apex, legs yellow; tips of the femora and of the tarsi brownish. 
Long. corp. about 7 mm. 
Head reddish-brown; proboseis rather long; antennae brown, 
yellowish at the base. Collare bright reddish-yellow; thoracie dor- 
sum of the same color, shining, with three large black spots, two 
of which on the sides, immediately in front of the suture; the third 
smaller, triangular, just behind the collare (the thoracie dorsum 
might as well be described as black, with a yellow stripe in the 
middle, forming a fork in front); behind the suture, the color is 
partly yellow, partly black (somewhat indistinet in the deseribed 
specimen, on account of the pin inserted here); scutellum and meta- 
thorax dark brown or black. Halteres with yellow knobs; stem 
brown. The abdomen (very much contracted in drying) seems to 
have been brown. Legs yellow, including the front coxae; hind coxae 
brownish. Tips of all the femora brownish; front tibiae and tarsi 
and tips of the other tibiae and tarsi, likewise brownish. Wings 
with a pale brown crossband reaching from the darker brown stigma, 
across the central crossveins, to the sixth vein; apex also brownish. 
Hab. Sula (Indo-Malay Archipelago); a single male. I preserve 
the name under which I found it in the British Museum. 
Teucholabis polita n. sp. ö. Black, thorax shining, wings 
with two brown crossbands and a brown apex. Long. corp. 2,5—3 mm. 
Head, rostrum and palpi black; antennae brown. Thorax black, 
dorsum shining; halteres brown, knobs yellow; abdomen, including 
genitals, blackish brown. Legs light brown, except coxae and proxi- 
mal two thirds of the femora, which are yellowish-tawny. Wings 
hyaline, with brown erossbands; the first between the base of the 
praefurca and the end of the seventh vein; the next between the 
stigma and the end of the sixth vein, covering the central crossveins; 
apex of the wing, as far as the distal end of the discal cell, brown; 
a faint pale brown spot in the proximal angle of the basal cells.

I have shown (l. c.) that this genus is a close relative to Teu- 
cholabis, the presence of two submarginal cells nothwithstanding. 
In fact the usual single submarginal cell is divided in two by a 
supernumerary crossvein, which, being sometimes placed obliquely,
