Scientific Notes 



During the summer of 1908, various species of leaf Iioppers were abundant 

 in apple and maple plantations in nurseries. Typhlocyha rosae L., Empoasca 

 unicolor G., and E. mall Le B. were common on apples, and T. rosae, T. 

 bifasciata G. & B. and E. mail were also collected on maples. It should be 

 recorded that E. mail was present in unusual numbers on beans, and espe- 

 cially on potatoes in all of the leading areas of production. On account of 

 the abundance of this insect, many potato growers were of the opinion that 

 this species was responsible for the early decline of the plants, which, how- 

 ever, was largely due to tip burn, which was widespread and very destruc- 

 tive. The above species were kindly identified by E. P. Van Duzee. 



Punctures in bark by Oecanthus niveus De Geer are common on neglected 

 apple trees about Geneva. The eggs are deposited singly and may be found 

 in the bark of the limbs and larger branches. The eggs of O. nigricornis 

 Walker are laid in linear series, and are usually abundant in raspberry canes. 



Polijdrosus impressifrons Gyll., an imported species and heretofore not 

 recognized in this country, has been collected in large numbers by Mr. W. J. 

 Schoene on willows, poplars, roses, apples and pears at Geneva and Lyons.

Diestrammena marmorata in Colorado. The curious Diestrammena marmo- 

 rata (Haan), an orthopterous insect native of Japan, has just been found in 

 abundance in a greenhouse at Boulder, Colorado. The insect was brought 

 to my notice by Miss Myrtle Fawcett, one of my students, who reports that 

 it is strongly suspected of being responsible for great damage to violets. 

 Some years ago, the same species was found in a greenhouse at Minneapo- 

 lis, and on this account was figured in Lugger's work on the Orthoptera 

 of Minnesota, p. 254. Other species of the genus are well figured by Rehn 

 in Proc. Acad. Nat. Sci. Phila., 1906, p. 288 and 291.

Locust control in South America. Clippings from Montevideo papers, 

 kindly placed at our disposal by Dr. Howard, notice a recent law in relation 

 to locust outbreaks. There is a central committee appointed by the exec- 

 utive. This committee is charged with the execution of the law and is em- 

 powered to appoint departmental, sectional and district committees. The 

 law makes it obligatory for proprietors and tenants of lands invaded by lo-
