filament and row of serrate hairs within ; process below furcate, with a row of 

 hairs and a tuft at tip of each limb; basal angle moderate, with four stout 

 feathered hairs within ; a row of long hairs at base. Maxilla elongate hemi- 

 spherical, divided by a suture ; inner half indented at outer third, with a row 

 of long processes with plumose divided tips on the margin, two rows of cilia 

 within, the first one running the whole length, a tuft of hairs at tip ; outer half 

 with two filaments articulated on a widely furcate base at outer third, outer part 

 hairy, a spine on other side; palpus stout, over half as long as maxilla, with 

 four minute apical digits. Thorax rounded, wider than long. Abdomen moder- 

 ate, anterior segments shorter; lateral hairs in threes on first segment, in twos on 

 second, single on third to sixth. Air-tube stout, tapered outwardly, over twice 

 as long as wide ; pecten of coarse, evenly spaced teeth, occupying basal half ; a 

 tuft of six or eight hairs just beyond pecten ; single pecten-tooth a long spine 

 with five short basal branches. Lateral comb of eighth segment of ten or eleven 

 scales in a straight row; single scale ending in a long spine, some fine spinules at 

 its base. Anal segment longer than wide, ringed by the plate ; dorsal tuft a long 

 hair and brush on each side ; a small lateral hair ; ventral brush well developed, 

 confined to the barred area; anal gills as long or longer than the segment, 

 tapered to a sharp point. 



The larvae live in temporary ground-pools. Mr. Knab found them in the 

 rainy season in a pond choked by vegetation, which is dry in the dry season.

The records for the United States are based upon misidentifications, the speci- 

 mens belonging to either Aedes tormentor or Aedes atlanticus. A'edes serratus 

 varies in coloration and specimens occur with a very narrow thoracic median 

 stripe.

Obioinal Descedption or Aedes toementoe: 



This species was collected by Dr. Dupree in Baton Rouge, La., and named " Culex 

 serratus Theob." as was also the species we describe as atlanticus. We do not believe 

 that either of these forms are identical with the South American species, certainly 

 they both cannot be. It is characterized in the table above.
