the basal Joint of the bind tarsi, bright yellow; flagellum of antennae from the pedicle brown, black above; 

 wings hyaline, nervures black. The yellow mark on the face broad above, not extending to the base of the 

 antennae, shortly obhquely narrowed; the central mark on the face small, Square. 



Head closely punctured, punctures on the face and clypeus more widely separated than they are on the 

 front and Vertex. The lower half of the front is raised in the centre, the raised part extending between the 

 antennae, widened below, bordered by fine keels and bearing 2 longitudinal Striae. Mesonotum closely and 

 rather strongly punctured, scutellum is as strongly, but not so closely punctured. Metanotal area stoutly, 

 irregularly, closely reticulated; it is bordered behind by a keel; metapleura more strongly and distinctly punctured 

 than the mesopleurae. Abdomen shining, sparsely finely punctured. L. 5 mm. 



Is not unlike P. curvicarinata Cam., which species may been known by the i. recurrent nervure being 

 received in the apex of the i. cubital ceUule, it is also larger; labrum and mandibles are yellow, not black, the 

 lateral yellow marks on the sides of the face are longer, project more above and instead of being gradually 

 narrowed to a point above, have the upper part narrowed, it being only half the width above of its base; the 

 yellow, too, is paler, not so orange-tinted. In P. curvicarinata the 3'ellow mark on the face is twice longer than 

 Wide, not Square.

?. Black, a large mark on the clypeus, its lower half obliquely narrowed to a point, a large mark on 

 the lower half of the inner orbits, obliquely narrowed above and below, a mark, broader than long and of 

 equal width throughout, between the antennae, yellow; the sides of the clypeus broadly below, mandibles, the 

 scape, under side of flagellum, a line on the pronotum, tegulae, tubercles, the base and sides of first abdominal 

 Segment, the sides of the others more or less and the greater part of the ventral surface, rufous. Wings hyaline, 

 the apex in front slightly smoky. Legs rufous. L. 8 mm. 



Metanotal area with some stout, irregulär, curved Striae. Front and vertex closely, regularly, and 

 strongly punctured ; antennal area large, raised, rugose and bounded laterally by curved keels. Clypeus strongly, 

 but not so closely, punctured as the front; the cheeks almost smooth. Labrum rufous; the top broadly, roundly 

 raised; the apex depressed, obliquely narrowed, aciculated and with a few scattered punctures. Mandibles black 

 and rufous. Mesonotum closely, strongly and distinctly punctured; the scutellum as strongly, but not so closely 

 punctured. Pleurae and breast coarsely rugose and thickly covered with white pubescence; the metanotum more 

 closely rugose. Postscutellum opaque, very sparsely punctured. Abdomen smooth, the apices of the segments 

 with a narrow band of white pubescence. Both the recurrent nervures are interstitial. The male wants the red 

 lateral marks on the clypeus. Both sexes vary in the amount of the rufous colour which they bear; the yellow 

 line on the pronotum may be tinged more or less with rufotis. The malar space obsolete.

?. Black, anterior */^ of clypeus, posterior margin of pronotum broadly, a spot beneath the tegulae, 

 basal half of scutellum and the apices of all the femora bright yeUow, the tibiae and tarsi of all the legs, the 

 apical margins and sides broadly of the basal 2 and the disks of the rcmaining abdominal segments red. Wings
