Vol. II of this work treats of the Crustacea and insects. Unfor-

HARRIS, T. W. Insects Injurious to Vegetation. 

 (Flint edition.) Orange Judd Company, New York. 

 Price, plain plates, $4; colored plates, $6.50. 



Although this is an old work and consequently somewhat out of 

 date as regards classification, it is one of the best books on insects 

 ever written ; it doubtless has done more to stimulate an interest in 

 the study of insects than any other American work. It is magnifi- 

 cently illustrated.
