mens, and Italian examples presented by Dr. Leach have 

 also ferruginous costae, the other part of the wings being 

 almost without markings ; the latter specimens, too, seem a 

 trifle larger. 



I anxiously await the fulfilment of M. Guenee's kind 

 promise to forward me the typical osseata. 



Ebulea catalaunalis, Dup. (Fig. 4), 



At page 152, vol. iv. Entomologist's Monthly Magazine, 

 Mr. W. C. Boyd thus writes, " I captured it in our garden

 Nascia cilialisj Hiib. 



This species at first sight is not very dissimilar from

 imagines a small sharp and narrow-winged N. cUialis, a 

 much better idea of it is gathered. Owing to the paleness
