shilling spots on the underside ; of thèse one is slightly deeper and 

 shorter, below the tip, and the other longer and ahiiost interrnpted 

 in the middle at the base. Pleurae wholly yellow and hearing some 

 pale yellow pubescence. 



Abdomen entirely yelh)w with cinereous cross-bands on tiie hind 

 niargine: of the second, third and fourth segments; the fifth segment 

 is somewhat shining; the pubescence is short and pale near the liase 

 but longei' and darker towards the tip; the apical half of the abdo- 

 men v>ears strong black bristles whicli are adpressed on the third 

 and fourth segments and erect on the fifth. Venter wholly yellow, 

 With a few black bristles on the fifth segment Maie hypopygium 

 reddish-yellow and shining; female ovipositor short, yellow on its

Wings with ail the veins yellow (except the short stump on R2 + 3 

 wliich is dark brown), and with three yellow cross-bands disposed 

 •is foUows : the one near the base, which is the smallest, extends 

 from below the humerai cross-vein over the M. and Cu. cells and 

 f^nds in the top of Cu.l cell; the second which is the widest, extends 

 along the middle of the wing from the costa, over the stigma to 

 about the centre of Cu.l cell, its outer edge runs along the radio- 

 median cross-vein, this band being widest at its centre and gradually 

 narrowing towards both ends; the third band is situated a little after 

 the middle of the wing and extends just below the costa, over the 

 stump outwardly on R4 + 5 and bends down, following the upper 

 margin to the tip of the v/ing, thus forming an angle with the end 

 turned towards the stump on 112 + 3; ail thèse bands are edged with 

 brown, especially at the tips of the lines forming the third angular 

 band.

Up to the présent this species is not indigenous to Egypt. Only 

 5 spécimens are known (2 maies and 3 females) in the Ministry of 

 Agriculture's collection labelled "Tul Keram 9.8.1919, bred on 

 Faqus." It is recorded from India, where the larva is known to 

 breed in melons and other cucurbitaceous fruits, to which it is said 

 to be very injurions, more than ninety per cent of the crop appa- 

 rently being destroyed by it. In that country it is known as the Ba- 

 luchistan Melon- fly.
