 the abdomen is dorsally banded with white.

Original Description of Aedes pertinax: 



$. Head with a triangular yellow area in the centre, made up of yellow hairs and 

 narrow curved scales, some rather broad, flattened ones at the sides, sides and back 

 of the head black, with many upright forked scales and hairs; antennae dark brown, 

 with silvery hairs on the joints; palpi and proboscis black, speckled with silvery 

 hairs. Clypeus dark brown. Prothoracic lobes black, with many long black hairs. 

 Mesothorax black, sparingly covered with very small narrow curved dark brown 

 scales, a narrow line of brilliant golden scales in the middle line extending to the 

 posterior quarter (in some specimens this line is ill-defined, in others broad and 

 conspicuous), a few long hairs near the posterior border and in front of the wing 

 insertions. Scutellum dark brown, with many long black hairs. Pleura grayish, 

 with patches of silvery scales and hairs. Abdomen, upper surface black, with mod- 

 erate basal bands of yellow scales, and with large lateral areas of silvery ones, two 

 small circular areas of golden scales in the centre of each segment. A few long 

 white hairs along the apical border of each segment. Venter almost entirely white, 

 with creamy scales, a few black scales near the apical borders of the segments. 

 Wings, extremities of the long veins with long narrow scales and short broad ones, 

 upper forked cell longer, but about as broad as the lower, its stem half its length; 

 the stem of the lower forked cell nearly as long as the cell. The posterior cross 

 vein half its own length behind the mid cross vein. Halteres with pale stems and 

 knobs. Legs black, unhanded, femora and tibiae with many yellow scales beneath, 

 fewer in the metatarsi and tarsi ; knee spot small. Ungues all equal and uniserrate, 

 the tooth large. Length, 4 mm. 



(^. Head, yellow area in the centre more extensive, broad, flat, yellow scales 

 abundant; palpi black, terminal joints slightly inflated, a little longer than the 

 proboscis; both terminal joints and apex of the antepenultimate densely covered with 

 long hairs, some very stout ones at the apices of the joints. Mesothorax with the 

 band of golden scales conspicuous. Terminal clasp segment slender, curved, slightly 

 swollen in the middle, apical spine blunt, about one-flfth length of limb. Basal clasp 

 segment with a large apical lobe; claspette a well-developed lobe near the base, 

 covered with short spines (no long ones present). Harpes, bases villous with fine 

 hairs, at the apex of each a recurved sickle-like portion. Harpagones deeply in- 

 fuscated, with a strong recurved spine on each. Unci membranous, separated, each 

 terminating in a point. Setaceous lobes pyramidal, with about ten strong carved 

 spines along the internal borders only. Ungues of the fore and mid legs unequal, 

 the larger claw with two teeth, the smaller with one. Ungues of the hind legs equal 

 and uniserrate. Length 4 mm. 



Notes on the adult Larva. Head broadly elliptical, long diameter transverse, 

 deeply infuscated. Antenna subcylindrical, with a slight curve inwards, infuscated 

 uniformly. Apex with four short spines, one much longer than the others. Surface 

 with scattered large chitinous spines; the upper surface has in addition several 

 longitudinal rows of minute spines running the whole length of the shaft, the points 

 of these spines directed inwards. Tuft below the middle of about eight short hairs 

 not reaching to the apex of the shaft. Upper and lower epistomal hairs single, a 

 small compound hair on the inner side of these, anteantennal hair tuft of 7-8 

 divisions. Mentum triangular, with about 30 small teeth. Thorax and abdomen 

 sparingly covered with fine setae. Two large hairs on each side of the first abdominal 

 segment, a single large one on all the others. Comb of about ten scales in a single 

 curved row, each scale with a strong apical spine and a number of fine setae on each
