each branch of the fork; fifth with black-scaled stem and pale 
fork; sixth pale; first sub-marginal cell much longer but about 
the same width as the second posterior cell, the stem about

ceJl equal to about the length of the cell; posterior cross-vein 
situated about half its own length distant from the mid cross¬ 
veins, all three pale. Fringe alternately black and white. 
Halteres pale ochraceous. 
Length of body 9 mm., of proboscis 4 mm., of wings 17 mm. 
Habitat .—Rio de Janeiro (Dr. Lutz) (4. 7. 1899); Mexico 
(Bellardi). 
Observations .—Described from two 9’ s received from Dr. 
Lutz in fair condition. These he calls the Great Spotted 
Mosquito. A very clear and beautiful species of the spotted¬ 
winged group. 
Dr. Lutz writes me that the larvae of this mosquito resemble 
greatly those of Psorophora ciliata; he has raised them on 
different occasions. Once he found them in a hollow tree in 
some water in which were larvae of Heteronycha, upon which 
they seemed to be living. 
Although he has never taken the insect on the wing he has 
observed it sucking the blood of a stork during the night. 
He adds in his letter that “ I think C. fulvus, Wied., and 
C. costalis (?), given as found in Brazil, might be badly-preserved 
specimens of C. Bigotii.” 
I do not know C. costalis, but I find a specimen in Bigot’s 
collection that is evidently C. fulvus, Wiedemann, and quite 
distinct. The apex of the wings is brownish—not spotted in 
C. fulvus.
