cross-vein a little longer than the discal cross-vein ; first posterior 

 cell as broad as the discoidal one. 



ANASTOECHUS CERVINUS, Loew (18b'0). 



Easily distinguishable by the yellow basal comb of the wings and 

 by the entirely black antennae, the first joint of which is short. A 

 male and a female from the Cape, without precise locality. To Loew's 

 original description may be added : face and geuae destitute of 

 bi'istles ; antennae with the first joint only twice as long as the 

 second ; eyes of the male with the upper areolets a little enlarged, 

 separated for a distance which is only as broad as the fore ocellus (a 

 fact which seems to be contrary to Loew's statement) ; proboscis 

 entirely black, with yellow basal ring ; palpi yellow ; hairs of frons 

 entirely white. Scutellmn red. Abdomen black, with red sides and 

 red hind border of the segments ; its bristles are not longer and not 

 darker than the fur. Front femora with one, the others with more 

 spines below ; pulvilli very short. Wings with the two basal cells, 

 the anal and the axillary cells almost entirely hyaline ; neuration as 

 in the preceding species. 



The female, hitherto undescribed, has a broad frons, which is broader 

 than the eye, and bears on the sides and on the ocella numerous but 

 not very strong tubercles and dark yellow bristles ; face without 

 bristles, rather bare above the upper mouth-edge, and there shining 

 vellow ; proboscis with a black basal ring. Abdomen and venter 

 entirely black, with the hind border of the segments narrowly yellowish ; 

 bristles strong and long, but of a pale yellowish colour like the fur. 

 Hind femora below more reddish yellow, with whitish scales. Wings 

 almost entirely hyaline, the fuscous pattern of the male being only 

 indicated by a hardly distinct greyish tint. 



ANASTOECHUS ERINACEUS, sp. nov., J-, $. 



A very peculiar and bristly, dark species of medium size, very 

 distinct from any other on account of the numerous black bristles of 

 the frons and thorax. 



Type <$ and type $ a single couple from Namaqualand,. 

 Springbok (Cape), November, 1890 (R. M. Lightfoot) ; an additional
