Aedes tormentor, new species. Fig. 4. 



This species was collected by Dr. Dupree in Baton Rouge, La., 

 and named " Culex senatus Theob." as was also the species we des- 

 cribe as atlanticus. We do not believe that either of these forms are 

 identical with the South American species, certainly they both can- 

 not be. It is characterized in the table above.
