380 JOHN HAMILTON, M. D. 



Otidocephalus perforatus Horn. — Throug;b the kindness of Prof. Schniitt an 

 example of this rare species is in my collection taken near St. Vincent ; there 

 is an example in Dr. LeCoute's collection, two in Dr. Horn's, and it is said to 

 be in Mr. Ulke's. Besides these I know of no others, except that Mr. Wick- 

 ham mentions it as occurring in Iowa. Its being palid only suffused with 

 piceous, and entirely apterous, point strongly to a subterranean habit, prob- 

 ably living on bulbous or other roots, like Cylas firmicariiis does on sweet 

 potatoes and the roots of other CoHvohmlticex.

In closing this catalogue, which represents the principal entomo- 

 logical life-work of the author, extending over a period of twenty- 

 three years, it becomes a pleasure to acknowledge the uniform cour- 

 tesy and kindness extended by many entomological friends. Dr. 

 Geo. H. Horn kindly assisted and gave encouragement in the early 

 days of doubts, difficulties and ignorance, and to the present time in 

 naming species — in fact, a large proportion of the species in this list 

 have at one time or another passed through his hands. The INIessrs. 

 Henry and Edward Klages, Rev. P. Jerome Schniitt and others 

 have allowed me the benefit of their extensive collecting, and finally 

 thanks are due to the American Entomological Society for its cour- 

 tesy in permitting the work to appear under its prestaging auspices ; 

 to Mr. Paul C. Stockhausen for its elegant typography and press- 

 work ; and to Mr. Charles S. Blake, the learned and accomplished 

 entomological compositor, whose kindly supervision eliminated from 

 these pages the many errors and shortcomings in the manuscript.
