Gregor), Los Baiios, Mount Maquiling, Tacloban, and Puerto 

 Princesa (Baker). This species was described recently from 

 southern India. The male may be mistaken for a small specimen 

 of Musca sorbens, but the thoracic stripes are well separated, 

 and the median pair are always very narrow in front of the 

 suture ; this character is extremely constant in both sexes. The 

 abdomen of the female is reddish brown with dark stripes and 



Musca bakeri sp. nov. 



Male.— Fourteen specimens from Los Baiios, Mount Maqui- 

 ling, Mount Banahao, and Zamboanga (Baker) ; from Culasi, 

 Panay, and Batbatan (McGregor) ; and from Alabang (Mitz- 

 main). Average length of specimens, 8.5 millimeters. Frons 

 very narrow, about one-fifteenth width of eye; eyes bare and 

 almost meeting; frontal stripe a narrow black line; parafron- 

 talia and cheeks silvery gray; antennae and palpi black; pro- 

 boscis normal. 



Thorax bluish gray with four broad, black, well-separated 

 stripes. The middle pair extend to the anterior margin of the 

 thorax, are not interrupted at the suture, and are distinctly 

 wider behind it ; the outer pair are broad, somewhat triangular 

 in front of the suture, and extend without interruption to the 

 margins of the scutellum. They are wider than the presutural 

 portion of the inner pair, and converge toward them. The 

 scutellum is yellowish, and the median dark band is often con- 

 stricted in the middle, forming two spots. 



Abdomen with apparent first segment black, but in two spec- 

 imens only the anterior part is black with a broad median 

 stripe, and in a third the majority of the segment is black 

 including the median stripe, the remaining narrow basal strip 

 is dark brown. In spite of these marked differences I have no 

 hesitation m saying that these three specimens are identical 

 with the more-typical forms. Apparent second segment either 

 light or dark brown (the latter in the majority of the speci- 

 mens), with a broad black median stripe and a narrow, black, 

 anterior band extending the length of the middle third of the 

 segment, and a large light silvery yellow admedian spot or 

 patch, and silvery yellow patches at the extreme edges of the 

 tergite; apparent third segment very similar, except that the 

 marginal patch is larger and between it and the admedian spot 

 there is a broad, triangular, clove brown stripe, and in many
