ADELIDEA BRAUNSI, n. sp. 



A small species, at once distinguished by the equally infuscated, 

 not spotted wings, which have, moreover, a short discoidal cell. 



Two 9 specimens from Willowmore (Cape), April, 1920 (collected 

 by Dr. H. Brauiis, in whose honour the species is named). 



The present species cannot be the A. fiLscipennis of Macquart as 

 one may conclude from the name, the wings being described as 

 yellowish at base and dark spotted. 



$ . Length of body 4-4*5 mm. ; of wing 5-6 mm. Head black, 

 densely clothed with dark grey dust; occiput with dense yellowish hairs ; 

 frons broader than one eye, with short black bristles on the sides. 

 Antennae quite black, the first joint with scarce black hairs ; third 

 joint as long as the 2 first joints together, with a short black terminal 

 style. Face rounded, convex, blackish brown, with short blackish 

 hairs at sides and at mouth border. Palpi black, long ; proboscis 

 black, 3-3'5 mm. long ; beard scarce and yellowish. Thorax entirely 

 black, with reddish humeri ; on the back it is clothed with yellowish 

 tomentuni, and has numerous yellowish bristles at sides, the supra- 

 alar ones being darker ; on the pleurae the tomentum is more grey, 

 and there are yellowish hairs only on the nieso- and sternopleura, the 

 rest being bare. Squamae blackish, with scarce yellowish fringe ; 

 halteres whitish. Scutellum entirely black and rather shiny, clothed, 

 like the back of the mesonotum, with several rows cf blackish bristles 

 at hind border. Abdomen entirely black, rather shiny and yellowish 

 tonientose ; first segment with dense white hairs at sides ; a row of 

 blackish thin bristles at hind border of the segments. Venter entirely 

 black, yellowish tomentose, clothed with dark hairs. Legs reddish, 

 with black coxae and black tarsi except at base ; the femora are 

 blackened near the base; all the bristles arid spicules reddish or 

 yellowish ; hind femora below without bristles, but with a row of 5-6 

 at the outer side near the end. Claws reddish, with black tips ; 

 pulvilli short, yellowish. Wings equally and rather intensely iuf uscated, 

 almost blackish, without darker spots on cross-veins, but with a 

 broad whitish praediscoidal spot, which is very striking against the 

 infuscation. Basal comb not distinct, alula rounded, blackish, without 

 fringe. Venation as in two preceding species, but the first posterior
