and very remote. Mandible quadrangular, in outline an oblique parallelogram, 

 a rather large patch of spines at base ; two filaments before tip from a distinct 

 notch: an outer row of cilia from a collar; eight filaments and three plumose 

 hairs on outer edge, rather close to collar; a long stout spine beyond; dentition 

 of four teeth on a process, first and third longer; a stout tooth before, a broad 

 filament within and a short furcate tooth at base; process below furcate, with 

 hair patches; five long hairs within; basal angle rounded; a row of long hairs 

 at base. Maxilla irregularly hemispherical, divided by an oblique suture ; inner 

 half covered with numerous thick short tufts at ends of stout papillae ; a tuft of 

 hair at tip ; outer half with two filaments next the suture preceded by an oblique 

 band of hair ; a stout spine on other side ; palpus short, slightly constricted cen- 

 trally, with four minute apical digits. Thorax rounded, wider than long, robust ; 

 hairs abundant, short, the subdorsal prothoracic ones single. Abdomen stout, 

 the posterior segments more elongate ; hairs short, the lateral hairs multiple on 

 first two segments, triple on third, double on fourth to sixth. Tracheal tubes 

 broad, band-shaped. Air-tube moderately stout, tapered outwardly, about three 

 and a half times as long as wide ; pecten reaching nearly halfway, the teeth 

 evenly and closely set, followed by a multiple hair-tuft; single tooth a long spine 

 with stout base, a single stout tooth and several small ones near base, the other 

 side with many small spinules. Lateral comb of eighth segment of about 

 eighteen scales in a triangular patch ; single scale elliptical, with a long stout 

 spinule at tip, the sides fringed with very short ones. Anal segment about as 

 long as wide, ringed by the plate ; dorsal tuft a brush and hair on either side ; 

 a single lateral hair; ventral brush well developed, confined to barred area, of 

 short tufts posteriorly situated. Anal gills rather short. 



The larvae live in temporary ground-pools of fresh rain-water. The speci- 

 mens were all found early in spring, but it seems probable that there may be 

 later broods.

Aedes mitchellce varies in coloration of the imago in a similar manner to 

 A. sollicitans. It much resembles this species and the dorsal stripe of the 

 abdomen is widened quadrately on the segments in the same way; this dorsal 

 stripe and the abdominal basal bands may be pale ocherous or they may be 

 nearly pure white, like the lateral spots.
