Not being able to come at the trophi [Instrumenta cibaria Fabr.) 

 of this insect, I cannot clearly ascertain whether it belongs to 

 Trox or Meloloiitha. Its habit, stature, and closed mouth are 

 nearly those of the former genus ; but the first joint of the an- 

 tennae is not hairy as in that, its abdomen not vaulted and flat, 

 and the anterior pair of tibiae are not without teeth.
