hyaline streak near the base of the marginal and submarginal cells. The second ray- 

 extends along the fourth vein to the tip of the wings, filling up the small cross-vein. 

 The third ray is separated at the base from the other two by the hyaline second basal 

 cell and extends to the hind margin along the fifth vein, filling up the whole of the 

 anal cell. The stigma is yellow. The costal ray shows 4 black dots along the costa, 

 the first after the end of the first vein, the second and third, one before and one 

 after the end of the second vein, the fourth at the tip of the third vein ; between the 

 three last spots are placed two hyaline streaks along the costa. The tips of the other 

 two rays are also spotted with brown but the apical spot of the third ray is placed 

 just at the end of the fifth vein, while that of the second is placed beneath, and there- 

 fore leaves the end of the fourth vein free. 



A single female specimen from the Dawna Hills, L. Burma, 2 — 3000 ft., 2 — 3-iii- 

 08 (-11-), collected by Dr. Annandale ; I take pleasure in naming this handsome and 

 distinct species in honour of the Superintendent of the Indian Museum .

Rob.-Desv. , Essai sur les Myodaires, 720, xiv (1830). 



The species of this genus show a short pilose arista, a head not widened below, 

 a scutellum with four bristles, a bristly third vein and the small cross-vein placed 

 after the middle of the discal cell. 



Head a little broader than high, not widened beneath , with the mouth-opening 

 small ; eyes very large and rounded ; face flat, the epistome not prominent ; frons 

 not or little prominent ; antennae inserted on the middle of the eyes, much shorter 

 than the face, the third joint being about twice as long as the second, rounded at the 

 tip , distinctly pubescent or bare ; arista shortly pilose or pubescent ; cheeks narrow 

 or broad ; oc. developed, but not strong; or. 2. 3, rarely i. 3; vt. strong, curved 

 backwards ; /)v^. parallel ; genal bristle well-developed; bristles of the occipital row 

 black ; palpi very broad, spatulate, almost bare ; proboscis short. 



Thoracic chaetotaxy complete ; scp. well-developed, black ; 2 mpl. ; pt. strong ; 

 4 scutellar bristles, the apicals shorter than the basais or of equal size, parallel or 

 a little diverging. Abdomen narrow, elongate, bristly on the sides and at the end ; 

 ovipositor short and broad, flattened, triangular. Front femora with a row of 5 — 6 

 bristles below ; middle tibiae with a spur ; hind tibiae with a row of short hairs. 



Wings broad and short, or narrow and elongate, with a small but distinct costal 

 bristle ; first vein short, ending much before the small cross-vein, but sometimes 

 very long ; 2nd, 3rd and 4th veins almost straight, wide apart from each other and 

 slightly diverging outwards in the broad winged species, in the narrow winged species 

 parallel; small cross- vein placed beyond the middle of the discal cell, often in the apical 

 third or fourth, long and oblique or short and perpendicular ; posterior cross- vein 

 long or short, parallel with the small, very close to the hind margin ; third vein bristly 

 from the base to the small cross-vein or a little beyond it ; inferior angle of the anal 

 cell drawn out into a long and very narrow point, which is equal in length to the 

 second basal cell.
