. Bulletin. Natural history; Natural history. Fig. 224,—Distribution of Tabanus equalis in Illinois and North America. Tabanus exilipalpis Stone Tabanus exilipalpis Stone (1938:54). Type- locality: South Carolina, Beaufort. Rather small ( mm); eye with very short, sparse pile; palpi very slender, slightly thickened at base; bas- al plate of antenna rather broad with distinct angle; frons narrow, 4 times as high as width at base; beard white; wings hyaline, including costal cell; legs yellowish brown; abdomen dark brown with pale median stripe, which widens at apex of each segment, segments 2—5 with round pale sublateral spots. Male with densely pilose eyes; occipital bor- der with long black hairs recurved anteriorly; eye facets essentially one size. The hair on the eyes of females mav easily be overlooked, but the combina- tion of slender palpi, the median stripe on the abdomen, and roimded sublat- eral spots will separate this species from most other species likely to be found in Illinois. The larva and biology of this spe- cies are unknown. T. exilipalpis is a central and south- ern species, extending from Alabama north to western Kentucky, apparently with a disjunct population along the coast of South Carolina (Fig. 225). As yet this species has not been collected in Illinois although specimens have been examined from western Kentuck\'.. Fig. 225.—Distribution of Tabanus exilipalpis in North America. Tabanus fairchildi Stone Tabanus fairchihli Stone (1938:63). Tvpe- locality: New York, Taghkanic, near Ithaca. Moderate size (14 mm); blackish brown; antennae black, with first seg- ment swollen above; sides of subcallus with few hairs laterally; eyes bare or with short, scattered hairs; thorax does not strongly contrast with abdomen; wing hyaline; bifincation of third lon- gitudinal vein without a dark spot; abdomen with 3 rows of pale spots (Fig. 176). Male eye facets somewhat differentiated, but line of demarcation not distinct; eves often with short, s
