72 THE REPORT OF THE No. 36 



Field Chops. The writer has inspected a field in lake Saint-John district 

 where locusts ( Melcmoplus atlanis Riley) nearly swarmed especially on sandy 

 hills. Damages were reduced, to nothing as means of protection were applied in 

 due time. 



Floweks. Before closing these remarks I may mention the information given 

 me by a florist, which I was unable to confirm myself. This florist says that an 

 insect has destroyed a very high percentage of flower buds on dahlias. The insect 

 he sends as representative of the pest is nothing but the tarnished plant bug (Lygus 

 pratensis L. ) . I wonder if this' is the real offender, as I personally had no oppor- 

 tunity to look after his case. A large number of dahlia plants did not flower at 

 all and the whole trouble is attributed to this species hy the gardener. I would be 

 pleased to have the opinion of the memhers of this society on this point, if they have 

 already met with the same injury and if L. pratensis is really the cause of the 

 damage experienced. 



THE ENTOMOLOGICAL RECORD, 1920. 



Norman Criddle, Entomological Branch, Dominion Department 

 of Agriculture, Ottawa. 



The collecting season of 1920 appears to have been more varied than usual. 

 In British Columbia collectors report it as generally unfavorable, especially for 

 Lepidoptera. On the prairies there was not much variation from normal, except- 

 ing for the abundance of grasshoppers, while in the east insect life seems to have 

 been rather more prevalent than usual. 



Canadian entomologists will be pleased to learn that much progress has been 

 made in arranging the National Collection of insects, under the able curatorship 

 of Dr. McDunnough; as a result species in many families can now be determined 

 much more quickly and accurately than was formerly possible. 



It is gratifying also to know that Canadian collectors are recognizing the im- 

 portance of placing types in the National Collection where they can be seen at a 

 central point and where they are moreover comparatively safe from the dangers 

 to which private collections are subject. A particularly notable addition to the 

 Collection during the year was the acquisition of the Wolley-Dod Collection of 

 Lepidoptera, generously willed to us by the late owner. 



Our entomologists are again greatly indebted to specialists in the United 

 States and Great Britain for assistance in determining specimens as well as for 

 many other favors for all of which we express our grateful thanks. 



Among the publications! which have appeared during 1920, the following 

 should be of special interest to Canadian students. 



McDunnough, J. H. 'Studies in North American Cleorini (Geometridae). 

 Bui. No. 18, Dom. Entomological Branch, Ottawa. This work is primarily a gen- 

 eric revision of a group of moths that were previously nearly all lumped under 

 the genus Oleora. In it aTe described 16 new genera, and a gaaeric key is provided 

 on page j 1. The bulletin comprises 64 pages including eleven plates of illustra- 

 tions showing genitalia and other structural characters, in addition to a number 

 of species.
