elongated heaps; the mine soon turns at 
nearly a right angle, and crosses over 
almost in a straight line to the next rih, 
along which it then proceeds for a short 
distance further; the mine then expands 
into a large greenish white blotch, which 
afterwards becomes brown, and which 
generally occupies the whole space be- 
tween the two ribs, from the transverse 
incipient mine to the edge of the leaf. In 
this blotch the excrement forms an un- 
interrupted black thread, twined into a 
thick coil, which is more slender than 
the previous excremental track, and only 
becomes very slightly thicker towards the 
margin of the leaf, where the windings 
are less close. 
“ The larva, entirely apodal, is three 
lines long, flat, and gradually narrower 
towards the tail end ; the thirteen seg- 
ments are separated by deep incisions; 
the last is particularly narrow, and ter- 
minates with two small points ; the colour 
is dirty white or yellow ; the three last 
segments only are tinged with reddish. 
The flat brown head is much narrower 
than the first segment; it is pointed 
towards the mouth, and has a dark brown 
spot on each side. 
“ As far as I can remember, the larvse 
quit these mines before the end of June, 
and descend to the earth, where they 
construct small oval cocoons, which, in 
proportion to the size of the larva, are 
extraordinarily small; the cocoons are 
formed of yellow or brownish web, of a 
leathery texture, and bedecked externally 
with grains of sand. When the larva 
casts off its skin I have not been able to 
observe. 
“The pupa is thick and short, not 
with a horny integument, but with a 
quite tender skin, as in Coleoptera, which 
allows all the parts of the perfect insect 
to be recognised as distinctly separated 
from one another; it is rusty yellow, the 
sheaths of the four separate wings black, 
reaching to the anus, beyond which the 
hind legs project. The entire appear- 
ance of the pupa reminds one strongly of 
that of a Cicada. The first imago made 
its appearance on the 20th of February, 
ten days after I had placed the pupse in 
a warm room.” 
Dr. Hofmann observes that Kalten- 
bach had already described one larva of 
this genus in a paper in the ‘ Verhand- 
lungen des naturhistorischen Yereines 
der preussischen Rheinlande und West- 
phalens,’ entitled “ Die deutscben Phy- 
tophagen aus der Classe der Insekten.’’ 
I should be very glad if any of my German 
correspondents could get me a copy of 
Kaltenbach’s paper. If it is unobtainable, 
perhaps Dr. Hofmann will be so good as 
to quote the entire passage relating to 
this Micropteryx larva in hazel-leaves, in 
an early number of the ‘ Correspondenz- 
blatt.’ It is too precious a morsel to be 
left concealed in an unknown periodical 
publication. — H. T. Stainton; Mar. 14. 
NATURAL HISTORY OF THE 
TINE IN A. 
We must again call the attention of our 
Micro-Lepidopterological readers to the 
prospects of the eighth volume of the 
‘Natural History of the Tineina’ (the 
sixth volume is now in the press, and 
the manuscript of the seventh volume is 
completed). 
For the eighth volume (which should 
appear in 1863) we propose to give 
twenty-four species from the allied genera 
of Gracilaria, Coriscibm and Ornix. 
At present we have the transforma- 
tions worked out of fourteen Gracilaria,
