The insect collection is estimated to consist of perhaps 100,000 

 specimens at the present time. Most of these are pinned, though 

 some alcoholic material is also available, particularly in certain groups. 

 Many of the smaller insects are mounted on slides for microscopic 

 study, and of these there are several thousand. 



The main pinned collection is arranged systematically in museum 

 trays, and here, as far as possible, the entire life history of each insect 

 is represented, this being particularly the case with the Lepidoptera. 

 Duplicate material, also systematically arranged, is stored partly in 

 museum trays, partly in Schmitt boxes. 



Between 800 and 900 types of various grades are also in the col- 

 lection, kept separate from the rest of the material, and stored in a 

 Brock metal cabinet. A list of these types is given elsewhere in this 

 pamphlet. 



Naturally the collection is most complete in those forms which 

 occur in the eastern United States. Other parts of the country are 

 represented to a considerable extent, however, particularly in the case 

 of insects which are of economic importance. Considerable material 

 from Central and South America and the West Indies is also present, 

 together with a small amount from the Old World, much of this exotic 

 material having been received through the kindness of graduates of 

 the college. 



The collection is kept in a large room on the second floor of the 

 building, directly connecting with both the senior and graduate ento- 

 mological laboratories, and is thus easily accessible for study.
