llymenopterous Genus Tiphia. 127 



Black ; the mandibles, the scape of the antennse at the 

 apex, the flagellum more distinctly beneath than above, the 

 apex of the femora, the spines of the tibise and tarsi, and the 

 extreme apex of the pygidium fusco-ferruginous ; the 

 extreme apex of the pronotum, of the teguhe, and of the 

 abdominal segments testaceous; the pubescence whitish. 

 Wings hyaline, very faintly tinged with yellowish brown, 

 most strongly in the radial cell ; nervures fusco-ferruginous. 



Length 13 mm.

Near T. natalensis, Sm., from which it may be distinguished 

 by the longer tegula?., the smaller stigma, the sculpture of 

 the median segment, and the less marked constriction of the 

 apex of the first abdominal segment.

Tiphia abrupta, sp. n. 



? . Clypeus very delicately punctured ; the head rather 

 coarsely, but not very closely punctured, least closely round 

 the ocelli. Pronotum rather coarsely and very closely 

 punctured, the posterior margin narrowly smooth and shining ; 

 the propleurre finely striated, smooth and shining at the 

 summit ; the mesopleurse closely, but not very coarsely 

 punctured ; mesonotum and scutellum punctured, the punc- 

 tures larger and more scattered than on the pronotum. 

 Median segment short and broad, opaque and finely rugulose, 

 the median carina reaching the apex, the two outer carinse 

 rather far apart, converging slightly towards the apex, the 

 distance between them at the apex about three-quarters of 

 that at the base ; the sides of the segment obliquely striated. 

 Tegulse closely punctured, the extreme apex smooth and 

 shining. Abdomen shining, closely punctured, the two basal 

 segments a little more sparsely than the others, the basal 

 segment very abruptly truncate at the base, rather strongly 

 constricted at the apex, the apical margin of all the segments 

 very narrowly smooth. Epipygium longitudinally punctured 

 rugose, the apex broadly smooth and shining. The stigma 

 is large and the radial cell very broad.
