DiscHisTus cAPiTO, Loew (1860). 



A species of great size (for the present geuus), very near niydax, 

 but at once distinguislied. from it and from the others ))\' tlie characters 

 given in tlie table. 



Originally described from Caft'raria. There is in the collection a 

 male specimen from Grahamstown, May, 1885 (Billinghurst), measuring 

 12 mm. of length with 25 mm. of wing-spread; it was named by 

 Bigot DiscMstus heterocerm, Macq. ; but Macquart in its description 

 says that the third antennal joint is s])indle-shaped and that the legs 

 are yellow — characters which apply better to viysta.v, with which 

 therefore it must be placed as a synonym. 



The male was unknown to Loew and is hitherto undescribed ; it is 

 very like the female. The eyes have equally small areolets, and are 

 set close to each other on the frons but separated f(n- a distance wdiich 

 is as broad as the ocellar tubercle ; the genitalia are l)laclc, Avith reddish 

 borders to the lamellae; the black bristles of the abdomen fcn-ni 

 cduiplete rows and are very numei'ous. All the femora are provided 

 on the underside with long and numerous, rigid, black hairs, with 

 some yellow ones intermingled chiefly near the base and on the middle 

 pair. The pulvilli are only a little shorter than the claws. Wings 

 with the discoidal cell long, tlie two middle segments of its lower vein 

 being of equal length ; basal comb not distinct ; alula very small and 

 destitute of fringe. 



DiSCHISTUS PLUMIPALPIS, sp. UOV., (^ . 



Closely allied to inystax and rapito, but at once distinguished by the 

 long proboscis, the feathered palpi and the much more approximate 

 <'yes of the male. 



Type (^ , a single specimen from Grahamstown (Cape), 1883. 



Length of the body 10"5 mm. ; spread of the wings 22 mm. Head 

 l>lack, grey-dusted ; occiput flat, concave in the middle, with rather
