DYSPHAGA Lee. 



D. tenuipes Hald. Westville, two specimens (W); bred from red-bud (Ch), 

 and recorded also from hickory and walnut. 



Family CHRYSOMELIDiE. 



These are the " leaf beetles " which have the same tarsal structure as in the 

 Cerambycidce , but have the antennae much shorter, rarely as long as the body, 

 the joints comparatively stouter and larger toward the tip. The species are 

 rarely cylindrical, the thorax usually with a lateral margin or a distinct suture. 



The larvae are "slugs" or "grubs," usually also leaf-feeders, stout and 

 chunky like the larva of the potato beetle ; but some of them are leaf or root 

 miners, and these are long and slender. In this family there are a considerable 

 number of injurious species in both adult and larval stages, and as a general 

 rule the arsenites are available against them. Yet there are so many modifica- 

 tions that no universally applicable suggestions can be made.
