Figures 18, 28, 29, 30, 49-51, 83, 95, 107. 



(^. Head transverse ; the occiput immargined ; temples narrow ; eyes 

 large, distant from one another above by little more than the distance 

 between the hind ocelli, with a triangular emargination, the apex of 

 which is obtuse ; ocelli in an equilateral triangle, crowded forward, 

 distant from the occiput, the hind pair almost touching the eyes ; front 

 comparatively flat, with neither tubercles nor a ridge ; clypeus moder- 

 ately convex, its anterior edge deeply emarginate ; mandible acute, the 

 inner edge with two preapical teeth, the more apical one fair sized ; 

 labial palpus with four segments, the apical segment very short ; 

 maxillary palpus reduced to a single segment represented by a mere 

 tubercle. Antenna longer than head and thorax united, gradually 

 widened into an oval club, which is convex on all sides ; the scape sub- 

 globular ; the pedicel short, segments 3 to 5 elongate, cylindrical, 6 

 and 7 gradually evenly widened, longer than broad ; segments 8 to 12 

 fused, but the divisions distinguishable. 



Humeri marked by a ridge ; parapsidal furrows absent ; tegula 

 elongate, reaching over the base of the scutellum, the apex obtuse, the 

 outer margin weakly and broadly emarginate mesally ; scutellum con- 

 vex; postscutellum prominent, bifid at apex; propodeal angles hori- 

 zontally subulate, forming acute angles. 



Forewing not plaited ; lacking R- ; m-cu arising from M^. Anterior 

 trochanter unarmed ; all femora and tibiae with regular surfaces, some 

 of them slightly flattened and with a weak ridge beneath, ])ut devoid 

 of tubercles and carinae ; anterior tibial spur slender, slightly curved, 

 the tip acuminate and bent outward ; middle tibia witli two stout spurs ; 

 longer spur of the posterior tibia pectinate at apex (see fig. 95) ; tarsal 

 claws each with a minute tooth on the middle of the inner margin. 



Abdomen sessile, slender, broadest at base, the first segment from 

 a dorsal view somewhat concave anteriorly, the second to fifth dorsal 

 segments somewhat contracted at base, the last bidentate and deeply 

 notched at apex ; second and third ventral segments each witli a process, 

 that of the second acute, of the third larger and transverse ; last ventral 

 segment with the apical margin weakly concave.
