thoroughly wash out the jars with cold water every day. If, however, a caterpillar has 

 spun a web on the side and is hung up to moult, it must not be disturbed. In chang- 

 ing the food it is better not to remove the caterpillars from the old food, but having 

 placed the new supply in the jar, cut off the piece of leaf upon which they are and drop 

 it into the jar. If they are not near a moult, a little puff of breath will generally dis- 

 lodge them. Some caterpillars, as Papilio Turnus, which spins a platform to which it 

 retires after feeding, can best be fed upon a living tree out of doors, but must be covered 

 with a gauze bag to keep off enemies. A piece of paper should be kept attached to each 

 breeding jar or cage, upon which regular notes must be taken at the time, giving the dates 

 of every noticeable feature, particularly the dates of |the moults and the changes which 

 take place in the form and colour at that time. 



The following is a list of Diurnals, of which I have seen specimens, taken at 

 Nepigon. Some of the species were only taken by one collector, but most of them by all 

 of us. The following record is of Prof. Macoun's collection, made in the last week of 

 June, 1884 ; Dr. Bethune's, in the third week in August, 1888 ; my own in the last week 

 in June, 1887, the first week in July, 1888, and the first week in August, 1886. The 

 collection made in the first week in July is of course the trip above recorded, when I had 

 the able assistance of Mr. Scudder : 



Papilio Turnus, L. — July — Eggs laid freely on aspen. 



rieris Napi, Esper. Winter form Oleracea-hiemalis, Harr. Bred from eggs laid in 

 1887, by the next form. 



Pieris Napi. Summer form Oleraceacestiva. Bred from eggs laid by above form 

 upon Arabis perfoliata. 



Colias Eury 'theme, Bd. Summer form Eurytheme, Edw. 



Colias Eurytheme, Bd. Winter form Keewaydin, Edw. Of 36 eggs laid by the form 

 Eurytheme, which I brought to maturity this summer, 33 were Keewaydin, 2 Eurytheme^ 

 and 1 questionably Ariadne, Edw. 



Colias Eurytheme, Edw. Winter form Eriphyle, Edw. Not uncommon ; eggs laid 

 upon white clover. 



Colias Philodice, Godt. — Uncommon. 



Colias Christina, Edw. One female taken by Dr. Bethune, identified by W. H. Edwards. 



Colias Interior, Scud. — Abundant in July and August, particularly in blueberry 

 barrens ; certainly single brooded ; females lay after being caged on white clover for a 

 few days, but the young larvae (over four dozen) would not eat this plant. Two beauti- 

 ful albino females were taken. 



Danais Archippus, Fab. — Two remarkable wrecks, with only fragments of their wings, 

 were taken on 9th July. 



Argynnis Cybele, Fab. — August. 



Argynnis Aphrodite, Fab. — July, August. 



Argynnis Cipris, Edw. Some specimens taken by Dr. Bethune have been given this 

 name by Mr. W. H. Edwards ; they resemble Aphrodite, but the brown area beneath 

 hind-wing is more mottled in Cipris, not so solid as in Aphrodite, yellow showing in 

 between the nervures. Mr. Edwards has bred this species from the egg and says that 

 while the larva of Aphrodite is chocolate brown, when full grown, that of Cipris is 

 mottled with brown and yellow, and is one of the gayest larvse among the Augynnidw. 



Argynnis Atlantis, Edw. — Abundant ; July, August. 



Argynnis Electa, Edw. — First taken here by Prof. Macoun. It is a smaller species 

 than Atlantis, lighter in colour, and some specimens seem to resemble the western Lais* 

 This is also taken in Colorado, and its occurrence here is remarkable. 



Argynnis Myrina, Cram. — Abundant ; eggs laid on 10th July hatched and hiber- 

 nated at once, without feeding. 



Argynnis Chariclea, Schneid. — This is a late species. Dr. Bethune took two per- 

 fectly fresh specimens, 21st August. It is abundant at Port Arthur, 65 miles farther 

 west, in the beginning of September. Identified by Mr. W. H. Edwards. 



Argynnis Bellona, Fab. — Abundant; a handsome form, much darker than the 

 usual one. A very fine melanic variety was taken on 2nd August, 1886.
