pects of the Melbourne Exposition. He returned on the same steamer 

 with Mr. Koebele, joining the latter in New Zealand. 



Both gentlemen speak in the highest terms of the courtesies which 

 they received both at the hands of the Ex])osition Board and from 

 prominent men in Australia and New Zealand. Our esteemed corre- 

 spondent, Mr. Frazer S.Crawford, of Adelaide, was particularly kind and 

 placed every facility at their disposal. It goes without saying that 

 Messrs. Maskell and Wight received Mr. Koebele most cordially in New 

 Zealand. 



The Periodical Cicada in 1889.— Brood VIII, which is of the seventeen- 

 year race, will appear tbis year through quite an extent of country. 

 The region commences in southeastern Massachusetts, extends south 

 across Long Island and along the Atlantic coast of New Jersey, Dela- 

 ware, and Maryland as far as Chesapeake Bay ; then up the Susque- 

 hanna Eiver in Pennsylvania, to a point a little below Harrisburg; 

 thence westward in Ohio, embracing the southwestern corner of the 

 State and the northwestern portion of Kentucky, and then upward 

 through southwestern Indiana, ending in central Illinois. It is possible 

 also that there is an eastward extension of the region from Kentucky 

 into southern West Virginia, as Cicadas occurred in 1855 in the Ka- 

 nawha Valley, and also in the counties of Buncombe and McDowell, in 

 North Carolina ; but as these appearances were not verified in 1872, it 

 is probable that they belonged to Brood XVIII, which is of the thir- 

 teen-year race. 



We shall be glad to receive full accounts this year of all appearances 

 from any of our correspondents, and from all others who will be kind 

 enough to write us of occurrences in their vicinity. Accounts from 

 North Carolina and West Virginia are especially desired, as these will 

 tend to clear up any doubt remaining as to what brood occurred in those 

 States in 1855. 



Economic Entomology in California.— We have just received from Mr. 

 W. G. Klee a little work published under the auspices of the State Board 

 of Horticulture, and entitled "A treatise on the Insects Injurious to 

 Pruit and Fruit-trees of the State of California." Mr. Klee is a little 

 weak in his technical entomology, and frequent misspellings of scientific 

 names occur. He quotes freely from other writers, however, and his 

 scientific orthography is not a fault which will trouble his practical 

 readers. His illustrations are mainly borrowed, but most of those 

 which are original are fairly good. His colored plates, which are re- 

 printed from the Biennial Report of the State Board of Horticulture 

 for 1885-'86, are very happy in catching the cbaracteristic appearance 

 upon the twigs, leaves, and fruit of the three species of scale-insects so
