In this list none but tliose marked with an asterisk call for 

 any remark ; the coloration of the others is similar to that of the 

 ordinary Scottish type. 



Pieris brassicce. — It is doubtful whether this species is indi- 

 genous; it has probably been introduced with the cultivated 

 Brassicacecs. 



Chortohius Davus. — The Orcadian specimens resemble in 

 colour those from Rannoch. 



Lyccena Icarus. — The specimens are large, measuring as much 

 as 1 inch 5 lines; an unexpected fact. 



Hepialus humuU. — It is noteworthy that none of the specimens 

 taken approach in the slightest degree the coloration of the variety 

 Hethlandica, but all are quite of the ordinary normal type. 



Chelonia plantaginis. — Here, as in the Shetland examples of 

 this species, the colour of the upper wing is of a very light straw- 

 colour in some specimens. 



Larentia didymata. — The females of those taken are of an 

 unusually light colour. 



Emmelesia albulata. — This insect which, both in the Shetlands 

 and Hebrides, varies so much from the normal type that I have 

 deemed those from each group of islands worthy of a subspecific 

 name, appears in the Orkneys of the usual colour. 



Eupithecia venosata. — The leaden grey ground colour of this 

 insect, as found in Shetland, does not appear to extend to those 

 taken in the Orkneys. 



Ypsipetes elutata. — The specimens are very variable ; some 

 extreme aberrations have the ground colour of the wings black, 

 with very decided red bars.
