A Monograph of Culicidae. 
ungues small, equal and simple, whilst those of the fore and mid 
legs are unequal and uniserrate. 
Things with brown veins and scales; first sub-marginal cell a 
little longer and slightly narrower than the second posterior cell, 
their bases about level, both cells fairly long ; stem of the former 
about equal to half the length of the cell, of the latter to about 
two-thirds of its length; posterior cross-vein more than its own 
length distant from the mid cross-vein, the costa, sub-costal and 
first long vein with rather broad flat scales, the so-called sixth 
and eighth veins of Austen’s pamphlet (the incrassations) very 
distinct. Halteres with pale stem and fuscous knob. 
Length. —5*5 mm. 
Habitat. —Salisbury, Mashonaland (Marshall) (79). 
Time of capture. —-February. 
Observations. —Very similar in general appearance to 
C. plumosus, but differs in the ungues of the 9 being simple 
instead of serrated, and in the q ungues being uniserrated, 
whereas in plumosus the larger unguis of the fore and mid legs 
is biserrated; the proboscis band is also less marked, and the 
$ palpi differ. A single £ and 9 only sent by Mr. Marshall. 
Although the £ presents certain differences in appearance. 
I think it must belong to this species. 
25. Culex albirostris. Macquart. 
(Dipt. Exotica, Supp. iv. p. 10.) 
“ Proboscis white, except at the base and tip, where it is black. 
Abdomen with the hinder borders of the segments white, tarsi blackish, 
with a white ring at the base of each joint. 
Lenyth. —2 lines 9 . 
Habitat. —New Zealand.” 
Note. —No banded-proboscis forms have been sent from New 
Zealand. I am not sure, from the description of this species, 
whether the abdomen is basally or apically banded. It may 
possibly be the Culex annulirostris of Skuse. 
26. Culex (?) coxfinnis. Arribalzaga. 
(Dipt. Argentina, La Plata, p. 49 (1891).) 
“Very like Taeniorhynchus taeniorhynchus, Arribalzaga, but of 
smaller size and darker colour, while the band on the proboscis is 
broader, but differs especially in the form of the wing scales. The
