REPORT OF NATIONAL MUSEUM, 1908. 45 
some of the latter, together with a few specimens of other orders, 
being transferred to the permanent drawers recently furnished. 
The exhibition of insects in the west range of the Smithsonian 
building was practically completed as far as the available space 
permitted. During the year the old exhibits of termites and their 
work and of the Rocky Mountain locust were renovated and replaced 
in the series, new specimens being added to the former and new labels 
prepared. An illustration of the work of hymenopterous insects was 
also begun. A display of local insects, consisting of about 1,000 
species “of Coleoptera, Orthoptera, and Odonata, contained in 7 unit 
boxes, forms the beginning of a series intended to cover ail orders. 
Many butterflies and other insects have been collected for this series 
and will be installed later. Two additional unit boxes contain dragon 
flies from Japan and beetles from Africa. A series of especially 
injurious insects was projected, but only the boll weevil and the gipsy 
moth, together with some 30 species of mosquitoes, including those 
causing yellow fever and malaria, were placed on exhibition. Con- 
siderable work was done on the series representing mimicry, ete. 
Dr. L. O. Howard, Dr. H’ G. Dyar, and Mr. Frederick Knab con- 
tinued work on a monograph of the mosquitoes of North and Central 
America and the West Indies, which was the principal investigation 
of the year. About 8,700 insects were lent to entomologists in the 
United States and Europe for study and identification. The entire 
collection of bumblebees and Psithyridee was placed in the hands of 
Mr. H. J. Franklin, of Amherst College, for monographing. Speci- 
mens of beetles of the subfamily Aleocharine to the number of about 
9,500 were sent to Dr. A. Fenyes, of Pasadena, California, who has 
offered to identify the named species and determine the others ge- 
nerically, and later he will probably describe the new forms. Prof. 
H. C. Fall, also of Pasadena, received several hundred beetles of the 
genus Diplotavis of which he is preparing a memoir; and Mr. G. C, 
Champion, of London, England, a large number of North and Central 
American weevils of the family Barididee, for examination in connec- 
tion with his work on the Biologia Centrali-Americana. About 2,000 
specimens of Tineid moths were taken to England by Mr. August 
Busck, for comparison with collections in that country. 
Mollusks—Besides the material elsewhere referred to, there were 
acquired by exchange about 330 species of Philippine land shells 
from the Mollendorff and Quadras collections. Of the 1,500 species 
known from these islands, the Museum has now authentically-named 
specimens of about 1,330 species. Some 280 species of land shells 
from Madeira, the Canaries, and other Atlantic islands, including 
cotypes of species described by Lowe and Wollaston, and type speci- 
mens of 20 Mexican and Central and South American species de- 
scribed by Preston, were obtained by purchase. Mr. Charles Hedley
