TAXONOMY OF 1 MUSCOIDEAN FLIES — TOWN SEND 1 23 



Distinguished from pilatei by the buccal being black, silvery gray 

 pollinose, not at all yellow. Second pair of ocellar bristles present 

 in female, not developed in male. 



Type.— Cat. No. 10,894, U. S. N. M. (Tennessee, Coll. Riley). 



Lucilia infuscata, sp. nov. 



Nine males, six females, Massachusetts, New Hampshire, Ohio, 

 Missouri. New Mexico, Arizona, and British Columbia. 



Two postacrostichal bristles. Male front very narrow, female 

 front two-sevenths of head width. Basal abdominal segment black 

 or purplish black in female, but no dark margins to second and third 

 segments. Male tegulse infuscate, female tegular more nearly white. 

 Palpi yellowish. Buccae, face, and front black. No second pair of 

 ocellar bristles. The female can.be told from female ccesar only by 

 narrower front and darker basal segment. 



Type.— Cat. No. 10,895, U. S. N. M. (Organ Mountains, New 

 Mex., on flowers of Lippia wrightii — Townsend). 



Lucilia oculata, sp. nov. 



Six males, two females, District of Columbia, Kentucky, North 

 Carolina, Mississippi, Kansas, and Cuba. 



Two postacrostichal bristles. Male front linear, eyes nearly con- 

 tiguous and approximated more anteriorly than in infuscata, with 

 larger front aspect than in that species. Female front one-fourth 

 of head width. Tegulse nearly white, only very faintly tinged with 

 yellowish. Antennae and face brownish yellow instead of black. 

 Basal abdominal segment quite black. Male shows no second pair 

 of ocellar bristles, but female has them developed. Otherwise like 

 infuscata. 



Type— -Cat. No. 10,896, U. S. N. M. (Cumberland Gap, Ky.— G.

PROTOPHORMIA, gen. nov. 



Hough characterizes Phormia as having the mesonotum "some- 

 what flattened caudad the transverse suture," as in ProtocaUiplwra. 

 This is a mistake. P. regina, which is the type of Phormia, does 

 not show this flattening at all. The species tcrrccnovce is not a 

 Phormia, but differs in possessing the same conspicuous flattening 

 seen in ProtocaUiplwra. The new genus Protophormia is herewith 

 proposed for its reception. The characters given by Hough for 

 Phormia (Ent. News, x, p. 66) all apply to P. regina except the 

 character of the flattened thorax. This flattening carries with it a 

 more or less complete abortion of the postacrostichal bristles except 

 the hindmost one of each row.
