NATURAL HISTORY OF THE 
TIN El N A. 
The Genus Buccui.atrix. 
Since enumerating our wants in this 
genus (Intel, iv. p. 46) we have been 
supplied with larvae of B. niaritima and 
B. Artemisiella, and we have ourselves 
fallen in with larvae of B. Ulmella. 
We shall, however, vet be glad to 
receive larvae of Frangulella and Gnaph- 
aliella, as also of Boyerella, which we 
have never yet seen. 
The larva of Evonymi, Z. ( Rharnnella , 
H.-S.) is still, we believe, undetected, 
though its day of discovery can scarcely 
be far distant. 
The larva of Maritirna, like all the 
others of the genus, makes its cocoon in 
the peculiar, methodical, inverted way so 
circumstantially described by De Geer 
and Lyonet ; but that larva being larger 
than any of its congeners, the operation 
may be seen on a magnified scale, and is 
well worthy of attentive study by those 
who have opportunities of collecting that 
larva. 
A cocoon of this genus, arrested in 
process of development when half finished, 
would be a magnificent object for the 
microscope. 
The Genus Depressakia. 
Referring to our notice last year on 
this genus (Intel, iv. p. 53), we have only 
to observe that we still want every one of 
the larvm there mentioned, except three, 
Libannlidella, Hofmanni and Diclam- 
nella.

Propinquella, 
Subpropinquella,
