A NEW CULEX, CULEX VOMERIFER, FROM PANAMA 
(DIPT., CULICID^E) 
By W. H. W. Komp 1 
Incidental to other duties in connection with malaria in- 
vestigations in the plantations of the United Fruit Com- 
pany at Almirante, Panama, the writer made collections of 
the local Culicidse as time permitted. Among the many rare 
and beautiful forms taken a new species of Culex was 
found. It is a Mochlostyrax, belonging to the section 
Chceroporpa, and like most of this group, is a small brown 
unmarked mosquito, not to be differentiated in any way 
from dozens of other species of the same group. Nothing is 
known of the life-history or of the immature stages. The 
description follows : 
Culex vomerifer sp. nov. 
Female : Unknown. 
Male : A small brown Culex, with rather wide pale bands 
at the bases of the abdominal segments. Legs all black. 
Palpi with the last two joints exceeding the proboscis, and 
clothed with rather long stiff hairs. Terminalia of male : 
Side-piece rather conically produced, bearing a lobe. Outer 
lobe undivided, bearing the following appendages : the most 
mesial is a long simple filament with a sharply recurved 
terminal hook. Then in order are a small flattened filament 
about two-thirds the length of the preceding hooked fila- 
ment. Next in order is a long, sharply acuminate filament, 
bent at nearly a right angle at one-half its length ; this fila- 
ment is laterally expanded at the bend, with the edges of 
the expansion directed inwards, forming a cup-shaped hol- 
low in the angle of the filament. Next in order is a flattened 
filament, just exceeding the bend of the long preceding fila-
