Bulletin No. 12 of the same Division, also just issued, is entitled 

 Miscdlaneous Notes on the Work of the Divhioii 0/ Entomology for Season 

 of 1 885, prepared hy the Entomologist. It is a pamphlet of 46 pages and 

 I plate, and contains a Report on the productim and manufacture of 

 Buhach, by D. W. Coquillet, which is full and of much value; additions 

 to the 3rd Report on the causes of the destruction of the evergreen and 

 other forests in Northern New England, by A. S. Packard; The Period- 

 ical Cicada in Southwestern Indiana, by Amos K. Butler; and Notes of 

 the year, of various insects. 



Tht Fourth Report of the U.S. Entomological Commission, on the 

 Cotton Worm, bv Prof C. V. Riley, is a volume of 546 pages, carefully 

 indexed, and illustrated by 64 plates. Of these, 48 plates and 137 pages 

 are devoted to the mechanical devices for the destruction of the cotton 

 worm. The three chapters treating of the remedies and preventives em- 

 ployed in coping with the insect (70 pages), are especially valuable to 

 the agriculturist, as many of them would be equally available against 

 other insect attacks. 



The four large octavo voUhtk-s of the Entomological Commission, 

 and its seven Bulletins, of nearly 3000 pages in the aggregate, 150 plates, 

 several hundred of wood-cuts, and a number of map.s, may confidently 

 be appealed to in justification of the action of the (General Government, 

 if its wisdom be questioned, in authorizing and providing for the work 

 of the Commission now brought to a close in its final publication. 



Prof Riley, in his Presidential Address before the Entomological 

 Society of Washington, as published in the Proceedings of the Society, 

 has referred to some of the insect attacks which had recently come under 

 his observation. 



An Address upon Hortiultural Entofnologv (23 pages), by Prof F. 

 M. Webster, before the Indiana Horticultural Society, very clearly pre- 

 sents the importance of insect studies to the horticulturist, who may not 

 to any great e.Ntenl ward off insect attack by the means successfully re- 

 serted to by the agriculturist — by rotation of crops. It also gives com- 

 prehensive notice of several of the nuirc injurious insects with which the 

 horticulturist must contend. 



The same author has also issued a carefully prepared illustrated 

 paper, of 36 pages, on the Insects affecting the Corn Crop, extracted from 

 the Indiana Agricultural Report for 1S85. Of the fifty species of corn 

 insects noticed, several are accompanied with useful bibliographical lists. 



Insects Injurious to the Apple, is the title of a paper, by Prof. B. F. 

 Koons, extracted from the Report of the Connecticut Board of Agri- 

 culture, for 1885. The claims lor the study of entomology are well 

 presented in it.
