FIVE NEW SPECIES OF NORTH AMERICAN TABANID^. 



JAS. S. HlXE. 



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 antennas 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.
