band on segment three, which is well marked on the ventral 

 side of the tergite. Sternites dark orange. Wings with four 

 small bristles on the radial root vein, but as they are not in 

 very good preservation it is not possible to be sure of the 

 number; as some of them have certainly fallen off; vein R 4+5 

 with small bristles on its ventral side, extending well beyond 

 the radiomedial cross vein. Legs black. Squamae yellowish. 



Female. — Average length of two specimens, 7 millimeters. 

 Frons comparatively narrow, about half the width of the eye, 

 and narrowest at the vertex, the orbital margins converging 

 toward it. Frontal stripe about one-third the width of eye, 

 sides slightly convex. Farafrontals gray, each about one-third 

 the width of the frontal stripe and with a single row of small 

 bristles; parafacials and cheeks silvery gray, edges of episto- 

 mum black. Antennae, palps, and proboscis similar to those of 

 male. 



Thorax very similar to that of the male, presutural portion 

 of outer stripes broad and more convex externally. Scutellum 

 grayer at the sides than in the male. 



Abdomen with apparent first segment similar to that of the 

 male, but, if anything, the basal black band broader; apparent 

 second segment with a narrower median dark brown stripe, 

 the stripes adjacent to it and the marginal spots yellower, the 

 admedian brown stripes broader, more triangular in shape and 

 extending along the lower border, forming a posterior band 

 interrupted a little in the middle. Apparent third and fourth 

 segments similar, the admedian brown stripes narrower and 

 the basal band on segment three more complete. Sternites as 

 in the male. Legs and wing similar to those of the male. 



The four specimens were collected at Buitenzorg, Java, and 

 the types will eventually be returned to Mr. Illingworth, Hono- 

 lulu, the cotypes remaining in my collection for further study. 



I believe this is the species described by Stein, 1 without a 

 name, from Samarang and Batavia. He refers to it again 2 

 under the name Musca lusoria Wiedemann, noting that it has 

 small bristles all along the ventral side of vein R 4+B as in the 

 true lusoria. But, as Villeneuve has already pointed out, this 

 is not a character peculiar to lusoria but is common to many 

 of the species of this group. Stein's description agrees very
