Hab. North America. ¢. Coll. Signoret (Vienna 
Museum Collection). 
As far as I know this is the only species of Bolbonota yet 
recorded from North America; the genus is omitted in 
Dr. Goding’s synopsis (Trans. Am. Ent. Soc., xix., 253) ; 
it is a very distinct species.

pedibus testaceis. 
A large species of a unicolorous testaceous colour, with the pro- 
notum tectiform, rather strongly and at the sides subrugosely 
punctured, with the dorsum continued in a straight line from apex
