three times. Allowance must be made as regards the 
accuracy of the above, deductions for a few days absence, as 
well as engagements, precluding the power of observation. 
In reference to the flowers especially frequented by the 
butterflies recorded may be mentioned :—In the early part of 
the season: wild hyacinth,—a favourite blossom for Io, 
Rhamni, Rape, Cardamines, and Phleas; fruit-tree blossoms, 
—lo, Polychloros, and Urtice; periwinkles,—Rhamni and 
Io. Later on in the year: Virginian stock,—Pieride and 
Janira; thistle blossoms,—Janira and Urtice; species of 
dead nettle in the hedge-rows likewise much frequented by 
Pieride. I may also state that the caterpillars of Vanessa lo 
and Urtice have been very abundant this year on the nettles 
in this parish and neighbourhood. I have already bred many 
specimens of the latter; those of the former are still in the 
pupa state. I subjoin the following dates :— 
Vanessa Urtice.—Butterfly on nettles; April 27th and 
28th, supposed period of eggs deposited. Caterpillars taken 
on same nettles; June, first week. Chrysalids; June 13th to 
June 25th inclusive. Butterfly; July 2nd to July 10th; the 
perfect insect emerging in numbers during the last three of 
days specified. 
V. Io.—Butterfly in neighbourhood of nettles; April 23rd 
and 24th, supposed period of eggs deposited. Caterpillars 
taken on same nettles; June 15th. Chrysalids; July 6th, 
7th, 8th, 9th, and 10th. A large number still in the larva 
state. 
In conclusion I have only to state that as regards the 
discovery of the caterpillars of Vanessa Io and Urtice, I have 
given the dates of the earliest found, and where I could more 
certainly connect them with the presence of the butterflies, 
which I had previously seen fluttering in the locality. I 
continued to find the caterpillars of V. Urtice up to the 
19th of June, and those of V. Jo up to the 3rd of July, and a 
few even on the 10th, on which I am writing.
