 the apieal fourth of the wing, extends from just above R4 + 5 and 

 downwards aeross Ml to the lower Aving margin ; ail thèse three 

 indentations verygradually widen from their bases to the lower mar- 

 gin of the wing; the radio-median cross-vein is close to the médian

I hâve bred one adult of this species from the floral sjjikes of 

 Lavandula coronopifolia which I had collected in Wadi Hussein. 

 It very probably, however, also lives on Stachys aegyptiaca, upon 

 which plant it may commonly be found from February to June to- 

 gether with its closely allied species, S. dehskii in ail the wadis near 

 Helwan. I hâve captured it myself in February, March, April, May 

 and June lOth in the Wadi Hoff, Wadi Rashid, Wadi Hussein, 

 Wadi Rishrash as well as along the Suez Road, always on the 

 Stachys and also by "sweeping" the flowering spikes of Lavandula.
