A very obscure species, unless carefully examined, when the 
peculiar palpi at once separate it. I have been unable to 
distinguish the female in this collection. 
Genus TAENIORHYNCHUS. Arribalzaga (1899). 
Dipt. Argent., 47 (1899), Arribalzaga (mod. Theobald); Mono. Culicid. II., 
190 (1901); IV., 483 (1907), Theobald. 
Fourteen species at least come in this genus which are tabu¬ 
lated here. Six other species have been described as Taenio- 
rhynchus , but the descriptions are not sufficiently definite to say 
whether they are not, and they are placed at the end of the 
table as doubtful. 
I have recently seen a paper by Giles * on this genus.
