Crocidium poecilopterum, Loew (1860). 

 Dipt.-Faun. Sudafrikas, p. 195, pi. 11, f. 8. 



A curious fly intermediate between Di^chistns and. Phthiria, and at 

 once recognisable on account of the peculiar wing pattern. 



A male specimen in my collection, from the Cape, Willowmore, 

 January 15th, 1907 (Dr. Brauns). Another male fi'oni Ceres (Cape), 

 Matroosberg, 3500 ft. (R. M. Lightfoot), distinguished on account of 

 its peculiarly spotted wings. 



The male, hitherto not described, is very like the female. The eyes 

 ai'e united in a line as long as the frontal triangle ; their enlarged 

 upper facets occuj)y two thirds of the eye and are of a reddish brown 

 colour, while the lower small facetted part is lighter ; the line of 

 division between them is a very conspicuous one. The facial hairs are 

 longer than the 2 b,asal antennal joints. Frontal triangle white-dusted, 

 as broad, as the ocellar one. Pubescence of body and legs distinctly 

 longer than in the female. Genitalia spheroidal, bilobate, greatly 

 developed, grey-tomentose and white-haired. 



Crocidium nigrifacies, sp. nov. 



Closely allied to iDniiaculatus, Bezzi, on account of its unspotted 

 wings, but at once distinguishable by the completely shiny black, more 

 convex face, and by the black tibiae. 



Type (^ , a single specimen from Bulawayo, September, 1911 (H. C. 

 Pead).

 proboscis 2'5 mm. Head, black, but clothed with dense grey dust on

 part of face being shining black. Occipital border with greyish hairs ; 

 cheeks and lower part >of occiput with long and soft wiiite hairs. 

 Ocellar tubercle prominent, with erect whitish hairs ; eyes rounded, of 

 great size, touching for a space a little longer than the ocellar triangle. 

 Antennae entirely black ; first joint about three times as long as the 

 very short second joint ; third joint as long as the two first joints 

 together, narrow, elongate-oval, with a distinct terminal style. Pro- 

 boscis black, gently curved downwards ; palpi long and thin, acute, 

 pilose at the under side. Thorax entirely black, opaque, but clothed
