readers are probably already prepared to adopt, except possibly 

 as it affects the relative position of the Rhynchophora. 



The Rhynchophora were regarded by Leconte practically 

 as a suborder, strongly differentiated by the rigid palpi, single 

 gular suture, legless larvae and, usually, by the beak. A con- 

 tinuance of this division would still permit of ending the Coleop- 

 tera genuina with the heteromerous, phytophagous and lamelli- 

 corn series in successively advanced rank, and avoid interpolat- 

 ing the Rhynchophora between them. Furthermore the Rhyn- 

 chophora as a suborder would be more logically connected 

 through the Brenthidse with the Rhysodidse of the Adephagous 

 series, and through the Anthribidse with the Bruchidas of the 

 Phytophagous series, than they would be if regarded as merely 

 a series of equal taxonomic value with other series. I should 

 therefore personally prefer to transpose the position of families 

 90 to 93 so that they would follow families 94 to 97, but separated 

 as a suborder so as to leave the Scarabseidse at the end of Coleop- 

 tera genuina. 



On this as well as on the minor points covered by the notes I 

 shall be glad to receive the comment of the reader. No such 

 changes, however based purely on personal opinion, have been 

 here made ; the arrangement of the families follows that of Brues 

 and Melander except as noted below where there is a conflict of 

 authorities.
