imported into this country several times, but so far 

 as known, none has become entirely acclimated. The 

 same authority says he believes it quite probable 

 their introduction will be effected sooner or later, in 

 spite of the reported failures of such individuals as 

 have been brought here to survive and procreate. 

 The most important of the foreign weevils is what 

 is familiarly known as the European bean weevil 

 (Bruchus rufimanus). It is common and destructive 

 in Europe and North Africa and although it prospers 

 on peas as well as beans, it seems to favor the Broad or 

 Windsor varieties. Chittenden reports that it was 

 found in nearly every one of many samples of Wind- 

 sor beans exhibited at the Columbia exhibition in 

 1893. During the same year the species was found 

 in peas at the college station, Texas. Apply the 

 same remedy as for weevil. 



Mexican bean weevil (Spermophagus pectoralis) 

 which breeds in the seeds of beans and cowpeas, is 

 another foreign weevil found in large numbers in 

 South and Central America. It occurred in great 

 numbers at the Columbia exhibition but the infested 

 material was fumigated or destroyed under Profes- 

 sor Chittenden's direction and thus its possible in- 

 troduction from that source was prevented. The 

 same treatment as for the common bean weevil is 

 recommended. 



Blister beetles. Chittenden, in his very compre- 

 hensive description of insects injurious to beans, 

 says that several of the many species of Meloidae, 

 or Blister beetles, so destructive to crops particu- 

 larly in the Southwest, are very injurious to beans, 

 peas and other leguminous crops. These insects are
