strongly depressed transverse line near middle, base of the seg- 

 ments more sparsely and finely punctured. Epipygium narrowly 

 produced and rounded at apex, produced into acute angles at 

 sides before apex; recurved spine of hypopygium only extending 

 a little beyond epipygium. Entirely black. Wings hyaline, 

 nervures fuscous. Length 17 mm. 



Q. Head subquadrate, very slightly rounded at posterior angles. 

 The whole inject very deeply and rather sparsely punctured. 

 Pronotum broader than long, slightly narrowed anteriorly. 

 Median segment flattened, widened from base and almost verti- 

 cally truncate posteriorly. First abdominal segment vertically 

 truncate at base; epipygium with prominent, acute angles at 

 sides before apex, slightly produced in middle and rounded at 

 apex. Hypopygium produced beyond epipygium, rounded at 

 apex and membranous. Black; antennae, mandibles, a spot on 

 each side between eye and base of antenna, and legs ferruginous. 

 Length 13 mm. 



Hob. — Fremantle, W.A.(Walker). Type in British Museum. 



The male is nearest to Rhagigaster obtusus Sm., which should 

 probably be placed in this genus. The female is without the 

 grooves on the head which are characteristic of Rhagigaster) and 

 the maxillary palpi are apparently four-jointed, certainly not six- 

 jointed. 



Rhytidogaster pyxidatus, n.sp. 



(J. Clypeus broadly subtriangular, almost pointed at apex, 

 strongly punctured and without a carina. Antennae very stout, 

 interantennal carina transverse and almost straight. Head and 

 thorax rugose; median segment more finely rugose, not truncate. 

 Abdomen very closely and shallowly punctured; epipygium rather 

 narrowly produced and truncate at apex, reaching beyond and 

 overarching the curved spine of hypopygium. First ventral seg- 

 ment of abdomen subtuberculate at apex. Black; epipygium 

 ferruginous-red, black at extreme apex. Wings fuscous, nervures 

 black. The division of the first cubital cell is not marked even 

 by a scar. Length 14 mm.
