612 NEW FOSSORIAL BYMENOPTERA, 



$. Fusco-nigra; flagello mandibulisque fusco-testaceis, pedibus 

 testaceis; segmento dorsali secundo fusco-ferrugineo, transverse 

 ruguloso. Long. 10 mm. 



(J. Mandibles broad, bidentate at the apex, the inner tooth 

 very broad and blunt; clypeus widely emarginate, with a carina 

 from the base to the apex, closely punctured. Antennae no 

 longer than the thorax and median segment combined, the apical 

 joints strongly arcuate beneath. Head and thorax closely and 

 not very finely punctured, more finely on the vertex and median 

 segment than elsewhere; the thorax as broad as the head, the 

 anterior margin of the pronotum slightly raised. Abdomen 

 shining, somewhat flattened, very sparsely and indistinctly punc- 

 tured, fusiform; hypopygium not very small, short, and broadly 

 rounded at the apex, without an apical spine; seventh dorsal 

 segment rugose. Second abscissa of the radius longer than the 

 third, second recurrent nervure received by the third cubital cell 

 at a distance from the base equal to half the length of the second 

 transverse cubital nervure. 



£. Head large, slightly convex, nearly half as broad again 

 anteriorly as long, broadly rounded at the anterior angles, very 

 minutely punctured, with larger scattered punctures and an 

 obscure frontal sulcus. Thorax finely and sparsely punctured, 

 the pronotum nearly half as broad again as long, almost rect- 

 angular; scutellum much narrowed posteriorly. Median segment 

 opaque, as long as the greatest breadth, longer than the pronotum, 

 very narrow at the base, strongly broadened towards the apex, 

 the posterior slope oblique. Abdomen shining, sparsely punc- 

 tured, second dorsal segment coarsely transversely rugulose; with 

 two strong transverse carinse at the apex, separated by a deep 

 groove. Pygidium simple; the sixth dorsal segment finely rugose, 

 with a strong longitudinal carina, narrowly rounded at the apex, 

 shorter than the ventral plate, which is narrowly truncate at the 

 apex. Ventral segments coarsely but shallowly punctured. There 

 is a very small tubercle at the base of each antenna. 

 Hab. — Near Melbourne. 



This species is nearest to P. nitidus Sm., in the unarmed hypo- 

 pygium of the male, but in P. nitidus the hypopygium is much
