UFENSIA new genus. 



Female: The same as Ufens in all structures, but the abdomen is longer, 

 pointed conic-ovate, longer than the thorax, the ovipositor long, inserted 

 at base of abdomen and distinctly exserted, the valves projecting beyond 

 the tip of the abdomen for a length equal to about a third or somewhat 

 less, the abdomen's length. Marginal and stigmal veins short, the former 

 nearly a third shorter than the latter which is well-developed. Strigils 

 absent. Mandibles apparently tridentate. The funicle twisted, the 

 club 3-jointed. 



Male: Not known. 



This genus is omitted from my table of Australian genera of 

 the family now (October, 1912) in course of publication; it would 

 fall near Neobrachistella Girault because of the exserted ovipositor. 



Type: The following species. 



Ufensia pretiosa new species. 



Female: Length, 1 .00 mm . , including the ovipositor which is about 0.20 mm . 

 long. Similar to the Australian species of Ufens (more nearly to herculcs) 

 but differing in specific details. Black, the head except occiput and the 

 base of the abdomen in the centre of the dorsum, orange yellow. Antennae 

 dusky pallid, the club more or less obscurely banded by two pallid bars. 

 Legs black, the articulations, knees, tips of tibia? and proximal two tarsal 

 joints white, the posterior tibia? nearly all white, the proximal two-thirds 

 obscurely dusky. Wings hyaline, the venation black. Ovipositor black. 



Posterior wings with three long lines of discal ciliation, the fore wings 

 bearing about nineteen lines. Marginal cilia of fore wing very short. 

 Distal tarsal joint longest. 



From a single specimen, -inch objective, 1-inch optic, Bausch and 

 Lomb. 



Male: Not known. 



Described from a single female captured by sweeping grass in a 

 forest near Nelson, N. Q., October 10, 1912. 



Habitat: Australia, Nelson near Cairns, Queensland. 



Type: No. Hy. 1173, Queensland Museum, Brisbane, the fore- 

 going female in xylol-balsam mounted with an OUgosita. 



GENUS PROSPALTELLA Ashmead. 



Prospaltella bears an oblique, short but nonsessile stigmal vein ; 

 Coccophagus bears usually a short sessile one, at right angles to 

 the marginal vein as in the Entedonini. 



Prospaltella nigrifemur new species. 



Female: Length, 0.75 mm., including ovipositor. Sooty black, the wings 

 hyaline, the ovipositor exserted for a fourth (more or less) the length of the
