hairs of the abdomen paired and flattened ; on the anterior segments each 



hair is large and 4- to 7-branched, liairs becoming smaller and with fewer 



branches on the hinder segments. Comb of six or seven scales in a 

 curved row, the largest in the middle. Central scales joined by a thin 

 broad chitinous band, the upper and lower scales separate, base of each 

 scale oval, sides coarsely setose below, the apical free border with one 

 curved stout central spine and two to six much shorter lateral spines. Air 

 tube fusiform, inflated, deeply infuscated, devoid of hairs, about four times 

 as long as wide (at the base) ; pecten rows of four well-separated teeth in 

 each, a fifth small i)air at the extreme base in some specimens ] rows one- 

 quarter length of tube ; upper two pairs of teeth with two or three smaller 

 denticulations on the inner side, lower pairs with denticulations on both 

 sides. Band ringing the anal segment about as long as broad ; barred 

 area running along whole length of the band. Ventral tufts of 18-20 

 pairs. A pair of tufts and long simple setae dorsaily. Anal gills very 

 long, narrow, pointed, 2^2 times as long as the longest hairs of the ventral 

 brush. Pupa with short, stout siphons, 



Observatiojis. — Four living larvre of this handsome species were taken 

 from a temjjorary pool in a logwood thicket, about 5 3^ miles along the 

 Molynes Road, near Kingston, early in April, 1906. The larva is large 

 and stout, the head, which is much compressed anteroposteriorly, is set 

 at right angles to the thorax, and the large antenmie are carried almost 

 vertically downwards, giving the larva a peculiar a])pearance. The 

 description of the larva is drawn up from the larval skin casts, that of the 

 adult head, thorax and abdomen from the freshly-killed specimens. A 

 notable feature in the male is the thickly-scaled second antennal joint, 



Aedes auratus, no v. sp. — 9 • Head covered with narrow 

 curved yellow scales and hairs. Many forked upright yellow scales at the 

 back ; a few forked upright black scales and black hairs at the sides. 

 Antennse dark brown, joints with pale yellow hairs. Palpi black, speckled 

 with yellow scales. Proboscis black, with scattered yellow scales and 

 hairs, especially near the base. Clypeus black. Thorax rich golden 

 yellow. Frothoracic lobes with black hairs and yellow scales, Meso- 

 thorax densely covered with narrow curved golden-yellow scales in front, 

 somewhat more scantily at the back (scales of thorax darker in shade than 

 those on the head) ; on each side in front, near the middle line, there are 

 two small dark spots ; there is also a large dark area on each side reaching 

 from the prothoracic lobes to above the wing insertions, and extending
