many crops. The small beetles 

 attacking cucumbers (see 

 page 272, Part II), and 

 the one that works on aspa- 

 ragus are Chrysomelids. So 

 is the Elm Leaf-beetle. One 

 species works in the spring on 

 apple foliage and later in the 

 season on locust. Its larvae 

 mine in the leaves of the locust 

 and the insect is called the 

 Locust Leaf-beetle. It is brown 

 with a black band down the 

 middle of the back and is 

 flatter than most of the leaf 

 beetles, and somewhat wedge- 

 shaped. 



Bruchidce include a few 

 small species with tarsi like 

 the Cerambycidce and with 

 stout bodies and shortened 

 wing-covers. Their larvae 

 feed within the seeds of peas, 

 beans and other legumes. 

 They will be recognized usu-
