REPORT OF THE ENTOMOLOGICAL DEPARTMENT. 
By H. A. Hacen. 
THE additions to the collection have been important, belonging 
mostly to the biology of insects. Prof. F. G. Schaupp, of Brook- 
lyn, N. Y., presented to the Museum his whole collection of the 
previous stages of U. S. Coleoptera, together with the types and 
dissections figured and published in the Bulletin of the Brooklyn 
Entomological Society. Mr. 8. H. Scudder presented a large lot 
of the previous stages of the U. 8. Lepidoptera. Mr. J. A. Lint- 
ner, of Albany, N. Y., presented previous stages of U.S. Sphingide 
wanting in the collection. Prof. J. H. Comstock, of Ithaca, N. Y., 
presented a large lot of the types of the U. S. Coccide. A large 
lot of Cave Articulata from Prof. N. 8. Shaler’s Survey of Ken- 
tucky were sent to the Museum by Prof. A. S. Packard, Jr. Mr. 
S. Henshaw, Miss Cora A. Clark, Mr. Charles V. Riley, and Rev. A. 
K. Eaton, of England, presented valuable specimens. A full set 
of all stages of Cosmosoma omphale, prepared by Mr. Witfield, 
Florida, who is the first American to prepare biological specimens 
of American Lepidoptera for sale, was given by the Assistant. 
The Library has been enlarged by some rare and costly works 
on Lepidoptera, by some rare older books, and by a large number 
of pamphlets and periodicals, by the Assistant. 
The collection has been remarkably free from pests. 
The numerous additions to the biological collection during the 
last years made a new arrangement unavoidable. Till now, 108 
boxes are finished, —the Lepidoptera to the end of the Bombycide, 
and the Coleoptera to the end of Hydrophilide. Both proved to 
be three times larger than before. The work had to be postponed 
for the want of cabinets. 
A large amount of spreading and setting insects was done by 
the lady assistant.
