188 THE CANADIAN ENTOMOLOGIST. 



enumerate. Among the most valuable are the " Entomological Contri- 

 butions," by J. A. Lintner ; " Descriptions of Noctuidae," by A. R. Grote ; 

 " Food Plants of the Tineina, with Descriptions of New Species," by 

 V. T. Chambers, both published in the Bulletin of the United States Geo- 

 logical and Geographical Survey; "Manual of the Apiary," by A. J. Cook ; 

 on "Sexual Dimorphism in Butterflies," by Samuel H. Scudder ; also 

 several papers by the same author on fossil insects found in the Rocky 

 Mountains, and in the Tertiary Beds at Quesnei, in British Columbia ; 

 " Insects Injurious to the Cotton Plant," with many plates, by Townend 

 Glover ; " On the Butterflies and Moths of North America," by Hermann 

 Strecker. Several additional numbers ot Edwards' •" Butterflies of North 

 America " have appeared, each one rivaling or surpassing its predecessor 

 in the exquisite beauty of the plates illustrating the species described. 



The publications of our own Society have been creditably maintained. 

 Our annual report to the Department of Agriculture for the past year has 

 been very favorably noticed, and our Canadian Entomologist has been 

 issued regularly, its pages being well filled, chiefly with the records of 

 original observations. The contributors to our last volume numbered no 

 less than forty- five, and included the names of nearly every Entomologist 

 of note on the continent. During the year we have published two hand- 

 some lithographic plates, one on wood-boring beetles, illustrating eight 

 species ; the other, which is printed in colors, exhibits the full-grown larva 

 of that rare and interesting moth, Samia Columbia. Among the most 

 valuable papers I would mention those of W. H. Edwards, on the pre- 

 paratory stages and dimorphic forms of butterflies ; and one by the same 

 author detailing the notable discovery of secretory organs on the hind 

 segments of the larvae of Lycaena pseudargiolus, from which is discharged 

 a sweet fluid which induces the attendance of ants, who in return for the 

 sweets thus provided them, defend these larvae from their enemies. Our 

 pages have been enriched also by valuable papers on the Noctuidae and 

 Pyralidae, by A. R. Grote ; on gall insects and other subjects, by Dr. H. 

 Hagen ; on Tortricidae, by C. H. Fernald ; on Tineina, by V. T. Cham- 

 bers, besides many others, which time will not permit me to enumerate. 

 During the past three months we have published in three portions a 

 translation from the German of a very valuable paper by Dr. A. Speyer, 

 on the Genera of the Hesperidae, which paper, we trust, will be the means 

 of bringing about such a re-arrangement of the species contained in this 

 interesting family of butterflies as will be acceptable to Lepidopterists, and
