 13-jointed, brownish luteous, slightly duskier at the tips of the joints, 

 very minutely pilose. Pronotum smooth, a little depressed in the 

 middle, especially at the sides, with a slight median impressed line; 

 it is a little longer than broad, with the sides very nearly parallel, 

 but diverging slightly; posterior edge a little convex, the posterior 

 angles pretty distinct. Tegmina nearly twice as long as the prono-

 dark castaneous at the tip. They are rather simple, flattened cylin- 

 drical, directed toward each other at the extreme base so as to 

 become attinient, beyond straight, curving inward at the pointed 

 tip: withiu they have a basal triangular expansion, beyond which the 

 inner edge is straight to the curved tip, and finely crenulato-dentic- 

 ulate. Length of body. 8.75 mm.; of antennas, 6 mm.; of tegmina
