The Orthoptera of Indiana. — By W. S. Blatchley, State Geologist, 

 Indianapolis, Ind. From the 27th Annual Report of the Depart- 

 ment of Geology and Natural Resources of Indiana, 1902. One 

 Vol., 8vo., pp. 123 to 471. 

 No one better qualified than the author of this work could possibly 

 be found to prepare a handbook of the Orthoptera of Indiana, and admir- 

 ably he has performed his self-imposed task. For nearly twenty years he 

 has been a close observer and student of the insects of this order and has 

 published many papers of both a systematic and descriptive character 

 upon them. Several of these have appeared from time to time in the 

 pages of this magazine. The book contains the results of his investiga- 

 tions and studies, and is designed to impart a full and clear knowledge of 

 this important group of insects to school pupils and young people on the 

 farm. Certainly anyone desiring to study the order, whether living ii> 

 Indiana or Ontario, or any of the neighbouring States, will find his way 

 made easy by this work, and will learn without much difticulty how to 

 distinguish the species and what their life-histories and characteristics are. 

 The opening pages of the book give a full and clear account of the 

 external anatomy of a Locust, the natural enemies of the Orthoptera, and 

 a bibliography of the more important books and papers on the order. The 

 main portion of the volume is termed " A Descriptive Catalogue of the 

 Orthoptera Known to Occur in Indiana." Convenient keys are given to 

 the families, genera and species, facilitating the identification of a speci- 

 men, and these are followed in each case by scientific descriptions, the 

 synonymy, geographical distribution and other information ; in the case 

 of the Locusts especially the accounts of the habits of the species are very 

 full and interesting. The work is rendered complete by a chapter on 

 the Life-zones of the State as illustrated by the distribution of the 

 Orthoptera, a glossary of the terms used and a full index. There are over 

 120 excellent figures in the text, largely taken from Lugger's Orthoptera 

 of Minnesota, and a beautiful coloured plate of the remarkable pink 

 variety of the Oblong-winged Katydid (Amblycorypha oblongi/olia).
