ity record, and the collections in which the various species are 

 located are also indicated. . 



The writer greatly appreciates the loan of material during his ] 

 study of this family and wishes to thank the following entomologists 

 for their assistance: Nathan Banks, Museum of Comparative Zool- 

 ogy, Cambridge, Mass., for a collection made by Dr. W. M. Mann in 

 Haiti ; Dr. Henry Skinner, for a collection from the Academy of 

 Natural Sciences of Philadelphia, containing the Poey collection 

 from Cuba ; Dr. W. J. Holland, for material from his private collec- 

 tion, as well as for the loan of material from the Carnegie Museum 

 of Pittsburgh, collected on the Isle of Pines and Jamaica; Prof. 

 H. F. Wickham, University of Iowa, for material from the Bahamas 

 and Haiti; and George N, Wolcott, of the Insular Experiment 

 Station, Rio Piedras, Porto Rico, for material collected in Porto 

 Rico. G. B. Merrill, Gainesville, Florida; E. G. Smyth, Bureau ! 

 of Entomology, United States Department of Agriculture; and 

 Frank B. Mason, Philadelphia, have also furnished valuable addi- 

 tions to the material studied. Stephen C. Bruner, chief of the ! 

 Department of Entomology and Vegetable Pathology, Estacion Ex- j 

 perimental agronomica, Santiago de las Vegas, Cuba, has sent an j 

 interesting collection taken in Cuba, and has also examined the I 

 material in the Gundlach Museum at Habana and furnished the 

 writer with a list of the species contained in that collection. The 

 writer is under great obligations to Dr. F. E. Lutz and A. J, 

 Mutchler for the loan of a valuable collection from the American 

 Museum of Natural History, including collections made by the ex- 

 peditions conducted by that museum to the various islands in the 

 West Indies, and also those made by the New York Academy of Sci- 

 ences in conjunction with the museum, as well as other material col- 

 lected by private individuals and sent to that museum for identifica- 

 tion. I am especially indebted to Dr. Charles J. Gahan for the 

 loan of material from the British Museum. This collection con- 

 tained many species which had been compared with the types of 

 Thompson, Gory, Chevrolat, etc., by the late Charles O. Waterhouse, 

 and has been of the greatest help in my studies. 



The writer desires to express his deep appreciation and sincere 

 gratitude to Dr. E. A. Schwarz, of the United States National 

 Museum, for the many helpful suggestions during the course of the 

 work, for his kind and valuable criticism, and for aiding generally 

 in every possible way in the preparation of this paper.
