A Monograph of Culicidae. 
I have not sufficient evidence, however, to enter fully into the 
habits of the latter genus at present. 
Steg’Omyia larvae. —The genus Stegomyia is formed on 
certain characters best seen in S. ( C .) fasciata (p. 289). With 
regard to their larval habits I can record very little at present. 
According to Major Ross’s report, larvae of the taeniatus type 
were observed in hollows and in wells. Captain James’s Tiger 
mosquitoes I feel sure are Stegomyias, although the habits differ 
so widely from those observed on the West Coast of Africa. 
Stegcmyia fasciata has been sent by Captain James, and is 
probably the species referred to in his paper. 
Corethra larvae. —The beautiful transparent larvae of the 
Coretkra may be found in all kinds of watery places; it matters 
not to these crystalline creatures whether the water is shallow or 
deep, clear or cloudy, stagnant or running, but it is especially 
in clear water that they occur. Their transparency, even when 
mature, evidently protects them from fish, for we find them in 
pieces of water and rivers teeming with fish, contrary to those of 
the Anopheles and Culex. 
Meinert states that they may be found in pools half covered 
by weeds, in marl pits or small lakes, and he also found them in 
a dark forest hole, and in a small deep marshy hole without a 
trace of vegetation. Gotze found the larvae first in a w^ell, the 
surface of which was covered with duckweed, and observed that 
the larvae can live for hours in the strongest vinegar without 
being affected. 
Moelllonyx larvae. —The only note I know regarding the 
larvae of Mochlonyx is that of Meinert’s, who merely mentions, 
after describing the larvae, that they may be found in ponds, &c., 
in fields, and woods, and that they are especially found in ditches 
where the water is clear and the current nil, and also in water on 
inundated wood bottoms, filled with fallen beech leaves and 
traversed by a deeper ditch, and in patches of water overgrown 
with iris, and often in large troops with Culex larvae. 
Aedes larvae and allies. —With regard to Aedes we know 
nothing. Osten-Sacken found them with Culex larvae, but 
merely states that they resemble those of Culex but are 
smaller.
