their basal width. Petiole as in the 1/. Abdomen oblong-ovate,, 

 truncate at the base, the lateral angles rounded but distinct, above 

 somewhat flattened, the apex broad. The apical margins of the 

 abdominal segments pale. Wings and nervures yellowish, the stigma 

 brownish-yellow. 



$ . 5*5-6 mm. Yellowish-brown, the mandibles and antennae pale 

 ochreous, the space between the mesonotum and scutellum, the epi- 

 notum, petiole, pronotum and sides of the meso-metathorax usually 

 much paler or ochreous. Legs yellowish-brown, the articulations and 

 all the tarsi yellow. Head and thorax dull, scutellum, abdomen and 

 nodes above slightly shining. Head strongly and longitudinally 

 striate, the striae curving round behind the anterior ocellus ; the 

 sides behind the eyes obliquely striate. Sculpture of the thorax and 

 abdomen similar to that of the $ but stronger, especially on the disc 

 of the metanotum and on the epinotum, the latter having some more 

 or less longitudinal striae. 



Head subtriangular, much wider in front than behind. Eyes very 

 large, occupying more than the anterior half of the head. Ocelli 

 large, raised, the posterior ocelli more than twice as far apart from 

 each other as they are from the anterior ocellus. Mandibles short, 

 small, the masticatory margin with three acute teeth in front and two 

 smaller teeth behind. Clypeus convex, the anterior margin rounded. 

 Frontal carinae very short. Antennae filiform, finely pubescent, not 

 extending back beyond the base of the mesonotum ; the scape very 

 short, not reaching the middle of the eyes when extended laterally 

 and hardly longer than one ocellus. First joint of flagellum sub- 

 globose, very little longer than wide, the remaining joints all longer 

 than wide. Mesonotum as wide as the head, as wide as long, the 

 forks of the Mayrian furrow fairly well defined in front, the median 

 furrow obsolete. Scutellum slightly raised posteriorly, not sloping 

 downwards as in the $ , narrower behind than in the $ , its sides 

 vertical. Dorsum of the epinotum quite twice as wide at its base as at 

 its apex, about as long as the scutellum and one-third longer than the 

 declivity. Dorsum of epinotum unarmed, the teeth of the $ being 

 replaced by two subcai'inate ridges. The petiole resembles that of the 

 ^, but the node of the first joint is thicker above and less raised. 

 Abdomen elongate- ovate, narrowed apically, rounded at the base ; the 

 first segment a little wider than long and as long as the remaining 

 segments taken together. Legs long and thin. Wings hyaline, 

 nervures and stigma pale yellow. 



Cape Pi-ovince, common. (S.A.M., E.M., G.A. colls.) 



This form was originally described by Mayr as a race of P.
