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 lo, 

 Rhamni, Rapae, Cardamines, and Phlaeas ; fruit-tree blossoms, 

 — lo, Polychloros, and Urticae ; periwinkles, — Rhamni and 

 lo. Later on in the year : Virginian stock, — Pieridae and 

 Janira ; thistle blossoms, — Janira and Urtica3 ; species of 

 dead nettle in the hedge-rows likewise much frequented by 

 Pieridae. I may also state that the caterpillars of Vanessa lo 

 and Urticae 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 UrticcB. — 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. lo. — 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 lo and Urticas, 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. Urticae up to the 

 19th of June, and those of V. lo up to the 3rd of July, and a 

 few even on the 10th, on which I am writing.
