Descriptions of Neic Species of Parasitic Hyvicnoptera. 29 



Alitha longipennis, sp. nov. 



Black, shining, the legs fuscous, lighter, more testaceous in colour 

 at the base ; wings large, longer than the body, hyaline, the stigma 

 and nervures fuscous. ? . 



Length 3 mm. ; ovipositor 1 mm. 



Cape Colony. Stellenbosch Distr. 



Antennae 25-3ointed, the flagellum thickly covered with a short, 

 black, stitf pubescence. Mandibles fuscous, broad, a short, minute 

 sharp, curved tooth at the apex, followed by a round incision. On 

 the lower outer orbits are two stout keels, separated by a furrow. 

 Temples broadly roundly projecting. Occiput roundly incised. 

 Parapsidal furrows united at the apex and prolonged as a short 

 branch, which does not extend to the scutellar depression. The 

 latter is large, deep, and with a narrow keel in the middle. Apex 

 and sides of metanotum strongly aciculated. The centre of the 

 apical part of the first abdominal segment is coarsely aciculated, the 

 sides have a shorter striated band. Third abscissa of radius about 

 one-half longer than the basal two united ; the cubitus does not 

 reach the apex of the wings ; second cubital cellule of equal width 

 throughout, twice longer than wide ; the apices of both wings are 

 closely ciliated. 



The abdomen is not quite so long as the thorax ; its first segment 

 is slightly longer than the second.

PEEILITUS, Nees. 



Perilitus ruficollis, sp. nov. 



Black, the head, pro- andmesonotum,pleune, the third and fourth 

 segments of the abdomen and the legs, red ; wings hyaline, the 

 nervures and stigma dark fuscous. <? . 



Length 4-5 mm.

Antennae longer than the body ; the flagellum covered with white 

 pubescence ; the third joint not much shorter than the following two 

 united, the scape as long as it, slender. Parapsidal furrows deep, 

 obscurely crenulated, not reaching to the scutellum. Scutellar 

 depression wide, obliquely sloped at the apex. Metanotum opaque,
