AUSTRO-MALAYAN DIPTERA 419 



One 9, Borei Hum, New Guinea, Febr. 1875 (Beccavi). I 

 have no doubt that this is but a less dark variety of the same 

 species. The femora , and in part also , the tibiae , instead of 

 black, are yellowish rufous; the abdomen is only slightly in- 

 fuscated on the posterior margin of segments 2-5. The wings 

 agree exactly ; (there is a slight inaccuracy in the extent of the 

 brown design, as given in the figure ; the first submarginai cell 

 should be nearly filled out with brown ; the crossband should 

 be less pointed , broader , posteriorly). — It is not a true Sil- 

 vius, because the antennae have a different shape and the eyes 

 show a trace of a broad crossband, while the known species of 

 Silvius have greenish eyes, dotted with black. 



Haematopota irrorata Macq. D. E. 1, 1, 163; Tab. XIX, f. 3. (Java). 



Four 9. Mt. Singalang, Sumatra, July IS7S (Beccari). I de- 

 termine this species in agreement with M.^ Y. d. Wulp , who 

 showed me three , closely allied species from Sumatra, but 

 which could easily be distinguished by the arrangement of the 

 spots at the tip of the wing. Macquart's description shows 

 shght discrepancies. 



H. pungens Dol. (Java) may be the same species , but the 

 description is too incomplete. 



LEPTIDAE. 



Chrysopila ferruginosa Wied. (Leptis) Auss. Zw. I, 224 (Java). 



Eighteen c/^ 9 ; Ternate 1875 (Beccari). 



Four J'; Kandari, Celebes, April 1874 (id.). 



Two </, one 9 from Dorei Hum, N. Guinea 1875 (id.). 



The males from Ternate and New Guinea have brown inci- 

 sures on the abdominal segments, which the females have not. 

 The males from Celebes do not have these incisures. Are they 

 the same species ? Wiedemann describes a male , but does not 

 mention those incisures. Some specimens, especially those from 

 New Guinea have the distal half of the wings much more in- 

 fuscated.
