A new parasite of Carag-ana, A. de Jaczewski {Ecv. My col., 22 {1900), No. 87, 

 pp. 79-82, pi. 1). — A description is given of Fleospora caraganx, n. sp., found para- 

 sitic on tlie leaves of Cava gana arborescens in Russia. A list of other fungi occurring 

 on the leaves, branches, and trunk of this tree is given. 



A new disease of Solomon's seal, A. de Jaczewski {Rrv. Miicol., 22 {1900), No. 

 87, pp. 78, 79). — The author describes Cylindrosporhun l-omdrowi, n. sp., as parasitic 

 on the leaves of Pohigonahnn humilis. 



A new species of Exobasidium, Boudier {Jiul. Soc. Mycol. France, 16 {1900), 

 No. ^, pp. 15-17, pi. 1). — A description is given of E.vobasidinm hrevieri, n. sp., para- 

 sitic; on Asplenium filLv-femina. It is closely related to E. graminicolum, a common 

 parasite on the leaves of various grasses. 



Parasitic algae and fung-i of Java, M. Raciborski {II and III, pp. 46 and 49; 

 aha. itiBot. CentbL, 84 {1900), No. 10, pp. 316-319).— Ahoni 110 species are described, 

 of which 88 are new species and 11 new genera. 



Notes on the temporary injury due to copper fungicides {Ztsclir. Pflanzen- 

 krank., 10 {1900), No. 5, pp. 311, 312). — The leaves of a number of varieties of apple 

 trees are said to have been temporarily injured liy spraying with Bordeaux mixture.

ENTOMOLOGY. 



Report of the entomologist, II. A. Gossard {Florida Sta. Rpt. 

 1890 and 1900, pp. 53-76, pi. i, figs. 5).— The West India peach scale 

 {Dlaspds amygdal!) is reported as having been unusually injurious 

 during- the past season. A brief account is given of its distribution 

 according to the present knowledge of the subject, and the use of 

 mechanical mixtures of kerosene and water are recommended in com- 

 bating it. 



The San Jose scale has been found in 13 counties of the State. This 

 insect was attacked b}' a fungus disease, SphcBrostilhe coccophila. 

 This fungus has been sent to other States by special re(juest. During 

 the year experiments were made with crude oil and kerosene in com- 

 bating the San Jose scale upon peach, pear, and plum trees. On the 

 25th of January luidiluted crude petroleum was applied with an emul- 

 sion nozzle to pear trees which wore badly infested. All scales were 

 apparently killed, but a part of the trees subsequently died of fire 

 V)light, so that it was impossible to determine what the effect of the 

 ])etroleum was upon the trees. A number of plum trees werespraj^ed 

 on the same da}" with undiluted petroleum. A greater number of the 

 sprayed trees died than of those in the check row and were more inju- 

 riously affected than trees in adjoining rows that were sprayed with a 

 30 per cent mechanical mixture of crude oil and water. FiXperiments 

 with undiluted crude oil on peach trees indicated that it is unsafe in 

 Florida to apply this remedy to peach trees. The author concludes 

 that great care should l)e exercis(>d in the use of undiluted crude oil, 

 and reconunends that it should preferably be diluted before using,
