5 S P. CAMERON. HYMENOPTERA I. 



black, its apex transverse. Basai half of mandibles yellow on the innerside. Flagellum of an- 

 tennae fulvous below. Thorax closely and strongly punctured, as is also the abdomen. Pygi- 

 dium narrowed roundly at the base and apex, slightly wider at the base than at the apex; 

 the base with some irregular longitudinal striae, the middle irregularly transversely striated, 

 the apex finely rugose.

StizUS Latr. 



1. Stisus papuanus sp. nov. 

 Lake Jamîir, August. 



Latéral angles of metanotum distinctly incised, the upper and lower sides of the inci- 

 sion straight, oblique, forming a sharp angle on the innerside, the upper side longer than 

 the lower. Black, shining, the head and thorax thickly covered with a whitish pubescence; 

 the clypeus, except for a large black mark in the centre, the mark wider than long, the top 

 transverse, the sides and apex rounded, face, palpi, labrum, a narrow line on the apex of 

 the pronotum, tubercles, base of tegulae, scutellar keels, a small mark, longer than broad, 

 on the base of scutellum at the sides, a broad line on the post-scutellum, the latéral angles 

 of the metanotum, a broad band, narrowed in the middle on the apex of the ist abdominal 

 segment, a similar, but narrower one on the apex of the 2 nd and narrower lines on the apices 

 of the 3><L 4H1 and 5A segments (that on the y& being narrower, less distinct, than on the 

 others), pale yellow. The 4 anterior tibiae in front, the fore femora in front, the apex of the 

 middle femora, and a mark on the outerside of the hind tibiae at the base, yellow. Wings 

 hyaline, the nervures and stigma black ; the 2 nd cubital cellule not appendiculated, but with 

 the nervures close to each other. cf. 



Length 7 mm, 



Eyes distinctly converging below, separated there by slightly less than the length of 

 the antennal scape. Head and thorax sparsely, indistinctly punctured. The 2 keels on the 

 apical half of the metanotum are stout, narrowed and slightly roundly diverging above. 



The présence of an incision on the sides of the metanotum and the présence of a 

 yellow fascia an the 3 rd abdominal segment, would, in Handlirsch's table, Sitzungsber. d. 

 kaiserl. Akad. d. Wissensch. in Wien, CI. Abth. I, 1892, p. 185, bring this species close to 

 5. signatus Hand. from Australia, with which species it cannot be confounded. In size and 

 gênerai colouration it agrées with S. proximus and 5. socius; but thèse species hâve not the 

 sides of the metanotum excised.
