146 Memoirs of the Indian Museum. [Vot. Ill, 



Head entirely yellow, of the same shape as in the two preceding, but the frons a 

 little prominent and the cheeks more broad ; antennae the same, the arista shortly 

 pilose ; palpi little developed ; proboscis of usual shape ; bristles long, black. 



Thorax black, with scarce grey pollen, more shining on the pleura ; humeri 

 reddish, and the pleural sutures also ; all the bristles are long and black ; the scp. 

 black, but weak. Scutellum triangular, flattened, entirely of a red colour ; it bears 

 4 bristles, the apical pair not much weaker than the basal. Squamulae whitish ; 

 haltères yellow. Abdomen entirely black and shining ; lateral and apical bristles 

 well-developed, black ; ovipositor as long as in fossata. I^egs black, the fore coxae 

 also blackish ; fore tibiae entirely yellow, the others towards the end ; tarsi wholly 

 yellow. 



Wings more elongate and narrow, the first 4 longitudinal veins being therefore 

 not so apart from each other, the 3rd and 4th being parallel outwards ; cross-veins 

 more remote, the small cross- vein being much beyond the middle of the discal cell, 

 but separated from the hind cross-vein by a distance equal to the length of the latter. 

 Base, alula and axillar lobe hyaline ; costal cell hyaline to the stigma, which is wholly 

 black. The rest of the wing is black, with the following hyaline indentations : two 

 are placed towards the middle of the fore margin, and are of triangular shape, with the 

 vertex on the third vein and the base on the costa, which is of a yellow colour at this 

 point ; the first begins just after the stigma, the second is very close to it and a little 

 narrower ; the brown streak dividing these two indentations is placed symmetrically 

 above the small cross- vein. Two other, large and narrow approximate indentations 

 are at the hind margin, just after the tip of the wing. The first is curved as an arch, 

 being parallel to the wing border ; it begins very narrowly in the middle of the sub- 

 marginal cell towards its apex and runs, becoming always more broad, to the hind 

 margin, which it reaches at the end of the 4th vein ; the second is parallel to the first, 

 but a little smaller and shorter, beginning at the third vein and ending at the hind 

 border in the fore half of the second posterior cell. There is a fifth hyaline streak in the 

 posterior part of the third posterior cell, which separates, as in the preceding two 

 species, the brown streak along the sixth vein from the black central part of the wing. 

 There is also a hyaline vertical discal streak running towards the end of the discal cell, 

 just below the small cross- vein ; but this seems to be variable, being wanting in one 

 specimen. 



Two female specimens; one typical from Kurseong, 5000 ft., E. Himalayas, 

 8-vii-o8 m\^) ] the other, badly preserved, from the same locality {m~) , but of an 

 older coUection ; this is without the hyaline discal streak, but otherwise similar. 



' 24. Spheniscomyia, nom. nov. • .' 



Spheniscus , Becker, Mitteil. Zoolog. Mus. Berlin, iv, 138 [Sphaeniscus] (1908). 

 Easily distinguished by the bare third vein, the well-developed costal bristle, 

 the approximate cross- veins, by only 2 pairs of lower or., by the black colour of the 

 body and by the pattern of wing, which is very like that of some species of Urophora. 

 Characteristic also is the absence of bristles on the abdomen.
