Papilionidse, Daiiaidte, Pieridse about one-fifth of the described 

 species. 



The collection of the American Coleoptera has been separately 

 arranged, according to Dr. J. Le Conte's catalogue, by Mr. 

 Benjamin P. Mann, during the past year. The work is finished 

 so far as Dr. Le Conte's catalogue goes. Thirty-six boxes are 

 already arranged. The remainder of the collection is provision- 

 ally divided in families and genera. This collection now contains 

 only a small part of the known species. But further work in 

 the general collection, and in those of Melsheimer and Ziegler, 

 will add a considerable number of the rarer species belonging 

 to the western part of the United States. The Carabidae have 

 been carefully studied and determined by Mr. Sprague ; also a 

 part of the Lamellicornia. There are in the Museum nearly 

 one-half of the species of North American Carabid^ given in 

 Dr. Le Conte's catalogue (417 species to 1,107 by Le Conte). 

 The arrangement of the general collection of Coleoptera is 

 completed for the Cincindelidae and Carabidae, filling thirty-six 

 boxes. The same is true for the greater part of the Lamelli- 

 cornia. The account of the Carabidae shows that the collection 

 contains one-tenth of the described species enumerated in the 

 catalogue of Harold and Gemminger. The remainder are 

 separated by families in the new boxes. The other orders are 

 only separated by families in the new boxes, with the exception 

 of a small portion of the Orthoptera, which are further separated 

 and arranged. 



The whole collection fills nearly eight hundred boxes. The 

 whole work done as yet is very small, considering what remains 

 to be done, and the scientific revision and determination of the 

 species is of course only possible at present for a small portion. 

 Mr. B. P. Mann has carefully identified the North American 

 Catocalidae, and stated the collection to be rich in species. 



After careful consideration and by the advice of Dr. J. Le 

 Conte, it has been resolved that the collection of Coleoptera of 

 Melsheimer and Ziegler should no longer be kept separate, but 

 should be incorporated in the above-named collection. The 

 boxes containing them, far from being well made, have already 

 endangered the collection. Under the circumstances its incor- 

 poration in the general collection seemed important ; but every 

 insect is labelled with " Melsh." or " Ziegl.," and with another
