it by a transverse furrow. Head and thorax shining, sparsely 

 punctured and haired. 



The legs are moderately long and stout ; the hind coxai 

 are about three times longer than wide ; the fore calearia 

 curved, slender, simple. The hypopygium is large, but does 

 not project much ; above it is a short stumpy projection — 

 the apex, apparently, of the penultimate segment. The 

 abdomen is sessile^ the basal segment being very short and 

 smooth. 



The species on which Pycnostigmusinae is founded 

 cannot well be placed in any of the subfam'lies hitherto 

 recognized. The alar structure is very peculiar; there is 

 neither radius nor cubitus, the place of these being taken by 

 the large horny pyriform stigma, or stigmal branch (if that 

 is a more appropriate term). This character, with the larger 

 number of antmnal joints, should rcKlily separate it from 

 the Figitinse and Eucffilinie, with which it is otherwise most 

 nearly allied. There is no known Tlymenopteron with such 

 a peculiar horny structure on the wings. 



Pi/cnostifjmus rostratas, sp. n. 



Black, shining, the knees testaceous; the head, antennre, 

 and legs thickly covered with white pubescence ; wings 

 hyaline, the nervures testaceous, the stigma darker, more 

 piceous in tint. Face with scattered punctures in the centre, 

 the sides aciculated ; clypeus smooth and shining. Pro- 

 notum finely rugose, the apex with pitted punctures ; the 

 mesonotum with scattered shallow punctures. Scutellum 

 coarsely, irregularly, rugosely punctured. Metanotum wiih 

 two stout keels in the centre, which is irregularly transversely 

 striated ; the apical half on either side of these stoutly 

 obliquely striated, almost reticulated. Propleune above 

 coarsely rugosely punctured ; the lower part, especially at 

 the base, striated. Base and lower part of mesopleurre 

 irregularly punctured-striated, the rest smooth and shining. 

 Metapleurse coarsely aciculated and irregularly striated. 

 Abdomen smooth and shining. Wings hyaline, iridescent; 

 the apex ciliated. ? . 



Length 3 mm. 



Cape Town, September (South African Museum). 



The antennaj are as long as the body, are not raucli 

 thickened towards the apex ; the pedicle is twice longer 

 than broad ; the third and fourth joints are about equal in 

 length ; the last is conical and twice the length of the 

 penultimate. Cheeks margined. The eyes appear to be 

 slightly hairy ; they are probably rubbed.
