Through the kindness of Dr. Alvah Peterson I recently 

 came into the possession of several specimens of the larvae 

 and pupae of the Rhinoceros Beetle (Xyloryctes satyrus Fab. >. 

 which he had reared and it seemed desirable to describe these 

 stages and to bring together the notes of various authors on 

 the larval habits. Dr. Peterson's material was collected at 

 Urbana, Illinois, in a deciduous woods from soil rich in humus 

 and heavily mulched with leaves. Dr. Adam Boving. Bureau 

 of Entomology, Department of Agriculture. Washington. 1). C.. 

 has called my attention to J. C. Schiodte's monographic treat- 

 ment of the Scarabaeid larvae in the Zoological Museum of 

 Copenhagen, Denmark. He also suggested that I prepare my 

 description of the larva of Xyloryctes in almost exact conform 

 ity with Schiodte's descriptions of Scarabaeid larvae. This 

 suggestion I have been glad to follow. The figures aerom- 

 panying this paper were made by Dr. Boving.
