together, these latter a little longer than thick and cordiform, hind 

 tibiae almost treble the length of the metatarsus, 3rd and 4th joints 

 hardly longer than thick. Anal segment of ? as long as the 2 

 preceding taken together, gradually thinned into a point curving 

 upwards. Basal joints of the forceps thick and long, more than 

 twice as long as the terminal which is pubescent with some more 

 elongate setae and is widest in the centre. The other characters 

 are similar to those of the preceding species.

2. SUB-FAMILY CHIKONOMINAE, Kieff. 



GEN. CAMPTOGLADIUS, v.d. Wulp. 



CAMPTOCLADIUS NATALENSIS, n. sp. 



$ . Totally black, including the halteres, antennae and legs 

 brownish black. Antennae 13-jointed, 3rd and 4th joints hardly 

 longer than wide, 5th twice as long as wide, the following joints 

 gradually elongated, 12th 3 times as long as wide, joints 2-12 united 

 longer by one-half than the 13th. Wings microscopically setulose, 

 cubitus projecting slightly less than the costal, approaching the alar 

 point much nearer than the upper rarnus of the postical, bifurcation 

 of the postical situated under the proximal 3rd of the radius, distal 

 3rd of the lower ramus strongly arcuate. Legs almost glabrous, 

 anterior tibiae twice as long as the metatarsus, 4th joint a little 

 longer than the 5th, empodium as long as the hooks. Basal joint 

 of the forceps thick, terminal joint slender, pubescent, slightly 

 thinned at the distal end which is void of style, and is almost 

 cylindrical and straight. 



Length : 1-5 mm. Stellenbosch. (L. Peringuey.) 



CAMPTOCLADIUS CAPENSIS, n. sp. 



cf . Totally black. Antennae 14 -jointed, the apical joint once 

 and a half as long as the 12 preceding ones united, 3-4 transverse, 

 11-13 as long as, or a little longer than thick. Wings punctate, 

 without minute setae, costal not prolonged beyond the cubitus, which 

 is a little more distant from the alar point than the upper ramus of 

 the postical, bifurcation of the postical distal from the middle of the 

 radius, lower ramus arcuate in its distal half. Legs with long hairs, 

 anterior tarsi broken, empodium as long as the claws. 



Length : 2'2 mm. Cape Town. (L. Peringuey.)
