long as two-thirds of the width of the epiuotum. Nodes of the 

 petiole wider than long, the 2nd node twice as wide as long. Abdomen 

 much longer than wide, concave in front, the sides almost parallel. 

 The thorax is not much narrower than the head or abdomen, the whole 

 body elongate and narrow. Limits of the clypeus distinctly defined. 

 There is a small ridge on the margin of the head, extending from the 

 base of the mandibles to near the eyes, where it is depressed and ends 

 in a tooth. Dull, partly nitidulous, closely and finely reticulate- 

 punctate. In addition, the head, thorax and petiole are coarsely, 

 more or^less irregularly and longitudinally rugose. Abdomen coarselv 

 regularly and longitudinally striate, the striae almost entirely effaced 

 in the middle. Legs and scapes reticulate. The whole body, in- 

 cluding the legs and scapes, clothed with short truncate hairs. Pubes- 

 cence nearly obsolete. Black ; legs, flagellum and mandibles brown ; 

 scapes, tibiae, apices of the femora, and the tarsi brownish reddish- 

 yellow.

 (epinotum) on each side produced into a stout, sharp, bent spine, 

 beneath which it is transversely sulcate ; wings tinged with yellow, the 

 nervures pale testaceous ; the tibiae and tarsi ferruginous. The 1st

This species is unknown to me, afid it does not appear to have been 

 recorded again since Smith's time. The type requires re-examination 

 and further description as the species is in sufficiently characterised bv 

 Smith. The above description is altogether too vague, as it could 

 apply equally well to the $ $ of several other species.
