This Texas specimen should still he in the Leconte collection. This 

 extends its distribution previously known to cover only Florida and 

 the District of Columbia. 



The name Eiidocimus Schonherr, 1836, is preoccupied by Wagl., 

 1832, for a genus of birds and may be changed to Eudocimimis n.m. 



Calendra (not Calandra) seems to be the spelling used by Clair- 

 ville in Ent. Helv., I, 1798, p. 62, and throughout the text and expla- 

 nation of plate on pages following. The word is spelled with an " a " 

 once at the top of plate II. 



SCOLYTID^. 



The name Ipoidea is used instead of Scolytoidea, and Eccopto- 

 gastcr instead of Scolytus by Mr. J. M. Swaine, the most recent au- 

 thority on bark beetles, because, in his opinion, Geoffroy's description 

 of Scolytits, though the earliest, is not binomial and does not desig- 

 nate any species definitely. 



The contrary opinion has, however, been expressed in letters from 

 other friends by which it appears that the word " uninomial " in Art. 

 2, International Code, was used to cover such cases; and that the 

 word " binary " in Art. 25, having a different significance from bi- 

 nomial, is of importance. Opinion 20 (Smithsonian Publ. No. 1983, 

 p. 48) and Opinion 46 (Smithsonian Publ. No. 2060, p. 105), both 

 ratified at ensuing International Congress, have also been cited. 

 Under such rulings Geoffroy's genus Scolytus, containing one un- 

 named species, dates from 1762 and the name has priority in deter- 

 mining the name of the genus and family. 



Scolytus is certainly the earliest name, and its rejection under the 

 Rules of Nomenclature depends upon their interpretation, in which 

 opinions differ. I have therefore adhered to the earliest name; 

 though I have followed Mr. Swaine's classification otherwise. 



Thysanoes quercus Hopk. cited in Smith's List is omitted because 

 it has never been described. 



Ips terminatiis (p. 148, under Tomicus) of the Henshaw List is 

 omitted, being probably an error for tcrminalis Mann. 



The following names are omitted at the suggestion of Mr. J. M. 

 Swaine, for lack of reliable American records, north of Mexico: 

 Platypus cylindrns Fab. 

 Crypturgus pusilliis Gyll. 

 Rhopaloplcurus pumilus Chap.
