Tabanidae. 131 



side. Wings hyaline witli brown veins. flalteres brown with the 

 apex of the knob pale. 



Feniale. I do not know the female of this species, but I quote 

 the following from Brauer. Eyes unicolorous. Frontal band high 

 and narrow, frontal callus somewhat narrower than the band. Upper 

 eye-margin with yellow and often at the sides some black hairs. 

 Second joint of palpi (Fig. 39) slightly thickened and distinctly curved, 

 sparingly whitish haired, with niany short black hairs on the outer 

 side. Venter reddish without middle line and with the apex grey. 



Length 15 ram. 



This species of which I only know the male, is in this sex 

 characterised by the rather short but overhanging hairs on the upper 

 eye-margin; the reddish venter without middle line seems to be a 

 good character in both sexes. Brauer says in his discription of the 

 male about the hairs at the upper eye-margin : „ . . . lange schwarze 

 naeh vorne gekriimmte Haare". But his figure shows rather short 

 hairs. 



T. Miki is very rare in Denmark, and only three specimens have 

 been caught in all, all males, one at Frederiksdal on ~'ls 1903 (Larsen), 

 one in Jutland at Horsens (H. I. Hansen) and one without locality 

 (R. Stamm). 



Geographical distribution: — The species has hitherto only been 

 known from middle Europe, and it seems rare. but I think it has 

 hitherto not always been recognised.
