P L AT YSAMIA GL0YER1. 
Secondaries. Color same as in primaries ; ornamentation same as in male, except the 
discal spot which is double the size. 
Under surface marked same as the upper; coloration same as in under surface of male. 
Habitat. Arizona. 
This species I have named in honor of that most indefatigable ot all hard working 
naturalists, Prof. Townend Glover, of Washington, D. C., who first showed me examples of 
it, which were said to have come from lower California, but as L. A\ eidemeyerii, Pam, 
Smintheus, and other northern Montane species were sent along in company with it, I ex- 
pressed my doubts regarding that locality, which have since been confirmed by my receiving 
a female example from Arizona. 
Of the distinctness of this species from P. Euryale, Boisd., (P. Calitornica Grote,) and 
P. Cecropia, there cannot be a particle of doubt, but what relation it may bear to P. Columbia, 
Smith, I am unable to say, (though the wide difference in locality convinces me they are dis- 
tinct,) as I believe no figure has vet been published of the latter species, and Prof. S. J. Smith’s 
types are all contained in some institution in Massachusetts, and the species must consequently 
remain a blank to the scientific world, until some one gives a figure of it. Apropos to this giv- 
ing descriptions without figures, T may say that we Americans certainly occupy a most unenvia- 
ble pre-eminence ; if we had more figures and fewer descriptions there would be, I have little 
doubt, more satisfaction and considerably less confusion among scientists. The idea ot ex- 
pecting anything short of the supernatural to identity a Lvesena, Hesperia, or any of the smaller 
noctuidee, by a mere description, is preposterous. W hy, even larger species cannot thus be 
identified. I would like to sec the Entomologist who could, by any description, identify or 
separate from each other Vanessa Poly eh loros, Californica, Xanthomelas, and Ichnusa — yet 
although probably sprung from the same root, they are different in appearance when placed 
side by side, and exist in localities widely remote from each other. I would sav the same of 
Van. J. Album and V. Album, or of many of the Coliades. Many and many a time have I, 
when a whole evening was wasted, trying with aching head to find out whether some little 
butterfly was something or something else, consigned the discoverer of the species in question 
to all kinds of unspeakable torments. Here is a sample of the result of this state of affairs, 
as shown by the latest synopsis of North American Butterflies, by AY. PI. Edwards : Thecla 
Humuli, Harris, is Melinus, Hub., Favonius, Bois. & Lee., and Hyperiei, Bois. & Lee., 
T. Edwardsii, Saunders is Falacer, Harris and Calanus, Grote & Robinson, while Calanus, 
Hub., is Falacer, Godt. T. Viridis, Edvards, is Dumetorum, Boisd. T. Henrici, Grote, is 
Arsace, Boise & Lee. Lyesena Anna, Edwards, is Cajona, Reakirt, Argyrotoxus, Behr, and 
Philemon, Boisd. 
The female of Colias Eurydiee has been in its time Gonepteryx Rhamni, Goneptcryx 
Lorquinii, and lastly Megonostoma Helena, Male ! and if the brilliant colored male had not 
been at last coupled to his plain spouse, heaven knows what she would not have been. 1 
might go on multiplying instances ad libitum, but until the descriptions of species are accom- 
panied by correct figures, every new species described will but add to confusion confounded.
