ETUDES DE LEPIDOPTEROLOGIE COMPAREE. Vol. XIV, 1917. By CHARLES 

 OBERTHUR. This volume consists of 474 pages and numerous plates. 

 Probably the parts of most interest to the American student are the 

 studies and genitalic illustrations of the genus Lycacna. Doctor Jacques 

 Reverdin presents an illustrated article on Lycacna arans and its va- 

 rieties. Dr. T. A. Chapman describes a new species, Lycacna acgns. 

 This is closely related to our species, mclissa, and the author says 

 aster from Labrador does not differ to a specific extent from incl'.ssa. 

 The types of aster came from Newfoundland. Dr. Chapman's paper b 

 illustrated by 20 plates. This is followed by a beautifully illustrated 

 article on Actiiinte by M. Oberthiir. with n plates in color. M. F. 

 Le Cerf contributes an article on the Aegeriidae with seven plates. 

 This contains species of our fauna and also some new genera and 

 species are described. Biological observations and figures of certain 

 species of Lycacna are given. The work is up to the beautiful standard 

 of those preceding it and is a splendid contribution to lepidopterologi- 

 cal studies. HENRY SKINNER.
