804 MOSQUITOES OF NORTH AMEEICA 



Life history and habits Tinknown. Dr. Pazos has obtained eggs and accord- 

 ing to a drawing he sent ns they are rhomboidal in outline. They were de- 

 posited singly. The larvae undoubtedly occur in temporary ground-pools, as 

 do those of the related species. 



Cuba. 



Havana, November 1, 1903 (J. E. Taylor) ; Cayamas, May 8, 10, 31 (E. A. 

 Schwarz) ; San Antonio de los Banos (J. H. Pazos). Eeported also from Isle 

 of Pines (Pazos). 



Aedes iracteatus is one of a group inhabiting the Antilles, which differ on 

 each island. The differences are but slight, yet we consider them, tentatively 

 at least, as specific. In the Bahamas this species is represented by Aedes plu- 

 tocrwticus, in Santo Domingo by A. balteatus and in Jamaica by A. tortilis, 

 while we have from St. Thomas a single specimen differing slightly from all, 

 but which we do not venture to describe on so slender a material. We think 

 these are all species, not races of one species, since the only two larvae knovm to 

 us, namely those of bracteatus and tortilis, differ. 



The disc of the mesonotum varies considerably in intensity of coloration and 

 in the definition of the color-pattern. In some specimens this area is dark 

 coppery brown and blends with the darker lateral areas, while in others it is 

 of a creamy color and in strong contrast with the lateral zones.

 thorax coppery bronze, a distinct dark brown spot occupying the anterior halt 

 laterally joined behind to the lateral brown area; medianly there are two rather 

 ill-defined brownish stripes; abdomen black above, with narrow basal white 

 bands, beneath white, the hind angles with black triangular spots. Wings dark 

 brown, scaled. Legs black, the tibia and tarsi bronzy beneath; femora white on the

DESCKtenoN of Female and Male or Aedes plutocraticus (Larva Unknown) : 



Female. — Proboscis moderate, subcylindrical ; labellae conically tapered; 

 vestiture black; setae minute, curved, black, those on labellae more prominently 

 outstanding. Palpi short, less than one-fifth as long as the proboscis, clothed 

 with black scales and moderate, stiff bristles. Antennae filiform, the joints sub- 

 equal, rugose, pilose, black; second joint slightly thickened, fusiform, yellow 

 at base ; tori subspherical, with a cup-shaped apical excavation, luteous, black- 

 ish and with a patch of fine black hairs on inner side ; hairs of whorls moderate, 

 sparse, black. Clypeus rounded triangular, depressed in the middle, nude, 

 black. Byes black. Occiput black, clothed with broad, flat, dull white scales, 

 a median line of narrow, curved, yellowish silvery scales on the vertex and 

 similar ones along eye-margins, a large, diffused black patch on the sides close 

 to eye-margin, many erect forked scales on nape, some black, most pale yellow; 

 setae along margins of eyes black, those projecting between eyes pale yellow. 



Prothoracic lobes elliptical, remote dorsally, dark brown, eoncolorous with 

 sides of mesonotum, with some whitish scales and numerous black bristles. 

 Mesonotum dark brown, clothed with narrow curved scales, a broad golden
