23,4 Patton: New Oriental Species of the Genus Musca 329 



One of the widely distributed house flies of the Oriental 

 Region. 



As already pointed out, I have examined the type of Musca 

 vicina Macquart and find it is the species which is very like the 

 typical domestica, but differing in that the male has a much 

 narrower front — about half the width of the male of domestica, 

 I have also examined the types of flavinervis, -flavifacies, flavi- 

 pennis, and atrifrons, and note that they are this species. I hope 

 soon to have an opportunity of examining the type of biseta 

 Hough. The remaining synonyms are given with a mark of 

 interrogation before them, as I am unable to determine them 

 from the descriptions of their authors. Stein has several times 

 referred to this species of Musca, regarding it as a narrow- 

 fronted domestica. 



Musca nebnlo Fabricius. 



Musca determinata Walker (nee Patton).* 

 ? Musca multispina Awati. 



The other common house fly of the Oriental Region. 



Unfortunately, the type of this important fly has shared the 

 fate of the rest of the collection of Diptera belonging to Fabricius 

 at Kiel ; but, as Wiedemann examined this type when it was still 

 intact and redescribed it very fully, I have no hesitation in 

 accepting as final Major Austen's determination given me many 

 years ago. Wiedemann says : "Hinterleib gelblich durchschein- 

 end, in gewisser Richtung weisslich fast gewiirfelt, mit 

 schwarzer, den vierten Abschnitt nicht erreichender Strieme," 

 which agrees exactly with the characters of the abdomen of this 

 species. 



Musca yerburyi Patton.* 



Musca incerta Patton (nee Walker).* 



Common in southern India, Ceylon, and Burma. 



Shortly after describing this species under the name incerta, 

 I found that the name was preoccupied by Musca incerta Walker, 

 so I here take the opportunity of changing the name to yerburyi 

 in honor of Colonel Yerbury who has done so much to advance 

 our knowledge of the Oriental and, particularly, the Cingalese 

 species of the genus Musca. I have not seen this species in any 

 of the collections I examined in the continental museums. So 

 far, it is now known only from India.
