from the Philippine Islands. 193 



the species, the contrast in the coloring, between the proximal and 

 distal half of the wing, the latter being more brown than the former, 

 is not mentioned at all in the description. Ten specimens. 



Lucilia fortunata Walk. (J. Pr. Lin. Soc IV, 137; Celebes). 

 So determined by Mr. Walker. I believe it is L. nosocomiorimi Dol. 

 A single specimen. 



Bhynchomyia indlca Rond. (Ann. Mus. Civ. Gen. VII, 424; 

 Borneo). Two Specimens. 



Sarcophaga hrevis Wk. and sericeonitens^'k., so deter- 

 mined by the author. 



Sciomyzidae. 



Sepedon javensis R. Desv. Myod. 677. I have four males 

 and as many females, which agree exactly with an original colored 

 drawing of this species by Doleschall, that I possess. The males alone 

 have the front tarsi enlarged, and I do not understand why Macquart, 

 D. E. Suppl. Ill, 59, attributes this character to the females also. Nor 

 do my females have the oblique posterior crossvein, mentioned by 

 Macquart, 1. c. On comparing these specimens with a single male, 

 which I have from Sumatra (0. S. Enumer. 6d) I perceive that the 

 latter has the distal third of the front and middle femora deep-black 

 and the middle tibiae of the same color, the halteres whitish ; while the 

 specimens from the Philippines have the extreme tips only of the fe- 

 mora darker and the middle tibiae reddish; the halteres more yellow. 

 Robinean Desvoidy's description („Tarses et tibias noirs") rather applies 

 to the specimen from Sumatra. Mr. v. d. Wulp, whom I consulted on 

 the subject, kindly informed me, that both forms occur among the nu- 

 merous specimens in the Leiden Museum; that there were also tran- 

 sitions between them; that the same form had been received from diffe- 

 rent islands and different forms from the same island. For this reason 

 he is of the opinion that until sufficient plastic differences are disco- 

 vered, it is safer to treat these forms as mere varieties. I cannot but 

 concur with this opinion. 



Psilidae. 



Chyliza selecta n. sp. $5. Front reddish tvith black 

 orbits; thorax broivn, humeri, longitudinal stripe on the pleurae, 

 and scutellum brownish-yellow; prevailing color of the legs yello- 

 wish; apical third of the wings infuscated. Length 5—6 mm.
