AUSTRO-MALA YAN DIPTERA 491 



to me to be the same species, the differences in the length of 

 the ocular stalks and in the coloring notwithstanding. 



Diopsis sp. Java, {Beccari, 1875), two specimens. Also a Te- 

 leopsis, but certainly different from the preceding. The coloration 

 of the wings is exactly like that of D. atteìiuata. 



NB. It would be rash to describe the above two species as 

 new , without a critical revision of all the asiatic species of 

 Diopsis, that, from want of material, I am unable to attempt. 

 But what [ have seen in the collections which I have visited 

 has convinced me , that the species have been unnecessarily 

 multipHed. Some 14 or 15 species of Diopsis from the Eastern 

 Archipelago have been described , belonging in the group with 

 banded wings, besides four or five from other parts of southern 

 Asia ; two species from those regions are known, which have a 

 single apical spot ; and only one (D. Hearseyana Westw.) with 

 colorless v^ings ; twenty three asiatic species in all. 



Celyphus oblectus (Dalman) Wied. Auss. Zw. II, 601 (East- 

 Indies). 



A dozen specimens from Buitenzorg, Java (G. B. Ferrari 

 1875) and from Singapore. 



The Brit. Mus. possesses specimens from the Philippines, Hong 

 Kong and Calcutta. 



Celyphus scutatus Wied. Auss. Zw. II, 601 (East-Indies). 

 One specimen from Buitenzorg (Java), G. B. Ferrari. 



Celyphus levis v. d. Wulp, MSS. (Sumatra). 



Two specimens from Ajer Mantcior , Sumatra (Beccari, Aug. 

 1878). It resembles a specimen labelled C. fuscipes Macq. sent 

 by M.*" Bigot to the Museum in Vienna, but is much smoother 

 (less punctate) and more shining. I prefer to use the name 

 under which M.'' v. d. Wulp intends to describe it in a forth- 

 coming paper on the diptera of Sumatra.
