THE ENTOMOLOGIST’S WEEKLY INTELLIGENCER. 
restricted on the Continent ; P. Ma- 
chaon and P. Acis are universally dis- 
tributed in Germany, where the former 
is a common garden and wood insect; 
and, with the single exception of Pam - 
philu Action, all our other local species 
are very generally distributed in Ger- 
many, though not occurring in every 
district. 
Dr. Dickie, at Aberdeen last month, 
suggested that there might be some 
peculiarity in the food of these local 
species; but, though Machaon is with 
us extremely partial in our Fens to 
Peucedanum palustre, yet on the Con- 
tinent it feeds indifferently on a num- 
ber of U m belli ferae, not disdaining 
even the common carrot. And that 
C'inxia should be almost confined to 
the Isle of Wight, when its larva feeds 
on the ribwort plantain ( Planlago lan- 
ceolate), — a plant common enough at 
Aberdeen and through all the inter- 
vening country, sufficiently demonstrates 
that it is not the restricted range of 
the food-plant which is the cause of 
these Butterflies being confined to areas 
of such small extent.

TO CORRESPONDENTS. 
F. II., Regensburg. — XI. duly re- 
ceived ; thanks. The grass appears to be 
Sesleria, but we much doubt whether the 
larva is Adsciiella ; notice the locality 
well and revisit it in April, as these larva; 
will probably not be fed up till spring.
