recurrent i-ather than with the cubital nervure. The cubital 

 nervure of the posterior Aving originates far beyond the apex 

 of the submedian cell. 



Black ; the clypeus pale yellow ; the mandibles, the scape of the 

 antennae, the two basal joints of the flagellum, the pronotum, 

 tegulfe, scutellum, legs, the apical half of the first and second 

 abdominal segments, the apical margins of the remaining seg- 

 ments (most broadly on the fifth), the second ventral segment 

 (except the extreme base), and the apical margin of the remaining 

 segments (except the first) orange. Wings hyaline, iridescent, 

 slightly tinged with fuscous ; nervures fusco-ferruginous. 



Length 7 mm.

S . Clypeus slightly emarginate in the middle of the apical 

 margin, about twice as broad at the apex as long, minutely 

 pvmctixred and thinly clothed with silver-grey pubescence. Head 

 delicately and closely punctured, with a fine sulcus from the 

 anterior ocellus nearly reaching the base of the clypeus. Eyes 

 strongly divergent towards the vertex and less strongly towai-ds 

 the clypeus, separated at the base of the clypeus by a distance not 

 exceeding the length of the scape ; the posterior ocelli rather 

 more than half as far again from each other as from the eyes. 

 Antennfe rather shorter than the thorax and median segment 

 combined, slightly thickened towards the apex ; the second joint 

 of the flagellum twice as long as the first, and half as long again 

 as the third. Pronotum transverse and linear ; thorax as broad 

 as the head, sparsely punctured ; scutellum transverse. Median 

 segment short and rounded, the sides coarsely obliquely striated, 

 the triangular dorsal area coarsely longitvidinally striated. 

 Abdomen subopaque, very minutely and closely punctured, more 

 than half as long again as the thorax and median segment com- 

 bined, the first segment half as broad at the apex as the second 

 segment and slightly constricted, the third segment nearly as 

 long as the second ; the hyjDopygium pointed. Both recurrent 

 nervures received by the second cubital cell, separated from each 

 other by nearly two-thii-ds of the length of the cell ; the first 

 transverse cubital nervure sends out a short obscure branch into 

 the first cubital cell ; the second cubital cell is longer than the 

 third on the cubital nervure and is incompletely separated from 

 it, the second transverse cubital nervure only reaching a little 

 more than halfway to the radial nervure. The cubital nervure of 

 the posterior wing originates beyond the apex of the submedian 

 cell. 



Black ; the extreme apex of the scape of the antennae, the 

 pronotum, a rather narrow band at the a,pex of the first, second, 

 fourth, fifth, and sixth dorsal abdominal segments, veiy narrowly 

 interrupted on the first and fourth, yellow ; the tegula?, tibise^
