REPORT ON THE ENTOMOLOGICAL DEPARTMENT. 
By Dr. H. A. Hacen, 
THE collection of North American Coleoptera, from the late 
Dr. John L. Le Conte, of Philadelphia, Pa., — bequeathed to 
the Museum, — is the most prominent addition. The collection 
fills three cabinets, with two hundred and eight boxes, and 
thirty-three larger boxes besides, seven of them not yet deliv- 
ered. The collection represents the well-used tool of a hard 
and incessant worker. 
The collection is indeed very large and important, and has 
been carefully compared with the Doctor’s works by the Assist- 
ant through the whole month of August. Of the types thirteen 
are wanting: two Mexican species given by the Doctor to 
the Philadelphia Entomological Society ; two were lost on the 
journey to Europe; eight, recognized later as synonyms, are 
probably present, but without label; one, Myodites Zeschi, is 
not yet found. 
With this collection are now returned to the Museum the 
types of Melsheimer, Ziegler, and Say, selected by Dr. J. L. 
Le Conte from the collections of Melsheimer and Ziegler when 
they were purchased for the Museum. 
In the printed catalogue, every species and the number of 
specimens have been checked off by the Assistant as a provis- 
ional catalogue. The full number cannot be given before the 
whole collection is delivered. 
A collection of the early stages of Lepidoptera, two hundred 
and twenty species, all new to the Museum, was bought from 
Dr. Staudinger, Dresden, Saxony. A new arrangement of the 
biological collection of the Lepidoptera was made necessary by 
this addition. This part fills now seven cabinets, with one hun- 
dred and twenty-six boxes. The biological collection of Lepi- 
doptera is certainly the richest of this kind in existence.
