THE LARVAE AND PUPAE OF THE SOCIAL BEETLES 

 COCCIDOTROPHUS SOCIALIS (SCHWARZ AND barber) AND 

 EUNAUSIBIUS WHEELERI (scHWARZ and barber) WITH 

 REMARKS ON THE TAXONOMY OF THE FAMILY 

 CUCUJIDAE

Professor W. M. Wheeler has kindly given me for study 

 larvae and pupae of the Xv^o species of social beetles discovered by 

 him in British Guiana. The material vi'as plentiful and in excel- 

 lent condition. In working out the relationship of these larvae 

 it was necessary to examine larvEe of several related groups 

 and often to avail myself of studies as yet unpublished, under- 

 taken by Dr. F. C. Craighead and myself on the classification of 

 the Coleopterous families based on larval characters. 



In addition to descriptions and illustrations of the two 

 species, mentioned above, the present contribution therefore con- 

 tains a brief discussion of the taxonomy of the entire family 

 Cucujidae. 



The different subjects are arranged as follows: 



A. The family Cucujidae, authoi-um; taxonomic remarks 

 with reference to their larvae. 



B. The subfamily Silvaninae as based on larval characters. 



B. 1. Subfamily description of the larvae of the Sil- 

 vaninae. 



B. 2. The genera of the Silvaninae, systematically de- 



fined by larval characters. 



C. Coccidotrophus socialis and Eunausibius wheeleri. 



C. 1. General morphological description of the larvae. 

 C. 2. Specific description of the larvae. 



C. 3. General and specific description of the pupae. 



D. Bibliographical notes.
