DIAGNOSIS: — A .small black species, somewhat smaller than 

 U. mac ru /a, but distinguished from it by its femora which are black 

 except for the tip yellow and l)y the wings which possess the two first 

 bands united above. 



Maie and Female: — Length of body : 3—3.5 mm. ; ovipo.sitor : 

 1.9 mm.; wing : 2.8—3 mm. 



DESCRIPTION:^ Head very similar to that of U. 7na- 

 criira but the thorax is shining black owing to the much finer and 

 scarcer browni.sh-yellow pulverulence on the dise, leaving the three 

 usual kingitudinal lines more pronounced although inconspicuous ; 

 the humérus is tibick and u.suallv onlv with a small yellow s])ot lie- 

 low. 



Abdomen very similar to the preceding species but the pubes- 

 cence is not as dense and somewhat less bristly; the ovipositor, which 

 is distinctly shorter, is much more swollen in its basai half. 



Legs with ail the femora black except for the apices which are 

 vellow; tibiae and tarsi wholly yellow. 



Wings characterised by the pattern, which differs from that 

 of [■. marnrra as follows; the two first black bands are united above 

 near the base of R4 + 5. thus leaving the basai third of R3 and RI 

 cells, the subcostal cell, the stigma and the whole of the 2nd costal 

 cell black; the union of the third and fourth black bands is thicker 

 and the vertex of the deep hvaline indentatiou (limited l)y thèse 

 bands) never passes R4 + 5. 



Scjuamulae and haltères yellowish. 



I hâve often captured this species in the neighbourhoods of 

 Cairo on Centaurea paUescens, Linn. in the flower-heads of which 

 plant the larva lives, together with the larva of Terellia jaceae
