XXII. Aedes nigra. Theobald 
{Mono. Culicidae, Vol. II) 
Five 9 'sand one $ of this small dark Aedes only about 2mm. long. Taken at Old Calabar 
in April. It can readily be told by its black appearance, unhanded legs, abdomen, and absence of 
thoracic ornamentation. From the Uranotaenia it can at once be distinguished by the relative 
greater length of the fork-cells. 
Genus Uranotaenia. Arribalzaga ( 1 89 1 ) 
{Dipt. Argentina, p. 63, 1891) 
Palpi short in the $ and 9 as in Aedes, but the fork-cells are very small, especially the 
first submarginal fork-cell. There are always flat scales, usually brilliant in places on the meso- 
notum and on the scutellum, and the head is entirely covered with flat scales. Many of the species 
bite severely. The larvae are often brilliantly coloured with red, blue, and green, and seem to be 
intermediate between Anopheles and Culex in structure. 
XXIII. Uranotaenia domestica. Theobald 
{Mono. Culicidae, Vol. II) 
Two specimens of this beautiful Uranotaenia taken at Old Calabar at the Vice-Consulate, 
in April. One badly damaged. 
It can easily be identified by the bright, chestnut-brown thorax, with a small, silvery spot 
on each side in front, another on the roots of the wings, a bright, silver-scaled scutellum ; the 
abdomen is almost black, with white lateral spots, and the legs are black with a white spot at the 
apex of the tibiae and femora, and a silvery band near the apex of the hind femora. 
Length. — 4 mm. 
XXIV. Uranotaenia annulata. Theobald 
{Mono. Culicidae Vol. II) 
Three 9 's and three $ 's taken at Bonny in May. A very marked little Uranotaenia, 
with chestnut-brown mesothorax and sharply contrasted pale creamy pleurae and head, the latter 
having a dark median line. The abdomen is brown, and has apical grey or white bands. Legs 
brown ; the hind ones with the metatarsi and first two tarsi with apical white bands, and the 
last two joints pure white. 
XXV. Uranotaenia caeruleocephala. Theobald 
{Mono. Culicidae, Vol. II) 
Eight 9 's taken in April at Old Calabar. It is a beautiful little deep-brown species, 
easily identified by its sky-blue head. The legs and abdomen are unhanded. On the thorax may 
be seen a line of white scales at the sides, just in front of the wings. 
Length. — 2*5 mm.
