rest, 16 seems a close relative of C. imitator, being also very 
greenish in general colour. The proboscis is rather long and 
downwardly directed, as in Uranotaenia.” 
The greenish colour does not appear in the dead specimen 
sent. 
A-fresh g and @ were received later somewhat larger in 
size (4 mm.). 
CULEX SCHOLASTICUS. Theobald. 
(Mono. Culicid. II., p. 120, 1901.) 
Additional localities.—Trinidad (C. H. Hewlett); British 
Guiana (Dr. Low); Calliagua, St. Vincent, two ¢’s from crab- 
holes with Deinocerites (Dr. Low). 
Notes.—The British Guiana specimens have the posterior 
cross-vein nearer the mid than the West Indian, and the lateral 
spots more of a yellow tint than creamy white, as seen in the 
West Indian specimens. 
CULEX PIPIENS. Linnaeus. 
(Mono. Culicid. II., p. 132, 1901.) 
Additional localities. —Madeira (Funchal, 1,800 feet, and 
Quinta Val); Teneriffe (La Laguna and Santa Cruz de 
Santiago), April and March; Algeria (Dr. Billet). 
CULEX FLAVIPES. Macquart. 
(Mono, Culicid. II., p. 149, 1901.) 
Additional localities—Trinidad (C. H. Hewlett); George- 
town, British Guiana (Dr. Low). 
Notes.—Variation of the stem of the first fork-cell is very 
marked in the Trinidad specimens ; one 9 has the stem half the 
length of the cell ; others only one-third of the length. Another 
colour variation is seen in one @, which has two pale scaled 
round spots on the mesonotum and some pale scales on its 
anterior margin. This probably forms a distinct variety— 
var. biocellatus. 
The Trinidad specimens have also a very variable stem to the 
first fork-cell, some one-third, others one-fourth the length of 
the cell.
