etc. With these may be reckoned the members of the South Florida 



colony of Moths, species like Cautethia Grotei, also found in Cuba, and 



many others. Finally, the thoroughly domiciled Southern element is seen 



in such genera as Ifyperchiria, of which we have four or five species, the 



most widely disseminated of which is JI. To, a form not reaching the 



tropics and becoming somewhat variable in the Southern States. This 



genus is numerous in South and Central American species. Our prettiest 



species of Hyperchiria is, perhaps, H. Zephyria, from New Mexico and 



Arizona, in which the dark primaries have a white stri^De running from 



apex to middle of internal margin. The hind wings are yellow with a 



large central ocellus and pink hairs at base ; the thorax is fuscous, marked 



with white on the sides, and the abdomen is fawn color shaded above 



with red.

NOTICE OF DR. WILH. MULLER'S WORK ON THE SOUTH 

 AMERICAN LARV.E OF THE NYMPHALID.^. 



BY A. R. GROTE, A. M., BREMEN, GERMANY. 



Readers of The Canadian Entomologist .have, no doubt, through 

 the papers of W. H. Edwards, followed with interest the discovery of so 

 many facts bearing on the evolution of species in the Butterflies. We 

 have now a work by a German writer of remarkable industry and ability, 

 on the larval peculiarities of the Nymphalidae, which deserves the study 

 of all interested in Lepidopterology in America. The work is adorned 

 by four plain lithographic plates of the caterpillars and their peculiar struc- 

 ture, of such fineness and softness of execution that, with all my experi- 

 ence, I hardly know where to find their equal. The work itself is a sep- 

 arate part of my friend Prof. Spengel's very useful " Jahrbiicher," a 

 zoological publication which deserves to be largely encouraged. The 

 publication may be obtained at the office of Gustav Fischer, Jena, Ger- 

 many, and this work on the Nymphalidge costs about three dollars (ii 

 marks). The book itself (252 pp.) is too lengthy to be adequately re- 

 viewed here. It is a minute study, throwing light on the genealogy of the 

 family from the structure of the caterpillars, and it is conducted with an 

 ability which is simply marvellous. Only in this way can Ave become 

 acquainted with the ancestry of our present Lepidoptera, a study which is 

 perhaps the most fascinating suggested by these insects, and which has 

 only become possible since Mr. Wallace and Mr. Darwin opened the 

 doors to this field of speculative inquiry.
