throughout their length, the first bearing only some bristles at the tip ; the posterior 

 cross-vein also bristly on the underside. 



It is very probable that the genus Themara of Walker is the same as the present, 

 as already suggested by Osten-Sacken (Ann. Mus. civ. Genova, xvi, 461, 1881). 

 From the Neotropical genus Blepharoneura , Loew, it differs in the waviness of the 

 second vein, in the pattern of the wings being not reticulate, in the scutellum bearing 

 only four bristles and in the sexual dimorphism of the head. The European Platy- 

 parea poeciloptera, vSchrank, shows some relation to this group. 



26. Acanthoneura? fuscipennis, Macquart. 

 (PI. ix, fig. 29.) 

 Macquart, Dipt. exot.,iii. 378 (221), pi. 30, f. 2 (1843) ; Enderlein, Zool. Jahrbuch., xxxi, 417 (1911). 



A middle-sized species, vv^ith luteous indentations on the wings, the last one of 

 the fore margin being whitish-hyaline like the single discal dot. 



I am very doubtful if the present species is the same as that of Macquart, both 

 figure and description being rather different; but I think that in this case Macquart' s 

 inaccuracy has been very great. The pattern of the wings of my species is exactly 

 the same as in Walker's Themara ampla (Proc. I^inn. Soc. i, pi. i, f. 5, 1856), and 

 I should take this species as a synonym if Osten-Sacken had not said that it is the 

 same as Achias horsfieldi , Westwood, in which the figure of the head is very different 

 from my male specimen. As shown, however, by Prof. Meijere (Tijdschr. v. Entom., 

 liv, 382) and by Dr. Enderlein (/. c, 415) the width of the head is very variable. 



Frons opaque, the vertex and the stripes on which are inserted the or. being 

 shining. All the bristles black. Abdomen shining black, the first four segments of 

 the male with the hind border yellow, in the female the first three only. The bristles 

 on the posterior cross-vein are very distinct; the tip of the wing is devoid of spots; 

 the narrow triangular indentation at the tip of the first vein and the round dot in 

 the first posterior cell are whitish hyaline, the other indentations being luteous 

 hyaline. 



Two damaged specimens from Sadiya, Assam, one (-^-g^-) labelled by Bigot as 

 Trypeta lineata 9 , n. sp., the other (-^-g^^) labelled by the same author as Eurosta 

 picta d , n. sp.; Macquart records the species from Bengal. 



Themara ampla was taken at Singapore. 



10. Phaeospila^ n. gen. 



This genus is easily distinguished from the allied Rioxa by its black body, strong 

 oc, pointed third antennal joint and by the very peculiar pattern of the hind border 

 of the wings. 



Head as broad as high, with narrow cheeks; eyes round; face concave, the 

 epistome a little prominent; antennae inserted on the middle of the eyes, the third 

 joint more than three times the second in length, very sharply pointed at the tip ; 

 arista densely but shortly plumose ; palpi bristly ; bristles of the head long but rather 

 weak, ail black; or. 2. 3; oc. very long, longer than the superior or.\ vt. 2, the inner
