basal third, longer than the proboscis by the last joint 
and nearly half the penultimate joint, the last joint taper- 
ing to a point, just a little longer than the penultimate 
joint ; clothed on each side of the last two joints with moderatey 
long but scanty dark brown hairs, which also exist at the apex 
of the ante-penultimate joint ; proboscis deep ochraceous, 
swollen towards the apical end, covered with deep purplish-brown 
scales ; apex testaceous, sharply acuminate. Abdomen narrow, 
covered with brown scales, deep purplish-brown to almost black 
in some specimens, with basal white bands, which on the last few 
segments spread out laterally ; venter with grey or dull white 
scales, clothed above and laterally with numerous golden-brown 
hairs. Wings with the bases of the fork-cells nearly level ; the 
first sub-marginal cell from one and a-half to two and a half times 
as long as the stem ; stem of the second posterior cell about as 
long as the cell ; posterior cross-vein about twice its own length 
distant from the mid cross-vein. Legs rather more ochraceous 
than in the 2 ; fore and mid ungues unequal, dark brown to 
black ; in the fore legs both are toothed, the larger one having a 
long blunt tooth about the middle, the smaller a sharp-pointed 
one towards the base ; in the mid legs the ungues are very similar,

The " House Mosquito " ; man's greatest enemy ; it is purely 
nocturnal in habit ; it has a wide distribution in the world, as- 
sociated with the human race everywhere except in very cold 
latitudes ; breeds in stagnant water, in tanks, and even in cess- 
pits, and occasionally in watercourses up to a mile distant irom 
habitations. Oviposits in a large boat-shaped raft ; the eggs are 
white when freshly laid, but change to dark brown or black in 
a few hours even if kept in absolute darkness ; the eggs are laid 
as a rule between 6 and 8 p.m. 
This mosquito is the cause of untold misery to man, and the 
domesticated animals ; is the intermediary host for a number of 
parasites, perhaps the most important being Filaria of man and 
the dog. It will live in confinement, fed on banana or dates up 
to two months.
