A Monograph of Culicidae. 
Habitat. —Adelaide (75), Queensland (Bancroft) (71), King 
George’s Sound, Western Australia (Masters). 
Time of capture .—Adelaide in November, December, and 
January; Queensland in August. 
Observations .—This sub-species, like the type, is evidently a 
household pest, those received having been taken indoors; the 
Adelaide specimens were captured on the windows of the museum. 
The two thoracic lines should readily identify this sub-species, 
which seems to be very common in the southern part of South 
Australia, and probably all over the continent. (Some of these 
specimens were sent by Dr. Bancroft under the Culex nigrothorax , 
Macq. 1) 
Sub-species b, SJcusii. Giles. 
Culex sp. near ciliaris (?). Skuse. 
Head brown, ornamented as in the type; antennae brown, 
basal joint and basal half of the second joint bright reddish- 
yellow. 
Thorax brown, clothed with golden-yellow curved scales, bare 
in front of the scutellum, traversed by bare lines often very 
indistinct, these seem to be four in number; in front is a median 
dark line not bare, running partly down the thorax ; this has a 
double series of black bristles and ends at the bare patch in 
front of the scutellum; there are also two lateral lines of 
bristles, which run back to the scutellum as in C. linealis; 
scutellum dark ochraceous, with golden-yellow scales in the 
middle and on each lateral lobe and bordered with golden-yellow 
bristles, brown in some lights ; metanotum light to dark brown ; 
pleurae pale testaceous, with small indistinct patches of pale, 
almost white scales, pleurae evidently variable in colour. 
Abdomen clothed with purplish-brown to purplish-black 
scales, the segments with basal bands of creamy-white to yellow 
scales, semicircular in form; ventrally the abdomen is covered 
with pale yellowish scales. 
Legs with apical femoral and tibial spots. Wings with the 
scales very dark, with a purplish hue. Halteres ochraceous, 
fuscous towards the knob. 
Length —of $ 5 to 5*5 mm.; of ? 5 to 5*8 mm. 
Habitat. —Australia generally. Skuse says widespread in 
Australia. 
Observations. —This sub-specie.s runs so closely into the type 
that I feel rather doubtful in separating it. All the specimens
