ENTOMOLOGY. 485 



Beetle pests {Put. Dept. Agr. Jamaica, .' {1904), No. 10, pp. 217,218). — Notesare 

 given on injuries to rose trees and other plants caused by the attacks of Antichira 

 meridionalis and also on the depredations of Oncideres pustulata on beech. 



Bactericidal properties of the body fluids of worms, L. Jammes and H. Man- 

 doul (Compt. Rend. Acad. Sci. Paris, 139 {1904), No. 4, pp. 329-331).— In a study of 

 various species of Ascaris it was found that the fluids produced by these worms had 

 no effect upon pathogenic bacteria. The lesions produced by such bacteria were 

 formed as quickly and in as great extent after the bacteria had been subjected to the 

 action of the juices of Ascaris as before. The fluids produced by species of Taenia, 

 however, appear to contain a soluble bactericidal substance capable of influencing 

 the growth and virulence of pathogenic bacteria to a considerable extent. 



Notes on entomology, N. Hanks {Science, n. ser., 20 {1904), No. 500, pp. 155, 

 156). — Brief notes on recent entomological literature. 



Observations made on plantations in east and west Usambara, A. Zimmer- 

 mann {Per. Land-u. Forstw. Deutsch-Ostafrika, 1 {1903), No. 4, -pp. 351-381, pi. 1, figs. 

 2). — The author describes briefly the general conditions of plantations, especially 

 those devoted to coffee, with reference to the most important insect pests and fungus 

 diseases. Among the latter, especial mention is made of Hemileia vastatrix. 



A considerable number of injurious insects were observed attacking coffee, the 

 most important of which was the leaf miner Cemiostoma coffeellum. This insect is 

 described in its different stages, and an outline was presented of its life history and 

 its attacks upon coffee. Brief notes are also given on other insects and nematode 

 worms injurious to coffee. 



Cheimatobia brumata and means of combating it, G. Link (A'. Landt. Akad. 

 Handl. och Tidskr., 43 {1904), No. 3, pp. 253-272, figs. 8).— This insect causes con- 

 siderable damage to fruit trees almost every year. Notes are given on its habits and 

 life history and on the best means for combating it. It is recommended that fruit 

 trees be sprayed with Paris green at the rate of 50 gm. per 100 liters of water to which 

 150 gm. slaked lime are added. This mixture should be applied to the trees when the 

 leaf buds are first opening, again when the petals are falling, and a third time about 

 10 days later. Sticky bands and other obstacles placed on the trunk of the tree may 

 serve to prevent the females from laying their eggs. 



Notes on the migratory locust (Acridium peregrinum), W. Cartwright 

 {Jour. Khediv. Agr. Soc. and School Agr., 6 {1904), No. 3, pp. 81-89).— The life his- 

 tory of this insect in its various stages is briefly discussed. According to the author's 

 observations the period of incubation of eggs appeared to be about 21 days. It was 

 found that simple exposure of eggs to the sun for a period of one hour at a tempera- 

 ture of 88° F. was sufficient to kill them. This may be readily brought about by a 

 thorough plowing. The young nymphs may be successfully combated by the use of 

 a system of trenches and sticky obstacles. Brief notes are also given on birds which 

 feed upon this jjest. 



Lantana insects {Queensland Agr. Jour., 15 {1904), No. 3, pp. 655-657). — Lantana 

 has spread rapidly in many districts of Queensland and has proved a very noxious 

 weed. 



In Mexico a number of insects are known to attack the plant to such an extent as 

 to greatly prevent its spread. Some of these insects have been introduced into 

 Hawaii where lantana is also a serious pest. Ten species were introduced but failed 

 to establish themselves. They died either during shipment or subsequently as a 

 result of insect parasites or fungus diseases. Brief notes are given on the results of 

 the importation of other species which withstood the hardships of transportation. 

 These insects appear to be able to check lantana to some extent but not to destroy it. 



The aleurodids or mealy-winged flies of California with, reference to other 

 American species, Florence E. Bemis {Proc U. S. Nat. Mus.,27 {1904), pp. 471- 

 537, pis. 11). — This family of insects is found rather plentifully represented in parts
