are studied. Interesting studies of the genitalia of Acraea are given 

 with figures of the organs of generation. Certain species of the Ly- 

 caenidae, Satyridae and Hesperidae are studied and figured, and among 

 the Heterocera certain species of Agaristidae, Saturnidae, Noctuidae 

 and Nyctemeridae. The fifth part of the text is devoted to biological 

 observations by M. G. Melou. The volume closes with remarks by M. 

 Oberthiir. 



There are fifty-six colored plates with 448 illustrations. These plates 

 for accuracy and beauty have never been surpassed and seldom equalled. 

 Of these many illustrations, 185 are devoted to the tropical American 

 genera Catagramma, Callicore and Perisama. They are now on a 

 much firmer basis for study as not much has been added to our knowl- 

 edge of these butterflies since the time of Hewitson. The geographi- 

 cal individual variation is quite remarkable and is well shown by Mr. 

 Oberthiir in the excelsior group, where the undersides of the insects 

 are practically alike, and the uppersides show much variation. It is al- 

 ways a pleasure to see a volume of the Etudes appear. HENRY SKIN-
