OF WASHINGTON*, VOLUME XVI, 1914 1 1 7 



low at proximal half or nearly, the proximal margin of the black cuneately 

 scooped out. Tarsi dusky. Wings subhyaline. Fourth funiclar joint 

 longer than the club. Mandibles 5-dentate. 



From one specimen, similarly magnified. 



Female: Not known. 



Described from a male captured by sweeping foliage and grass 

 in an open forest at Proserpine, Queensland, November 3, 1912. 

 Like impudens but differing in the coloration of the legs and abdo- 

 men, the band of the latter much broader; also somewhat like 

 minor but differing in the coloration of the legs, especially the 

 femora. 



Habitat: Australia, Proserpine, Queensland. 



Type: No. Hy. 1280, Queensland Museum, Brisbane, the above 

 male mounted in xylol-balsam. 



Later, a second male was found, collected at the same time; in 

 this specimen the femora were nearly wholly black. 



Elasmus fasciativentris new species. 



Female: Length, 2.5 mm. Metallic green but very dark, the proximal 

 two-thirds of the abdomen orange yellow, immaculate and extending farther 

 caudad on the venter but along the dorsum crossed by four conspicuous 

 broad blackish bands, the widest of which is at the base of the abdomen 

 and is metallic ; there are thus in the centre of the dorsum three broad black 

 bands of about equal width and not extending into the dorso-lateral aspects. 

 Tip of abdomen black for some distance (about distal third) . TegukE, post- 

 seutellum, oral area broadly, scape and legs pale lemon yellow, the latter 

 still paler, including the coxse, the tarsi blackish, the caudal coxa with its 

 proximal two-thirds metallic green, the caudal tibia with the usual arrange- 

 ment of black spines. Flagellum blackish, the pedicel lighter. Wings 

 subhyaline, the venation dark. Funiclar joints subequal, longer than wide, 

 the first somewhat longest, longer and stouter than the pedicel. Face with 

 thimble punctures. 



From one specimen, similarly magnified. 



Male: Not known. 



Described from a single female captured by sweeping grass and 

 foliage in a forest at Nelson, N. Q., November 28, 1912 (Alan P. 

 Dodd). 



Habitat: Australia, Nelson (Cairns), N. Q. 



Type: No. Hy. 1292, Queensland Museum, Brisbane, the above 

 specimen on a tag. 



Elasmus australiensis has the postscutellum wholly lemon 

 yellow; also vicinus; the latter should therefore be grouped with 

 flavipostscutellum; insularis has a narrow transverse yellow band 

 across the base of the same sclerite.
