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 f ortiinata Walk. (J. Pr. Lin. See. IV, 137; Celebes), 

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

 A Single specimen. 



Rhynchomyia in die a Rond. (Ann. Mus, Civ. Gen. VII, 424; 

 Borneo). Two Specimens. 



Sarcophaga brevis Wk. and sericeonitens Wk.^ so deter- 

 mined by the author. 



Sciömyzidae. 



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

 and as many feraales, 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. III, 59, attributes this character to the females also. Nor 

 do my females have the obhque posterior crossvein, mentioned by 

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

 which I have from Sumatra (0. S. Enumer. QZ) 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. 

 Robineau 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 trän- 

 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 sufßcient plastic dififerences 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. $ Q. Front reddish with hlack 

 Orbits; thorax brown, 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.
