Genus CELLIA Theobald. 
Type: pulcherrima Theob. The genitalia will probably prove 
similar to those of Anopheles. I have not seen them of either 
of the species recorded from North America, viz: argyrotarsis 
Desv., albipes Theob. 
Genus CYCLOLEPPTERON Theobald. 
Type: grabhamii Theob., the only species recorded from our 
region. The genitalia are unknown to me. 
Genus ARRIBALZAGIA Theobald. 
Type: maculipes Theob. This species is recorded from 
Trinidad and will doubtless be found in the southern portion of 
our region. The genitalia have not been examined. 
Genus PSOROPHORA Desvoidy. 
Type: ciliata Fab. We are credited with three species, viz: 
ciliata Fab., howardii Coq., scintillans Walk. The genitalia of 
ciliata have been figured by Dr. Felt. 
Genus MEGARHINUS Desvoidy. 
Type: hczmorrhoidalis Fab. We are credited with seven 
species, viz: rutilus Coq., portoricensis Von Rod., ferox Wied., 
grandiosus Will., h&morrhoidalis Fab., longipes Theob., separa- 
tus Arrib. Mr. Barber has made me a nice mount of the geni- 
talia of portoricensis, from which the characters given in the 
table were taken. 
Genus STEGOMYIA Theobald. 
Type: fasciata Fab. Besides this species, sexlineata Theob. 
may occur with us. The genitalia of fasciata are distinctive as 
may be inferred from the preceding table. 
Genus PNEUMACULEX, new genus. 
Type: signifer Coq. This species is peculiar in many ways 
and deserves a distinct generic appellation. The larva has be- 
sides the peculiar dorsal plate an enlargement of the tracheal 
tubes into a sort of bladder in the thorax, suggesting Corethra. 
In the cT genitalia the side pieces are conic, without apical lobe ; 
basal lobe small but bearing two stout setae; terminal clasp 
slender, enlarged a little outwardly with a multiple articulated 
tip. Harpes short, chitinous, concave, with trifid apex ; harpa- 
gones small, slender, chitinous, acute; another pair of appen- 
dages more basally placed, shorter than the harpagones, with 
a terminal hook; a median, divided, double-tipped membrane 
(unci?).
