Genus Culex. 
383 
broad white proboscis band extends from near the base to the middle ; 
legs fuscouSj fore femora sparsely decorated with scattered white scales, 
with a narrow white band a little before the apex; tibiae speckled white 
externally, uniformly coloured inside ; knees white; fore and mid tarsi 
with the first three, and the hinder with four, or all the joints with 
basal white bands; metatarsi distinctly shorter than tibiae. Abdomen 
dark fuscous, with coffee-coloured scales above and narrow whitish bands; 
greyish below. 
Length. —4*5 to 5 mm. 
Habitat .—Chaco in Formosa, Argentina.” 
Note. —In some respects this might be the C. taeniorhynchus , 
Wiedemann, but as I have seen no banded-proboscis forms of 
Culex from lower south than British Guiana, except Panoplites 
titillans and Taeniorhynchus fasciolatus, I cannot possibly say. 
I believe, however, that taeniorhynchus, which is so common at 
New Amsterdam, will be found to occur farther into South 
America. Dr. Lutz has sent me two specimens which he 
considers C. conjinnis, but I have been unable to satisfactorily 
determine them. I fancy from the description it is a taenio¬ 
rhynchus allied to* T. fasciolatus. 
[3/3. Proboscis unhanded. 
8. Legs basally banded. 
In this section will be seen a number of species of more or 
less different appearance; two main types, however, will be 
noticeable, namely a dark coloured group with white banding, 
Nos. 1 to 6, and those in which the basal leg banding is pale 
creamy and fainter, and which in many respects are scarcely 
separable from the next section, in which the banding is apical 
and basal.
