black patch on the lower part of the side; mesonotum with the 
anterior two-thirds clothed with shining light-yellow scales, a dark

pale yellow scales, a patch at the side separated by a yellow stripe 
running from the middle to the base of the wing ; scutellum yellow 
scaled; pleura dark, with patches of white scales; mesonotum deep 
brown, nude; abdomen black scaled above, with median basal 
elongate creamy spots on all the segments, which, however, do not 
unite to form a stripe, segments with lateral triangular basal white 
patches, beneath the abdomen is mostly creamy-white with black 
apical lateral triangular marks ; legs black, knees yellow scaled, tarsi 
with narrow yellowish-white basal rings, the ring at the base of the 
second tarsal of the hind legs slightly involves the apex of the first

cf. Palpi slightly shorter than proboscis, hairy on the apical 
portion, the two apical segments light ringed at their bases; abdomen 
with distinct basal white bands on the second to the fourth segments, 
on the succeeding segments broken into three spots, the median spot 
becoming elongate on the sixth and seventh segments, lateral cilia 
abundant, pale. 
Length .-—4 mm. 
Five specimens, Chagres Eiver, Panama (A. Busck), bred from 
larvae in pot holes along the river. 
Apparently nearly allied to Danielsia tripunctata, Theobald, and 
to Danielsia mediomaculata, Theobald, abdominal marking differing 
from the former and the thoracic marking from the latter. We 
would place Danielsia , Theobald, as a synonym of Aedes in our 
classification.”
