9 . Head brown, clothed with upright, rather broad white 
scales in front and on the occiput, similarly formed black ones at 
the sides, and a tuft of white hairs projecting forwards ; antennae 
pale brown, wdth pale pubescence, basal joint bright brown, with 
white scales, which also extend on to the next few joints ; palpi 
black-scaled, apical joint yellowish-white, and the apices of the 
two preceding also banded white, the bands being narrow; 
clypeus pale brown ; proboscis thin, black, pale at the tip, as 
long as the palpi. 
Thorax brown, with rather slaty and testaceous tints and 
a dusky median line, with numerous scattered, creamy-yellow, thin, 
curved scales and pale hairs; scutelluui dark, with pale creamy 
scales almost white ; metanotum chestnut-brown ; pleurae de?p 
brown, with a few ashy-grey patches. In denuded specimens 
there may sometimes be detected live rather darker lines on the 
thorax. 
Abdomen black, with long golden hairs over the segments. 
Legs with the femora and tibiae brown, spotted and mottled 
with yellow scales; in the fore legs the joints are broadly banded 
with yellow, the bands involving both sides 'of the joints, in the 
mid- and hind-legs these bands are not so marked, and only now 
and then partially spread on to the bases of the joints, the 
major part of the bands being apical. Ungues equal and simple. 
Wings with four large and two small black spots on the 
costa, the two median large ones the longest; on the first long 
vein there is a black mark under the apical spot and two under 
the next costal spot and two under the next large one, a single 
one under the fourth ; a black patch at the tip of each vein, and 
at the fork of the first sub marginal cell. On the stem of the first 
sub-marginal cell, just at the fork and 
under the third costal spot, is a small 
patch, another on each side of the mid 
cross-Vein on the third vein, another

Anopheles costaiis, Loew (9). the folk of the fouith ^ e in, and 
9 d one on each branch of the second 
posterior cell, and another past the cross-veins ; two on the stem 
of the fifth, with three on its upper branch and three on the 
sixth ; first sub-marginal cell longer but little narrower than 
the second posterior cell, its base if anything a little nearer the 
aoex of the wing than that of the second posterior, its stem 
about two-thirds the length of the cell; stem of the second 
posterior cell about equal in length to the cell; mid cross-vein
