The wiiigless female moths of the canker worm Anisopteryoe 

 pometaria were very plentiful during ' September and October, but no 

 appreciable amount of damage has been observed in this locality from 

 this cause. 



On the whole, the season was a fairly good one for Lepidoptera. 



DiPTERA. Anthoniyia radicum, the Turnip-fly, was noticed as com- 

 mon, and as being destructive, while the Radish- fly ^IniAowt^/ia ra/>Aa?it, 

 Harris, (possibly identical with the foregoing) was particulary abun- 

 dant, and in some localities almost entirely destroyed the crop of 

 radishes. These are small greyish flies, somewhat resembling a diminu- 

 tive house fly. 



Some locust trees on Nepean street were badly infested by the 

 larvae of Cecidomyia robinice in July. The eggs are laid along the 

 edges of the leaflets, and the irritation pi'oduced by the young larvae 

 causes the edge of the leaflet to curl over and swell up. Several larvae 

 were found on each leaflet, and the appearance of the graceful foliage 

 was very sadly altered. The pupa state is also passed under the rolled 

 portion of the leaf, and when the fly is ready to emerge the pupa 

 works itself partially out at one end of the flap in order that the fly 

 may make its appearance unrestrained. 



CoLEOPTERA. In this order, work has been so far advanced that 

 Mr. Harrington has been able to prepare for publication a list of the 

 beetles found in the vicinity. A visit was made to Ottawa in July by 

 the late Dr. LeCoute, for the express purpose of examining any local 

 collections of Coleoptera, and of meeting those interested in entomology. 

 Unfortunately, two of the leaders in this branch were absent, and were 

 thus depiived of the pleasure of meeting that distinguished entomolo- 

 gist. Although Dr. LeConte's health had been failing for sometime, 

 the tidings that he had died on 15th November came unexpectedly to 

 most entomologists, all of whom felt that in his death entomology had 

 sustained the loss of her most experienced and eminent student and 

 teacher. 



A great number of interesting species of beetles were taken during 

 the year, including many not previously found, but mention can only be 

 made here of a few species.
