In this month the first fresh Butterflies mingle with the hybernated species, but none 
of any rarity. 
The remarks on sallow-searching under last month also apply to this. That rarity, 
M. Carmelita, should now be sought for on the trunks of birch trees and palings 
near, and B. Prodromaria and C. Fagella on oaks, the former generally near the ground, 
not far from its Pupa case under the tree, from which it has not long emerged. By beating 
oaks we may find H. Fimbriana and D. Salicella. 8. Inconspicuella ma: sometimes be seen 
at rest on palings. I. Pectinea occurs among birch, and O. Piniariella, among fir trees. 
M. Purpurella, and others of that genus, may be obtained by sweeping the twigs of birch. 
In Perthshire the fine A. Nubeculosa is found in birch woods. The handsome B. Versi- 
colora is more widely dispersed, and the 6 are easily taken flying on fine mornings by the 
aid of a bred 2 in a box, though without such assistance you may watch their mad gambols 
for hours and fail to net a specimen. 
Hicifolia occurs at rest on moors. N. Trepida may sometimes be seen on trunks of oak 
at the end ofthe month in a warm spring. The Teniocampz visit laburnum trees, The 
Bupithecie fly just before dusk, The species of Micropte fly on sunny afternoons, and 
at other times may be shaken from oaks, &c. A. Cupre la flies in sunny weather over 
sallows. The long-winged '’, Caudella flies over spindle-bushes after dark, and together 
with the hybernated Depressari seem much commoner now than before hybernation. H. 
Be ad occurs only among Sedum telephium, Most of last month’s insects are 
still out. :
