388 Mr. J. J. Walker's notes on Lepidoptcra 



which are frequently stripped of their leaves by the 

 prettily-coloured larvae. It also occurs plentifully at 

 San Pioque, Esmir, &c. ; in fact wherever there are ash- 

 trees. The moths of the first brood, appearing in 

 April, are much larger than those of the second brood, 

 on the wing in July. 



Selidosema plumaria, W. V. — Common throughout the 

 summer and autumn at Campamento and San Roque, in 

 dry bushy situations. Very much smaller than speci- 

 mens from the South of England. 



Thamnonoma gesticidaria, Hiibn. — A not uncommon 

 species in the cork-woods in May and June ; easily dis- 

 turbed by day. 



Fidonia plumistaria, Vill. — This handsome and con- 

 spicuous Geometer is not rare in some heathy localities 

 in the cork-woods, Hying in the hot sunshine in April ; 

 also on the summit of the Sierra Carbonera, where, in 

 1889, I met with it as early as March '26th. 



Gnophos resp)ersaria, Hiibn. — Occasionally found in 

 dry stony spots in the cork-woods in June. I have also 

 seen it on the Rock.

 Gibraltar, where it comes to the gas-lamj)s in October.
