 wise punctured, but not so deeply as the mesonotum ; the basal joints 

 of the antenna), clypeus, palpi, mandibles, scutellum, the greater part 

 of the pronotum, a small spot on the pleura, a large mark between the 

 two posterior coxa), a ring on the basal abdominal segment, a small 

 spot on the side of the third, a ring on the hind edge of the fourth and 

 fifth, a spot on side of sixth, a smaller one on seventh, the apex and 

 the edges of all the segments beneath yellow. Labrum and tips of 

 mandibles reddish-testaceous. Legs yellow ; coxa) at base, trochanters

 the apical segment is greater, and the anal appendages arc of the same 

 colour; the belly is entirely black. The coxa) and trochanters are 

 almost entirely yellow; the four anterior femora have only a narrow 

 black line above, the posterior are only yellow on the under side ; the 

 four front tibire and tarsi are lined with black above, except at the base 

 of the former, while the apical half of posterior tibia) and the tarsi are 

 entirely black, the tarsi being thickened and much longer than in the

 shorter than in the female.
