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; be- 

 neath cream-white scaled, with apical black segmental bands; wings with dark 

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

 trally and basally white; tibiae of all the legs whitish-scaled on the inner side; 

 tarsi not ringed; claws all toothed. Length, 4.5 mm. 



In the male the palpi somewhat exceed the proboscis, black-scaled, with bluish 

 luster, the terminal segments clothed with numerous long hairs; head densely 

 yellowish scaled on the occiput, with a silvery luster; the yellowish thoracic stripes 

 are much more diffuse behind the middle than in the female; the stripes become 

 greatly expanded on the sides and they also coalesce more or less with the yellowish 

 scaling around the antescutellar bare space; the abdomen is black-scaled above, the 

 second segment with pale basal band, the succeeding segments with lateral basal 

 triangular segmental white patches; the under surface white-scaled, with narrow 

 apical black bands on the segments. Length, 5.5 mm. 



Thirty-five specimens from Cordoba, Mexico, bred from larvae in temporary 

 puddles. (F. Knab)

Original Description of Aedes akgentescens: 



Female. Proboscis long and slender, black-scaled; palpi black-scaled; head with 

 the occiput clothed with silvery scales, a large and dark spot on each side; meso- 

 notum clothed with deep brown scales and with two subdorsal lines of silvery scales; 

 these lines are much broadened along their middle third, becoming much attenuated 

 posteriorly, reaching the scutellum well to the sides of the antescutellar bare space; 

 bare space bordered with silvery scales; scutellum silver-scaled; abdomen deep 

 black, with coppery luster above, and with lateral basal segmental triangular silvery 

 white spots; beneath creamy white, with large triangular black apical segmental 

 lateral spots, which do not unite to form bands; wings with dark long and narrow 

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

 pale at base and beneath, tibiae narrowly pale-scaled on the under side; tarsi not 

 ringed; claws toothed on all the feet. Length, 2.5 mm. 



In the male the palpi exceed the proboscis, black-scaled, the terminal portion 

 densely clothed with long black hairs; head with the vertex clothed with dull silvery 

 scales; the markings of the mesonotum similar to those of the female, but the sub- 

 median stripes greatly expanded on the middle portion; abdomen black-scaled above, 

 with slight coppery luster, the basal segmental lateral spots becoming united into 

 bands on segments 3, 4, 6, and 7, eighth segment mostly whitish scaled. Length, 

 3.5 mm. 



Six specimens from Cordoba, Mexico, and Almoloya, State of Oaxaca, Mexico, bred 

 from larvie in temporary puddles. (F. Knab) 



T?/pe. Cat. No. 11965, U. S. N. M. 



The light markings show a silvery metallic luster, with a grayish cast, which 

 varies in intensity in different specimens. 



Description of Female, Male, and Larva of Aedes cuneatus : 



Female. Proboscis moderate, subcylindrieal ; labellae conically tapered; 

 vestiture brownish-black; setae minute, curved, black, those on the labellae more 

 prominently outstanding. Palpi short, about one-fifth as long as the proboscis ; 

 vestiture of blackish-brown scales and moderate black setae. Antennae filiform, 

 the joints subequal, rugose, pilose, black, second joint a little swollen towards 

 middle, its base pale; tori subspherical, with a cup-shaped apical excavation, 

 luteous, brown on inner side ; hairs of whorls moderate, sparse, black. Clypeus 

 rounded triangular, with a slight median groove, depressed, dark brown, nude. 

 Eyes black. Occiput dark brown, clothed with narrow, curved scales on vertex, 

 fiat appressed ones on the sides, silvery-white, an indistinct brown spot on sides, 

 a group of erect forked pale scales on nape ; bristles along margins of eyes black, 

 a tuft projecting forward between the eyes pale yellow. 



Prothoracic lobes elliptical, remote dorsally, dark brown, clothed with narrow 

 lanceolate pale scales and dark bristles. Mesonotum dark brown, clothed with 

 narrow curved scales, dark bronzy brown on lateral thirds, medianly a rather 

 broad, pale-brown longitudinal stripe, bordered on either side by a narrow dark-
