This is a typical Dryinid, much resembling Gonatopus, but differ- 

 ing from this genus and its allies by the simple fore tarsi of the 

 female. From other Dryinidse it differs by the i2-jointed antennae. 



ALGOA, new genus. 



Female. — Entirely apterous, elongate, thorax constricted medially. Head 

 seen from above one half wider than thick antero-posteriorly but thin above, 

 the front sloping back sharply above the antennae which are inserted close 

 together in lateral depressions just above the cljT)eus ; 12-jointed, simple, 

 short, thinner apically. Eyes bare, small, very elongate, over twice as long as 

 broad, separated by their width from the vertex and from the base of the 

 mandibles. Mandibles long, acute, widely separated at the base, with three 

 microscopic teeth on the inner side at the tip. Maxillary palpi 6-jointed; 

 first joint very short, third with a spine at its tip. Labial palpi 4-jointed. 

 Cheeks and temples margined behind, the head concave posteriorly inside the 

 margin. Thorax narrowed medially, widened out both in front and behind, 

 prothorax as long as the mesonotum and metanotum together. Mesonotum 

 very short, medially elevated, with two foveate, indistinct furrows. Metano- 

 tum wider behind, arcuately excised, with the hind angles produced and the 

 posterior surface concave. Abdomen as long as the thorax, with six segments 

 of which the second is the longest, distinctly constricted at the base of the 

 second segment both above and below. Legs stout, smooth, the anterior 

 femora especially large and swollen. 



Algoa heterodoxa, new species. (Fig. 4.) 



Female. — Length 2.5-5.2 mm. Piceous, the basal three joints of the 

 antennae, the mandibles and the legs, except the base of the coxae and all the 

 femora much lighter, yellowish-brown. Head highly polished, not punctate, 

 ocelli visible in certain lights as faint dots arranged in a large triangle. Scape 

 of antennae as long as the first flagellar joint; pedicel two thirds as long; 

 second flagellar joint three fourths as long, following of about equal length, 

 but growing thinner. Thorax brownish pubescent except on the pro- and meso- 

 pleurae, not sculptured, metanotum behind with a marginal carina. Abdomen 

 brownish pubescent, sessile ; first segment with its declivous basal portion sepa- 

 rated by a carina ; second segment as long as wide, more than twice as long 

 as the first and equal to the following three taken together ; third to fifth 

 gradually shorter. Tibial spurs i, 2, 2. Hind legs moderately stout, the 

 tibiae smooth ; middle legs with the femora swollen ; those of the anterior legs 

 enormously enlarged, obovate. Fore tarsi one half longer than their tibiae ; 

 those of the other legs nearly twice as long. 



Described from four specimens collected by Dr. Hans Brauns at 

 Algoa Bay, Cape Colony, during December and April. 



This remarkable species is of doubtful relationship but has strong 

 affinities with the Sclerogibbini, for the thorax, abdomen and legs
