ABT. 6 NOTES ON ORIENTAL SAPROMYZID FLIES MALLOCH 5 



shallow depressions at bases of the very fine sparse hairs which occur 

 over the entire surface. Hypopygium as Figures 9 and 10. Inner 

 cross vein of wing a little beyond middle of discal cell; marginal 

 cell not as wide as submarginal at apex, the second vein not very 

 abruptly bent forward at apex. 



Length, 4 mm. 



Type. — Male, allotype., and 14 paratypes, Mount Maquiling, Luzon 

 (C. F. Baker). 



Type.— C2it. No. 41084, U.S.N.M. 



Two of the paratypes are immature and appear to the naked eye 

 almo,st uniform fulvous in color, but there is a very evident violet- 

 blue tinge on the scutellum when they are viewed from behind. 



ACELYPHUS REPLETUS, new species 



Male and female. — A darker species than the preceding one, more 

 purplish than violet blue, with the same colored palpi. 



Head similar to politus. A very striking character apart from 

 the double punctuation of the scutellum, is the presence of dense 

 erect miscroscopic pile on the mesonotum. Similar pile occurs on 

 the mesonotum and entire scutellum of stigmaticus^ but there is no 

 indication of such pile on the scutellum, and onlj'^ a vestige of it 

 on the extreme anterior margin of mesonotum, in politus. Inner 

 cross vein beyond middle of discal cell; second vein rather abruptly 

 bent forward at apex. 



Length, 4 mm. 



Type. — Female, Wai Lima, Sumatra, 1912 (Karny and Siebers), 

 in author's collection ; allotype.) male, and three paratypes., Singapore, 

 Straits Settlements (C. F. Baker), in United States National 

 Museum. 



Allotype.— M^lIq, Cat. No. 41087, U.S.N.M. 



There i^ a possibility, but no certainty, that some of the smaller 

 species of this group described as belonging to Celyphus may be 

 referable here. 



ACELYPHUS STIGMATICUS (Hendel) 



Spaniocelyphus stigmaticus Hendel, Suppl. Ent., No. 3, 1914, p. 93. 



This species has occurred only in Formosa up to the present, but 

 it may be found in other sections of the Orient. It was described 

 when the genus Spaniocelyphus wa^ erected, but scutatus Wiedemann 

 was selected as the genotype. 



IDIOCELYPHUS, new genus 



General characters. — Head similar to that of Spaniocelyphus, the 

 vertex rather sharp, with four bristles and a pair of small, but dis- 

 tinct, postverticals ; oscellars lacking; antennae as in Spaniocelyphus ;
