Male. — Black: Labrum, mandibles except apices, clypeus, scape 

 below, very broad anterior orbits abbreviated above, space between 

 insertions of antennae prolonged upward, spot below anterior ocellus, 

 line on posterior border of pronotum, tubercles, sides of prothorax 

 in part, spot on tegulae, small lateral spots on scutum at base of 

 anterior wing, broad fasciae on tergites 1-6, first narrowly inter- 

 rupted medially, second, third, and fourth biemarginate dorsally and 

 sinuate laterally on anterior margin and on posterior margin acutely 

 emarginate medially, fifth and sixth but slightly emarginate or 

 sinuate, small spot on apex of seventh, lateral spots on sternites 2-5, 

 the greater part of the femora distally, tibiae except spot below on 

 anterior pair, and tarsi, yellow. 



The middle femora are dentate and the antennae are spinose on the 

 posterior border of segments 5-9. The second sternite bears a 

 prominent hooked process and the sixth a somewhat short, broad, 

 roundly pointed process whose ventral surface distally is slightly 

 concave, presenting a spoon-shaped appearance. The spot before the 

 anterior ocellus is wanting on some specimens, and the line on the 

 pronotum consists of spots. On some specimens the scutellum bears 

 small lateral spots and lateral spots may occur on the sixth sternite. 



Female. — Black: Labrum, mandibles except apices, clypeus, scape 

 below, broad anterior orbits shortened above, space between antennae, 

 line on posterior border of pronotum tubercles, sides of the prothorax 

 in part, spot on tegulae, short lateral line on scutum at base of wings, 

 lateral spots on scutellum, fasciae on tergites 1-5, first interrupted, 

 second, third, and fourth biemarginate dorsally and somewhat sinuate
