Type.—Female, collection unknown, originally in the collection of 
M. Percheron. 
Type locality.—United States. 
Distribution.—Atlantic Coast States from New Jersey to Florida; 
Louisiana, Arkansas, and Arizona. March 12 (Paradise Key, Fla.) 
to August 31 (Mimsville, Ga.). In the United States National 
Museum, 120 females, 23 males. 
Knab (6) pointed out that the Nearctic form, commonly deter- 
mined as Zabanus mexicanus Linnaeus, differs from the true meai- 
canus and other Neotropical species, and to it he applied the name 
T. flavus Macquart. Since this name is preoccupied, Bequaert re- 
named the species crepuscularis. 
The Genus ANACIMAS Enderlein 
Anacimas Enderlein, Deut. Ent. Ztschr. 1923: 545; Mitt. Zool. Mus. Berlin 11: 
376, 1925. (Genotype, Anacimas limbellatus Enderlein.) 
Generic characters——Small to medium sized, rather stout species; eye pilose 
to nearly bare; in male the large and small facets probably sharply dif- 
ferentiated (male of genotype unknown); frons of femaie rather broad; no 
ocellar tubercle; third antennal segment with five divisions, the first with a 
distinct but obtuse GCorsal angle; rather long, Scattered hair on both basal and 
annulate portions of third segment; palpus short and stout, with erect hair; 
in female the proboscis no longer than palpus; wing venation normal. 
Key to the Nearctic Species of Anacimas 
1. Wing veins not margined with brown; median callus of female narrow 
and not strongly convex; a pair of narrow, sublateral, gray stripes 
on mesoscutum and a broader pair on abdomen above; (central 
part of the United States)=2 =. 22-252. dodgei (Whitney), p. 28. 
Wing veins margined with brown; median callus of female rather 
broad and decidedly convex; mesoscutum without gray stripes 
and those on abdomen more yellowish brown; (southeastern part

Tabanus dodgei Whitney, Canad. Ent. 11: 37-88, 1879; Hine, Ohio. Nat. 5: 236, 
1904; Bequaert, Boston Soc. Nat. Hist. Occas. Papers 8: 86, 1938. 
Stout, medium sized; brown and gray, the gray forming conspicuous but 
narrow stripes on thorax and two broader stripes on abdomen. 
Female. Length 18-15 mm. Eye pilose, purple, with two green stripes, the 
upper stripe wider than the lower and wider than the space between. Frons 
about two and one-half times as high as width at base, with sides parallel or 
slightly divergent above, yellowish gray, with black hair; basal callus trans- 
verse, dark brown, often rather irregular; a narrow median callus above, usually 
narrowly joined to basal callus; vertex somewhat swollen, sometimes partially 
denuded, shiny dark brown, but with a median depressed line and no ocellar 
tubercle; subcallus yellowish gray. Clypeus and genae nearly white, with 
long white hair. First two antennal segments yellow, with black hair above; 
third dark brown to black, except for extreme base, which is yellow; basal 
portion slender, rounded above; annulate portion about equal in length to basal 
portion. Second palpal segment short, stout, pale cream colored, with a mixture
