subniarginal spots and clouding arc iinperceptiblp. When 

 strongly marked, on tlie other liaud, tliere is often a clouding 

 of faint reddish-brown on tlie ai'ea of the ordinary central 

 band. In an example from tlie west of Ireland this band is

 series of small red-brown clouds ; the series Ijeyond the band

 dark dash running into the ajiex is continued as a cloud down 

 the hind margin. ^Ir. Sydney Webb has one in which the
