remarks that he is in doiibt as regards this statement owing to the

Kaltenbach gives as food plant îor this species Son chu s a rvensis, 

 Tragopogon, Podoapermnm, and Apargia sp. 



In Egypt the food plant is unknown. T. tessellata is not com- 

 mon. I hâve up till now captured 6 spécimens only, four maies and 

 two females from the Mariout district, 5 and 21. IV. 1921, and 

 Becker had captured one pair in Alexandria in May 1899, 



T. tessellata is knnwn in Europe and has been recorded from 

 Siberia, Chinese Tnrkestan. Algeria. Morocco, Madeira and Canarv 

 Islands and from the Oriental Tibet.
