Linne, Syst. Nat., ed. X, T. i, 601, 1758. 



Moderately pubescent flies of usually brownish black or grey 

 colour or orange yellow, but sometimes with brownish ferruginous or 

 conspicuous reddish orange markings and usually with longitudinal 

 rows of grey spots or flecks on the abdomen, in size varying in a 

 great extent from more than 20 mm. to 8 mm. 



Head as broad as or broader than the broadest part of the 

 thorax, in the male much more convex than in the female. Frons in 

 the female rather narrow, extend from the vertex to the antennae, 

 being known as the frontal stripe which is from two to eleven times 

 longer than broad, but in the male very short, limited to a triangle 

 above the antennae which extends up to a point between eyes as the 

 frontal triangle ; frontal stripe parallel-sided or divergent, very often 

 bearing some spaces denuded of dust or pubescence, which are known 

 as the frontal calli, and of these the lower one occupying a position 

 above (not just above) the antennae, and the other one placed at about 

 the middle of the frontal stripe and varying specifically in shape (some- 

 times wanted) from quadrate to linear, and very frequently " connected 

 with the lower callus by a narrow line ; there is very seldom two 

 other distinct calli of which a large one appears at immediately above 

 the antennae and a small one on the vertex ; the former is usually
