PROCERATONEURA new genus. 



Type: Ootetrastichus lustris Girault. 



Petiole wider than long yet rather distinct. Club joints subequal. Propodeum without" 

 a median carina except a weakly indicated one; other carinse absent. The pedicel is short,, 

 distinctly shorter than funicle 3 in spite of the statement in my table of species of Ootetrastichus- 

 where the contrary is stated. The original description of the species is correct. Type 

 re-examined. 



A second female has been examined captured by sweeping in forest, August 5, 1913 

 (A.A.G.), Gordonvale and a third same place, April 12, 1914. The first funicle joint is stouter 

 and a little longer than the other two, distinctly not twice longer than wide. The third tooth 

 of the mandible is truncate. Like Ootetrastichus otherwise but the three distal ring-joints are 

 transverse-linear, the first large and the club is short and equally divided, subequal to funicle 1.

Female: — Head (cephalic aspect) triangular, the antennae inserted in the middle of the- 

 face, 11-jointed, with three ring-joints, the club 3-jointed. Hind tibial spurs single, enormously 

 elongated as in Euplectrus, over half the length of hind tarsus. Venation normal. Scutum 

 with a median groove, the scutellum with four, each of the inner two near the meson. Pronotum 

 as in the Eurytomidse. Propodeum with a V-shaped median carina and a curved lateral one.. 

 Abdomen with a short, stout petiole, cylindrical, the segments unequal. Mandibles tridentate. 



Male: — Not known. 



Type: The following species.
