n. C. EFFLATOUN. 



latter; in RI cell there is a characteristic elongated hyaline spot on 

 the Costa resembling a drop, with its inflated end towards the 

 middle of Ri cell and its narrow end in the middle of the stigma; 

 in R3 cell there are two hyaline spots, the first of which is small 

 nnd rounded. at the tip of R2 + 3 on the costa, and the second, at 

 the tip of the cell is mnch larger, triangnlar and ending in R5 cell; 

 hère the dark patch radiâtes; the upper or first ray covers the tip 

 of R4 + 5(forming the outer margin of the last mentioned triangnlar 

 spot), the second ray rnns ol)liquely downwards and covers the tip 

 of Ml ; the third, fonrth and fifth rays run almost vertically down- 

 wards in 2nd M2cell, exceptthe fifth ray which covers the undulated 

 médian cross-vein; thèse five rays or dark narrow bands are almost 

 eqnidistant from each other and they ail end at the wing margin; 

 in addition there is one or two short, dark narrow bands in Ist M2 

 cell, which sometimes only reach M3 + Cnl; there is also a ronnded 

 hyaline spot in R5 cell near the base, touching Ml ; costal bristle not 

 strong. 



Sqnamulae whitish ; haltères yellow. 



Although it is stated above, in the generic description that in 

 this species the proboscis should be "short and genicnlate and with 

 the flaps not much prolonged" it is of great interest to record that 

 in a single spécimen of the 47 that I hâve examined the proboscis 

 is of an entirely différent type, being strongly genicnlate with the 

 apical portion as long as the basai portion (PI. I, fig. 15) and there- 

 fore resembling more the Tephntis group to which T. conyzae 

 Frfld. belong. In ail other characters this spécimen is entirely ty- 

 pical. 



This handsome species is fairly common ail over Egypt; I hâve 

 captnred it in ail the localities mentioned above for the three other 

 .-species and my dates extend from end of Jannary to end of No- 

 vember 1922. I very mnch suspect the larva to live on Zygojjhyllum, 

 but I am not able yet to state this definitely. T. avgvr h.-is 

 also been recorded from Persia and Algiers bv Dr. Th. Becker.
