 species in an authoritatiA'e manner. The bulletin gives in detail the distrilm- 

 tion and life history records of several species and discusses their relationshij* 

 to the "curly-leaf" condition frequently found on sugar beets. Doctor Ball

 Nathan Banks, U. S. Dept. of Agric, Bulletin Bureau of Ento-

This is a valuable and thorough contribution to this little known grouji. 

 which is of recognized economic importance. Keys are given for the families, 

 genera and species, each species being fully described, five proving to be new. 

 There are ten full-page plates. Chapters are also given on structure, life- 

 history, geographical distribution, abundance, historical and classification, and 

 there is a synomical list of the North American ticks, together with a full 

 bibliography. Very little systematic work has been done on this group and 

 there is an excellent field for investigation. — Karl K. Coolidge.
