cubital ; the metanotiam between the basal areae is distinctly trans- 

 versely striated and, less distinctly, in the middle below. 



LiMNERIUM MELANOSTOMUM, sp. nOV. 



Black ; the second, third, and the greater part of the fourth 

 abdominal segments and the legs rufo-testaceous, the coxae black ; a 

 narrow rufous line on the hinder orbits ; wings hyaline, the stigma 

 dark testaceous, the nervures black ; the areolet obsolete. 3 ■ 



Length 8 mm. 



Cape Colony. Neighbourhood of Cape Town. 



Head and thorax finely, closely punctured, and covered with short 

 white pubescence ; the depression above the antennae shining, 

 smooth, and with two or three keels. Metanotum long ; its base 

 depressed, smooth, shining ; petiolar area longer than broad, widened 

 at the apex ; areola twice longer than wide, widened and rounded at 

 the base ; postei'ior median area narrowed at the base, punctured 

 there, the rest transversely striated ; the segment is more strongly, 

 closely rugosely punctured than the mesothorax. The apex of the 

 discoidal nervure and the recurrent are largely bullated ; the 

 recurrent nervure is received very shortly beyond the transverse. 

 cubital. 



LiMNERIUM LONGICEPS, Sp. nOV. 



Black ; the mandibles, palpi, tegulae, and the four front coxae and 

 trochanters stramineous, the rest of the four anterior legs fulvous ; 

 the hind coxae and basal joint of trochanters black ; the apical joint 

 of the latter straminous, the femora dark fulvous ; the tibiae pale, a 

 fuscous band near the base and a larger one at the apex ; the tarsi 

 fuscous, the basal joint broadly white at the base. The second 

 abdominal segment rufous at the apex and along the sides. Wings 

 hyaline, the stigma and nervures fuscous ; the areolet small, the 

 nervures thick ; the pedicle nearly as long as the apical branch. ? . 



Length 4-5 mm. ; terebra 1 mm. 



Cape Colony. Cape Town. 



Head and thorax alutaceous, covered with a short, white pubes- 

 cence ; the face with long silvery hair. Face longer than usual, 

 owing to the longer malar space, which is as long as the antennal 

 scape. Metanotum indistinctly areolated ; there is a small, indistinct 

 petiolar area followed by a long pedicle from w^hich branch off keels 

 which border the apical slope ; there are two lateral areae indistinctly 

 separated ; the apical gradually narrowed to a sharp point at the 

 apex ; spiracular area moderately distinct.
