JORDAN AVID KELLOGG'S ANIMAL LIFE
(N. Y., Appleton, 1900, SO) is an introduc- tion to zoology of the most rational kind, abundantly and excellently illustrated. It is the only text-book of zoology we have ever seen which was readable almost from cover to cover. Generous space is given to insects. The authors point out "that the whole
life of animals,. . . all the variety of animal form and habit is an expression of the fitness of animals to the varied circumstanccs and conditions of their living.. . [and that this adaptation has] come about inevitably and naturally, and that it can be readily studied and largely understood." The whole book
makes this clear.
STAKPOR~ UNIVERSITY'S COLLECTION
OF JAPANESE SCALE INSECTS.-Mr. S. I.
Kuwana, at.sistant in entomology in Stanford University, spent all of last summer in Japan collecting and studying in the field the scale insects of that country, this being the first attempt to make a systematic investigation of Japanese Coccidae. Mr. Kuwana visited and traveled over all of the larger islands of the Umpire, and by reason of his knowledge of the language and geography of Japan was able to do very effective work. He gave spe- cial attention to the San Jos6 scale, in an attempt to solve, or nt least to contribute to the solution of, the problem of the native habitat of this insect. This scale was found to be distributed over the whole empire, and in certain regions to he a serious pest. Mr. Kuwana is now engaged in working over his notes and material relating to the San Jos6 scale and finds much evidence to uphold the belief that the insect is native to Japan. He hopes to publish his notes about Christmas time. The collections made by Mr. Kuwana on this expedition, which are large, belong to the entomological laboratory of Stanford University. As far as the duplicate material will allow I shall be glad to make exchanges with students of the Coccidae, or to present specimens to them. Until the material is worked over, however, the collection will be kept intact.
