110 THE ENTOMOLOGIST. 
foregoing, but the long series in this collection is quite exceptional 
in this respect. The tone of colour varies considerably in differ- 
ent individuals, the usual dark markings being so intensified in 
some as to give the appearance of an almost black and white 
insect, while in others the greenish-brown clouding pervades the 
area of the wing to a considerable extent; but perhaps the most 
important forms of variation are due to modifications of the 
central band; this in some specimens is broad and complete, in 
others but little more than half the proportionate width; it is 
also sometimes widely divided below the middle; and lastly, it 
disappears, and is replaced by some more or less distinct grey 
clouding, this last form being known as var. albocrenata, Curtis. 
It is unnecessary that I should repeat his description here, but 
his remark with regard to ruptata, Hub. (= corylata, Thnb.),— 
““T have a remarkable variety that I took in Scotland, making an 
approach to the following,” 7. e. alboerenata,—applies well to 
some of the intermediate forms in this series. 
The remainder of the collection consists of the following, 
chiefly odd specimens, that call for little comment: Selenia bilu- 
naria (the largest male I ever saw), Boarmia repandata, Dasydia 
obfuscata, Zonosoma pendularia, Acidalia aversata (and the com- 
moner form without band, spoliata, Staud.), A. fumata, Fidonia 
carbonaria, and Coremia munitata (somewhat more silvery in tone 
than the usual Scotch form). 
Among the autumnal larve that were obtained are some of an 
Eupithecia that were beaten from juniper, which it is hoped will 
produce helveticaria or its variety arceuthata.

subtristata. ‘The older name must therefore be adopted for this 
insect.
