XVII. Culex rima. Nov. sp. 
(Fig. ii, PI. II) 
Thorax deep-brown. Abdomen deep-brown, with metallic-bronze and violet reflections, 
white, apical, lateral spots and grey venter. Legs deep-brown, unhanded. Wings with rather 
broad scales like C. atratus, Theo. Ungues small, curved, equal, and simple. 
9 . Head dark-brown, with narrow, curved, dull-grey scales and numerous short, upright, 
black ones ; clypeus (b) black, with a transverse sulcus ; antennae brown, with reddish-brown basal 
joint ; proboscis black, testaceous at the apex ; palpi rather thick, black. 
Thorax deep-brown, with very minute, narrow curved, dull-brown scales and long black, 
backwardly-projecting bristles ; scutellum deep chestnut-brown in the middle, greyish apically, 
with narrow dull-brown curved scales and black border-bristles ; metanotum deep-brown ; 
pleurae greyish or greyish-brown. 
Abdomen bronzy-black, with deep bronzy-green and deep-violet reflections when held in 
different lights, the four posterior segments with four distinct, white, apical spots ; posterior border- 
bristles dull-brown, short ; apex pubescent. Legs deep-brown ; the coxae very pallid, and also 
the venter of the femora ; the metatarsi and tarsi with somewhat dull, ochraceous reflections 
ventrally. Ungues small, equal, and simple. 
Wings (Fig. i la, PL II) densely scaled towards their apices with rather short, thick, brown 
scales (V) (as in C. atratus Theo.) ; fork-cells rather short, first submarginal cell longer and 
narrower than the second posterior cell, their bases not nearly level, that of the former, nearer 
the base of the wing ; stem of the first submarginal equal to about half the length of the 
cell ; stem of the second posterior as long as the cell ; posterior cross-vein slightly curved in the 
middle, nearly three times its own length distant from the mid cross-vein ; fringe brown, very 
dark at the apex of the wing. 
Halteres with ochraceous stem and fuscous knob. 
Length. — 2"8 mm. 
Habitat. — Old Calabar. 
Time of capture. — April. 
Observations. — Described from three 9 's. A small species with very distinct abdominal 
ornamentation. In two specimens the thorax is paler brown. It is closely related to the little 
black Culex I call Culex atratus, common in Jamaica. The peculiar wing scales and general 
facies of these two species will necessitate their removal from Culex, but I am waiting for more 
material as I have only received one damaged $ (C. atratus) of this group. 
XVIII. Culex invidiosus. Nov. sp. 
(Fig. 12, PL II) 
Head deep-brown with greyish sheen, seen in some lights ; thorax deep chestnut-brown ; 
abdomen blackish-brown, unhanded and unspotted ; pleurae paler brown ; legs deep-brown, coxae 
and bases of femora pale. 
9 . Head deep-brown, almost black, covered with dull ochraceous grey narrow curved 
scales over the occiput, black upright-forked ones, and small flat dull white lateral ones, a narrow, 
rather indistinct grey border round the eyes ; clypeus deep chestnut-brown ; proboscis deep 
blackish-brown ; palpi short, densely black scaled ; antennae brown, basal joint testaceous in the 
centre.
