on the apex of the tstigma and extendint,' down as far as R4 + 5, 

 tonching this vein ; sometimes this indentation is interrupted by a 

 thin dark line along R2 + 3 and in tliis case the lower margin of this 

 thorefore isolated spot does not toiich R4 + 5; the hyaline inden- 

 tations at the lower margin are : one in the apical half of Cnl cell 

 exactly lielow the radio-median cross-vein, with its upper margin 

 almost reaching M3 + Cul; the second and third indentations are 

 in 2nd M2 cell, the former which is by far the largest of the three 

 lower indentations is at the base and its upper margin touches 

 Ml close to the médian cross-vein; the third lower indentation 

 is the smallest and situated towards the middle of 2nd M2 cell 

 and may be rounded or oblong. The isolated hyaline spots 

 are variable in number, shape and position and are as fol- 

 lows : one oval spot at the base of R5 cell with its lower 

 margin touching Ml and its upper margin not quite reach- 

 ing R4 + 5; sometimes one smaller rounded spot in R5 cell, above the 

 médian cross-vein ; but this spot is usually absent ; one rounded spot 

 at the apex of R cell with its upper margin touching R4 + 5, this 

 spot is also frequently absent; one faii'ly large rounded spot in Ist 

 M2 cell below the radio-median cross-vein with its lower margin 

 touching M3 + Cul ; sometimes this spot runs into the spot above it 

 (the one at the apex of R cell) ; in addition there are two very small 

 and rounded spots at the apex of Ist M2 cell and one at the hind 

 border below the médian cross-vein, but thèse are also usually absent ; 

 inferior angle of Cu cell drawn out into a very short but pointed 

 angle, shorter than the M. cell ; costal bristle not strong. 

 Squamulae pale yellow; haltères yellow. 



Ail the known spécimens of this interesting species are from 

 Egypt. Seven of them (5 maies and 2 females) are in my collection 

 captured as follows : Wadi Hoff, 22. III. and 9. VI. 1922'; 7th Tour, 

 Suez Road 23. VII. 1922 and 3. VI. 1924 ; Ezhet-el-Naghl 19. VII. 

 1922 and two spécimens, both maies, in the collection of the Ministry 

 of Agriculture, captured by Mr. E. W. Adair in Wadi Hussein 

 (1. VI. 1919).

DIAGNOSIS: — A rather thick-set, brownish-yellow species, 

 easily distinguished by the very faint reticulation of the wings.
