Habitat: Australia — Queensland (Brisbane). 

 Type: No. Hy 1192, Queensland Museum, Brisbane, one fe- 

 male on a card. 



2. Xanthosomoides fiilvipes, new species. 



Female. — Length, 4.2 mm. excluding the ovipositor, the latter 

 exserted for a length nearly equal to that of the body. The same 

 as macidatipennis , but much more robust; also the pronotum is 

 nearly as dark as the scutum, its caudal margin contrasting lemon 

 yellow followed by a narrow black stripe running across the ce- 

 phalic margin of the scutum; the propodeum is wholly black or very 

 dark, the ovipositor fuscous, the meson of the thoracic venter is 

 black and in the venter of the prothorax there is a distinct tri- 

 angular black marking like the Greek letter Delta of the capital 

 case. The postmarginal vein is slightly longer than in the first 

 species, the apparent petiole of the stigmal spot in the fore wing also 

 longer. Vertex dark ochreous, the face lemon yellow. The wings 

 are large. First funicle joint longer, cylindrical, more than twice 

 longer than broad at apex.

 specimen on a card. 



Melanosomellini , new tribe. 



Antenna? 12-jointed, with one ring-joint, the club 3-jointed, the 

 male antennae different and bearing long ramii ; otherwise as in the 

 Eurytomini and Rileyini as limited by Ashmead. The marginal 

 vein two and a half times its own width, but shorter than either the 

 stigmal or postmarginal veins. Probably differing totally in habits 

 from the Rileyini, since the latter appear to be egg parasites of the 

 Orthoptera. The following genus: 



 Melanosomella, new genus. 



Female. — Head (cephalic aspect) slightly wider than long, the 

 antenucc inserted slightly below the middle of the face, the scrobes
