INDIGENOUS AND EXOTIC. 



Not only is our own and the Lepidopterous fauna of other countries constantly 

 receiving numerous additions, but innumerable species of already described 

 Lepidoptera, both native and exotic, have never been figured, and, as a conse- 

 quent result, are in very many cases unknown to the student. The object of 

 this work is to give accurate colored illustrations of new and hitherto unfigured 

 species, the preference being given to those of North America. 



It is being published in monthly parts, each part containing one colored 

 plate; I will put on each plate as many figures as possible, the upper and 

 under surfaces will be given, also both sexes and larva, with stages of transforma- 

 tion wherever possible; the figures will all be drawn and colored from nature 

 by myself; as complete technical description and history of species as possible 

 will always be given. 



Parts 1, 2 and 3 are already out and ready for delivery. Part 1 contains 

 figures of Plalysamia Gloverii, c? 9, a magnificent new species from Arizona. 



Part 2 has Papilio Indra, ?, from Colorado, Pap. Anticostiensis, 9, new 

 species, from Anticosti Island near Labrador, Papilio Pilumnus, cf, New Mex- 

 ico, and Pieris Menapia, 9, Vancouver's Island, 8 figures. 



Part 3 is devoted to N. American Catocalid*, and contains 11 figures, 10 

 species, viz : fig. 1, Catocala Tristis, Edw , 2, 0. Viduata, Guen., 3, C. Lachry- 

 mosa, ^juen., 4, C. Obscura, New Species, 5, 6, C. Ilelicta, Walk., 7, C. Briseis, 

 Edw , 8, C. Faustina, New Species, 9, C. Cocciuata, Grote, 10, C. Cerogama, 

 Guen., 11, C. Serena, Edw. 



These are drawn and colored with such accuracy that a glance is sufficient to 

 iden'ify the species. 



My intention is to give one month Diuruals and the next Heteroceres, and 

 so on alternately; every third or fourth plate will be N. American Catocalidse 

 until the genus is exhausted. 



Only a limited number of copies are printed, (after which the drawings are 

 erased,) and will be furnished to subscribers only, at 50 cents per number, ex- 

 clusive of postage ; persons can remit the money as they receive the parts, or 

 pay a year's subscription in advance, as best may suit their convenience.
