252 A Monograph of Culieidae. 
the apical joint minute, rounded, the penultimate joint large, 
truncated apically ; in the ¢ the two apical joints and the apex 
of the antepenultimate swollen, the apical one large and clavate, 
hair-tufts small. Thorax with narrow-curved scales, and also 
the scutellum. Wings with the fork-cell rather small, with 
mottled scales on the veins, the scales on the major portions of 
the veins rather broad and with crenulated edges. Larvae with 
short thick siphons. 
This genus differs from Culex and Grabhamia in having flat 
scales over the head—not regular and closely applied to the head 
as in Stegomyia, from which it also differs in having clavate g 
antennae and no flat scales on the scutellum. The ragged 
appearance of the head is very marked, otherwise it comes very 
near Grabhamia. 
ACARTOMYIA ZAMMITII. n. sp. 
Head ochraceous yellow at the sides, white in the middle ; 
proboscis ochraceous black at the base and apex. Thorax brown, 
ornamented with bright yellowish brown and pale creamy curved 
scales, ornamentation much as in G. dorsalis ; metanotum pale 
brown, with a dark centre. Abdomen deep blackish-brown, with 
basal white bands, which in the fifth and sixth segments spread 
out laterally ; a few median pale scales on the last two segments, 
venter all creamy. Legs with apical and basal pale bands and 
with the last hind tarsal white. Wings with mottled brown 
and grey scales. Female ungues 1—-1. 1—1. 1—1.; in the ¢ 
2—1. 1—1. 1—1. 
9. Head (fig. 132, a) deep brown, with loose flat white scales 
in the middle, a few narrow-curved ones in front, and some irregular

loose flat ochraceous yellow scales and a few narrow-curved ones 
around the eyes, forked scales white, yellowish and black at the 
sides; clypeus deep brown; proboscis deep ochraceous, black 
scaled at the base and on the apex; palpi deep brown, with 
white scaled apex, and a white band lower down; antennae 
brown, basal joint deep brown, with small white flat scales, the 
next few joints pale, the second one swollen, and with a few 
small flat white scales. 
Thorax deep brown, ornamented with narrow-curved golden- 
brown and narrow-curved pale creamy scales, the latter in front 
and forming two lines on the dorsum, somewhat expanded about
