de- 

 scription that the accessory stria of the elytra is present, but 

 that the puncture usually found upon the 3rd interstice is 

 wanting. The general appearance of the insect presents no- 

 thing whatever particular, however, upon further inspection 

 the deeply notched labrum and the strong porrected mandibles 

 are very striking. The labrum appears to me of extraordinary 

 construction: the mentum is large and of semicircular shape, 

 deeply emarginated, which renders the lobes heavy, rounded 

 outside and pointed at the tip. In the bottom of this emar- 

 gination stands a pointed, spinelike tooth, as long as the lobes. 

 This tooth is deeply excavated or grooved and is clearly seen 

 to be to its full length soldered together with the basal part 

 of the ligula; probably the entire mentum is in this manner 

 connected with the adjoining part of the ligula, but in the 

 other parts it is not so clearly observable as in the tooth, and
