rogationis, G. comma, G. progne, V. antiopa, P. atalanta, P.

 thoe, L. pseudargiolus, L. comyntas, P. rap& and C. philodice, 

 were, perhaps, little, if any, affected. On the contrary many 

 others certainly were. In the beginning of its appearance at 

 the end of June, A. cybelc, while not rare, was considerably 

 less abundant ; a few specimens were seen up to as late as 

 September 6th. A. aphrodite was decidedly scarcer, while not 

 one specimen was seen of A. myrina, a species ordinarily ap- 

 pearing in moderate numbers. A few examples of P. cardui, 

 which is not common, were found, and two or three specimens 

 of L. ursula, also uncommon here, were reported. T. cd- 

 ivardsii, T. calanus, T. titus and C. hypophleas were scarce in 

 comparison with other years. The Papilios: polyxencs, troilus, 

 turnus and cresphontes were also in fewer numbers. The larvae 

 of the last named species were fairly common on prickly ash in 

 September and October, but were not so abundant as in some 

 years. The Hesperidae especially were scarce, and whereas in 

 other seasons many appeared, few' were to be seen of such com- 

 mon kinds as P. cernes, P. peckius, P. hobomok, etc., and even 

 the numbers of the little .4. numitor were somewhat restricted. 

 The only members of this family at all common were some of 

 the Nisoniadcs early in the season E. pyladcs and E. tityrus. 

 None of the rarities here, A. idalia, M. harrisii, P. nyctcis, G. 

 j-albnm, I 7 , milberti or P. philenor, appeared at all. The ob- 

 servations made above are for Detroit. In Oakland County, 

 25 or 30 miles northwest of Detroit, two or three specimens 

 each of A. myrina and P. nyctcis were reported. L. nrsula is 

 also more common there, and I saw six four in July and two 

 on September i4th. 



If, however, the usual numbers failed to appear there was 

 some compensation in finding five species whose presence was 

 previously unknown to me, although I have been more or less 

 familiar with the butterflies in this vicinity for fifteen years. 

 The first surprise was on May i2th, when three specimens of 

 Thecla iriis var. arsace were taken. They were flying at the 

 edge of an oak woods bordering a road and alighted on some low 

 vegetation where they were easily caught. A return to the
