" The P. Marcellus is still more common in the same northern localities, and feeds 

 upon the same shrub. It is also well figured in the work to which I have referred. 

 The pupa-case is occasionally of a pea-green colour, and remains unchanged during 

 the winter. In their perfect state these two species are readily recognized by their 

 peculiar modes of flight, as well as difference in size and markings. 



" P. Asterias in the larva state feeds on all species of Umbelliferae, not excepting 

 Cicuta virosa, the most virulent of our vegetable poisons. 



" P. Philenor, in the same state, eonfines itself to the several species of Aristolo- 

 chia ; A. Serpentaria, in this vicinity, constituting its principal food. It is badly co- 

 loured in Say's ' American Entomology ; ' in Boisduval it is better, but far short of the 

 original while living. 



" You will perhaps be surprised to learn thut P. Cresphorites, Herbst., described 

 and figured as P. Thoas in Leconte's Boisduval, has found its way as far north as my 

 locality. In the August of last year I captured four beautiful specimens in my lawn. 

 The present season two have already been seen here, and I have received one from the 

 Scioto valley near Columbus. At the south it feeds on the orange trees ; what its food 

 is here I have not yet discovered. I do not think it has visited this section of the 

 country till very recently. 



" Among the most rare species which I have taken, are Vanessa Milberti, Melitaea 

 Phaeton, Xanthidia Nicippe, and Limenitis Arthemis. 



" It may interest you to learn the fact that three species of your English butterflies 

 have become naturalized in this vicinity ; viz., Vanessa Antiopa, V. Atalanta, and 

 Lycaena Phlaeas. All are now abundant. It is perhaps doubtful whether the last is 

 specifically identical.'' 



The President announced that Herr Herrich-Schaeffer, having come into posses- 

 sion of the works of Hubner and Panzer, would dispose of copies, including the con- 

 tinuations, at greatly reduced prices ; and that he would receive in exchange English 

 entomological books and English and Foreign Lepidoptera. Also that he had for sale 

 or exchange small collections of European Lepidoptera. He intended to terminate, 

 during the ensuing winter, his works on the Lepidoptera of Europe ; and for illustra- 

 tion therein, he begged the loan of new species, especially of extraordinary genera of 

 Nocturnes ; and promised to return them in good condition as soon as possible, and 

 free of expense.
