Hecatera serena W. V. Several additional localities are 

 recorded for this pretty species. Doncaster, single 

 specimens in different years [H.H.C.) ; Drewton Dale 

 in 1893 {W. Johnson) ; Hull in 1897 and 1900 (/. Porter). 



Polia chi L. Another species which varies greatly in the 

 Huddersfield district, and where it shows a strong 

 melanic tendency. The darkest form, of an almost 

 uniform dark olive-lead colour, was first found near 

 Lockwood in 1890 by Mr. S. L. Mosley, since which 

 time I have taken it repeatedly on the walls close to 

 my house in the Meltham district, but it does not yet 

 seem to be recorded from any other locality ; with it 

 the variety snffusa Robson (first described from Bradford 

 specimens, where the form is also common), the variety 

 oUvacea Steph., and other forms occur {G.T.P.). Mr. 

 Cockayne records the var, olivacea from Sheffield ; but 

 Mr. Corbett says that a dark form is hardly ever seen 

 at Doncaster.
