42 H. C. EFFLATOUN. 



Abdomen brownish-yellow and covered with a very délicate 

 yellowish-grey pulverulence, except on the upper margins of the 

 second and third segments; maie hypopygium small and rounded, 

 yellow, but shining black at the tip and with a yellow, perpendicular 

 middle organ below; it bears sonie pale yellow erect hairs; female 

 ovipositor shorter than the two apical segments together, brownish- 

 yellow and almost twice as broad on its basai half than on its apical 

 half. The pubescence on the abdomen is nniformly pale yellow and 

 somewhat erect; the strong apical bristles are brownish-yellow. 



Legs entirely pale yellow, fairly strong, with the hind tibiae a 

 little bent. 



Wings hyaline with three incomplète, pale brownish-yellow 

 bands; the first of thèse, near the base, extends from the costa to the 

 lower angle of Cu cell; the second band covers the stigma and ends 

 towards the middle of Cu 1 cell, Avith its outer margin running on 

 the radio-median cross-vein; the third extends from the costa, runs 

 over the médian cross-vein to M3 + Cul ; the second and third bands 

 are sometimes interrupted ; ail the veins are yellow, except RI for a 

 very short distance near its base, and the radio-median and médian 

 cross-veins blackisl] ; costal bristle double. Squamulae whitish; hal- 

 tères yellow. 



This species is common throughout Egypt and its larva breeds 

 in the fruit of Zizyplnis spina-christi and Z. jujuha ; the adults may 

 be reared from the fruits from almost every locality during the 

 months of October to May. As far as I am aware there is no record 

 of the capture of the adult out in the fields. C. incom'pleta has a 

 wide geographical distribution, being known from the Sudan (as the 

 "Naleback fruit-fly"), from Erythrea and Italy.
