in the woods of Miunesota. They have beeu reported from 

 Finland, Scandinavia, Bohemia, Germany and Minnesota. 



Genus Pseudosira Schott, Borner 



This is a scaled genus similar to Entomobrya, one species is 

 found here, and has been described by Lubbock from England. 

 They seem to live in mucli dryer places than the other 

 Collembola.

Description : Length — 2.65 mm. Color — Steel blue with some 

 brown. Anteunfe — Slender, long; I shortest, II and III sub- 

 equal; IV not quite twice as long as III but little over twice as 

 long as I. Ocelli — Sixteen. Claws — Two, both slender,

 Furcula — Long and slender, dentes plus mucrones longer than

Variation: Those described by Collinge had no basal spine 

 while mine have. 



Habitat: Found under a rotten log in fairly dry sand in 

 Cucamonga Canyon. Nicolet in describing this species, says 

 that it is found in houses and is very rare. Collinge found it

Family PODURID^ 



This family is a large one and is less specialized and more 

 primitive than the Entomobrya. The antennae are short and 

 many of them have sense bulbs at the end. Ringed antennae 

 are entirely unknown. The claws show reduction. In some 

 genera the inferior claw is little more than a bristle, while in
