FIVE NEW SPECIES OF NORTH AMERICAN TABANIDiE. 
Jas. S. Hine. 
Tabanus floridensis n. sp. 
Female, length 10 millimeters. Size and general appearance 
similar to T. pumilus from which it differs by the distinctly wider 
front. Frontal collosity transverse, as wide as the front, shining 
black and with a small denuded marking above it. Antenna 
narrow, distinctly narrower than in pumilus, first and second 
segments pale with black hairs above, third segment nearly black; 
face clothed with long white hair, palpi narrow, pointed, and 
•clothed with short white hair, proboscis dark, eyes naked. 
Thorax dark gray above with lighter stripes, wings hyaline, 
furcation of the third vein without a fork, legs dark reddish. 
Abdomen dark colored, hind margins of the segments, a series of 
more or less plainly marked middorsal triangles and a row of rather 
large spots on either side gray. 
Type female from Fort Meade, Florida, April 4, 1909. Twelve 
other females taken at different places in southern Florida in 
April. 
Although the species suggests pumilus it is entirely distinct. 
The front is much wider, the antenna are narrower, the legs are 
colored differently and the gray spots on either side of the abdo- 
men are larger. It is distinct from sparus and fratellus also, as 
will be found by comparing these same characters.
