NEW SPECIES OF DIPTERA FROM NORTH CAROLINA 
AND FLORIDA 
By Charles W. Johnson. 
Boston Society of Natural History. 
The following descriptions of the species from Florida have 
been taken from the manuscript of a supplementary list of the 
Diptera of Florida, which it seems undesirable to publish at 
present when so much still remains to be done on the insect 
fauna of that state. 
Macrocera floridana sp. nov. 
cf. Head yellow, ocelli black, antennae brown, base yellow. 
Thorax yellow, with three broad shining brown stripes, the lateral 
ones shortened anteriorly. Abdomen yellow. Llalteres and legs 
yellow, tarsi brown. Wings hyaline, slightly tinged with yellow, 
veins brown, a single brown spot is present at the bases of the 
submarginal and first and second posterior cells; only a small 
portion of the spot is in the first posterior cell, the slight brownish 
tinge at the tip of the wing is entirely due to minute hairs. Length 
4 mm. 
Two specimens. St. Augustine, Fla., April 16 and 17, 1919. 
This species is related to M. clara Loew, but is separated by 
the absence of brown at the apex of the wing and at the stigma 
and the smaller clouding at the center of the wing. 
Psilocephala subnotata sp. nov. 
cf. Face and front black, entirely covered with a whitish 
pollen, in certain lights showing two dark spots above the base 
of the antennae, eyes narrowly separated, about one third as wide 
below the ocelli as at the vertex, antennae and proboscis black. 
Thorax blackish with light gray vittae bordering a dark central 
stripe, pleura and scutellum black grayish pollinose, the latter 
with four black marginal bristles. Abdomen black with dense 
silvery white pollen and white hairs, the third and fourth seg-
