suture narrows and disappears lief ore reaching the scutellum. On the 

 sides is another whitish band, broad from the shoulders to the suture 

 and narrow behind. Abdomen testaceous yellow ; excavation of seg- 

 ment 1 black, a narrow medio-dorsal similarly coloured band springs 

 from it, crosses the segment, spreads a little upon the first incision in 

 the shape of a thin black line, intersects further the 2nd and 3rd 

 segments, being either whole or reduced to a triangular spot on each, 

 and ends in a transverse black line on the 3rd incision. 



On each side of this band there exists an elongated spot with white 

 sheen ; on segment 4, the absent black band is occupied by 4 spots 

 with whitish sheen. Hypopygium black. Wings as in M. lusoria ; 

 squamae fulvous. Wings as in M. lusoria, halteres fulvous. Legs 

 black, robust, anterior claws moderately elongated.

MUSCA CONGOLENSIS, 11. sp. 



This is the second species mentioned above, and founded on a $ 



example. 



Smaller and less robust than M. natalensis ; the facies is almost 

 wholly that of M. liumilis Wied. (= angustifrons Thorns.). It differs 

 from the latter by the spaced ciliae of the 3rd nervure on the inferior 

 side of the wing which are situated beyond the small transverse 

 nervure ; it differs also from M. natalensis by the abdomen, similar to 

 that of M. liumilis ; that is to say, the 1st segment is wholly black 

 above. M. congolensis 3 is also noticeable by its very elongated 

 anterior claws and by the apical part of the protarsus of the inter- 

 mediary legs, which is gradually thickened on the inner side.

Signor Bezzi has endeavoured to give a table of the African species 

 of the genus Musca (Boll. Labor. Zool. G-eu. and Agr. vi, 1911, p. 85, 

 Portici) from the descriptions alone of ancient authors. I may be 

 allowed to point out how little reliance is to be placed on the interpreta- 

 tion of these descriptions, too often common-place, by mentioning that 

 M. albomaculata Macq. type ? = M. dorsomaculata Macq. types $ - 

 = convexifrons Thorns. One $ and one ? labelled M. rufiventris 

 (No. 73) in Macquart's handwriting are the same species. They bear 

 a blue label, denoting their African origin, and thus doubtless differ 

 from M. rufiventris, described by Macquart as a Brazilian species.
