segment in the posterior wings with some black scales near the apex. 

 Veins of the anterior wings eight in number, the first and second 

 separate, springing from the base, the third from the posterior margin 

 of the cell, the fourth dividing into two branches, running from the 

 posterior angle of the cell to the posterior segment, the fifth coming 

 out near the anterior angle of the cell and running to the posterior 

 margin of the anterior segment, the sixth either two or three branched, 

 running from the anterior angle of the cell to the apex of the anterior 

 segment, the seventh from the anterior side of the cell, and the eighth 

 from the base. The cell distinct, closed, the transverse vein very 

 slender, somewhat arched. The veins of the posterior wings three ; 

 the first, two branched, running to the first segment, the second, also 

 two branched, running into the second segment, the third simply run- 

 ning into the third segment. No cell. — Entomologists' Monthly

O. pilosellce. — This species, which used to occur at Mickleham, was 

 lost for some years, until rediscovered in 1889 by Mr. Sidney Webb, 

 near Dover, It is at the the present time very rare, and, with the 

 exception of the i88g specimens, and an odd specimen or two in 1890 

 no other specimens appear to have been recorded as captured in 

 Britain for more than thirty years.

I have in my collection a Thuringian specimen sent me as this 

 species by Herr Hoffmann. I have also had the pleasure of seeing Mr_ 

 Webb's series of this species which he captured near Dover in 1889, 

 as well as specimens received by Mr, C. G. Barrett from Prof. Zeller 

 (the nomenclator of the species). It appears difficult to believe that 

 the Thuringian example is specifically identical' with Mr. Webb's 

 specimens, which are undoubtedly the same as Zeller's specimens in 

 Mr. C. G. Barrett's collection. Mr. South (" Entomologist," Vol. 

 XXII., p. 33) describes a specimen received from Dr. Staudinger which 

 appears to agree fairly with Mr. W^ebb's specimens, so that the 



*The above ought to have preceeded the account of O. distans on p. 141, but was 

 accidently misplaced.
