This is very near B. musca Hancll. and may prove to be 

 identical, but the antenna? in musca seem to be rather different. 

 The species in this group seem to be very close to each other.

I can see no difference between atrifrons ax\A flarilabris, except 

 in the greater development of the markings on the latter. 



The male has the labrum black ; the eighth joint of the 

 fiagellum slightly produced at the base, the three following joints 

 feebly spined beneath at the apex ; anterior tarsi with a row of 

 well-developed black lobes on the outer margin ; intermediate 

 femora emarginate and serrate in the middle beneath ; second 

 ventral segment with a large, compressed, curved, longitudinal 

 tubercle, third segment with a faint longitudinal carina, sixth 

 segment unarmed. 



Hab. South Perth, W. A. (H. M. Giles). December and 

 January. 



Bembex funebris, sp. n. 



J . Mandibles with one tooth on the inner margin ; labrum 

 longer than the mandibles, shining, very finely and sparsely 

 punctured. Glypeus convex, with very short, fine pubescence. 

 Antennas inserted as far from the eyes as from each other ; the 

 second joint of the fiagellum about half as long again as the 

 third, the seventh emarginate at the apex beneath, the eighth 

 with a small, spine at the base beneath ; a low longitudinal carina 

 between the antennas. Inner margins of the eyes almost parallel, 

 diverging very slightly towards the clypeus. Basal joint of the 

 anterior tarsi not thickened, feebly lobed on the outer margin, 

 with seven spines ; intermediate femora rather feebly serrate 

 beneath. Abdomen rather slender ; the second ventral segment 

 with a compressed, moderately elevated, longitudinal tubercle, 

 not curved at the apex ; the third segment subcarinate longi- 

 tudinally ; seventh and eighth segments longitudinally carinate, 

 the eighth with a short apical spine. Seventh dorsal segment 

 broad, very broadly rounded at the apex. Finely and closely 

 punctured. 



Black ; a spot at the base of the scape, the tibia? beneath, the 

 anterior tarsi beneath at the base, and the femora beneath at the 

 apex pale yellow. A very short and very narrow transverse 

 band, sometimes entirely absent, on each side of the second and 

 third dorsal segments pale greenish grey. Wings hyaline, tinged 

 with fuscous, nervures black.
