146 ENTOMOLOGICAL NEWS. [May, 



City, a place called Fox Chase. You all know that great desire 

 to possess what we do not have, which is so strongly developed 

 in the enthusiastic naturalist and collector. We wanted "the 

 orange tip," and we wanted it badly. The time to look for it 

 was in, the Spring, when all nature was smiling and budding into 

 life again. It was the time when the great shad seine was being 

 hauled in, and we frequently watched this interesting process 

 while looking for the butterfly on the white flowers ( Cerastium 

 arvense) which grew along the river bank. This locality was 

 collected over for a number of years in the early Spring, but 

 without success. It was in the year 1889 that at last we were 

 rewarded; it was the 6th of May, and the day was still, clear and 

 warm. Two specimens were taken: one was beautifully fresh and 

 and not long from the chrysalis and the other faded and torn. 

 We were paid for our trouble at last, but the reward was not 

 very great, yet we were happy in having obtained the species in 

 our own territory. The captured specimens were females, and 

 the female lacks the orange tip to the wings, being entirely white. 

 A few years after (1892) we succeeded in discovering a locality 

 that has since given us our supply of this species. Having a num- 

 ber of botanical friends who went out on weekly excursions 

 around the surrounding country, we asked one of them who was 

 a good observer of such things, to keep a lookout for this insect. 

 He reported seeing the species in some abundance near a place 

 on the Perkiomen Creek called Arcola. This is twenty-eight 01 

 thirty miles from Philadelphia, and the train leaves very early in 

 the morning. Of course we determined to go for them the very 

 next day if the weather was suitable. Arising early in the morning 

 we found the day everything that need be desired. The money 

 invested in an excursion ticket, would have paid for the NEWS 

 for a whole year, but we were willing to take some chances on 

 the result, even if it became necessary to make an assignment 

 afterward. The ride was an interesting one ; we passed much 

 historic ground, including Washington's headquarters at Valley 

 Forge. We changed cars, taking the little narrow gauge rail- 

 road that runs along the picturesque Perkiomen. It was the 

 morning of May the gth, 1892, that this little trip was taken, and it 

 was nine o'clock in the morning when we stepped off the cars at 

 the little station at Arcola. Our net was gotten in order; cyanide 

 jar in readiness and the chase began. The old bridge was crossed,
