﻿On the Boinhylikl Fauna of Soiifh Africa (Dijdera). 155 



Wiedemaun lias described tliis species from the Cape ; it is recorded 

 only by the oldest authors. The species described under the same name 

 by Macquart seems to l)e a different one, as the anteunal style is said 

 to be distinct, but Wiedemann slates that the third joint is thickei' 

 than usual. 



There is in the collection a sinyle specimen from O'Okiep, 

 Namaqualand (Ca.pe) (L. Pcringuey), 1905. 



Third antennal joint H times as long as the two preceding together, 

 elongate conical, rather linear, not In-oadened at base and without 

 distinct terminal style. Face conically produced, Avith dense pale 

 yellowish scales ; proboscis not projecting. Thorax with black 

 bristles ; pleui'ae with only yellowish hairs, even on the metapleura ; 

 sternopleura with yellowish scales. Scutellum red, with black base 

 and black bristles at the hind border. Squamae pale yellowish, with 

 whitish fringe. Legs entirely yellowish, witJi whitish scales; front 

 pair much abbreviated, with the tibiae thick and short and Ijeset with 

 distinct spicules, the tarsi shortly pubescent ; claws thin, with reddish 

 base and short but acute basal tooth. Wings with small, yellowish or 

 Avhitish tomentose basal comb; second vein originating at a considerable 

 distance from the discal cross-vein, with not deep but duplicated 

 terminal looj» ; marginal cross- vein V-shaped, much retreating; first 

 posterior cell narrowed at end, only a little broader than the anal cell ; 

 discal cross- vein placed in the middle of the discoidal cell, which is 

 not dilated below at end and has a V-shaped terminal vein, which is, 

 however, less obliquely set ; third posterior cell considerably shorter 

 than the fourth at the base. Axillary lobe long and narrow ; alula 

 infuscated, and with a darkish fringe.

The species of the present group are often confused, and seem to be 

 peculiar to the South African Fauna ; they are closely allied in 

 venation with some species of the following group, but have a much 

 less defined and less dark wing pat-tern ; characteristic also of the 

 group are the isolated dark spots on the hind half of the wing, which 

 are rarely wanting. 



ExopROsoPA (Exoprosopa) inpumata, Bezzi. 



Closely allied "with clnta, but at once distinguished by its sharply 

 defined wing-pattern and by the posterior half of the wing being 

 distinctly smoky.
