INTRODUCTION. 
Tus Volume is devoted to the enumeration of three families of Rhynchophora—the 
Brenthide, Scolytide, and Anthribide,—which have been dealt with by Dr. D. Sharp, 
Mr. W. F. H. Blandford, and Dr. K. Jordan respectively. These families are all well- 
represented in Central America, as noted by the authors in their introductory remarks 
(pp. 1, 2, 81-88, 299, 300), the total number of species being as follows :—Brenthide 
140, with 104 new; Scolytide 271, with 181 new; and Anthribide 193, with 148 
new. One species of Brenthide and ten of Scolytide have since been added by other 
authors, and a list of these is appended at the end of the Volume. Of the fourteen 
Plates, three are devoted to Brenthide, six to Scolytide, and five to Anthribide: the 
first nine have been drawn by Mr. E. Wilson, of Cambridge, and the remainder by 
Mr. H. Knight, these latter being coloured.
