/'<';/;<//( Characters. 1 1 cad flattened, seen from above about twice 

 as wide anteriorly as at the base, but little longer than the width in 

 the widest part ; clypeus short, at the apex truncate ; mandibles with- 

 out a tooth; malar space not as long as half the width of the eye; eyes 

 in outline oval; trophi wanting but according to Ashmead (1899) the 

 ninxillarv palpi are 4-jointed and the labial palpi 3-jointed; pronotum 

 seen from above quadrate, at the anterior lateral angles tuberculate, 

 without a median sulcus ; propodeum broader than rest of the thorax, 

 a little longer than the meso- and metanotum, the posterior face 

 truncate; claws with an erect inner tooth, not cleft as Ashmead (1899) 

 says ; gaster a little longer than the other two parts of the insect ; the 

 second dorsal segment does not differ from the others, the apical two- 

 thirds of the segment is depressed, more broadly so in middle, and 

 shining, the basal part with distinct punctures; the sixth ventral seg- 

 ment is shining centrally, the lateral part irregularly rugose ; hypo- 

 pygidium a little more than twice as long .as the basal width, narrowing 

 apically where it is truncate, shining impunctate, a tuft of long hair 

 on each side near the apex ; apical dorsal segment with a convex, 

 shining, somewhat boat-shaped area, rather wider apically and nearly 

 three times as long as the greatest width ; a long tuft of hairs from 

 a little below the middle at the side of this convex area. 



In Turner's table this runs out at category II. 



Iswaroides kobelei Ashmead. 



Male. Length 11.5 mm. Head and clypeus closely distinctly punc- 

 tured except on the front where the punctures are confluent ; thorax 

 similarly punctured, the punctures on the propodeum rather finer ; 

 the basal part of the segments of the gaster with distinct poorly de- 

 fined punctures ; when seen from behind the ventral segments appear 

 to have small tubercules at the lateral margins; the space between the 

 spines broadly arcuate, the middle spine curved upward apically. Black 

 tibiae and tarsi slightly brownish; the scattered hairs silvery; wings 

 dusky hyaline, venation black. 



Female. Length 5.5 mm. Head shining and, except for a few 

 widely scattered punctures, impunctate ; a median furrow between the 

 antennae ; pronotum finely striatopunctate ; propodeum shining, slightly 

 impressed in the middle; legs rather strongly spinose ; basal part of the 

 segments of the gaster with distinct punctures. Head ferruginous, 

 the legs, thorax and abdomen pale piceous; hair white or gray except 

 that at the apex of the gaster, which is rufous. 



Type locality : Australia. A male and female, supposed to 

 be in coitu, taken by Mr. A. Koebele.
