LEPIDOPTERA— BUTTERFLIES AND MOTHS 
The present collection of lepidoptera contains about 100,000 speci- 
mens, representing 10,000 species. 
One of the most important gifts to this section of the department, 
and one which extended over several years, is the collection of butter- 
flies presented by the Very Reverend Eugene Augustus Hoffman, D.D., 
LL.D. Dr. Hoffman's desu-e was to extend the Museum's collection Hoffman 
so as to include the more important species of the world. He began, 
in 1897, by purchasing ($508) a series of the butterflies found in 
America north of Mexico, containing 1,650 specimens, representing 
475 species. The next year he added 2,250 specimens collected in 
Mexico, Central and South America, and during the following four 
years purchased and presented various collections, containing over 
2,500 specimens from South America, Australia, and Asia. 
Dr. Hoffman also provided funds for Museum expeditions to the 
Black Mountains, North Carolina, in 1900, 1901, and 1902. The 
material thus obtained numbered fully 13,200 specimens of various 
insects, among which were many butterflies and moths. 
After the death of Dr. Hoffman in 1902, many additions were made 
as the result of expeditions by Curator Beutenmiiller, the expenses 
for which Dr. Hoffman had provided. 
Since 1902, Mr. Samuel V. Hoffman has generously continued the 
work begun by his father, the Very Reverend Eugene A. Hoffman, 
in his efforts to extend the butterfly collection. His contributions g^^^^j ^ 
include 364 African butterflies, 3,600 specimens of North American Hoffman 
and exotic lepidoptera, and a collection presented in 1908 of specimens 
from Mexico, Brazil, Japan, and Africa. 
The collection which had been gathered by Dr. S. Lowell Elliot 
was presented to the Museum by Mrs. EUiot in 1890. It contained Eiuot 
6,600 butterflies and moths in absolutely perfect condition, almost collection, 
all of which were bred specimens, with many of the rarer types repre-
