Light Traps, Lepidoptera at. By W. B. Turner [Jour. Agr. Res. xviii. 
pp. 475-481, Feb. 1920 ; i fig.). — A further contribution to the author's previous 
work in xiv. pp. 135-149. A description is here given of the trap. Collections 
were made on twenty-eight nights between May 14 and September 13, 1918, 
when 3,152 moths were caught, embracing over sixty species, of which 2,200 
or 69*8 per cent, were males, and 952 or 30-2 per cent, were females. , 
Five tables are given enumerating the results, together with meteorological 
data.— G. F. W. 
Lilium Farreri Turrill {Bot. Mag. t. 8847 ; June 1920). — A beautiful species 
allied to L. Duchartrei, hardy, and distinguished by its linear lanceolate cauline 
leaves dispersed throughout most of the stem, and relatively small Martagon- 
like flowers, the white segments of which are spotted with dark -purple spots. 
Seed collected by Mr. Farrer in Kansu. — F. J. C. 
Liming SoiL By E. C. Shorey {U.S.A. Dep. Agr., Farm. Bull. 921 ; 29 pp., 
5 figs.). — It is well known that liming improves the physical condition of heavy 
soils, neutralizes acidity and facilitates the decomposition of organic matter. 
The lime can be applied in the form of quicklime, slaked lime, or as finely powdered 
chalk or limestone. Where the soil is light and deficient in humus, liming must 
only be carried on in conjunction with green -manuring. — S. E. W. 
Liparis macrantha Rolfe {Bot. Mag. t. 8797, June 1919). — A native of Formosa, 
introduced by Mr. H. J. Elwes and flowered at Colesborne, this species produces 
a long spike of brownish-purple flowers with segments i- to | inch in length 
and very large for the genus. It thrives in conditions suiting Indian Calanthes.

Logan Blaclsberry. By G. M. Darrow {U.S. Dep. Agr., Farmers' Bull. 998, 
pp. 1-24 ; II figs.). — The Loganberry is a variety of Blackberry, not a hj^brid. 
It requires a deep, well-drained soil rich in humus. The young plants produced 
from the rooted, tips of the old canes require more care than ordinary seedlings 
or cuttings. They are planted 8 feet apart in rows 8 feet distant, and the canes 
are trained on a wire trellis. After fruiting, the old canes are cut down to the 
ground. Weak canes are also removed. The berries may be canned, dried, or 
made into jam. There is also a growing demand for the bottled juice, wiiich 
forms a pleasant beverage when diluted with three times its bulk of water. The 
Laxtonberry and the Mahdi are hybrids of the Logan and the Raspberry. 
5. E. W. 
Lonicera chaetocarpa Rehder. By W. B. Turrill {Bot. Mag. t. 8804 ; June 
1919). — Related to L. hispida, of which it was regarded as a variety. It was 
introduced by Mr. Wilson from W. China, is hardy, and forms a neat rounded 
bush. It is one of the best of the shrubby honeysuckles, and bears primrose- 
yellow flowers somewhat like those of a Diervilla in June. — F. J. C. 
Lonicera similis var. Delavayi Rehder. By W. B. Turrill {Bot. Mag. t. 8800, 
June 1919). — Originally described by Franchet as L. Delavayi, this native of 
S.W. China was introduced by MM. de Vilmorin. Its long-tubed yellow flowers 
are produced in late August, and, as it is a perfectly hardy evergreen climber at 
Kew, it should prove a useful addition to our gardens. — F. J. C. 
Ittaize, Insect Pests. By W. B. Gurney {Agr. Gaz. N.S.W. vol. xxix. 
pp. 641-650; XXX. pp. 196-202 ; 15 figs., I col. plate). — The most destructive of 
the insect pests of maize are described, with illustrations, viz. the Grain Weevil 
{Calandra oryzae), Angouraois Grain Moth {Ditrotroga cerealella), Yellow Maize 
Moth {Conogethes punctiferalis), and Com Earworm {Chloridea ohsoleta) . The Pink 
Comworm {Batrachedra rileyi) attacks the ears of the maize in the field and in 
store. It is not possible to control this pest in the growing crop, but it can be 
effectually dealt with by fumigating the harvested cobs with carbon di-sulphide. 
The inconspicuous moth is grey. The pink caterpillar is | of an inch long. 
The Army Worm {Cirphis unipuncta) attams a length of inches. It is 
dark brown or black in colour. The moth is rarely seen, as it flies at night. It 
has a light spot on the fore wing ; the prevailing colour is buff. Winter cultiva- 
tion of the soil exposes the pupae to birds and to frost. If in early spring the 
young caterpillars are discovered in the weeds and grass near the maize fields, 
the infested patches must be cut down and burnt. When the Army Worms 
move in mass in a definite direction they may be trapped by ploughing a steep 
furrow in the line of their advance. They can then be crushed or sprayed 
with oil emulsion. If the caterpillars infest the crops, they may be destroyed by
