APPENDIX 
XL Culex maculicrures. (Theobald) 
{Mono. Culicidae, Vol. I) 
Four specimens (two $ 's and two 9 's) of this large brown species, bred from larvae taken at 
Bonny, and hatched during June. The 9 measures between six and seven mm. ; the thorax is 
dark-brown, with reddish-brown scales, and shows two prominent pale spots, with a pale line 
running from each backwards, and sometimes one or two pale and indistinct spots in front. The 
abdominal segments have narrow, apical, dull-yellow borders. The legs are brown and unhanded, 
but the femora and tibiae have a row of small yellow spots on one side. 
This mosquito has a wide distribution in Africa, and Dr. Bancroft has recently sent it 
from Australia (Queensland). 
XII. Culex metallicus. Theobald 
{Mono, culicidae. Vol. I) 
(Fig. 14, PI. Ill) 
A number of this very distinct and pretty species, both $ 's and 9 's, taken during July, in 
the Bush opposite St. Stephen's Cathedral, Bonny. 
It can at once be told by the thorax being silvery on the front half, brown on the posterior 
half, and by the more or less brilliant metallic violet abdomen, which is unhanded, as also are the 
legs, the femora being silvery at the base. 
I have not seen this species from any other district in Africa, but I have the remains of a 
species very similar to it from Siam. ' It is only provisionally placed in Culex. 
XIII. Culex prulna. Nov sp. 
(Fig. 6, PI. I, and Fig. 7, PL II) 
Thorax covered with frosty-grey scales, with traces of two parallel darker lines ; abdomen 
with the fifth to eighth segments with basal lateral white spots, almost forming bands, bases of the 
other segments slightly paler, in the $ with more or less distinct banding. Legs brown, unhanded. 
9 . Head brown, clothed with hoary, narrow curved scales, and numerous ochraceous 
upright-forked ones ; eves black ; clypeus, palpi, and proboscis deep-brown ; antennae brown, basal 
joint paler. 
Thorax shiny black, covered with thin, hair-like, curved hoary scales, and showing traces 
of two dark parallel bands on the denuded surface ; scutellum with narrow curved hoary scales ; 
metanotum testaceous and ochraceous ; pleurae dark-brown above, ochraceous below. Abdomen 
(Fig. 6, PI. I) dark-brown, almost black; the fifth to eighth segments with basal white lateral 
patches, which are most pronounced on the sixth, seventh, and eighth segments ; the abdomen 
shows violet reflections ; border-bristles pale. Legs brown, unhanded, ventral surface of the 
femora nearly white ; ungues equal and simple. 
Wings (Fig. Jci, PI. II) with pale-brown, typical Culex scales ; fork-cells rather long and 
narrow, the first submarginal longer, but no narrower than the second posterior cell, its base 
nearer the base of the wing than that of the latter ; its stem about one-fourth the length of the 
cell. Stem of the second posterior cell about one-half the length of the cell ; supernumerary 
cross-vein long and sloping, forming a very acute angle with the mid cross-vein ; posterior cross- 
vein longer than the mid, and about one-and-a-half times its own length distant from it. Halteres 
ochraceous. 
Length. — 5 to 5'2 mm.
