AUSTRO-MALAYAN DIPTERA 405 



NB. The genus Teucholahis is abundantly represented in 

 North and South- America , but hitherto has not been known 

 to occur anywhere else. T. hicolor reproduces exactly the cha- 

 racteristics of the genus, the somewhat prolonged rostrum, the 

 hairy legs , the peculiar venation ; even the structure of the 

 forceps , as far as I can ascertain , seems to be the same as 

 that of the N. American T. complexa, which I have described 

 in the Monogr. N. Am. Dipt. IV, p. 129, Tab. Ill, f. 9.

 I saw a male and a female from Sula in the Brit. Mus. under 

 the above name. 



NB. In this species, the dx first joint of the flagellum have 

 each a single branch ; the branches are all of the same length, 

 except the first, which is a little shorter ; all are on the inner 

 side of the antenna ; the two first, are directed downwards, the 

 others horizontally inwards (supposing the antenna to be extend 

 horizontally forwards) ; the following joints (beginning with the 

 seventh of the flagellum) are without branches , (their number 

 cannot be stated, as the tips are broken off). The branches in
