THE YOUNG NATURALIST. 



four months sojourn in "Unst," in the summer of 1884, were not seen at all 

 this summer, or if seen were in greatly reduced numbers. 



Thus Hepialus humuli and its varieties were smaller in size and few in 

 number, though the variations are well pronounced in his captured specimens, 

 but wanting in the brighter reds, the markings being browner ochreus than in 

 1884, the species was not abundant— either type or variety in 1886. The 

 specimens taken have a decided tendancy to dull smoky under wings, males 

 with ochreus buff upper wings, often entirely wanting in depth of red mark- 

 ings, the white males have a tinge of lemon yellow upon them, but are almost 

 without the bright reddish-yellow cillia, so conspicuous in some of the 1884 

 specimens. 



H. velleda. — Abundant in 1884, only two specimens seen in 1886, these are 



beautifully and distinctly marked, but small. 

 Grammis. — Small, inclined to var. Hibernica, only three specimens obtained. 

 Furva. — Bred from larva found under stones and clods, on the cop fences, 



fine and dark. 



Festiva (varieties.) — As variable in size as it is in colour. Size from one inch 

 two lines, to one inch five lines. Colour from deep dull ashey greys, to 

 dark rich red browns. Some specimens with rhomboidal marks (dark) 

 between the well pronounced stigmata, and distinctly banded, others 

 without a marking of any kind observable upon the dark rich brown 

 wings, some specimens reminding us of Brunnea and others of Bella. 



Exulis. — Passe but large and variable in colouration, from light suffused 

 yellowish-drabs, to rich cold browns, with broad band, edged with yellow 

 ochre, stigmata obsolete, to distinctly outlined with yellow and white. 



Oculea.*— Large variety L niger, Haw. Scarce. 



Abjecta. — Dull drab without markings. 



Montanala. — Abundant in 1884, only three species seen in 1886. 



Immanata. — Only one specimen seen in 1884, taken freely in 1886. Vari- 

 able in size and markings, from dark rich brown, to light marmorate 

 specimens. 



Mmitata. — Scarce, but all fuscate specimens. 



Porphyrea. — Dull ashey specimens, few seen or taken. 



Glariom. — Two intermediate specimens, variety intermedia of my collection, 



all the rest of the grand series are as dark as Erebus, variety Hebriacoides 



of my cabinet. 



Em. Albutata and var. Thule (Weir.) — Finer than in 1884, and the variety 

 retaining the full size of the typical specimens. The series running 

 from rather white strong banded forms to dull dark cinereous fuscate 

 specimens, without perceptible markings, not common this season.
