feeds from July to September in tbe 
green seed-capsules of Erylhrcta cen- 
taurea, eating out tbe contents and living 
well concealed; the protruding yellowish 
brown “frass” betraying, however, their 
presence. In collecting this species it is 
best to gather the plants and keep them 
in water for some time, as the full-fed 
larvae gradually leave the capsules in 
order to change, and the first Plumes 
are already on the wing, whilst some still 
remain in the larva or pupa states. 
Pterophorus microdactylus on Eupa- 
iorium Cannabinum. The larva lives 
from tbe end of summer till spring in 
the stems of Eupatorium Cannabinum, 
e.specially in the neighbourhood of the 
knots. Not unfrequently we find two or 
three larvae in one stem, which change 
to pupae in May, and furnish the perfect 
insects in the beginning of June, if not 
previously killed by the parasitic larvae 
of Apanteles lamgator. 
Cochylis phaleraiana on Eupatorium 
Cannabinum. I have obtained this 
beautiful Tortrix when breeding Ptero- 
phorus microdactylus, but only very 
sparingly. My colleague. Dr. Forster, 
has also bred the insect two successive 
years from wintered stems of Eupatorium. 
The larva consequently is a pith-feeder, 
like those of Cochylis Mussehliana and 
Zephyrana. 
Sesia tenthrediniformis, Lasp. {empi- 
formis,Yievieg) on Euphorbia cyparissias. 
According to a communication of Herr 
Koch, the larva of this insect lives in the 
stems of Euphorbia cyparissias. Unfor- 
tunately some larvae which I collected in 
the roots of this plant near Wiesbaden, 
at the beginning of September, perished 
on the journey hither. According to 
O. Wilde, the larvae may be found at the 
end of February in the old root-stumps, 
and the imago bred from them in May. 
[The foregoing extracts will show that 
this elaborate Memoir of Kaltenbach’s 
may prove serviceable to others besides 
collectors of Tineina. Tortrices, Ptero- 
phora and Sphinges being only a small 
portion of the other matter it contains ; 
Diptera, Hemiptera and Coleopteia are 
also fully noticed. 
We shall probably recur to Herr Kal- 
tenbach’s Memoir on another occasion.] 
OXFORD PHILOSOPHY. 
To the Editor of the * Intelligencer,'' 
Sir, — It has required but little Oxford 
philosophy * to discover that the curious 
birch-leaf larva you placed in my hands 
at the last meeting of the Entomological 
Society, and which, I see, forms the sub- 
ject of an article in your last week’s 
number, belongs to the Order Coleoptera, 
Family Curculionidw, Genus Orchestes, 
and most probably to the species Or- 
chestes scutellaris. 
I remain. 
Yours very truly, 
J. 0. Westwood. 
Oxford University Museum, 
July 8, 1861. 
* This I take to consist in a precise 
investigation of facts, and a determina- 
tion to regard as true only what has 
been satisfactorily proved to be so.
