our territory and do not necessarily have any significance when ap- 

 plied to extralimital forms. As far as possible I have made an at- 

 tempt to include all our described forms. A few forms as listed be- 

 low have not been included for the reasons stated. A few forms have 

 been included on characters which seem to be reliable, although I have 

 seen no specimens. In many genera recourse has been had to color 

 characters, a rather doubtful procedure, while in other genera it has 

 been necessarj^ to resort to genital characters from the one sex or the 

 other, which is apt to prove disappointing if the sex one is trying to 

 identify is the opposite sex to the one used in the key. At the present 

 time the only hope in all such cases is to collect enough material and 

 then by careful comparisons work out both sexes. For economy of 

 time and space the keys to the subfamilies, genera and species are all 

 grouped together, thus avoiding the necessity of searching through 

 several pages in locating any given form. 



The following changes in the nomenclature adopted in the Van Duzee 

 Catalog are proposed : 



Elidiptera Spinola to Epiptera Mcti-alf. 



Cyclokara vaiiduzei Ball to Patara vaiuluzei Ball. 



The geuus Lanienia Stal in our territory to Herpis Stal as lias been suggested 



by Muir; 

 The genus Cenehrea Westwood in our territory to Phacioeephalus Kirkaldy; 

 Stenocranus saccharivorus Westwood to Saceharosydne Kirkaldy; 

 Stenocranus longicornis Dozier to Meganielus Fieber; 

 Stenocranus palaetus Van Duzee to Meganielus Fieber; 

 Pissonotus piceus Spooner to Phyllodinus Van Duzee; 

 Pissonotus crawfordi n. n. for Dieranotropis marginatus Crawford nee 



Pissonotus marginatus Van Duzee; 

 Pissouotus foveatus Spooner to Pissonotus quadripustulatus Van Duzee; 

 Pissonotus variegatus Spooner to Pissonotus quadripustulatus Van Duzee; 

 Phyllodinus kcebelei Osborn to Phyllodinus flabellatus Ball; 

 Stobaira quadripustulata Van Duzee to Pissonotus Van Duzee; 

 Stenocranus breviceps Dozier to Liburnia slossoni Ball ; 

 Lil)urnia arvcnsis Fitch to Liburnia j)ollucida Fabricius;

The following species have not been included in the present re\aew 

 for the reasons stated : 

 Liburnia culta Van Duzee known from tiie female sex and I have been unable 



to place it; 

 Liburnia furcata Provancher, tlie male has not been described and I have 

 been unable to place it;
