and S. Ligustri(a\so pupae of the last-men-

A STRANGE PREDICAMENT. 
(See Intel. Vot. VIII. p. 165. ; 
Bucculatrix Artemisiella and Gnaph- 
aliella . — You are wrong with regard to 
these two species. The name Artemisi- 
ella was given by Wocke to his grey 
species, bred from Artemisia campeslris, 
which I first described and figured. This 
name cannot therefore be applied to the 
white species, although it likewise feeds 
on Artemisia campestris. This white 
species is certainly that which Treitschke 
described as Gnaphaliella, and Zeller 
after him, and it was figured by me 
under that name. To my knowledge the 
larva has not yet been found on Gna- 
phalium, but only the cocoon and the 
imagos. If there is a white species with 
truly unribbed cocoon, then is there a 
third species, which, if it indeed feeds od 
Gnaphalium, must receive the name of 
Gnaphaliella; and in that case our 
white species from the Artemisia must be 
named afresh. 
If Professor Zeller were again at work 
he would be able to solve the problem, 
but I have heard nothing from him since 
he weut to Meseritz. — Dr. Herrich- 
SchjEffek, Ralisbon ; Sept. 12. 
[In May, 1855, 1 visited Glogau, and 
on the 26th of that month made an excur- 
sion to the Stadt-wold, where I obtained 
many larvae of a Bucculatrix feeding 
in and between the leaves of Gnaphalium 
arenarium (see Eut. Annual, 1856, p. 129). 
Professor Zeller, who was with me at the 
time, told me these were the larvae of
