REVIEWS. 



Third Report of the United States Entomological Commission. 

 Washington : 1883. 347 pp. Demy 8vo, with Appendices, 

 85 pp. ; one coloured and three plain maps and 64 plates. 



This very handsome production, on the part of Mr. C. V. 

 Riley and his colleagues, makes one feel how much ahead are 

 our American cousins in practical Entomology, and some shame 

 that our Government should not follow the enlightened example 

 of the American United States Department of Agriculture. 

 Much as some of our friends have done privately in the cause 

 of Economic Entomology in this country, it is too much to 

 expect of them to issue such works as these American reports, 

 when the enterprise, being for the public good, ought to be that 

 of the State. 



The Report now under consideration deals with " The Rocky 

 Mountain Locust, the Western Cricket, the Army Worm, Canker 

 Worms, and the Hessian Fly; together with descriptions of 

 larvae of injurious forest insects, studies of the embryological 

 development of the locust and of other insects, and on the 

 systematic position of the Orthoptera in relation to other orders 

 of insects." A large proportion is devoted to locusts, of which 

 there have been already no less than 273 species identified on 

 the North American Continent, north of Mexico ; " and," says 

 the author of the report (Mr. Lawrence Bruner), "probably 

 many others remain to be discovered." He continues "All these 

 are more or less injurious to the agriculturist, and to those who 

 are in any way dependent upon products of the soil for their 

 living." The remarks upon these insects are most exhaustive 

 and interesting; for not only do they deal with locusts in 

 America, but an appendix reviews their history as known in 

 other parts of the world, especially in China and Russia. 



So important is the subject of the Hessian fly (Cecydomia 

 destructor) a very small dipteron, which is allied to our familiar 

 daddy-long-legs or crane-flies, that ninety-three pages and a map
