TABANUS SPARUS subspecies MILLERI Whitney 
Tabanus milleri Whitney, Canad. Ent. 46: 344, 1914; Bequaert, Boston Soc. 
Nat. Hist. Occas. Papers 8: 86, 1933. 
The description of mzlleri was based upon specimens collected in 
Florida and differing from the typical sparus only in the presence, 
in fresh or relaxed specimens, of a rather broad, diagonal, purple 
band on the dark-greenish eye. Although originally described as a 
species, the writer does not believe it to be more than a subspecies 
occupying the southern portion of the species’ range and mingling 
with the typical sparus in New Jersey. It cannot be recognized in 
dry specimens. 
Cotype.—Female, probably no longer in existence. 
Type locality —# lorida.

FIGURE 28.—Antenna, front view of head, and palpus of (4A) Tabanus venustus and (B) 
T. johnsoni. 
Medium sized; wing variegated; abdomen with a median row of white 
triangles. 
Female.—Length 16-18 mm. Eye bare, purple, with two narrow green bands; 
in dried specimens the dark band between the two green bands usually visible. 
Frons brownish gray, about three times as high as width at base, slightly 
widened to median callus; basal callus brown to nearly black, rounded, slightly 
higher than wide, not touching eyes; median callus spindle shaped, small, orange 
brown, usually separated from basal callus and set in a dark-brown or black 
pollinose area nearly as wide as frons; subcallus yellowish brown, the clypeus 
and genae grayer; hair of clypeus and genae sparse, brownish. Antenna brown, 
the extreme base of third segment somewhat paler; first and second with short 
black hair; third rather short and broad, with only a very slight excision be- 
yond the moderate dorsal angle; annulate portion but slightly shorter than basal 
portion, the annuli distinct. Second palpal segment brown, with short black 
and yellowish hair, rather slender and elongate. 
Mesoscutum with gray pollen and pile and longitudinal stripes of brown 
pollen; scutellum grayish; prescutal lobe with coarse black hair on lower 
margin. Pleura and sternum generally brown. Wing nearly hyaline, with 
dark-brownish infuscation as follows: Costal cell beyond humeral cross vein, 
band across cells R and M nearly to hind margin of wing, conspicuous spots on 
all cross veins and on fureation, a broad spot bordering middie of vein R., and 
entire margin cf wing, with a concentration and widening at each vein ending;
