with somewhat dilated tibia; abdomen with a few larger 

 punctures, terminal joint rounded at tip, entire, ciliated 

 and attaining the tip of the geminate joints of the pedi- 

 palpi. 



Length three tenths, breadth one half an inch. 



This curious animal occurs in the Richmond Mu- 

 seum. Mr. J. Warrell, the proprietor of that interesting 

 establishment, supposes it to be American, but whe-

 lated, but the corresponding tarsi are accidentally want- 

 ing in this specimen.
