previously recorded by Mr. Lyman, but the mode of pupation was slightly different from 

 that described by Messrs. Lyman and W. H. Edwards, the chrysalis being surrounded by 

 several spans of silk in the same way as had been observed by the speaker in the case 

 of E, Discoidalis. E. Epipsodea is an abundant species on the prairie from the west- 

 ern borders of Manitoba through the Rocky Mountains to the interior plateau of 

 British Columbia. It was seen in hundreds on the prairies in the early part of last 

 July. 



Heliothis armiger. A specimen bred from a green larva found feeding upon ger- 

 aniums in a greenhouse, late in the autumn of 1898, the moth of which had emerged in 

 the summer of 1899. 



Chinobas Macounii, eggs were shown which were laid by a female among the thorns 

 on the dead twigs of a wild rose, at Nepigon. The bush was standing in full sunlight 

 on a sandy bank and no plant of Carex or grass could be found within 10 feet. The 

 female was seen to lay three eggs all on the dead twigs. These hatched in the ordinary 

 time of 15 days. 



Chrysophanus Thoe. Full grown living larvae were shown, reared from eggs laid 

 in confinement late in August. Of about 40 eggs half had hatched, but in nature it 

 was thought by the bpeaker that as a rule the eggs did not hatch until the following 

 spring. H e had discovered that the females laid their eggs not on the seed pods of the 

 dock, as had been previously thought, but low down on the root leaves and at the base 

 of the stem, where they would be covered up with snow during the winter. Many eggs 

 were found on plants growing in the water, and within an inch of the surface. The 

 larva? during the three moults, as well as the beautiful green and pink pupae, were 

 shown, also brown pupae and a dipterous parasite (Exorista confinis). Larvae and eggs 

 had been found on Rumex orbiculatus, but larvae fed readily on all docks offered except 

 Rumex obtusifolius. 



A beautiful collection of inflated larvae, prepared by Mr. C. H. Young, of Ottawa, 

 was exhibited, and, the value of this method of preserving a permanent record of 

 larvae for study was urged. Mr. Arthur Gibson, Assistant in the Division of Entomo- 

 logy, had also prepared some nice specimens, which were exhibited. 



Lycoena Anna — A fine series of this rare species was exhibited with the larvae and 

 pupae. Almost full grown larvae had been found on the 8th of August last at a height 

 of 7,000 feet on Mount Che-am, B. O. The larvae are green, and feed on the leaves of 

 lupins. The interesting discovery was made that the larvae when full grown crawl 

 down the stem and burrow down to pupate, from an inch to two inches beneath the 

 surface of the ground, as a rule following the stem and remaining attached to it. Five 

 females and three males were exhibited. These showed considerable difference in the 

 markings of the lower side. 



Benacus griseus — A specimen of this large water-bug, taken at Toronto, was 

 shown, and the difference between this species and Belostoma Americana pointed out. 

 The members were asked to examine all large water-bugs seen beneath electric lights, so 

 that the range of the two species might be ascertained. Although songht for carefully at 

 Ottawa, Benacus had never been detected there. In Benacus there is no deep groove 

 down the middle of the cushion-like area on the front raptorial claws. 



The Pea Aphis, Nectarophora destructor Jnsn. (n. sp ) Specimens of the Destruc- 

 tive Pea Aphis, together with three parasites, were shown, and a statement made as to 

 the injuries inflicted by this pest during the past summer. Colonies had appeared in 

 various places from the Maritime Provinces to the western portions of Ontario. 



On motion of Mr. W. E. Saunders, seconded by Mr. Balkwill, it was resolved that 

 the thanks of the Society are due and are hereby offered to Dr. Fletcher for his kindness 

 this year, and on many previous occasions, in presenting a number of valuable insects to 

 the Society's collection.
