number of species in other families has been determined by Mr. 

 Guignard, who has made a fine collection of these very interesting 

 insects during the past two or three years. 



Lepidoptera. — In this attractive order a considerable amount of 

 work has been done, chiefly amongst the diurnals, although the noc- 

 turnals have not been altogether neglected, and many new and rare 

 species h?ve been added to our collections. A collection is exhibited 

 this evening of specimens of diurnal lepidoptera, all taken during 

 the year in this locality or bred from the eggs. The leaders cannot do 

 better than urge the members of the Club to take up the study of rear- 

 ing insects from the egg. The eggs of many species can be obtained with 

 comparative ease ; yet hardly anything has been done in this line, and 

 a fruitful field is open for workers. During the past year a commence- 

 ment has been made, and the results are exhibited to you to-night. 

 The exquisite specimen of Colias Eurytheme, winter form Keewaydin, in 

 the case was bred from an egs^ laid by a specimen of the summer form 

 Eurytheme so battered that it was hardly recognizable. At the same 

 time a family of twelve specimens of the common Clouded Sulphur 

 butterfly, Colias Philodice, were bred with this specimen for the sake of 

 comparison, and were compared daily with important results. This 

 family was chiefly of interest, because it showed conclusively that the 

 white form of female, occasionally found flying with the yellow speci- 

 mens, is merely a chance variety. Three of tlie twelve were very 

 fine albinos. This result of obtaining white females from a yellow- 

 female had not, we believe, been previously obtained. Other interest- 

 ing points as to the extent of variation were also demonstrated. 



Although an almost complete sei-ies has been collected we con- 

 sider it wiser to postpone for a time the publication of a list of our 

 diurnals, so that additional information may be acquired regarding 

 some of the species. 



Among the larger, or rarer, lepidoptera which have occurred during 

 the past season, eithar in the preparatory or perfect states, mention 

 must be made of the following species. Actias Luna was exceedingly- 

 abundant in the larval stage near Hull, over thirty caterpillars having 

 been collected in one afternoon, chiefly from the bitter hickory {Carya 

 amara). On oaks the larvae of C eratocampa pelluciJn were abundant.
