Male: Length 7.1 mm., width 2.54 mm.; color a vivid carmine 

 red, fuscous on calli, scutellum, and bordering the commissure;

 Antennae: Segment i, length .65mm., thickness .17mm.; ii, 

 2.42 mm., greatest thickness .14 mm., tapering from middle to 

 more slender at apex ; iii, 1.6 mm., linear and slender ; iv, .60 mm. ;
