AUSTRO-M AL AYAN DIPTERA 471 



posteriorly by the fourth vein ; on the proximal side, its boun- 

 dary does not quite reach the middle of the last section of the 

 fourth vein. 



Hah. Kandari, Celebes, April 1874 {Beccari). Six females. 



NB. Hitherto the genus Euxesta was represented by species 

 from America only. E. prima is very like the North-American 

 species of the genus in its general appearance and answers the 

 description of the generic characters as given in the Beri. En- 

 tom. Zeitschr. 1867 , p. 297 , and in the Monographs of the 

 North Amer. Dipt. Ill, p. 153 ; only the front is a little more 

 convex and the face less excavated than in E. notala Wied. The 

 venation and coloration of the wings is very Hke 1. c. Tab. IX, 

 f. 10, only the apical spot fully reaches the fourth vein, but is 

 less broad ; the spot under the stigma is smaller. 



Rhadinomyia orientalis Schiner, Novara etc. 290 ! (Java). 



Three specimens ; top of Mt. Pangerango in Java, 1874 (Bee- 

 cari). 



Add to Schiner's description a narrow brown crossband star- 

 ting from the first longitudinal vein and running across the 

 proximal end of the submarginai cell to the proximal end of 

 the discal. 1 failed to notice in Vienna, whether Schiner's types 

 have that crossband. The genus belongs, I believe to the Uli- 

 dina, but the posterior angle of the anal cell is not drawn out 

 in a point. 



Platysloma punctiplena Walk. J. Pr. Lin. Soc. V, 268! (Ce- 

 lebes). 



Syn. Platystoma stellata Wk. 1. c. I, 32 (Malacca) ! 



E»latystoma atoinaria Wk. 1. c IV, 148 (Celebes) '. 

 IPlatystoma parvula Schiner, Nov. etc 286 (Batavia) ! 



Three specimens; Kandari, Celebes, April 1874 {Beccari). 



PL parvula Schin., which I saw in Vienna, seems to be the 

 same species, some discrepancies of the description notwith- 

 standing.
