320 Plumules or Battledore Scales. [^ou?nai,1)eTri£^ 
Zophoessa. — Found in one species. 
Euptychia. — Found in five species. See the singular form of 
tliat of Canthe, Plate XXXYI., Fig. 13, reminding us again, by its 
large lobes, of some of the Pieridm. 
Erebia. — Found in thirteen species. A type shown in Plate 
XXXYI., Fig. 14. 
Chionohas. — Found in seven species. A most interesting 
northern group, principally inhabiting Lapland and Norway. 
Lariommata. — Found in ten species, the forms of Msera and 
Megmra having been figured by Deschamps. 
Batyrus. — Found in thirty-two species. A type, Beroe, is 
shown on Plate XXXYI., Fig. 15. The plumule of Janira has 
long been known. 
Families XI., XII., and XIII. EuRYTELiDiE, Libytheid^, 
and Erycinid^. — No plumules found. 
Family XI Y. Lyc^enid^. — To these battledore scales I have 
before called your attention. 
Family XY„ HESPERiDiE.— None found. 
Having thus completed an account of observations already made, 
I annex a Table showing an approximate estimate of the number of 
species where plumules have been found to exist, and of the genera 
possessing them. Doubtless there is room for further research ; and 
I would urge upon all a prosecution of this interesting study. I 
doubt not that among the Ehopalocera there will be further dis- 
coveries made ; and the Heterocera afford an untravelled field to an 
observer. It will be very interesting to entomologists to learn 
whether any plumules are to be found among them, or any other 
class of scales serving for generic or specific classification.*
