ZOYPHIUM NIGRUM new species. 

 Female. Length 6 mm. C'lypeus transverse, convex in the middle, the apical' 

 margin with two teeth on each side ; clypeus and the lower half of face clothed with 

 silver pubescence ; ocelli nearly twice as far from eyes as the diameter of one ; 

 antennae clavate. the fourth and following joints broader than long ; apical joint 

 large, obliquely truncated and excavated, not nearly so massive as in Z. emargina-' 

 turn. Prothorax rather produced in the centre where it is triangularly emarginate ; 

 thorax and scutellum finely punctured ; median segment finely diagonally striated,, 

 with a short longitudinal carina which ends in a shining circular depression, short 

 white pubescence at the sides of segment. Abdomen finely punctured, clothed with 

 thin white pubescence, the apical segment triangular, more coarsely punctured 

 and covered with short grey hair ; second submarginal very narrow on the radial 

 nervure, receiving the second recurrent nervure past the middle, the first recurrent 

 nervure is received at about the same distance from the first transverso-cubital 

 nervure as the second recurrent is to the second transverso-cubital nervure. 



Black, base of mandibles, part of tubercles, tibial spines, second, third, and 

 fourth tarsal joints sordid white ; tegulae, tibiae, first and fifth tarsal joints fuscous ;

 equal "distance from the apex of the first submarginal cell. 



Black, base of mandibles, the whole of the clypeus, underside of scape, 

 tubercles, apex of anterior femora, anterior tibiae, the spurs, and the tarsal joints
