South African Higher Myodarii (Diptera Calyptratae). 471 



type of Hough, form above the insertion of the antennae an arc of 

 circle situated between the orbital setae and the genae. 



PLEROPELETERIA PERINGUEYI, u. sp. 



Pleropeleteria peringueyi resembles Chaetopeleteria popelii Portsch. 

 and is of the same colour. It differs, in addition to the sub-generic 

 characters given above, by the somewhat wider frous ; in the genae 

 the width from top to bottom is equal. Antennae and chaetae blackish ; 

 legs entirely black. The thorax bears 4 dorso-central setae behind the 

 suture. 



Length 11 mm.

GEN. MICROPALPUS Macq. 



MlCROPALPUS CAFFER, 11. Sp. 



Resembles so much M . prohecate Speis., that the examples belonging 

 to the Hofmuseums, Vienna, have been wrongly identified with it by 

 Speiser himself. It differs by: (1) The presence on the second and 

 third abdominal segments of sharp bristles interpolated on one side 

 with the discal setae and on the other with the marginal ; (2) the 

 presence on the medio-ventral region of robust bristles on each 

 segment, as in Dejeania Rob. Desv. The antennae are dark rufous, the 

 legs are testaceous, including the tarsi, which are provided in the $ 

 with long claws and yellowish pulvilli. 



The size is that of M. prohecate, the abdomen, which is also without 

 medio-dorsal baud, is a little wider and more massive, the colour varies 

 from yellowish testaceous (Natal) to mahogany red (Nyassaland). 

 Examples from Tanganyika are brownish red, and have smoky wings 

 .and somewhat brownish tarsi. 



Several examples. Natal. Durban CH. W. Bell-Marley), S. Afric. 

 Museum ; Nyassa, Mt. Mlaiije (S. A. Neaves), Eiitom. Research 

 Commission ; Tanganyika region (Grrauer), Vienna Museum. 



MICROPALPUS PARCESETOSUS, n. sp. 



Elongate ; characterised by the small number of frontal setae and 

 by its sexual dimorphism, the $ having the facies of M. anyulicornis 

 Speis., the resembling altogether M. frater and M. lithosiophaga 

 Rond. 



$ . Face whitish, orbits yellowish, antennae blackish, third joint 

 wide, partly obscure rufous ; proboscis as usual, palps comparatively
