AUSTRO-MALAYAN DIPTERA 421 



with a brown apical margin. Long. corp. 7-8 mm. (without the 

 ovipositor). 



Proboscis and palpi tawny; face pale yellowish-gray (some- 

 what injured in the specimen); front and vertex (9) black, 

 except a narrow stripe above the antennae , which is sil- 

 very ; basal joints of the antennae yellowish-tawny, very short ; 

 third joint also small , black ; the black arista , under a strong 

 lens, appears finely pubescent. Thorax tawny ; the dorsum opa- 

 que, without any apparent stripes ; pleurae a little paler, nearly 

 opaque, except a shining space above the middle coxae. Legs 

 yellowish-tawny, tibiae brownish, tarsi brown. Halteres tawny. 

 Abdomen brownish-tawny, hind margins of segments faintly 

 brownish. Wings with a slight yellowish tinge. A brown cross- 

 band issues from the dark brown stigma, runs across the mar- 

 ginal cell and fills out the proximal end of the submarginai, 

 where it does not cross the third vein; a moderately broad 

 apical margin begins immediately beyond the stigma, is broadest 

 at the intersection of the veins and has an indentation within 

 each of the cells which it crosses; becoming narrower poste- 

 riorly, it partly fills out third posterior cell, and coalesces with 

 a brown cloud on the distal crossveins of the discal cell. (In 

 other words, the brown crossband of the wings is interrupted 

 by the whole breadth of the first posterior cell and becomes 

 confluent with the apical brown border of the wing by means 

 of the third posterior cell ; it does not encroach upon the fourth 

 posterior cell). 



Hab. M.t. Singalang (Sumatra), July 1878; Beccavi ; one 

 female. 



NB. This species has the appearance and coloring of a Leptis. 

 I place it in Chryswpila on account of the anal cell being closed 

 some distance from the margin. But the palpi are broad and 

 flattened, almost spatulate; the face is not as concave as in 

 Chrysopila ; nor does the silky pubescence , which characterizes 

 the latter genus, exist here. But Leptis ferruginosa Wied. placed 

 in the genus Chrysopila by Schiner, can only artificially find a 

 place in it, and the genus Heliomyia estabhshed for it by Do-
