AUSTRO-MALAYAN DIPTERA 465 



the antennae and the second pair of bristles is clothed with 

 scattered, minute hairs. This distribution of bristles is not that 

 of Trypeta. The face is very characteristic ; a large transverse 

 swelling a little below its middle , produces a very projecting 

 profile (see the figure 2 a in Walker, 1. c). The third antennal 

 joint of Xiria obliqua is a little shorter than that of X antica 

 (if rendered correctly in the figure 1. c. 2 c). The scutellum has 

 six bristles : six other strong macrochetae are inserted on each 

 side of the thoracic dorsum, and a weaker seventh bristle just 

 above each corner of the scutellum. I do not perceive any me- 

 sothoracic bristle on the pleurae nor a prothoracic one above 

 the front coxae ; both in the meaning of Loew , Monogr, etc. 

 Ill, 33. The costa and the first vein are rather densely hairy ; 

 the third vein is beset with scattered hairs , visible under a 

 strong lens; the fifth vein bears some strong hairs before the 

 crossveins, closing the basal cells. 



The ovipositor of X. violacea is described by Wiedemann as 

 « breit umgeschlagen », whatever that may mean.

D.^ Schiner's description agrees exactly with my specimen. 

 Doleschalls is too short for identification ; but I saw a type of 

 his in Vienna. The antennal arista is pubescent at the base only, 

 and DoleschalFs expression « seta piumosa » somewhat mislea- 

 ding. The species agrees with the characters of the genus, as 

 given by Loew in the Monogr. of N. Am. Dipt. Ill, 96. 



Stenopterina didyma n. sp. 9. Wings with a large apical 

 brown spot, and a brown, round spot on each of the two cross- 

 veins. Length 7 mm.
