to the two characters which have led fasciata to be considered a 

 Geometer, viz., the fovea at base of primaries and vein 5 of prim- 

 aries arising from the middle of the cell, we cannot accept either 

 of these points. The so-called fovea is apparently caused by a 

 distinct bifurcation of vein 1 at the base, the space thus included 

 by veins 1 and Ic being somewhat devoid of scales, which in any 

 case are rather sparse on the underside. Regarding vein 5, all our 

 specimens show this vein distinctly below the middle of the cell, 

 rather more distant, it is true, from 4 than is usual, but slightly 

 curved downward towards 4 at the point of origin. The antennse 

 are, in our opinion, very strongly lamellate, giving practically the 

 appearance of bipectinations ; the eyes rather small and reniform. 



As there is apparently no generic name available for the 

 species, we would propose the name BARROVIA (the species 

 being taken at Pt. Barrow) with type fasciata Skin., and would 

 place the genus in the vicinity of Agrotiphila Grt., from which it 

 differs by its unspined fore tibiae and hairy vestiture. 



For generic characteristics other than the above-mentioned, 

 we would refer to Dr. Dyar's paper as already quoted. 



BOOK REVIEW. 



The L[fe of Inland Waters. An elementary text book of fresh 

 water biology for American students. By James G. Needham, 

 Professor of Limnology in Cornell University, and J. T. Lloyd, 

 Instructor in Limnology in Cornell University. The Comstock 

 Publishing Co., Ithaca, N. Y., 1916. 438 pp. Price, $3.00. 



This is a work that will appeal to many classes of readers, 

 including entomologists working in various fields of special study. 

 It deals with a subject of immense scope, which has been developed 

 gradually through the accumulated researches of innumerable 

 investigators and has only recently acquired the status of a coherent 

 science. 



The vast array of facts embodied in this literature has been 

 thoroughly sifted and assimilated by the authors, and the result 

 is an admirably planned and most attractive presentation of the 

 elements of limnology or fresh-water biology.
