two names, 257. Thought, by some, to be distinct species, 257. 

 First noticed in Khode Island in 1860, 257. Later observations of it, 

 257. Its rapid spread and distribution, 258. Not yet known in 

 Canada, 258. Is mainly distributed through infested beans, 258. 

 Precautions that would limit its spread, 258. Its occurrence in 

 imported beans at the Centennial Exposition, 259. Maybe identical 

 with the South African bean-seed weevil, 259. Its occurrence in 

 Europe, Asia, Africa, and South America, according to Fauvel, 260. 

 General features of the beetle and illustration of it and its early 

 stages, 260. Compared with the pea-weevil, 261. Say's description 

 of the beetle quoted, 261. Eiley's description ot fabce referred to, 

 with his comparison of it with obsoletus, 261. Ticketed in collections 

 as ^./a6ce Fabr., 261. Explanation of this name, in MS. notes and 

 a publication found of Dr. Fitch, 262. The MS. in possession of 

 the Boston Society of Natural History, 262. A copy of the same 

 furnished for present publication, 262. B.fabce described by Dr. 

 Fitch and published in 1861, in the Transactions of a Rhode Island 

 Society, and in separate slips, 262. Dr. Fitch's description of the 

 bean-weevil, 262-3. B. fahce Fh. had been changed inadvertently to 

 B. fabce Fb. 264. Severe injuries, and rapid multiplication of the 

 bean-weevil, 264. Its destructiveness as reported by Prof. Popenoe, 

 265. Instance of its multiplication, 265. Infested beans should not 

 be planted, 265. Not sufficient to destroy the inclosed beetles, 

 265. Prof. Goff's experiments on impaired germination of weevil- 

 eaten seed, 266. The same by Professor Beal, 266. The same by 

 Professor Popenoe, 266. These experiments contradict former 

 belief, and show that the germ is destroyed or much injured, 266. 

 This is at variance with the old European authorities, quoted, 267. 

 Experiments, in Europe, in testing vitality and productiveness of 

 weevil-eaten seed, 267. With germination hardly impaired, pro- 

 ductiveness is seriously injured, 268. Infested beans unfit 

 for food, 268. Epitome of life-history of the bean-weevil, 269. 

 A brood of dwarfed bean-weevils from Waterbury, Conn., 269. 

 Why they were dwarfed, 270. They suggested successive broods in 

 the same beans, 270. Mr. Schwarz on consecutive generations, 270. 

 Professor Popenoe on the question, 270. The fact of continued breed- 

 ing established, 271. Oviposition, 271. The larvae entering the 

 beans, 271. The third or fourth brood of the insect, 272. Oviposi- 

 tion on infested seed, 272. Transformation to the final stage, 272.
