238 . C. R. Osten Sacken: Diptera 



Sapromyzidae. 



Sapromyza. There are nine or ten species in the coUection, 

 none of which can be referred to the existing descriptions of asiatic 

 Sapromyzae. One of them has the abdomen colored like Minettia 

 signata v. d. Wulp, Sumatra Exp. 52, Tab. III, f. 12. only the 

 penultimate abdominal segment has a round brown spot on the underside, 

 on each side of the brown stripes represented on the figure. 



Celyphus levis v. d. Wulp, Sumatra Exp. 53. I refer the 

 specimens to this species, on account of their smooth surface, although 

 their abdomen is metallic green, and not black, the antennae nearly 

 brown etc. 



Sepsidae. 



Sepsis revocans Walk. J. Pr. Lin. Soc IV. 163 (Celebes). 

 The specimens were so determined by Mr. Walker, and agree with 

 bis unmeaning description. 



Sepsis sp. Two specimens, determined S. testacea Wk. J. Pr. 

 L. Soc, IV, 163 (Celebes), by Mr. Walker, but certainly dififerent from 

 it. The species is remarkable for its very bristly legs; the male has 

 teeth on the underside of the front femora. 



Sepsis spec. named hasifera by Mr. Walker (J. Pr. L. Soc. III, 

 125; Arn) is most certainly a different species. 



Ephydridae. 



Paralimna sp. Agrees with the description of Notiphila 

 chinensis Schiner, Nov. (which, is a Paralimna), except that the knees 

 and the extreme tips of the tibiae are reddish, a character not men- 

 tioned in that description ; the gray design on the first abdominal 

 segment also seems to be a little different. — Two specimens. 



Dry xo Kob. D. 



This genus was established by Robineau Desvoidy (Myod. p. 787) 

 for D. lispoidea R. D. (Sumatra). In 1867 Mr. Jaennicke (Neue 

 Exot. Dipt., p. 59 Tab. I, f. 14) published a good description, with 

 excellent figures of the genus Cyphops^ which is hardly different from 

 Dryxo, although the species, C. fasciatus (Sumatra), is not the same 

 as D. lispoidea. I possess two species- from the Philippine Islands, 

 which enable me to give a fuller description of the genus. I will base 

 this description upon one of the species {D. digna), that I possess
