NOVITATES /^OOI.OGICAE XXI. li)H. 271 



"(2) Setae scutelli apicales lougae, robnstae, cruciatae, et non erectae ; setae 

 2 praeapicales longae, erectae, et divergeutes (Dr. Hartert's specimen is anomalous 

 in having onlj' a single seta praeapicalis media). 



" (3) Geuae sparsim pilosae. 



" (4) Arista anteunarum usque ad apicem iiicrassata ; articnlo basali elongato. 



" (5) Setae tantum marginales in segmentis. 



" (6) Tarsi antici non dilatati. 



" (T) Vibrissae prope marginem oris." 



It has been thought better to await the arrival of further material of both sexes 

 before naming and characterising in detail the new genus and species referred to- 

 above, especially since the only specimen at present available for examination is not 

 altogether in perfect condition. 



SARGOPHAGINAE. 



Genus SARCOPHAGA Mg. 



Sarcophaga sp. in cert. 



One ? from the sands of El Arich, south-west of Touggourt, Southern Algeria, 

 8-9. vi. 1912 (Dr. E. J. 0. Hartert and C. Hilgert). 



According to Dr. Villeneuve, this species is very probably Sarcophaga haemor- 

 rhoidalii Mg. (Syn. S. nurus Roud.). 



Genus WOHLFAHRTIA Br. and v. Berg. 

 Wohlfahrtia brunnipalpis Macq. 



{Dipt. Exnt. iv. Supp. p. 230 [Aip-ia] (1850).j 



One i and one ? from El Golea, Algerian Sahara, li)-13. v. 1912 (Dr. E. J. 0. 

 Hartert and C. Hilgert) ; two i S from the south of Ghardaia, Southern Algeria, 

 26-30. V. 1912 (Dr. E. J. 0. Hartert and C. Hilgert); one ? from the sands of El 

 Arich, south-west of Touggourt, Algerian Sahara, 8-9. vi. 1912 (Dr. E. J. 0. Hartert 

 and C. Hilgert). The British Museum ("Natural History) previously possessed two 

 a of this species from the vicinity of Biskra, South Algeria (along the Route des 

 Ziban, and on the dunes 6:^ miles from the town), 17, 18. v. 1893 (Rev. A. E. Eaton). 

 It is quite possible that Wohlfahrtia brunnipalpis Macq. is a synonym of 

 W. {Agria) argentea Macq. {Hist. nat. des lies Canaries, ii. 3, Dipt. p. 113 (1840) ), 

 but the description of the latter is not sufficiently precise to warrant a definite 

 decision as to this. Wohlfahrtia, {Aqria) argentifrons (Schin.) Br. and v. Berg 

 {Denkschr. Math.-Natiirw. CI. K. A/iad. Wiss. Bd. Ivi. p. 123 (Wien, 1889)), a 

 nomen nudum, is in all probability a second synonym of the species under 

 consideration. 



Genus WOHLFAHRTIODES ViUen. 

 Wohlfahrtiodes nuda Villen. 



(Deutscli. Em. Zcitschr., Jahrg. 1910. p. \bi (I'JIO).) 



Two ? ? from the southern portion of the Oued Mya, Algerian Sahara, 4. v. 

 1912 (Dr. E. J. 0. Hartert and C. Hilgert). 



The female of this species is as yet undescribed ; in this sex the dorsal surface 

 of the abdomen is entirely without spots, though when viewed at a low angle from
