212 ALLIED MUSCID AND MLSCELLANEOUS FLIES 



MUSCA ENTENIATA BiGOT. 



This species of house-Hy has a distribution somewhat similar 

 to the last species and like it has a marked resemblance to 

 M. domestica as Bigot's (1887) description indicates: " Front tres 

 etroit, les yeux, toutefois, separes. Antennis et palpes noirs ; face 

 et joues blanches ; thorax noir avec trois larges bandes longitudi- 

 nales grises ; flancs grisatres, ecusson noir avec deux bandes 

 semblables; cuillerons et balanciers d'un jaunatre tres pale; 

 abdomen fauve, avec une bande dorsale noire et quelques reflets 

 blancs ; pieds noirs ; ailes hyalines ; cinquieme nervure longi- 

 tudinal (Rondin) coudee suivant un angle legerement arrondi, 

 ensuite un peu concave; deuxieme transversale (I'extreme) presque 

 perpendiculaire, legerement bisinueuse, soudee a la cinquieme 

 longitudinale, a egale distance du coude et de la premiere nervure 

 transversale (rinterne)." 



M. enteniata measures 4 to 5 mm. in length. The British 

 Museum collection contains specimens sent by Major F. Smith 

 from Benares, with these notes : " Bred from human ordure ; 

 hospital ward fly; at an enteric stuol ; bred from cow dung fuel 

 cakes." I have received specimens from Suez and Aden, and it is 

 recorded as breeding in human excrement in Khartoum (Balfour, 

 1908) and in stable refuse, as also are M. domestica and M. corvina. 

 It will be seen, therefore, that its breeding habits are very similar 

 to those of M. domestica and the sub-species determinata. It is 

 interesting to note the choice of cow dung as a breeding place, 

 especially in conjunction with the economic status of the cow in 

 India. 



Muse A VETUST18SIMA WaLK. 



This is a common species in Australia and can be readily 

 distinguished from M. domestica by the silvery white-thoracic 

 stripes. Cleland (1912), who reprints Walker's description of the 

 species, writes of it as follows : " This fly is essentially an out-of- 

 door species. Very rarely indeed is it found within the house 

 and only occasionally in out-houses with open doors and windows. 

 When found in these situations it is usually attracted by some
