notum and the hind margin of the sciitellum are whitish-sealed; 

 pleura with patches of white scales ; abdomen black-scaled above, with 

 rather narrow white basal bands, black and white-banded beneath; 

 the wing- veins are clothed with long and narrow dusky scales; legs 

 black, the knees white, involving both ends of the joints; the front 

 legs with base and apex of the first tarsal joint and the base of the 

 second white-ringed; middle legs with the base and apex of the first 

 tarsal joint narrowly white-ringed, base and apex of the second joint 

 still more narrowly so, the base of the third joint narrowly ringed; 

 hind legs with the last tarsal joint entirely white, the remaining 

 ones broadly white-ringed at base and apex; front and middle tarsal 

 claws toothed, the hind ones simple. Length, 4 mm. 



In the male the palpi are long, but do not attain the apex of the 

 proboscis by about one-fourth its length, sparsely hairy, black-scaled 

 without annulations; the head is densely whitish-scaled; the meso- 

 thoracic markings are similar to those of the female, but the white 

 scaling is heavier; the antescutellar bare space is surrounded by 

 white scales, which are poorly indicated in the female ; abdomen black- 

 scaled above, with basal white bands, black and white-banded beneath. 

 Length, 4 mm. 



Ten specimens from Cordoba, Mexico, and Almolova, in the State 

 of Oaxaca, Mexico, bred from larva' in holes or hollows in bowlders 

 in stream beds. (F. Knab.) 



Type.— Cat, No. 11963, U.S.N.M. . 



This species is closely related to Aedes atropalpus Coquillett, but 

 differs in the coloration of the thoracic markings. 



AEDES CUNEATUS, new species. 



Female. — Proboscis rather long, black-scaled; palpi entirely black- 

 scaled; occiput pale yellowish-scaled, with a brown spot at each side; 

 mesonotum deep brown-scaled, with slight luster, and with two nar- 

 row pale yellowish subdorsal stripes; these stripes are thickened 

 along the median portion and become much narrowed on the poste- 

 rior third, reaching the scutellum outwardly of the antescutellar bare 

 space; they have a more or less distinct brassy luster; there are a few 

 of these yellowish scales along the sides of the antescutellar bare 

 space and the mid-lobe of the scutellum is clothed with similar scales; 

 abdomen black-scaled above, without bronzy luster, with cream-white 

 lateral basal segmental triangular patches; beneath cream-white 

 scaled, with apical black segmental bands; wings with dark narrow 

 scales along the veins; legs black-scaled, with bronzy luster; femora
