reaches back as far as the occipital margin, 1st joint of flagellum 

 nearly twice as long as wide, as long as the two following joints 

 taken together, 2nd joint not much wider than long, 3rd-10th joints 

 decidedly wider than long, terminal joint as long as the two pre- 

 ceding together. Mandibles shining, sparsely punctured, masti- 

 catory margin with about 4 or 5 small teeth, the apical tooth well 

 developed. Thoracic sutures well denned. Pronotum almost as 

 long as wide, anterior margin convex, much narrower in front 

 than behind. Mesonotum two-thirds as long as the pronotum ; 

 dorsum of epinotum flat, and as long as the declivity, the 

 latter not very oblique, its sides slightly margined. Node of petiole 

 convex from side to side in front, narrow above, vertical behind, 

 and nearly so in front, quite twice as wide as long ; ventral lamella 

 produced into a convex projection at the base. 1st abdominal seg- 

 ment a little shorter than the 2nd, wider than long, the face of the 

 1st segment in front vertical, intersegmental constriction feeble. 



? . 3"7 mm. Eyes larger than in the $ • Pronotum twice as 

 wide as long ; mesonotum two-thirds as long as the pronotum, 

 dorsum of epinotum half as long as the pronotum, the declivity less 

 oblique than in the £ , and with the brow of the declivity obtusely 

 emarginate. First and 2nd abdominal segments a trifle wider than 

 long, 2nd segment a little longer than the 1st. Wings with a 

 yellowish tinge, nervures very pale. Other characters as in the $ . 

 $ . 3'6 mm. Black, legs, antennae, and apical segment of abdomen 

 light brown. Clothed with a very sparse pale pubescence. Whole 

 body shining. Head, thorax, and petiole very shallowly and finely 

 punctured. The points of insertion of the pubescent hairs on the 

 abdomen are so shallow that they can hardly be called punctures. 

 Head sub-quadrate, excluding the clypeus, a little wider than long. 

 The clypeus projects rather far forwards and is gibbous, the anterior 

 margin obtusely angular in the middle. Mandibles truncated at the 

 apex, the apices not meeting. Eyes very large, situated within 

 the front half of the head. Ocelli small, placed on a very slightly 

 raised area. Frontal carinae feebly developed, with a deep im- 

 pressed line between them which reaches back as far as the anterior 

 ocellus. Antennae filiform or only slightly thickened towards the 

 apex ; scape twice as long as the 1st joint of the flagellum, but not 

 longer than the distance separating the two posterior ocelli. The 

 antennae reach back as far as the brow of the epinotum. Pro- 

 notum short and exposed ; mesonotum about one-third wider than 

 long, anterior margin round, parapsidal furrows well defined, 

 separated by a deep suture from the scutellum. The latter is
