with a row of longer hairs, not conspicuous. Sternal plates 

 uncovered. 



Legs weakly bristled ; mid-tibia at last fourth with one small 

 bristle on inner side and one on outer front; on the outer hind 

 are two small bristles. 



Wing with first posterior cell narrowly open almost in the 

 apex, the third vein bearing nine or ten setules at base, its 

 last segment bulging forward in and beyond the middle, then 

 curving backward; fourth vein with a broadly rounded double 

 curve, near tip becoming almost parallel with third ; no costal 

 spine. 



As far as can be judged from a female, the genus is somewhat 

 allied to Cordylobia, but differs in having the arista not plumose, 

 etc. I can find no genus of testaceous flies with an arista like 

 the one here described. The three specimens examined vary in 

 regard to the third pair of anterior acrostichals, which when 

 present stand just in front of the suture; one specimen has 

 them present, one absent, and in the third a single bristle is 

 present, its mate absent. This character is generally of impor- 

 tance, as Villeneuve has used it to separate his Xanthocallipho- 

 rinae (his Testaceae sens, str.) from Eucalliphorinae (Calliphora 

 etc.). 2 



Female. — Wholly light yellow, including tarsi, except a trace 

 of brownish on the anterior part of the thoracic dorsum. Front 

 0.32 of the head width. Wings subhyaline with yellow veins. 

 There are numerous short, evenly placed black hairs, not only 

 on the front, face, and bucca (suggesting the specific name), 

 but also on the femora and whole abdomen, and even interspersed 

 with the bristles on the mesonotum and scutellum. 



Length, 6.3 millimeters. 



Described from three female specimens reared at Los Banos, 

 Laguna Province, Luzon, from the hoof of the water buffalo.
