A Mùiiugmph of Egyptian Diptcta. ï9. 



tlie baek with blaek pubeseence. Wings with the Lhird longitudinal 

 veiu usually bristly over its wliole lengtli, or at least towards the 

 base; anal eell usually with its lower angle drawn out into a point, 

 and therefore as long as, or longer than, the second basai cell 

 (obtuse in Goiiycjlossum). Wing-pattern of the banded type. The 

 species of this tribe are most abundant in tropical or subtropical 

 eountries, but are not rare in temperate régions. The larvae often 

 live in fruits, like those of the Dacinae; but some species mine into 

 the leaves of umbelliferous plants or of Compositae; a few species 

 are gall-makers, but none live in the flower heads of the Compositae. 



2nd Tribe : Myiopiliiiintu'. This tribe has the same characters 

 as the preceding, but the anal cell is always obtuse, its lower angle is 

 never drawn out in a point; the ovipositor is long and cylindrical; 

 the wings are banded. The species are found exclusively in temperate 

 eountries, being wanting in the tropics ; the larvae live only on plants 

 of the family Compositae, and often make galls. 



ord Tribe : Tri/ptuiriii i/iitc. Occipital row usually formed of 

 .strong yellow bristles, which are usually obtuse at the end. Thoracic 

 pubescence yellowish. Wings with the third longitudinal veins 

 usually bare; anal cell never longer than the second basai cell (obtuse 

 in some forms). Wing-pattern usually of the reticulate type, rarely 

 banded and sometimes hyaline. Ovipositor flattened. Arista usually 

 bare. The species occur in temperate eountries and also in cold 

 régions; the larvae live usually in the flower-heads of the Composi- 

 tae, and sometimes make galls, even on the roots of plants of this 

 family." 



The family Trypaneidae is a very large one, over 1000 species 

 being known from ail over the world, and this number goes on in- 

 creasing every year. The family has a wide distribution over ail 

 the globe, from the Arctic to the Tropical régions Over 300 species 

 are known from the Palearctic région. 



The known gênera of Egyptian Trypaneids are arranged as fol 

 lows according to Bezzi's classification.
