TABANUS PAGURAS. Fair. 



Thorax ash colour, scutellum large, hody brown, 

 legs light brown, the femora and tarsi black : wings 

 slightly coloured with a blackish tint. 



Expansion of the wings 1 inch 7 lines, length of 

 the body 10 lines. 



Inhabits the Xew Forest in Hampshire, in the 

 months of June and July. 



The Tabani are remarkable for their large eyes, 

 and when living are in general very beautifully co- 

 loured, which fade in the dead insect. In the males 

 of this genus of insects the eyes meet or are divided 

 by a very narrow line down the front ; but in the 

 female the line is considerably wider, and by this the 

 sexes are readily distinguished : the antennas are 

 placed low in the front of the head, the basal joints 

 are short and cup-shaped; the second portion is large 

 and in the form of a sickle : the mouth has a prom- 

 inent proboscis or moveable trunk, which protects 

 the haustellum or suckers, admirably adapted to re- 

 ceive the blood liberated by the lancets, with which 

 the mouth is furnished : thorax dark grey and covered 

 with hair of the same colour : scutellum large : body 

 biown, with a row of triangular whitish spots down 

 the back and sides ; the margin of each segment with 

 a pale brown undulating band reaching from side to 

 side : wings transparent, the nervures light brown.
