THE ENTOxMOLOGlSrS WEEKLY INTELLIGENCER. 
friends with the larvce of Tceniocampa 
Populeli I have still a number to spare, 
and shall be glad lo exchange them for 
ovae, larvae or pupae of other species I am 
in want of. I suppose this is one of the 
“unknown larvae” alluded to last week, 
though I believe several gentlemen have 
bred it.— Joseph Steele, High. Street,

Exchange . — Being desirous of breeding 
the following species, I shall feel very

will communicate their wants: —

NATURAL HISTORY OF THE 
TINEINA. 
Gepressaria Emeritella. 
The egg of this species is probably 
deposited in spring, but I am not aware 
that hybernated specimens of the imago 
have been observed. The larvae feeds on 
the leaves of the Tansy {Tanacetuin vul- 
gare) ; it draws one or two leaves to- 
gether, and constructs for itself a tubu- 
lar habitation, from which, however, it 
escapes on the slightest alarm. The 
larva may be met with in June and the 
first half of July, but towards the middle 
of July it is full fed, and then descends 
to the surface of the earth, where it 
undergoes its change to the pupa state. 
In about three weeks the perfect insect 
makes its appearance, and it may be met 
with during the months of August and 
September. 
Depressaria Olerella. 
The egg of this species is no doubt 
deposited in the spring by the hybernated 
female. The larva feeds from the middle 
of June to the beginning of July on the 
common yarrow {Achillea tnillefolium) ; 
it draws several leaves towards the stem, 
and fastening them there constructs a 
tolerably secure habitation, within which 
the full-fed larva frequently undergoes 
its transformation to the pupa state ; 
though sometimes I imagine it descends 
to the surface of the earth, to undergo 
its change there. At the beginning of 
August the perfect insect makes its ap- 
pearance, and is sometimes met with in 
the spring after hybernation. 
Depressaria Heydenii. 
From the time of year in which the 
larva of this species is found feeding, 
I entertain no doubt that the egg must 
be deposited in spring, and therefore the 
perfect insect must hybernate. The larva
