traversed by three tawny fasciae, which 
naturally are scarcely visible in the dark 
portion of the wing, but are very con- 
spicuous on the pale inner margin, where 
the first tawny blotch lies almost at the 
base, the second obliquely placed before 
the middle, and the third and most con- 
spicuous is perpendicularly placed beyond 
the middle; on the fold these bands are 
intersected by some stout black dashes ; 
beyond the third tawny fascia is the pale 
hinder fascia, which is nearly white, 
broadest on the costa and rather sharply 
angulaled ; the apical portion of the wing 
is blueish black, dotted with whitish round 
the hind margin ; costal cilia dark grey ; 
cilia of the hind margin whitish, with 
the bases grey and a grey line towards 
the tip. Posterior wings grey, with the 
cilia of the same colour. 
The larva which probably belongs to 
this species feeds on the Lylhrum sali- 
caria in June. It is active, attenuated 
at both ends, of a dull reddish chocolate- 
colour, with a purplish tinge, with the 
head black, and a whitish spot on each 
side of the third and fourth segments ; 
the anal segment bears a black plate. 
The ensuing summer will probably 
not pass away without Mr. Brown again 
meeting with this larva, and a more 
critical examination of its habits. 
Should any important observations be 
made respecting this species I shall be 
happy to make them the subject of a 
subsequent notice. 
NATURAL HISTORY OF THE 
TINEINA. 
The Genus Gbacilaeia. 
I have already spoken of the genus 
Gracilaria, which will form the principal 
portion of the eighth volume of the 
‘Natural History of the Tineina’ (Intel, 
vol i.x. p. 1117), and I now proceed to 
discuss the desiderated larvae in that 
genus. 
These are thirteen in number; the 
seven first belong to the group of larger 
species, and the last six to the group of 
smaller species. The larvae of the first 
group construct cones, or, as in the case of 
G. elongella, roll up leaves longitudinally; 
the larvae of the second group only rarely 
make cones, as in G. Phasianipennella 
and G. aurogutlella ; more frequently 
they make flat mines, as in G. omissella 
and G. Ononidis, or like G. Limoselta, 
they may construct a very Lithocolleti- 
form mine. 
I proceed now to notice all that is 
already recorded respecting the known 
larvae, and to indicate the habits, &c., of 
those species of which the larvae are still 
unknown to us. 
1. Populetorum. Of this species Zeller 
remarks (Linn. Ent. ii. p. 331), “Re- 
peatedly bred by Fischer-von-Rbsler- 
stamm in Bohemia, from larvae on aspen 
and birch, which seemed extremely like 
the larvae of G. StigmatellaP Frey ob- 
serves (Tineen und Pteroph. der Schweiz, 
p. 233), “ The larva is double-brooded, 
occurring in J une and August on birch 
and aspen. I have bred it from both 
these trees, but have unfortunately neg- 
lected to describe it.” Herr Schmid, of 
Frankfort, in his manuscript notes, has — 
“ Larva in rolled leaves of birch ; full fed 
at the end of July.” 
Cones on poplar leaves I have often 
found, but they have alw'ays disappointed 
me by producing, instead of this species, 
G. stigmatella. Though the fact is not 
stated, I believe that G. Populetorum 
does construct cones. 
2. Rujipennella. Of this Fischer-von- 
Roslerstamm observes, in Treitschke’s 
work (ix. 2, 199), “The fourteen-footed 
larva is yellowish, or glassy, .sometimes
