transversely, and as long as wide. The scutellum is nearly one and a 

 half times wider than long, a little more than one-third the length of 

 the mesonotum, and is a little higher than the latter. Dorsum of 

 epinotum very short — much shorter than the declivity, which is 

 vertical. The epinotal spines are shorter and broader than in the ^ > 

 almost triangular, and very little longer than their basal width. A 

 rounded, lobe-like expansion covers the stigmata on each side, and 

 projects beyond the lateral profile of the thorax. Wings dark brown, 

 the nervures and stigma piceous. Otherwise like the $ . 



<$ . 13 - 5 mm. Black, flagellum and tarsi dark brown. Pilosity 

 moi*e abundant, but much finer than in the $ , the hairs being 

 thinner, especially on the abdomen, whei*e they are also more oblique. 

 Flagellum densely and very finely pubescent. Thorax and upper 

 surface of the nodes with a whitish pubescence ; sparse and oblique on 

 the thorax ; dense, erect, and longer on the dorsum of the epinotum 

 and anterior face of the 1st node (more easily seen when looked at 

 from the side). Head very coarsely rugoso-striate, transversely so on 

 the posterior half, more or less longitudinally on the anterior half, the 

 space between the rugae shining. Thorax coarsely and longitudinally 

 rugoso-striate, the striae interrupted, stronger on the scutellum and 

 posterior half of the mesonotum. Epinotum very coarsely reticulate- 

 rugose, the declivity with some transverse striae. Thorax rather dull, 

 declivity of epinotum smooth and shining. Nodes of petiole micro- 

 scopically alutaceous, also longitudinally striate, the 1st node some- 

 what coarsely so, the 2nd node much more closely and finely striate, 

 its median area smooth. Abdomen, except for a narrow median area 

 on each segment, microscopically alutaceous and dull. Head longer 

 than wide, the posterior margin concave. The eyes large, placed some- 

 what obliquely, occupying quite half the sides of the head. Ocelli 

 fairly large, slightly raised. Clypeus less convex than in the £ or ? . 

 Mandibles oblong, edentate, obliquely truncate apically. Scape short, 

 hardly longer than the distance between the two posterior ocelli ; 1st 

 joint of flagellum as wide as long, about one-third the length of the 

 scape ; 2nd joint as long as, or a little longer than, the scape ; all the 

 remaining joints at least twice as long as wide. Thorax similar to 

 that of the ? , but narrower, the mesonotum nearly one-quarter longer 

 than wide. Dorsum of epinotum longer than in the ? , at the base 

 nearly three times wider than long, shorter than the declivity, bluntly 

 angulate on each side at the apex ; the declivity vertical. Petiole very 

 long, as long as the abdomen, and nearly as long as the thorax ; the 

 peduncle of the 1st joint is as long as the node, the latter one-third 

 longer than wide, and flattened. Second node oblong, rounded
