 as long as the 2nd, 3rd and 4th together ; the club a little longer than

 smaller relatively to the body. Club of the antenna much thicker. 

 The 9th joint of the flagellum is much smaller than the 10th, the 

 latter and the 11th considerably swollen (in the type species the 9th is 

 almost as wide as the 10th and the last two joints are only slightly 

 swollen). Otherwise like Oscaris, but of a dull brownish yellow, the 

 thorax dirty yellow. The scape is short, much shorter than in 

 minutum and floricola ; the peduncle of the 1st node shorter than in 

 floricola.'''
