Genus FOLSOMIA Willem 



FOLSOMIA FIMETAKIA (Linnaeus) Tullberg 



This well-known species of the soil fauna is already known to be 

 cosmopolitan in distribution. 



Specimens intercepted by the Federal Horticultural Board on 

 shipments from Guatemala agree with typical fvmetaria from 

 Europe except in one particular. The femur and tibiotarsus have 

 each an incomplete distal subsegment, the suture of which occurs 

 only on the lower side of the leg; that is, the side which bears the 

 unguiculus. 



Collected on Ckamaedorea species (pacaj'a or salad palm) from 

 Coban, Guatemala, at Inspection House, Washington, D. C, by 

 W. B. Wood and H. L. Sanford on January 29, 1920 (F. H. B. 

 No. 29456). 



Taken on roots of Ohamaedorea species from Coban, Guatemala, 

 at Inspection House, Washington, D. C, by H. L. Sanford, Febru- 

 ary 18, 1920 (F. H. B. No. 29598).
