THE CANADIAN ENTOMOLOGIST, 93 



a small butterfly which had just alighted on the bare road in front of us. 

 This I was delighted to recognise as Niphon. Having no nets with us, a 

 too near approach was only rewarded with the mortification of seeing the 

 coveted prize flit lightly up to the top of some high pine trees. Subse- 

 quent to this date the weather was cold and wet for some time, and I had 

 no opportunity to visit the locality until the 22nd of the month. On this 

 date the Ottawa Field Naturalists' Club organized an excursion to the 

 Chelsea Mountains for the purpose of entertaining the Fellows and Dele- 

 gates of the Royal Society of Canada, and consequently we were honored 

 with the presence of our worthy President, Prof. Saunders, who happened 

 to be in Ottawa attending the annual meeting of the Royal Society. As 

 we passed the locality for NipJwii on the way, the attention of all was 

 directed to the pines as we passed. It was the President's experienced 

 eye which detected the first examples ; three beautiful tempting speci- 

 mens were seen flying round the top of a white pine about 30 feet from 

 the ground and well up out of reach ; but none were obtained. 



Two days later, however, Mr. Harrington, Mr. Ami and I went out 

 again armed with a net attached to a long bamboo. Fortune favored us 

 at last. On the way out one female which had settled on the road was 

 taken. When we reached the grove of white pines (Pimcs strobus) where 

 the three specimens had been seen two days earlier, Mr. Harrington 

 climbed up to the top of the same tree and took two more, all in good 

 condition. Bordering the pine grove was a field in which a great deal of 

 the herbage was made up of Antennaria plantaginifolia in flower, and 

 along the edge of this field, close to the trees, nine more were taken and 

 two others seen. Highly elated at our success, we turned our steps home- 

 ward with twelve perfect specimens, eight '^ and four ^ . Two days 

 later I again re-visited the locality and met with a great disappointment. 

 The da)' was intensely hot and butterflies were very plentiful. On arriv- 

 ing at the field I saw with delight Niphon three or four at a time in every 

 direction, but my chagrin was great when on taking them one after 

 another, I found there was hardly a presentable specimen amongst them. 

 The locality is on the top of a hill, and for the past two days high and 

 boisterous winds had prevailed, and this must have been the cause of their 

 tattered state. Altogether, although a hundred could have been taken 

 with ease, not a dozen were found worth collecting. Nevertheless, I 

 boxed some females alive with the object of getting the eggs, and have 

 succeeded in getting thirteen. Under the microscope they are objects of
