THE GENUS MEGARHINUS. 
This is the other genus (fig. 21), the species of which are more or 
less abundant in the South, which should be investigated by Southern 
observers in regard to its possible connection with malaria. As indi- 
cated in the synoptic table, the mosquitoes of this genus are readily 
distinguished by the curved beak, which is also well shown in the draw- 
ing. They are especially distinguished also by their metallic greenish 
or bluish coloration. Nothing is known of the life history of the mos- 
quitoes of this genus, and the species known to occur in this country 
are distributed as follows, so far as our records go: 
MEGARHINUS FEROX Wied. 
Habitat: District of Colombia, August 22 (Pergande); (Georgia according to 
Walker’s list). 
MEGARHINUS HMORRHOIDALIS Fabr. 
Habitat: (Cayenne and Cuba according to Osten Sacken’s catalogue). 
MEGARHINUS PORTORICENSIS Roeder. 
Habitat: Benoit, Miss., July 18 (Hine). 
MEGARHINUS RUTILUS Coq. 
Habitat: North Carolina; Georgiana, Fla. (Nat. Mus.).

THE GENUS AEDES. 
The mosquitoes of this genus (fig. 22) are minute forms, insignificant 
in color, and the only one of which we possess specimens, viz., A. sap- 
phirimus, is shown in the accompanying figure. We have received it
