AEDE8 HIRSTJTEKON 743 



mens from JSTanoose Bay. This species is inseparable from A'edes hirsuteron, 

 either by the coloration of the adults, or male genitalic characters. The larvae, 

 too, are similar, but differ in the head-hairs. This, together with the different 

 distribution, causes us to hold the species separate, at least until the receipt of 

 fresh material.

Obiginal Description of Ctjlex hirsuteron : 



Thorax brown, with scattered creamy scales (a dark median stripe when de- 

 nuded). Abdomen deep brown with basal bands of white scales, except on the last 

 two segments, which have a basal patch of white scales on each side. Ungues of 

 2 all uniserrated, simple. 



$. Head dark brown, densely covered with creamy curved scales in the middle and 

 with scattered upright forked ones, sides of the head with a small patch of almost 

 black flat scales; antennae nearly brown, with pale pubescence, the first two basal 

 joints being clear testaceous, the basal one having a few pale scales upon it on the 

 inner side; palpi covered with brown to almost black scales; proboscis very dark 

 brown, faintly testaceous at the base; clypeus deep testaceous; eyes black, in some 

 with gold and silver reflections. 



Thorax brown, with scattered curved creamy scales, when denuded showing a 

 dark stripe in the middle; scutellum paler brown, with a few curved creamy scales 

 and bright brown bristles; metanotum deep chestnut-brown, with more or less 

 purplish reflections; pleurae dark testaceous-brown, with patches of creamy- white 

 scales. 



Abdomen covered with deep brown scales, with a purplish reflection under the 

 microscope, with a basal band of white scales to each segment, except the last two, 

 which have a basal patch of white scales on each side; posterior borders with pale 

 hairs, but brown in some lights; on the venter the abdomen is paler brown, with 

 scattered creamy-white scales. 



Legs brown, unhanded; coxae chestnut-brown, with a few white scales; femora 

 ochraceous, with scattered dusky-brown scales, but with white scales beneath, the 

 rest of the legs brown; ungues of the fore, mid and hind legs equal, thick, uniser- 

 rated. In some specimens the legs are paler brown than in others, and there is a 

 pale knee spot on the hind legs in one of the series. 



Wings with long brown scales, testaceous at the root, rather more densely scaled 

 than usual in the genus Gulex; first sub-marginal cell very little longer and narrower 

 than the second posterior cell, its stem slightly shorter than the fork; the base of 

 the second posterior cell a little nearer the base of the wing than that of the first 

 sub-marginal cell, its stem a little shorter than the cell; posterior cross-vein more 

 than its own length distant from the mid cross-vein, the latter longer than the 

 supernumerary cross-vein. Halteres ochraceous. 



Length. — 3 to 3.5 mm.
