PHYTOPHAGOUS AND PARASITIC HYMBNOPTBRA. 85 



21. — Iphiaulax Kirhyiy sp. nov. 



Luteous ; antennae black ; wings yellowish-hyaline, the apex 

 with a fuscous border ; the base and apex of stigma black, the 

 rest of it and the nervures yellow, a small black cloud at the base 

 of the first cubital cellule, between the radius and the cubitus, 9. 



Length 9 mm. ; terebra 7 mm. 



Kandy. 



Sparsely covered with fulvous pubescence. Face irregularly 

 rugose, covered with pale pubescence. Front and vertex smooth 

 and shining, bare ; the former deeply depressed with a deep, 

 clearly defined furrow in the centre. First and second abscissa 

 of radius united equal in length to the third ; the cloud at the 

 stigma may be continued along the basal abscissa of cubitus. 

 Middle area of first abdominal segment irregularly, longitudinally 

 striated, intermixed with some transverse striae ; the lateral de- 

 pression with some transverse keels ; the second segment coarsely 

 reticulated in the middle ; the basal area triangular, smooth ; the 

 oblique furrow on the lateral depression crenulated ; the keel at 

 the basal area short, indistinct. Suturiform articulation stoutly 

 crenulated, as are also the furrows on the apex of the third and 

 fourth segments ; they are closely punctured.

 Plate A, %. 7. 



Head, thorax, antennal scape and four front legs ruf ©testaceous ; 

 the abdomen black, the fifth and following segments bright

 wings yellowish-hyaline, paler at the apex ; the middle tibiae 

 covered thickly with pale pubescence ; the hinder still more

Kandy. 



Antennal scape thickly covered with long fulvous hair. Face 

 coarsely rugosely reticulated. Thorax smooth and shining ; the 

 apex of median segment black. The central area of basal 

 segment of abdomen stoutly keeled in the middle ; the keel 

 bordered by stout oblique striae. The second segment is strongly 

 longitudinally striated ; the basal area small, triangular, smooth, 

 followed by a stout keel which runs to the smooth apex ; the third 

 is similarly striated, but with a broader smooth apical area ; both 

 segments are depressed laterally; the suturiform articulation wide, 

 deep; on the fourth segment, shortly behind the middle, is a trans- 

 verse furrow which is irregularly striated in the middle. The 

 basal abscissa of the radius is broadly roundly curved towards
