32 REPORT OF THE SECRETARY. 



7. Catalogue of the described lepidoptera of North. America, by 

 Dr. John G. Morris. This catalogue enumerates over 2,000 species 

 of butterflies, moths, &c, which occur in the United States proper. 

 "Yet there is reason to believe," says the author, "that hundreds still 

 remain to be discovered/' In the preparation of this catalogue, all 

 accessible books have been consulted, and it is believed that few descrip- 

 tions of American lepidoptera have been overlooked. The classifica- 

 tion adopted is that recommended in part by Herrich-Schaeffer and 

 Walker ; but in some of the families, Guenee has been followed. 



The following works are in preparation for publication in the Smith- 

 sonian miscellaneous collections: 



1. Elementary introduction to the study of conch ology, by P. P. 

 Carpenter, of Warrington, England. 



2. List of the species of shells collected by the United States ex- 

 ploring expedition, by the same author. 



3. Descriptive catalogue of the shells of the west coast of the United 

 States, Mexico, and Central America, by the same author. 



4. Bibliography of North American conchology, by W. G. Binney. 



5. Descriptive catalogue of the air-breathing shells of North Amer- 

 ica, by the same author. 



6. Catalogue of North American Crustacea, in the museum of the 

 Smithsonian Institution, by W. Stimpson, M. D. 



7. Catalogue of the described Neuroptera of North America, by 

 Dr. H. Hagen; edited by P. R. Uhler. 



8. Classification of the Coleoptera of North America, by Dr. John 

 L. Le Conte. 



9. Descriptive list of the diurnal lepidoptera of North America, by 

 Dr. J. G. Morris. 



10. Descriptive catalogue of the hymenoptera of North America, 

 by H. De Saussure. 



11. Descriptive catalogue of the diptera of North America, by Dr. 

 Dr. H. Loew and Baron Osten Sacken. 



12. Catalogue of North American orthoptera, hemiptera, and homop- 

 tera, by P. R. Uhler. " .. 



Most of these are nearly completed, and will be published during 

 the year 1861. 



The thanks of the Institution are due to the gentlemen whose names 

 have been mentioned in connection with the preparation of the several 

 works just mentioned, since their labors have been bestowed for the 

 advance of science, without any other reward than that which might 

 flow from the reputation justly due to the authors of such productions.
