33. The Bag-worm, Thyridop- 

 teryx ephemenefonnis. Haw. (Fig. 

 17.) Although we have no actual 

 record of its capture, or presence, 

 this insect doubtless occurs in Can- 

 ada. In some of the States ad- 

 joining the Dominion it has been 

 very destructive to a great many 

 kinds of fruit and shade trees, 

 among which is recorded the lin- 

 den. The habits of this insect are 

 remarkable. The caterpillar, as its 

 name suggests, makes a bag com- 

 posed of twigs or bits of leaves, 

 within which it lives. The female

moth is wingless, and soon after chrysalis;

which she made when a larva with eggs. The^e bags containing the eggs hang on the trees all 



winter, the young caterpillais hatching the following spring. 



34. The Oblique-banded Leaf-roller, Archips rosaccana, Harr. The larvie of this common 

 and widely distributed tortricine moth are very general feeders, and we have found them on 

 a great variety of trees and shrubs at Ottawa, the basswood being aniung the number. During 

 the past season they were particularly abundant on the apple, but did not do any serious 

 damage. 



35. Paraphia suhatomaria, Wood. On the 14th April last a single larva of this insect 

 with some apple leaves was received at the Division of Entomology from Mr. R. J. Messenger, 

 of Bridgetown, N.S. This caterpillar would not, however, eat apple in confinement, and after 

 almost ever) thing else had been tried we succeeded in getting it to eat basswood, on which 

 food we reared it to the perfect insect, the moth emerging on the 8th June. 



36. Paoniaa excaxatiis, S. & A. On several occasions we have collected in August, at 

 Ottawa, the larva of this hawk moth by beating the foliage. 



37. Apatela Americana, Harr. The cater- 

 pillars of this noctuid have also been beaten 

 trom basswood (Aug. 25) by the wiiter. The 

 larvfb feed on the foliage of a number of 

 other trees (Fig. 18). 



38. Ania Ihnbato, Haworth. A single 

 larva of this geometrid moth was found by 

 Mr. Harrington feeding on the linden at 

 Ottawa, and given to the writer, who bred it 

 to the perfect insect. 



39. Coleophora tilkefoliella, Clem. In 

 Packard's Forest Insects it is stated that the 

 larva of this species feeds on the leaves of 

 linden from the beginning to the latter pait

of May. Tlie larva is said to be dark, dull brown, the dorsal plates and head black. We have 

 never collected the insect in Ontario. 



40. LithocoUetis lucetiella, Clem. The larvte of this beautiful little ir.oth have been found 

 quite commonly on the basswood in some d stricts.
