Ir must be always a pleasure to an entomologist to name and introduce a 
new species about which there can be*no controversy, and I must confess that I 
should have been very glad to have found some such species in the series of figures 
which are illustrated in the accompanying plates. I find it, however, quite beyond 
my ability to separate the twelve varieties there given, unless they are divided into 
nine or ten species. Every one will, I think, agree that 27 and 32 are the sexes of 
one species, however much they may hesitate to follow me in placing all those now 
figured under the name of Euryta. Figure 29 is the only variety about which I feel 
the least hesitation, as it much resembles some broad-banded specimens of A. Esebria. 
My collection contains other examples, which differ as much from those figured as 
they do each from the other; two of these, exact copies of my specimens except that 
the black spots on the posterior wing of mine are more alike, are figured by the 
Felders. In the figure of Vestalis it is only necessary to alter the black spot near the 
costal margin of the posterior wing (which is lower down the wing than usual), and 
this species will agree with their A. Alcinoe and all the varieties which I have figured. 
The typical variety described by Linnzeus, under the name of Euryta, in the 
Banksian Collection, is an Acrzea, and altogether distinct from the Eurytus of Clerck, 
which is a Diadema. Godart evidently believed them to be one and the same species. 
Mr. Westwood has also placed them together m the “Genera of Diurnal Lepi- 
doptera.” * 
Cramer’s figure 2338 so completely represents the typical specimen in the Linnean 
Cabinet, even in the setting, that the drawing might have been made from it. His 
* Mr. Westwood thinks that when Linnzeus described his Acreea Euryta, he confounded it with 
Diadema Eurytus of Clerck, believing it to be the same species. He certainly quotes Clerck’s figure. 
His description, however, agrees with the Acriea in his collection, and does not agree with the Diadema 
of Clerck, which has conspicuous black spots on the anterior wing.
