VARIETIES OF PERONEA CRISTANA. 199 



Tolana, Desv. — The last curt description is not sufficient. 

 Tolana has a few — from three to five — short pale striae on the 

 inner third of the costa, of which we see no trace in desfon- 

 tainana, and there is a marked difference in the subsidiary 

 small tufts of scales towards the end of the wings, which we all 

 know are arranged two above longitudinall}^ (occasionally seen in 

 desfontainana, but always in tolana), and white in colour, and 

 three perpendicularly near the anal angle, also conspicuously 

 white in tolana, but if present at all, and that very rarely, fuscous 

 in the other moth. There may also be noticed a white streak 

 near the apex of the wing of tolana, never seen in its compeer, 

 and of course the distinguishing white vitta. The central tuft 

 of scales, too, is somewhat paler. It would seem then that the 

 comparison between the two moths by Desvignes was very super- 

 ficial, adopted only from a casual resemblance of the upper 

 part of the wing, possibly to avoid difficulties of expressing the 

 coloration. 



Masoniana. — Clark, n. ab., fig. 17. There were two speci- 

 mens under this name in the collection quite dissimilar, the 

 lower being an example of the ciirtisana of our cabinets, but the 

 ends of its wings are more mottled with white, which runs down 

 in a series of spots touching each other, so forming a line to the 

 anal angle, whilst the tuft is also pure white. It is labelled 

 " New Forest." 



The type specimen, however, is sufficiently described, except 

 in one or two minor particulars ; thus, writing of the darker 

 ends of the wings, paler clouds would better have expressed the 

 markings than white spots, and " the fine orange-coloured line 

 which extends along the margin towards the apex " should have 

 been omitted, as it refers to the coloration of the cilia alone, and 

 is not a wing marking. The pin is an ordinary white one, 

 slanting backwards, and no clue is given whence the specimen 

 was derived. A combination of unfortunate circumstances con- 

 nected with a newly named moth, which we have, however, 

 gathered was formerly in Dr. Mason's collection. 



Charlottana, Clark. — Unless this should prove to be identical 

 with the original ciirtisana, now lost to knowledge, we must 

 recognize it as a good variety, and the most beautiful of all. It 

 differs from those forms usually called ciirtisana by an absence 

 of the fascia from the costa before the button, by the white striae 

 and paler clouds along the costa, and the substantial reddish 

 orange streak from the base to the central tuft, which under no 

 conditions could possibly be called a " faint fulvous one." A few 

 specimens only are known. 



Giunpiana, Clark. — Specimens have hitherto been incor- 

 porated with our series of subcapiicina, more uniformly sprinkled 

 with grey and white, of a smoother aspect, and wanting the two 

 white square blotches towards the hind margin, whilst the
