HYPERALONIA COLEOPTRATA, sp. nov., . 



A middle-sized species with wholly black wings, closely allied to 

 nigripennis, but distinguishable by the different antennae and by the 

 bright red hairs on the sides of body. 



Type $ , a single specimen from Stella Bay, Natal, January, 1915 

 (H. W. Bell-Marley). The present species cannot be considered as 

 identical with A. rufa, Wiedemann, because this author states that the 

 wing venation and the antennae are as in Lomatiabelsebut, and because 

 the species is not placed in the ' Erste Horde,' pi. iii, fig. 1, which 

 contains the Hvperaloniae, a subfamily very well interpreted by this 

 early writer. Length of body 11 mm. ; of wing 11 mm. Head black, 

 dark reddish-brown in the lower part ; occiput with yellowish central 

 fringe, with narrow and simple postvertical furrow and with yellowish 

 tomentose postocular stripe ; eyes with a broad but not deep in- 

 dentation and with a long bisecting line ; frons at vertex a little more 

 than three times as broad as the short, rounded, reddish ocellar 

 tubercle, and having short and dense erect, black hairs and reddish- 

 yellow scales in front. Face distinctly conical but not much produced, 

 with reddish scales, black short hairs in the centre at the upper mouth- 

 edge and reddish hairs on the sides underneath. Antennae short, the 

 first joint black with deep, black, short hairs ; the second globular, 

 red, black-haired ; the third black, shortly conical, as long as the two 

 first joints taken together, with a very short and stout terminal style ; 

 proboscis black, thick, shorter than the mouth ; palpi yellow, pale- 

 haired. Thorax elongate, rather narrow, entirely black, clothed on the 

 upper side with dense black hairs and black scales, but with reddish 

 hairs in front of the scutellum ; collar and notopleural tuft entirely 

 bright red ; supra-alar stripe reddish ; macrochaetae strong and long, 

 black ; pleurae grey-dusted, with scattered black hairs and reddish 

 tomentum on the steruopleura ; metapleural tuft bright red. Scutelluin 

 dark red, with a black, black-scaled base, clothed with reddish dust 

 and bearing black bristles behind. Squamae reddish brown, with 

 reddish yellow fringe; plumula reddish, halteres yellowish, with
