oblique slope; in the middle is a flat, smooth, shining, broavl 

 space, wliich becomes gradually and slightly wider towards 

 the apex, which is slightly incised in tlie middle. Median 

 segment thickly covered w ith depressed pale fulvous pubes- 

 cence ; reticulated; the central area large, reaching to the 

 apex, becoming slightly narrowed to the end of the basal third, 

 then more distinctly narrowed towards the apex ; the keel 

 surrounding the apical part is stout; the apex itself has a 

 sharply oblique slope and is closely reticulated all over. 

 Mesopleurae strongly punctured and thickly covered with 

 white hair. Metapleuras strongly reticulated except at the 

 base. Legs thickly covered with pale hair; the tarsal spines 

 fulvous. \^'ings deep fuscous violaceous, the base liyaline ; 

 above the second cubital cellule is slightly longer than the 

 third ; both the cellules receive the recurrent nervures sliortly 

 behind the middle. Abdomen ferruginous ; the petiole, 

 except at the apex, and the apical two segments black ; the 

 ventral keel has a slight curve and projects slightly towards 

 the apex; the middle segments are slightly punctured and 

 fringed with fulvous hair; tiie last segment is strongly punc-

 Long. 9 mm. 



In Bingham's table (p. 9) this species comes into " lA. Wings 

 dark fulvous, with a purple effulgence," and " (P. Second to 

 fifth segments red," but is very different from anything there 

 described. It differs from most of the species in the contra! 

 area of the median segment being of equal width throughout. 



Scape of antennee thickly covered with long white hair, 

 grooved beneath ; the flagellum stout, thickly covered with 

 a microscopic pile ; the third and fourth joints subequal. 

 The front and vertex punctured, thickly coveretl with silvery 

 pubescence and more sparsely with long pale hair; the eye- 

 incision deep. Clypeus shining, smooth, bare, trianguhxr. 

 Mandibles rufous in the middle, the base thickly covered with 

 long hair. Pro- and mcsonotum strongly punctured, thickly 

 covered with long blackish hair; it has two longitudinal 

 furrows, which are deeper and wider behind. Scutellum 

 coarsely rugosely punctured ; on the basal half in the centre 

 is a smooth shining space, of equal width and slightly raised 

 and projecting at the apex. Median segment reticulated, the 

 reticulations longer on the basal half, which is, especially in 

 the middle, thickly covered with pale fulvous down; its 

 central area extends to the apex of the basal portion and is of
