BEANS. 



Bean-seed Beetle. Bnichus rufimamis, Bohm. 

 Pea-seed Beetle. B. pisorum = pisi, Linn.

 Bean split open, showing cell ; 4 and 5, larvfe, natural size and magnified ; 6 and 

 7, pupa;, natural size and magnified ; 8, Bean injured by beetle, vegetating ; 9 and

 while to refer again to the subject but for the circumstance of three 

 other species of Bruchi (also infesting Pea and Bean seed) having been 

 found, together with our two long-established pests, during the past

 synonyms, and appropriate to the antenna of the male being red.— E. A. O.
