genus Tabanus 4 . 
T. nivosus Osten-Sacken. A female from Solon Springs in Douglas 
Co. (length 15 mm), and one from the Yellow river in Burnett Co. 
(length 12 mm) agree with 2 specimens from Sandusky, Ohio, and 2 
from Orono, Maine, in our collection. In each of the Wisconsin speci¬ 
mens the gray thoracic stripes are obsolete posteriorly, and the front 
is of equal width throughout. 
T. reinwardtii Wiedemann. 1 female from Milwaukee. Length 
about 13 mm. 
T. stygius Say. 1 specimen from Sunny Slope, Waukesha Co., 
(Dr. Geo. P. Barth), and 1 from Milwaukee Co. 
T. irimaculatus Palisot de Beauvois. 2 females taken at Sunny 
Slope, Waukesha Co., by Dr. Geo. P. Barth. One of these has in addi¬ 
tion to the median triangular white markings on abdominal segments 
3, 4 and 5, a roundish white spot on each side of segment 2, situated 
midway between the anterior and posterior margins. 
T. vivax Osten-Sacken. 2 specimens from the St. Croix dam in 
Douglas Co.; 1 from Pansy, and 2 from the Yellow river in Burnett 
Co., and 4 from Tenderfoot Lake in Vilas Co. All of these are females

largest one (from the St. Croix dam) reaches 17 mm. in length. 
T. zonalis Kirby. A female taken by Dr. Geo. P. Barth at Spider 
Lake, Vilas Co., in July 1912. This species is unique among the species 
of Tabarius on account of its black and yellow, wasp-like markings, 
it reminds one of such species as Temnostoma aequalis among the 
Syrphids. 
STBATIOMYIDAE. 
Most of the species of Stratiomijia and Odontomyia are conspicu¬ 
ous on account of their yellow or green stripes and bands on a dark 
ground color, and in connection therewith all the members of the 
family are called “soldier-flies”. Unbelliferous flowers and flowers 
arranged in flat-topped inflorescences, as in many species of Cornus, 
Viburnum, , etc., are especially attractive to flies of this family.
