1927 ] Bees of the Genus Halictus from Miami, Florida 205 
high, much narrowed above. Third submarginal over one and 
one-half times as long as the second on the marginal vein. Legs 
dark, clothed like the rest of the body with pale pubescence.: 
Male. Differs from the female as follows: Mesothorax of a 
lighter green and more shining. Abdomen black, long, very 
slender, smooth and shining above along its entire length. Facial 
quadrangle much narrower below. Face below antennae with a 
dense covering of short white pubescence. Antennae below tes- 
taceous from third joint on. Third antennal joint a little longer 
than second. Tegulae more closely punctured. Ridges on disk 
of propodeum shorter and less distinct. Wings clearer, stigma 
and veins darker, the latter more sharply defined. Second sub- 
marginal cell shorter. 
Described from twelve males and fourteen females captured 
at South Miami, Miami, Cape Florida (across the bay southeast 
of Miami), Golden Beach and Hollywood (both north of Miami). 
They were visitors to the flowers of Lepidium virginicum, Warea 
Carteri, Galactia pinetorum, Sida carpinifolia, Chrysopsis Tracyi 
and Alternanthera floridana. Type and allotype in the author’s 
collection. 
In the Sandhouse Key to females this species runs next to 
ellisice Sandhouse from Massachusetts (3,11), but differs mainly 
in the following characters: antennae testaceous at the tips, 
scutellum closely punctured all over (no smooth spots on the 
disk), tegulae slightly testaceous above, disk of propodeum with 
ridges on basal half. 
H. (Chloralictus) nymphalis F. Smith 
Described from St. John’s Bluff, East Florida (4,68.) There 
are in my collection specimens from Miami, South Miami and 
Hollywood (north of Miami) and also one from Jacksonville 
(near the type locality) captured September 25, 1925. At South 
Miami it flies with slight interruption throughout most of the 
year, but seems to be present in greater numbers during the fall 
months. It has been taken at the flowers of Opuntia austrina, 
Croton linearis, Galactia pinetorum, Lepidium virginicum, Warea 
Carteri, Chrysopsis Tracyi and Portulaca oleracea. It prefers
