subvertical declivity, the two faces of equal length. Scale of petiole 

 subnodiform, the anterior face convex from above to below, or vertical 

 below and oblique above, the oblique area almost dorsal in position, 

 semicircular and twice as wide as long ; the posterior face vertical 

 and almost flat. The petiole from below to the apex of the node is as 

 high as long. Thorax highest at the brow of the declivity ; convexity 

 of thorax, L. = 4 H. 



$ minor, 11-5— 12*5 mm. Head two-thirds longer than wide, 

 almost parallel-sided, the sides feebly convex only behind the eyes, 

 the posterior margin almost straight, the posterior angles narrowly 

 rounded. Eyes more convex than in the 2J., placed a little in front of 

 the posterior third of the sides. The scapes extend beyond the hind 

 margin by about two-fifths of their length. Clypeus not lobed, the 

 anterior margin convex and only slightly produced. Thorax narrower 

 than in the 2i, the declivity less oblique and joining the dorsum in a 

 widely rounded angle. The apical half of the dorsum strongly com- 

 pressed, cristate and almost linear lengthwise. Node of petiole a little 

 longer. There is a pale ochreous spot on each side of the head just 

 behind the anterior angles. Otherwise like the 2|. 



$, (hitherto undescribed), 16-5 mm. Head a little less than one-third 

 longer than wide, widest behind the eyes, the posterior margin straight 

 and one-third wider than the anterior, the sides fairly straight, the 

 posterior angles nearly rectangular. Sculpture of the head stronger 

 than in the 2J., also shallowly punctured, the punctures pubescent. 

 Clypeus very feebly carinate, the anterior margin of the lobe slightly 

 convex. Mandibles shining, punctured as in the 2J_. The scapes 

 extend beyond the hind margin by as much as the length of the 1st 

 joint of the flagellum. Ocelli small. Eyes convex, placed a little 

 behind the middle. Thorax finely and very closely reticulate- 

 punctate, dull ; the metanotum smooth and shining. Scale sub- 

 cuneiform, the two faces equally convex, the dorsal edge straight, 

 fairly trenchant, feebly emarginate in the middle. Abdomen longer 

 than wide. Dealated. Otherwise like the 2J.. 



c?, (hitherto undescribed), 10-2 mm. Black, dull. Head and thorax 

 strongly reticulate - punctate, abdomen transversely reticulate- 

 rugulose, much more coarsely so than in the 2 or 2[. Head, sides 

 and front of the mesonotum, legs and abdomen with a sparse but 

 fairly long decumbent pubescence, wanting elsewhere. Pilosity long, 

 absent from the mesonotum and scutellum, sparse on the head, fairly 

 plentiful on the abdomen, very long and abundant on the sides of the 

 epinotum and on the petiole. Head one-third longer than wide,
