Eab. Panama, Bugaba (Champion). 



Antennae as long as the body ; the third joint straight, about one fourth longer than 

 the next. Face aciculated ; clypeus almost transverse at the apex, not projecting much, 

 a longish depression above it on either side ; vertex depressed above the antennas, the 

 ocelli placed at the end of the depression and slightly raised. Thorax flat above ; the 

 scutellum scarcely raised, its sides at the apex depressed and distinctly separated ; a 

 broad and deep oblique furrow on the mesopleura. Petiole uniformly raised in the 

 centre ; the edge of the raised part with a distinct border ; the side depressed below it 

 and with a broad furrow. Abdomen with a triangular field (bounded by a deep furrow) 

 in the centre, and an oblique furrow on either side, of the second segment ; a deep 

 furrow along the sides ; apical segment with longish hair. Legs densely covered with 

 greyish hair; apical joint of the trochanters piceous; four anterior knees testaceous; 

 four anterior tarsi whitish, except the apical joint ; spurs testaceous. The cloud on 

 the fore wings extends across from the first cubital cellule, becoming narrower as the 

 opposite side of the wing is reached ; the apical cloud commences a little beyond the 

 second transverse cubital nervure; the hind wings are smoky, with a fainter band 

 before the apex. 



The group of B. distinguendus. 



Second abdominal segment not furrowed at the sides, and without a keel down the 

 centre ; suturiform articulation straight or but slightly waved. 



Differs from the group of B.frustratus only in the second segment not being furrowed 

 laterally, and in the suturiform articulation not being so acutely bent.

6 (5) . Ovipositor scarcely longer than the abdomen ; wings uniformly 



fuscous ; sides of the abdomen broadly white heterodoxus. 



7 (2). Face not roughly punctured or reticulated; abdomen for the
