LEPIDOPTERA OF THE OUTER HEBRIDES. 27 



something new, a careful examination of the lines and other 

 markings prove it to be a local form of M. sociata. The wood- 

 cut of the male insect here given will convey a better idea of 



this Hebridian form than the most elaborate description. I 

 would propose that this form should be known as var. uhscurata. 



Mchtnippc movtanata. — Some of the specimens are more or 

 less silvery white in colour of ground ; others have the band 

 interru])ted below the middle, and in one or two examples the 

 band is represented b}^ a dot or small patch of dark colour on 

 the costa only. 



CamjjtograDima hilijieata.— 'Reien-ing to the Hebridian form 

 of this s})ecies (Entom. xiv. 218), Mr. Jenner Weir says, "The 

 primary wings, though not strictly grey, have the appearance 

 of being washed with that colour." This feature is forcibly 

 exhibited in the specimens brought from Lewis last year, 

 which may be briefly described as follows : — Ground colour pale 

 ochreous, abundantly sprinkled with brown atoms, and marked 

 with numerous dark brown zigzag lines. These, together with 

 three white lines and the pale ochreous ground, in conjunction 

 W'ith the dark brown ornamentation, give the primaries a greyish 

 brown appearance. The hind wrings appear golden brown, with 

 a number of darker brown lines most closely approximating 

 from the middle to the base of the wing. As is often seen in 

 the type, the space between the second and third white lines on 

 the fore wings is more or less completely filled up with blackish 

 scales. 



Although Emmelesia alhulata was not uncommon, no example 

 of the white variety hehridium was seen by Mr. Mc Arthur in 

 Lewis last year.
