short note about it on page 355 of Volume V, Insect Life. 

 There seems to be but one record of a similar attraction of a but 

 terfly at night to an ordinary light. This is the instance men 

 tioned by Miss Murtfeldt, in Psyche* Volume IV, page 206, in 

 which she states that after 10 o'clock on the evening of August 

 20, 1882, a perfect specimen of Apatura lycaon flew in at the 

 window of her sitting room and was captured with a butterfly 

 net. Another example of the same species was taken earlier in 

 the evening, but after the lamps were lighted. Exceptionally 

 bright lights have, however, more often been known to attract 

 butterflies. Mr. S. H. Scudder, in Psyche, Volume I, page 28, 

 records the occurrence of Grapta j-album in numbers at the 

 lantern of the flash-light on the island of Nantucket. At the 

 meeting of the Brooklyn Entomological Society of October 6, 

 1885, Mr. Henry Edwards stated that he had been informed by 

 Dr. C. Hart Merriam that the light-house keeper on Lake Ontario 

 had been greatly annoyed by the large swarms of Anosia plex- 

 ip pus which flew against the light and obscured it {Entomologica 

 Americana, Volume I, page 160). At the same meeting Mr. 

 Edwards called attention to the fact that the electric light, since 

 its introduction, had been observed to attract butterflies occasion 

 ally. He had observed Papilio troilus, Vanessa atalanta, V. 

 cardui, V. hunter a, V. antiopa, Anosia plexippus, and Cya- 

 niris pseudargiolus. The principal object of this compilation 

 of instances is the recording of the fact that at midnight, May 

 2526, 1898, a fresh specimen of Pholisora catullus was caught 

 by me flying about the gas jet in my house in West Washington, 

 D. C. Speaking of the instance the next day to Dr. W. J. Hol 

 land, he informed me that while Satyridas and Hesperidiidas in 

 the tropics fly in dark woods, and are occasionally seen at twi 

 light, such instances as that recorded above are very rare. Of 

 our North American species he considers Eudamus tityrus to 

 be the latest flyer. Nearly all of our northeastern butterflies, as 

 pointed out by Scudder, however, are found abroad before 7 or 8 

 in the morning of a summer's day, and long before nightfall, 

 with closed wings and antennae snugly packed between, they are 

 quietly resting beneath some leaf or clinging to some grass blade. 

 The observation on P. catullus is entirely new, and is to be ex 

 plained like the previous one on E. tityrus and Miss Murtfeldt's 

 observation as well, by the fact that the butterflies had gone to 

 sleep near the window and were rudely disturbed by some noc 

 turnal bird or animal. 



The subject was discussed by Messrs. Ashmead, Marlatt, 

 Johnson, and Pratt, all of whom had collected extensively at
