Studies on Tipulidae Il. 239 
P. 161, line 13 from bottom, strike out the word not. A rather 
important oversight of mine, 
P. 162. Brachypremna. 
A renewed visit to Berlin enabled me to describe the new 
Brachypremnae, mentioned by me in the Berl. Ent. Z. 1886, p. 161. 
— The generic characters, as given by me, answer very well for all 
these species; only in B. unicolor the praefurca is a little longer 
than usual and it is the third, rather than the second vein, which 
is in a line with it. The species from Surinam is undoubtedly B. 
dispellens, which oceurs in the United States. The four species 
hitherto described may be grouped as follows: 
Legs brownish (without any white) . . . wnicolor 0. 8. 
Legs brown, the root of the tibiae white . breviventris Wied. 
Femora brown, tibiae and tarsi white . . dispellens Wk. 
Femora brown, white at the tip, tibiae and tarsi white, but 
tibiae with a broad brown ring. . . pictipes O. 8. 
Brachypremna pictipesn. sp. ©. 
Front and vertex brownish, paler in the middle; antennae 
brownish, two basal joints yellow; rostrum yellowish above, brown 
below; palpi brown at base and tip, but yellow in the middle. Ground 
color of the thorax brownish-yellow; collar with a short double lon- 
gitudinal streak in the middle and a lateral brown spot in each side; 
mesonotum with a double brown intermediate stripe and short broad 
lateral stripes; metanotum pale, with three brown stripes; some brown 
spots on the pleurae. Abdomen brown above, with a very faint lon- 
gitudinal stripe on the basal segments; venter yellowish, with a 
brown streak in the middle of each segment, forming an interrupted 
longitudinal stripe; male genitals small, yellowish. Halteres brownish, 
paler at base. Femora brownish, the tip yellowish-white for about 
11/2 mm.; tibiae and tarsi yellowish-white, except a brown ring on 
the tibiae, about 3 mm. broad, placed at about 11/2 mm. from the 
knee, the interval being white. Wings with a uniform pale brownish 
tinge, the stigma but slightly darker; venation like that of B. bre- 
viventris Wied. Length 16—18 mm. 
Hab. Cassapava, Brazil (Sellow). A single male in the Berlin 
Museum. Resembles B. dispellens, but will be easily distinguished 
by the white tip of the femora, the different shape of the interme- 
diate thoracie stripes etc. 
Brachypremna unicolor n. sp. Ö. 
Reddish-yellow; front and vertex with traces of golden-sericeous- 
ness; nasus and tip of the palpi brownish; antennae yellowish, but
