reported to me as having been seen near the Bridge 
of Allan. There is no reason why it should not 
occur here as it has been taken as far north as Edin¬ 
burgh. 
8 . Pyrameis Atalanta L. is sometimes not uncom¬ 
mon in the county, but is variable in the periods of 
its appearance—one year being abundant, and another 
year being very rare. It is found throughout the 
county and Scotland, specimens from which country 
are similar in all respects to English ones. 
9. P Cardui^ L. —This species has the same habits 
and distribution as the preceding, except perhaps that 
it is even more variable in the times of its appearance 
than that species, and that it is less oftener abundant. 
It occurs from the sea level up to the base of Ben 
Lawers. 
10. Pararga Algeria L. is a very local species and 
never appears to be abundant. It occurs on Kinnoull 
Hill and near Muirhall, and is double-brooded. Scot¬ 
tish specimens are larger than English. It has not 
been recorded from beyond the north of Argyleshire, 
—1858, May 6 ; 1859, July 8 ; 1860, May 1; 1869, 
April 26, Aug. 8. 
11. P. Megoera L. —This butterfly was formerly 
common near Perth. I say formerly, for I have not 
heard of any specimen having been captured since 
1860, in which year it was common. The series of 
cold summers following that year seem to have de¬ 
stroyed the species, though possibly (like P. Cardui) 
it may again put in an appearance. It is found in 
Scotland as far north as Argyle.—1858, May 24; 1859, 
May 28, Aug. 8; 1860, May 6, Aug. 9. 
12 . Satyr us Sernele L, is, though rather local, an 
abundant species where it does occur. Its favourite 
haunts are warm rocks, such as Kinnoull and Mon- 
creiffe Hills, &c., and in such situations it is very 
common. It occurs as far north as Sutherland, but 
does not seem to be found in the alpine parts of the 
country. Scottish specimens are slightly larger and 
darker than English ones.—1858, June 21 ; 1860, 
July 16 ; 1864, June 25 ; 1865, July 1. 
13. Ejpinepfiele Janira L. is a common species 
throughout the country, though it was rare in the
