laminate, prolonged backwards and curved downwards at their ex- 

 tremity. Petiole of the usual shape, its two joints not narrowed above 

 to form transverse ridges, the 1st being cylindrical in front, thickened 

 behind. The 2nd nodiform, rounded above, about as long as wide, 

 and hardly wider than the 1st node. Black, tips of the mandibles 

 and the antennae reddish yellow, tarsi and genital armature blackish 

 brown. Pubescence almost absent ; pilosity sparse, except at the apex 

 and below the abdomen, where it is longer and more abundant. Head, 

 including the clypeus and frontal area, thorax and petiole densely 

 punctate-rugose, dull ; abdomen very finely rugulose, fairly shining. 

 Wings nearly hyaline or barely tinged with yellow ; nervures and 

 stigma pale yellow."

^ . 2'8-3 - 4 mm. Yellowish brown ; disc of pro-mesonotum and legs 

 paler ; abdomen black, with a submetallic gloss. Abdomen with a few 

 thick, pale hairs. Dull. Head very finely and longitudinally reticu- 

 late-striate. Thorax closely and finely granulate (reticulate-punctate). 

 Head nearly quadrate, a little longer than wide, and a little wider in 

 front than behind. Scape short, not reaching the posterior margin of 

 the head. Pronotum almost as wide as the head posteriorly. Pro- 

 mesonotal suture faintly indicated, but more clearly than in Junodi. 

 Dorsum of epinotum half as long as the pi - o-mesonotum ; the declivity 

 sub-vertical, the brow rounded. The epinotum is barely excavated, 

 and the profile of its dorsum is only moderately convex, or almost 

 flat. First node of petiole wedge-shaped; convex transversely in 

 front, behind and above ; one-qttarter higher than the 2nd node. 

 The latter is as wide as the 1st ; widest in front. 



$ (hitherto undescribed). 4 - 6 mm. Black; mandibles, antennae, 

 and legs yellowish brown. Head and abdomen with a scanty, short 

 and decumbent pubescence ; the nodes and abdomen with also a few 

 pale, pilose hairs. Head, pro- and mesonotum and scutelluni longi- 

 tudinally reticulate- striate. Nodes of petiole and sides of epinotum 

 reticulate-punctate ; the epinotum above transversely striate. Abdo- 

 men very finely and rather obliquely striate. The pronotum is slightly 

 exposed in the middle, much more at the shoulders. The epinotum is 

 widest in frontfacross the level of the stigmatic orifices, which are 

 somewhat angularly prominent. The dorsum of the epinotum is flat 

 at the extreme base, beyond which it is shallowly excavated, the ex- 

 cavation being continued over the declivity and forming moderately 

 distinct lateral bosses orniargins on each side. First node of petiole
