the type of the species, but nevertheless fairly shining between the 

 reticulations. The posterior margin of the mesonotum lacks the little 

 median excision which is present in the type. Meso- and epinotal 

 spines equal in length, but the latter are thinner and more acute than 

 the former, which are slightly curved upwards at the apex. Otherwise 

 like the type of the species, 



$ . 6*1 mm. (hitherto undesci'ibed). Colour as in the £ , but the 

 scutellum, epinotum, and petiole more or less dark red or reddish- 

 brown. Sculpture like that of the ^ , but the superimposed reticula- 

 tions on the base of the. abdomen are stronger than in the $ , and the 

 meshes more elongate. Eyes not much larger than in the ^ , the 

 ocelli small and depressed. Pronotum very little exposed above in 

 the middle, more exposed at the sides, the shoulders subangular. 

 Mesonotum moderately convex in front, rather flat behind, one-third 

 wider across the tegulae than long. Scutellum subtriangular, the 

 sides feebly convex, narrowly rounded behind, projecting somewhat 

 over the very short metanotum. Dorsum of epinotum obsolete 

 between the teeth. The latter are triangular, acute, as long as wide 

 at the base ; the declivity vertical, smooth and shining. Nodes as in 

 the $ . Abdomen emarginate at the base, ovoid, longer than wide. 

 Wings rather long (the front wing 6 mm. long), tinged with yellow, 

 the nervures and stigma brownish-yellow. Otherwise like the $ . 



$ . 5 - 3 mm. (hitherto undescribed). Black, the articulations of 

 the legs reddish, the tarsi, antennae and mandibles pale dirty yellow. 

 Head, thorax and nodes slightly shining, abdomen very shining. 

 Pilosity thinner, less abundant and iess woolly than in the 9 • Head 

 and thorax very coarsely reticulate-rugose, the rugae becoming more 

 longitudinal on the posterior third of the mesonotum ; epinotum 

 longitudinally rugose above, the declivity transversely striate, the sides 

 of the thorax and epinotum more or less rugoso-striate. Nodes finely 

 striate longitudinally, abdomen smooth except at the extreme base 

 round the articulation with the petiole, where it is fan-wise striate. 

 Seen from the side, the head is almost angular above at the ocellar 

 region, the anterior and posterior surfaces falling steeply downwards 

 from that point. The head is wider than long, widest across the eyes, 

 the outline behind the eyes almost semicircular. Eyes very large and 

 hemispherical, occupying the anterior half of the sides of the head ; 

 the ocelli large and prominent. Mandibles small, elongate, with an 

 acute apical tooth and minutely denticulate behind. Scapes short, half 

 as long as the distance between their sockets and the anterior ocellus ; 

 1st joint of flagellum slightly longer than wide, the 3rd and following 

 joints all somewhat swollen and thicker at their basal third. Meso-
