just behind the mouth  
fg The pupae measures about 0.30 111. in length and 0.22 inch    
  in width across the bases of the wing cases, this being the widest  
  part of the body. The color is yellow, the surface apparently   V·_. 1
  smooth, but under a magnifier is seen to be clothed with 1Hl11lltC  
  erect setae, some brown, others brown-tipped. A noticeable series  
  of these little spines follows the margin of tl1e prothorax.  
g The pupae may be observed, a dozen or more attached to a  
  leaf, about the first of July. Some have been secured June    
  Adult beetles come from them during the early part of July and    
  continue to come forth for a couple of weeks. When fully ma-  
  ture the adults 1nay place eggs for a. second ge11eratio11 which  
  becomes adult in late August and in September. Beetles of the  
. T second, and some of the first brood, find hiding places in October  
  and November among rubbish and, grasses, where they remain  
  over winter. In the spring there are thus beetles of various ages ’  
·   that lay eggs and start the first brood of the season.  
  The egg stage lasts about a week. The larva or grub stage,  
  during which most of the injury is do11e, may last about 15 days. 3  
A The pupae stage lasts about a week. The whole life period from  
_l egg to adult thus covers about o11e month. Adults may live for  
1 eight months or more if they hibernate, but those maturing early    
, in the season probably soon die after they have eompleted the {lg 
, placing of their eggs on the plants.  
A FOOD PLANTS OF THE MEXICAN BEAN BEETLE y 
Wliile the insect is partial to garden beans, such as snap  
A beans and pole beans, it will attack other members of the bean  
  family, such as lima beans, and at times eowpeas and even soy-  
  beans, tho the writer has 11ot observed any very serious harm  
done to the two latter. Some other leguminous plants, such as  
y Florida beggar weed, alfalfa and even sweet clover, have been  
-   said to suffer injury on some occasions. A few non-leguminous  
‘ l plants have been observed to furnish the beetles a little food at  
1 times, but probably will never be in any serious danger froni the 5  
  insect, for it is known that many injurious species gnaw plants V.
