whitish scales, only the tarsi blackened at end ; front pair with the 

 coxae clothed with long whitish hairs and some black bristles ; it is 

 moderately abbreviated ; the tibiae are thin and smooth and the tarsi 

 minutely pubescent ; spines of femora black, long, the middle pair 

 with 2, 'the hind pair with 5; claws red, with black tip, and short 

 but acute basal tooth. Wings with a black basal hook and narrow, 

 reddish, black bristly comb ; alula greyish, narrow, transverse, with 

 dark fringe. The venation is the same as in maculosa, but the marginal 

 cross -vein shows a stump in the first submarginal cell before its 



, upper end. 



The markings are the same, but much less dark and more restricted, 

 the discoidal cell being almost entirely hyaline, and the spots at apex 

 being narrower and more separated ; moreover, along the hind margin 

 the dark spots at the end of 4th and 5th vein are completely wanting, 

 the one at the end of the vein between the 2nd and 3rd posterior cells 

 is very faint, and even the spot at the end of the anal cell is less 

 developed. The apical cross-vein of the discoidal cell is not entirely 

 marginated with fuscous, but has only two rounded spots at the 

 two ends. 



EXOPROSOPA (DEFILIPPIA) STRENUA, Loew (1860). 



A beautiful species of great size, very distinct from any other here 

 recorded on account of its red occiput and of the broad, oblique 

 median dark band of the wings. 



Originally described from a female example from the Cape and 

 never recorded subsequently. Duubrody, Uitenhage (Cape), 1899 



(J. A. O'Neil). 



To the good original description the following may be ad 

 Postvertical furrow ^narrow, but bilobate behind ; the indentation of 

 eyes is flat but the bisecting line is long ; vertex less separated from 

 the occiput, with no distinct space or furrow; the borders of the 

 occipital cavity are black ; even the third autennal joint is reddish ; 

 proboscis black, little projecting ; palpi dark yellowish, pale-haired. 

 Mesopleura on middle with black, bristly hairs ; sternopleura with 

 yellow hairs; metapleural tuft entirely yellow. Squamae brownish 

 red, with double fringe, blackish above and yellowish below. Spines 

 of the ovipositor shining red. Front legs much abbreviated, the 

 tibiae being short and thick, smooth, and the tarsi stout, finely 

 pubescent "middle femora with 5-6, hind femora with a complete 

 row of spines; hind tibiae with a dense outer fringe of short, black, 

 bristly hairs among which the discal spines are concealed; claws 

 black, with a short but acute tooth. Alula transverse but rounded,
