of Circ. 16; February 7, 1910; 4 figs.). — This insect was originally 

 an enemy of the sugar cane, but transferred its attention to corn in the 

 southern part of Carolina, where sugar and corn are grown over the 

 same territory. It is the larva of a smoky yellow moth which lays its. 

 eggs in the early evening on the upper side of the leaves. The larvae 

 hatch in from seven to ten days and commence to eat the growing tender 

 tip and upper leafy portion of the plant ; they then descend to the lower 

 part of the stalk and tunnel in the pith. This weakens the plant so 

 that a high wind late in the season before the corn is matured breaks 

 off the plants at the surface of the ground. 



There are two generations a year, the first one pupates in the stalk 

 and the second in the root. 



Eotation of crops is the best general preventive of injury from 

 insects affecting field crops, and the thorough early destruction of stalks 

 and stubble remaining on the field is recommended. — V. G. J.

Cotton Bolls, Plant-Bug's Injurious to. By A. W. Morrill, 

 Ph. D. {U.S.A. Dep. Agr. Bur. Entom., Bull. 86; June 14, 1910; 

 5 plates, 25 figs., 31 tables). — This bulletin deals principally with the 

 conchucla {Pentatoma ligata Say.), but gives descriptions of other insects 

 detrimental to the cotton boll, among which are : The grain bug (P. sayi 

 Stal.), the brown cotton bug {Euschistus servus Say), the green soldier 

 bug {Neyara liilaris Say.), and the leaf-footed plant bugs {Leptoglossus 

 phyllopus L., L. oppositus Say., and L. zonatus Dall.). These pests, in 

 addition to destroying many cotton bolls and thus adding to the injury 

 done by the cotton boll weevil, cause more or less staining of the fibre, 

 which reduces the quality and value. — V. G. J. 



Cotton in Leeward Islands, Manurial Experiments with. 



By H. A. Tempany {V/est Indian Bull. vol. x. 3, p. 269, 1910).— 

 A record of continued experiments with the results obtained. In St. 

 Kitts the application of manure, on the whole, show^ed no marked 

 difference in the yield of cotton, the no-manure plot giving a higher 

 average per acre (during five years) than those manured. 



In Monserrat the largest return (all were high) was given by plot 9 

 in which sulphate of anniionia (20 lb. of nitrogen) resulted in an in- 

 crease of 312 lb. of seed cotton.
