Allied to Tephritis but distinguished from it and from other

 limited to the apex, by the scutellam usually possessing only one 

 pair of b.sc. and the siender body. 



Head broader than high ; f rons broad ; eyes rounded ; epistoma 

 fairly prominent; cheeks rather narrow; proboscis short, geniculate 

 but the flaps not much prolonged; antennae placed at the middle 

 of the eyes, with the third joint broad, more than twice the length 

 of the second joint and pointed at the tip, above; arista bare; oc. 

 fairly strong; s. or. 2, the upper short and white, i.or. 3 or 2; ocj). 

 Avell developed, genal bristle fairly well developed to weak. 



Thorax v^'ith a complète chaetotaxy; 1 mpl.; scutellum usually

TYPE : Mn.^ra .■^tellata, Fuessly (1775). 



Only four species of this comparatively .small gonus are known 

 so far from Egypt, thrce of which. amoenn, stellatn and rhitd. bave 

 a wide gengraphical distribution. T. niiçjirr is .so far known onlv 

 from Persia, Algiers and Egypt. 



The members of this genus are ail flower-head feeders and they 

 seem to be entirely confined to the Natural Order Compositae.
