 example (a^), is a variety in which a black central shade is 

 very evident. 



ACIDALIA OSSEATA, S. Y. 



It appearing that we have two species nnder this name in 

 our cabinets, and that interjectaria is the one which has 

 hitherto been known to us by the name of osseata (vide de- 

 scription in Stainton's Manual), the true osseata (as well as 

 i7iterjectaria) is now admitted to our lists upon the authority 

 of Mr. Doubleday, who thus writes concerning it at p. 161, 

 vol. iv. Ent. Mo. Mag. : " Acidalia osseata is rare here, and 

 I only know of one spot where it occurs. Specimens taken 

 a few years since, which were evidently very fresb, had the 

 costa decidedly ferruginous; but this colour faded soon after 

 they were dead, as it does in some EupitliecicE, &c. The 

 ground colour of the wings was also yellower than in any 

 specimens oi interjectaria that I have seen." 



'' The late J. F. Stephens mentions the red costa of osseata 



in his ' Illustrations,' but, as is well known, many of his 



descriptions were copied, without acknowledgment, from the 



works of continental authors."

M. Guenee has stated very decidedly that in osseata the 

 costa is always " rouge^^ a colour which he likens to that 

 of an English penny postage-stamp or thereabouts — some- 

 what that of the ground colour of Syria auroraria in 

 point of fact. But still in the National collection (although 

 two other species are mixed up with osseata) specimens 

 purchased from the late Mr. Becker, and coming from 

 Germany, though not unlike mteTJectaria are certainly 

 brighter (say tiger-coloured) on the costa than our speci-
