vertical bristles and a pair of smaller outer diverging ones. Face 

 with a little grey shimmer viewed from certain directions ; pro- 

 boscis and palpi black. Antennae dull black ; from base of 2nd 

 joint to tip of 3rd, exactly equal to half the height of the eye; 

 2nd joint with a single bristle above ; arista very finely but not 

 shortly plumose above and below. Back of head black. 



Thorax. — Blackish with an aenous green tint and microscopic 

 pubescence. A row of four bristles near posterior margin ; 2 supra- 

 alar, 2 notopleura', 2 sternopleural bristles. Sides of thorax dull 

 black. Scutellum concolorous with thoracic dorsum ; two post- 

 basal bristles tov/ards sides ; a pair of converging apical ones. 



Abdomen. — Dull black, with a suspicion of a faint aenous green 

 tinge in certain lights ; a little shining towards the base at the 

 sides ; very shortly pubescent. Belly black. 



Legs. — Black, a row of bristly hairs below femora, remainder 

 of legs shortly pubescent, as are the femora also. 



Wings. — Pale but distinctly yellowish ; halteres black. 



Described irom '^ &&\ Rotung, 1400 ft., 25— 26-xii-ii, and 

 Sadiya, 23-xi-ii. 



This must be near Meijere's aenea, described from East 

 Austria but not known to Schiner. It is rather larger, and seems 

 to have affinities with more than one of Meijere's lately described 

 species from Java. 



Lonchaea, sp. 



Two specimens in very indifferent condition represent a 

 second species, noticeable by the reddish yellow antennae. 

 Slightly but appreciably larger than L. niontana. From Kobo, 

 400 ft., 3-xii-ii, and Dibrugarh, 17 — 19-xi-ii. 



Lauxania flavicornis, mihi, sp. nov. 



Assam. Long. 3 mm. 



Head. — Frons shining black, the sides parallel, distinctly but 

 not greatly more than one-third the width of the head. A median 

 velvet-black stripe from vertex, gradually narrowing on reaching 

 base of antennae ; the very distinct but small yellow ocelli placed 

 on this stripe well below the vertex. Antennae orange-yellow, 

 normally shaped, the 2nd with a few bristly hairs at tip, 3rd very 

 elongate cylindrical, nearly twice as long as first two joints 

 together, black, with a long white arista which is yellowish at its 

 base and microscopically plumose. Two pairs of dorso-frontal 

 bristles, the upper pair just below the ocelli, situated half-way 

 between the velvet-stripe and the eye margin, the lower pair half- 

 way between the upper pair and the base of the antennae, set 

 rather more widely apart. 



A pair of long, converging vertical bristles placed midway 

 between the velvet-stripe and the eye margin ; a pair of similar 

 ones outside of these, and a pair of very small ones immediatel}^ 

 behind middle of vertex. Occiput black, a little behind vertical
