122 THE REPORT OF THE No. 19 



My, with a short round reddish body, belonging to the hymenoptera. At 

 Ottawa we have found these galls irregular, smooth and potato-like rather 

 oftener than elongated as shown in the figure. The only suggestion in the 

 way of a remedy is to cut out the infested portions of the plants.

Tortrix alhicomana, Clem. The small caterpillars of this well known 

 little Tortrix moth were very abundant and destructive to the leaves of Jap- 

 anese Rose at Ottawa during the past summer. They were particularly 

 abundant about the middle of June and moths were flying in large numbers 

 around the bushes on July 8, on which date Dr. Fletcher collected many 

 specimens. 



Ar chips pifrpurana, Clem. Several specimens of the larva of this com- 

 mon, rather small, moth, were found at Ottawa by Dr. Fletcher during the 

 past season in his cultivated beds of wild violets. No serious injury was done 

 to the plants and the specimens when discovered were removed by hand. 



The Hoary Plume, Pterophorus Tnonodactylus, L. During the past 

 season at Ottawa the small green caterpillars, much the same colour as the 

 leaves of their food plant, of this plume moth were found to be very destruc- 

 tive to the Minor Convolvulus. These larvse which were most abundant in 

 September were found to be eating the flower buds and leaves at the tips, 

 entirely preventing the plants from developing any flowers. Associated also 

 with this species was the tineid BedelUa somnuIenteUa, Zell, which helped 

 to some extent in the injury. 



Leaf Miner in Leaves of Lonicera. During some seasons at Ottawa 

 the leaves of one of the honeysuckles, Lonicera fulgens, have been mined 

 by a small lepidopterous larva, which in 1901 we reared to the perfect state, 

 and which has been identified by Mr. August Busck of the U. S. Bureau of 

 Entomology, as Lithocolletes fraqileUa, F. & B. The larva makes a con- 

 spicuous blotch-like mine in the leaves, and on some foliage examined there 

 were two or three mines in the same leaf. In 1901 the larvre were first noticed 

 about July 20 and by August 5 had pupated.
