304 THE ENTOMOLOGIST. 



to the pests of the mainland cotton-growing districts. The 

 presence of Dysdercus discolor, Walker (or as it is termed " an- 

 nulliger (sic !) Ubler), is very interesting, forming the fourth 

 known cotton pest in this genus, the others being suturdlus 

 from the mainland, andrece in company with discolor and cingu- 

 latus from the Orient. 



Cockerell (2) has summarized Mrs. Fernald's recent Catalogue 

 of the Coccidas. The same author (6) notes two grave errors in 

 geographical names. " Arrayo," a name universally used in the 

 south-west of North America for a dry watercourse, occupied by 

 water only after heavy storms, has come into use in recent en- 

 tomological literature as the name of a town, and finally meta- 

 morphosed into " Arrogo, New Mexico." "Baja" has become 

 the name of a supposed place in California, whereas it simply 

 means "lower," i.e. "Baja California" = Lower California, in 

 Mexico. 



The first attempt to manufacture beet-sugar in the United 

 States was made in 1830 (3), but there were only three factories 

 in operation sixty years later ; in 1902, however, there were 

 forty-two, and these are steadily increasing. Estimates made 

 in the U. S. Dep. of Agriculture place the world's production 

 of sugar in 1902 at nearly ten million tons, of which nearly 

 six millions were manufactured from sugar-beets. Some 150 

 species of insects are noted as using beets for food, and, while 

 comparatively innocuous so far, will probably become more 

 injurious each successive season. In a similar bulletin of the 

 U. S. Division of Entomology, various Diptera, especially species 

 of Isosoma, destructive to cereals, are fully dealt with (4). 



The Seventh Eeport of the Forest and Fish Commission of 

 New York contains an account of the insects affecting forest 

 trees, prepared in the sumptuous manner now expected from 

 that State (5). Species affecting the pine, to the number of 

 some forty, receive the most attention, and are considered 

 at more or less length, the Scolytidae in particular, with 

 their associated insects. The other trees discussed are the 

 balsam, spruce, arbor-vitte, and oaks. The account is illustrated 

 by three beautifully coloured plates of insects affecting hard- 

 pine, white pine, and oak, by five photographs of injured trees 

 or forests, and ten plain plates, principally representing Scolytid 

 work. 



With January, 1904, the ' Insect World ' commenced its 

 eighth volume (7) under a slightly altered title, ' The Insect 

 World : a Monthly Magazine devoted to the useful application 

 and scientific study of Entomology,' edited by Yasushi Nawa; 

 Director of Nawa Entomological Laboratory, Gifu, Japan; with 

 this, the insect accompanying the title is also changed, the 

 new-comer being the remarkable moth, Epijy/rops nawai, Dj^ar.
