of the female as 18-jointed, the 8rd to the 18th joints 
having a single row of branches on the inner side, and 
the ovipositor unusually long and robust. 
The Baron Osten-Sacken, who has carefully examined 
the type of G. subfasciata in the British Museum, assures 
me of its distinction from G. Wakefieldit.

[Geranomyia, Osten-Sacken, Cat. Western Dipt. p. 196.) 
Timnobia affinis. Corpus elongatum, gracile. Caput 
parvum oculis magnis; proboscide gracili, cylindrica, 
porrecta, fere longitudine corporis; palpis haud con- 
Spicuis ; antenne breves, graciles, ad basin proboscidis 
insert, thorace multo breviores; maris 14-articulate, 
articulis 2 basalibus majoribus, reliquis equalibus 
oblongo-ovatis; foem. 12 vel 13-articulate brevissime, 
(articulis 2 vel 8 basalibus incrassatis, reliquis 10 sensim 
ad apicem attenuatis) articulis 2 terminalibus  setis 
6 longissimis, penicillum efformantibus, instructis. 
Prothorax in collum gracile productus. Ale iridescentes, 
haud pilose, venis in alis masculinis fere ut in Limnobia 
xanthoptera, Meig. (Schilling Beitr. Dipt. t. 2, fig. 1), 
dispositis; in foeminis cellulis marginalibus cum sub- 
marginali omnino coalitis (vena longitudinali illas in 
mare dividente omnino obliterata) in mare etiam nubila 
stigmaticalis exstat, locum vene transverse rudi- 
mentalis indicante. 
Obs. Ex omnibus Tipulideis adhue cognitis differt 
proboscide longissima, inde affinitatem cum Culicideis 
possidere videtur. 
As the species upon which I proposed this genus have 
afforded much discussion among dipterologists, I have 
thought it advisable to reproduce them verbatim below. 
These insects were three in number; two of them were 
from Bahia, in Brazil, communicated to me by the late J. 
Aspinall Turner, M.P.; they were a maleand a female, cor- 
responding in size, colour, and general appearance, pinned 
with the same small short kind of pin, and both having

stances I did not hesitate to regard them as the opposite
