last alar 3rd, almost adjoining the radius for more than its 

 proximal half, then united with it at one point, and diverging 

 thence, bifurcation of the discoidal proximal to the transversal, 

 bifurcation of the postical situated under the transversal. Thorax 

 convex, not hooded. Anterior femur with some weak spinules, 

 anterior tibia more strongly spinulose, similar in this respect to the 

 4 hind ones, provided with a simple pecten, anterior metatarsus 

 as long as the 2 following joints taken together, intermediate legs 

 similar to the anterior except that the tibia has no pecten, in the 

 posterior legs the femur is as long as the tibia and 3 or 4 times 

 as thick, subcylindrical and with black numerous spinules, the tibia 

 is as thick as the 4 anterior femora, with the spinules longer than 

 its thickness and bearing a double pecten, metatarsus as long as half 

 the tibia or the 3 following joints united, provided on the ventral 

 side with short, thick, dense setae, 5th joint a little longer than 

 the 4th, none of the tarsal joints cordiform, claws simple, without 

 distinct empodium. Abdomen elongated, sublinear. 

 Length : 2 - 5 mm. Stellenbosch. (L. Peringuey.)

$ . Brown black, mouth, palpi, antennae, and legs yellow, 

 halteres whitish, mouth acuminate, as long as the height of the 

 head. Eyes separated by a line. Second joint of palpi as long as 

 the 3rd and 4th united, thickened at the proximal 3rd, 3rd longer 

 than the 4th and little separated from it. Antennae 14-jointed 

 with a very dense plume, joints 3-10 subglobular, a little trans- 

 verse, 11-14 taken together as long as 2-10 united, 11 arcuate 

 at base, then cylindrical, as long as 12 and 13 taken together, 

 12 longer than 13 by one-half, both cylindrical and having the base 

 swollen and globular, 14 a little longer than 13, subcylindrical, 

 4 times as long as thick, ending in a style. Wings pointed. 

 Cubitus not reaching the middle of the wing, soldered to the radius 

 in its three proximal quarters, bifurcation of the discoidal hardly 

 distal from the transversal, bifurcation of the postical plainly distal 

 from the end of the cubitus. Legs with very long erect, sparse 

 hairs, all the metatarsi a little shorter than the second tarsal joint, 

 hooks very long and strongly falcate, empodium a little shorter than 

 the claws, slender but with long hairs. Terminal joint of the forceps 

 as long as the basal, slender, nearly straight, subcylindrical, a little, 

 thinned at the distal end. 



Length : 3 mm. Stellenbosch. (L. Peringuey.)
