of the Family 'Tabanide. 291 
In the following tables I have assumed the antenne are 
simple, with no tooth or angle, when there is no express 
mention of such a tooth or angle in the description ; the 
eyes in all the species not expressly mentioned as hairy are 
assumed to be bare. 
Palearctic Region. 
The description of S. dorsalis, by Coquillet, seems to 
point to its being very nearly related to S. vituli, Fabr. 
For the species from this region Loew’s paper in the Wien. 
ent. Monat. i. p. 850 (1858) should be consulted.
