i6 COLLEMBOLA OF MINNESOTA 



Of the American Collembola known hitherto, a few were 

 reported by Fabricius (1780) in his Fauna Groenlandica, some 

 by Say (1841) from New York State, also from the same part 

 by Fitch (1846). Packard described mostly from Essex Coun- 

 ty, Mass., though some of his came from Maine, and others from 

 Tennessee and Texas. A. D. MacGillivray, in the Canadian 

 Entomologist, 1891-1896, gives not only several new species, but 

 some very helpful keys. His list of the American species of 

 Collembola, and his key to the American species of Isotoma are 

 especially valuable. His specimens were from Massachusetts, 

 New York, Washington, D. C, Washington State, Tennessee, 

 Florida and New Mexico. Harvey and Folsom have published 

 several descriptions, based mostly on Maine specimens, in the En- 

 tomological News and in Psyche. Besides these in the English lan- 

 guage, Schaffer has described two collembolans from Southern 

 Georgia, and Schott has a very good paper on California Coll- 

 embola. These, with a few Chilian species of Nicolet, and a 

 single Venezuelan species by MacGillivray, comprise nearly the 

 whole American list. Thus, the east, the west and the south 

 have been all studied in varying degrees, but from the upper 

 Mississippi basin, few if any species have ever been reported. 

 Probably Dr. Folsom's collection is the only one in the country 

 that contains many specimens from the states of the middle 

 west. Our Collembola fauna would naturally be expected to 

 contain species which have never been described, nor, indeed, 

 found elsewhere ; and such proves to be the case. While not 

 nearly all the known American species have been found in Min- 

 nesota, so far ; yet, on the other hand, many species described 

 from Europe and never hitherto reported from the Western Hem- 

 isphere, are found to occur here in Minnesota. 



List of Publications Consulted. 



Arranged Alphabetically by Authors. 



Articles marked by a star are those that have been found especially 

 important and helpful. To some of these, especialb' to Schott, Schaffer 

 and MacGillivray, I am largely indebted for many of the keys as 

 well as other thingrs.
