Supplementary to Riley's description: 



Abdomen from base of second segment longer than head and thorax 

 combined. First joint of club broader than long. Pedicel plus ring-

 groove brownish.

 twice as long as broad. Scape, exclusive of base, one-third as broad

 shagi'eened and also very sparsely and finely rugulose ; metanotum somewhat 

 coai'sely rugulose and without median furrow, but with a rather faint median, 

 longitudinal carina ; raesoscutellum rather rounded at apex, not sharply pointed ; 

 axillae and parapsidal sutures nearly meeting, pronotal spots evident but
