644 MOSQUITOES OF NOETH AMERICA 



Aedes epacUus is very closely allied to Aedes atropaJpus, but as the adults 

 differ in coloration we hold them separate. The larvae are closely similar and 

 the life-histories seem to be identical.

 ring near the middle, white; occiput with two patches of black ones on each side, 

 the upright forked ones black and whitish; first submarginal cell noticeably less than 

 twice as long as its petiole.

Original Description of T^eniorhynchus sierrensis: 



5. Head brown, a median line of white curved scales extending up between the 

 eyes, immediately followed laterally by a patch of flat brown scales, a narrow white 

 stripe laterad, followed by a brown stripe, narrow white line around the eyes, white 

 forked and curved scales on the occiput; the general effect is of two brown sub- 

 median spots, and the curved scales are confined to this comparatively narrow 

 median line; antennae brown, and while not really banded, giving the effect of white 

 bands, verticels brown, pubescence white, basal joint white scaled; palpi brown 

 with white tips, and a narrow light band about midway; proboscis dark brown; 

 clypeus brown; eyes brown. 



Thorax brown, with fine tomentum, resembling the " frost " on some Anophelina, 

 partly denuded, but sparsely covered with brown and white curved and spindle- 

 shaped scales, the white scales being apparently mostly on the outer parts of the 

 mesonotum, i. e., cephalad, on the sides, and a heavy median bunch Just in front of 

 the scutellum; prothoracic lobes brown, with white curved scales; scutellum brown, 

 such scales as remain are white curved and spatulate; pleura brown, with heavy 

 patches of broad white scales: metanotum brown, nude. 



Abdomen brown, with basal white lateral spots and basal white bands, thickened 

 on the median line, which do not always reach all the way across, and on the penulti- 

 mate segment is merely a median white spot; some segments also narrowly 

 apically banded, apical hairs brown ; ventrally mostly light scaled, and on the distal 

 segments arranged so as to form both basal and apical bands. 



Legs: coxae and trochanters brown, with light scales; femora dark, slightly 

 speckled with white scales, the dorsal sides the darker, but on the hind legs light 

 at the base; small white knee spot on all the legs, a little more pronounced on the 

 hind legs; tibiae dark, sometimes' a little speckled; metatarsi on all the legs with 

 basal and apical light spots, which are very faint, sometimes missing on the fore 

 legs and develop into well-marked basal and apical white bands on the hind legs; 

 the fore legs are of lighter brown and the banding often very faint or missing; 1st 

 and 2nd tarsal joints on the hind legs with apical white bands, on mid and fore legs 

 only the 1st tarsal have apical white spots, and in the fore leg they are very in- 

 distinct; remaining joints brown; ungues simple and equal. 



Wings covered with brown typical Twniorhynchus scales; 1st submarginal cell 

 nearly a half longer and a little narrower than the 2nd posterior, the stems nearly
