rugulose; posterior surface with a median sulcus; abdomen 
smooth, shining; postpetiole nodose; petiole curved, cylindrical, 
and as long as the posterior legs to near apices of femur ;

Head black; mandibles, except apices, and palpi yellow; scape 
and pedicellum yellow, flagellum piceous, ferruginous beneath ; 
thorax yellow; a median spot on scutum, a small spot before 
tubercle, a spot below each tegula, mesepimeron, a spot before, 
inclosed area of propodeum and sulcus of posterior surface black ; 
legs yellow, the posterior pair red below trochanters; abdomen 
red. Wings hyaline, iridescent; venation dark brown. Face,
