AEDES ATLANTICUS 799 



lateral hairs triple on first segment, double on the second, single on succeeding 

 ones; tracheal tubes broad, expanded into bladders in the metathorax and 

 slightly also in the seventh abdominal segment. Air-tube stout, about twice as 

 long as wide, gradually tapering outwardly; pecten of stout teeth, extending 

 over basal two-thirds of tube, evenly spaced; a small tuft a little beyond the 

 middle; single pecten-tooth a long spine with three basal branches. Lateral 

 comb of the eighth segment of eight or nine thorn-shaped scales in a line ; single 

 scale with elliptical base, slightly fringed with minute spinules and with a long 

 smooth rounded terminal spine. Anal segment longer than broad, ringed by the 

 plate ; dorsal tuft a long hair and brush on each side ; a single lateral hair ; ven- 

 tral brush well developed, rather short, confined to the barred area and poste- 

 riorly situated ; anal gills as long as the segment or longer, sharply tapered, the 

 lower pair a little shorter than the upper. 



Egg (plate 146, fig. 681). Sharply fusiform, black, reticulate, the reticula- 

 tions long and hexagonal along one-fourth at both ends, the intermediate por- 

 tion with rhomboidal reticulations. 



The eggs are laid singly. The larvae are undoubtedly inhabitants of tempo- 

 rary ground-pools, though we have no notes on the life history.

Baton Eouge, Louisiana (J. W. Dupree) ; Westpoint, Mississippi, August 11, 

 1904 (H. S. Barber) ; Corinth, ]\Iississippi, Augl^st 14, 1904 (H. S. Barber) ; 

 Jacksonville, Florida (H. Byrd) ; Scott, Arkansas, August 31, 1908 (J. K. 

 Thibault, Jr.). 



Aedes tormentor inhabits the Gulf coast region, the related Aedes atlanticus 

 the Atlantic coast region, but both species occur in Florida. Both have been 

 confused by Theobald and his followers with Aedes serratus, from which they 

 differ in the coloration of the legs. The median stripe of the mesonotum is 

 usually about one-fourth its width and is continued over the antescutellar 

 space to the posterior margin.

Original Description of Aedes atlanticus : 



Figured by Prof. J. B. Smith under the name " Culex serratus Theobald " as de- 

 termined for him by Mr. Coquillett (N. J. Agr. exp. Sta., Rept. Mosq., 280, fig. 

 86, 1905). While it is possible that this is the true serratus of Theobald, described 

 from Brazil and Guiana, we do not think it is probable, especially in view of what 

 we note under Aedes tormentor above. We therefore propose a new name for the 

 Atlantic coast form. Prof. Smith has taken it in New Jersey and the senior author 

 at Sanford, Florida.
