Coffee Bean Weevil, New Breeding- Records of the. By 



E. S. Tucker {U.S.A. Dep. Agr., Bur. Entom,., Bull. 64, pfc. viL, 

 August 5, 1909; 1 plate, 1 fig.). — The author, while making field 

 observa'tions on the cotton boll- weevil in 1908, had his attention 

 directed to strange weevils occurring in dried cornstalks. 



Larvae, pupae, and a few adult insects were found which were 

 identified as the coffee bean weevil, Araecerus fasciculatus De Geer. 

 This species must therefore be recorded as a new enemy of cornfields, 

 selecting, as it does, cornstalks for breeding purposes. 



Previous published records of this insect show it to be common in 

 warm climates, and that it has no particular food preferences. It is 

 as likely to be found breeding in beans or any stored dry vegetable 

 products, including dried fruits, as, in dry pithy stalks, and is com- 

 monly found breeding as a scavenger in dry decayed cotton bolls.

Copaifera Species, A New, from Spanish Guinea, and on the 

 Mother-plant of Cameroon-copal. By H. Harms {Not. Konig. 

 Bot. Berlin, No. 47, vol. v. Nov. 1910, pp, 175-183; 1 text-figure).— 

 Pr. P. Preuss (in 1898) collected branches of a Oopal tree which, he 

 stated, was common in the forests along the river Sannaga. This tree is 

 said to yield " rubber- stone. " A nearer determination of the tree was, 

 however, impossible, as only leaves were borne on the branches. In 

 1909 Professor Buesgen brought back leaves and fruits of the tree, 

 and from this material Harms was able to conclude that very probably 

 the Copal tree, which was abundant in the Cameroon district, belonged 

 to the same species as the plant previously described by him from 

 Lake Leopold 11. under the name Copaifera Demensei Harms. Quite 

 recently this conclusion was confirmed by the collection of flowering 

 material by Mr. Eric Conrad at Fishtown, in the Cameroon district. 

 Harms is therefore able to describe and figure the plant in detail in 

 the present paper. 



A new species of Copal tree was collected by Mr. G. Tessmann 

 in Spanish Guinea, and is here fully described by Harms. — R. B. 



Copper Injury to Fruit Trees {Pom. Frang. March 1910).— 

 Use copper sulphate no stronger than 3 kilos to 100 litres of water, and 

 '1 kilo of molasses to make it adhere; the addition of lime neutrahzes 

 the action of the copper, and is therefore omitted. — C. H. H. 



Corn-planting", A More Profitable Method of. By C. P. 



Hartley {U.S.A. Dep. Agr., Farmers' Bull. 480, May 1910; figs.).— 

 A method is described by which all the many disadvantages of planting 

 Indian corn too thickly may be avoided and the rows set so as to permit 

 every plant to get its due share of space and light, without any added 

 expense at seeding time and with a great additional yield at harvest.
