BEES OF THE GENUS HALICTUS FROM MIAMI, 
FLORIDA 
By S. Graenicher, 
South Miami, Fla. 
The following two species belong to the group of Chloralictus 
with punctured tegulse. 
IL (Chloralictus) marinus Crawford. 
Described from the female (1,99), The punctured tegulse, 
which are pointed posteriorly, place it next to tegularif ormis 
Crawford (New Mexico) in the Sandhouse key to females (3,1), 
but in the latter species the disk of the propodeum is granular 
while in marinus it has longitudinal rugse running the length of 
the disk. 
Male. Entire face up to the median ocellus covered with a 
dense short white pubescence. Head behind the eyes, sides of 
meso — and metathorax, scutellum, femora and sides of ab- 
domen with long white hairs. Mesonotum and abdominal seg- 
ments one to four above, shining and nearly bare. Facial qua- 
drangle much narrower and longer than in the female. Clypeus 
produced half its length beyond the eyes. Antennae dark above, 
light ferruginous underneath from second joint on. Tegulse bare, 
shining, the punctures more plainly visible than in the female, 
Abdomen slender, with hardly a trace of testaceous coloration 
along the apical margins of the segments. Knees and tips of 
tibiae narrowly testaceous, tarsi nearly white. 
This species occurs at Miami Beach (across Biscayne Bay 
from Miami), where I have collected both males and females in 
January, July, August and December, at the flowers of the sun- 
flower Helianthus debilis. 1 Quite recently (April 23, 1927) five 
males were found at Golden Beach (on the Atlantic Ocean north 
of Miami), visiting the flowers of Alternanthera floridana; also, 
one male and two females (April 29) on the sand dunes along the 
Nomenclature according to Smalts “Flora of Miami” and the same 
author’s “Flora of the Southeastern United States.”
