As is well known, tables are only a help, and can not be de- 

 pended on exclusively in assigning specimens to their proper 

 genera ; but the fact that for many of the genera in the Fauna, 

 no characters are given, shows all the more the usefulness of 

 tables of this kind, and 1 think they will be fully appreciated by 

 those interested in Hawaiian "Macros." 



I have verified the tables for the most of the genera; but of 

 some of the rarer ones I have not seen specimens, and have had 

 to rely on the accuracy of descriptions, in the construction of 

 these tables. 



As a sample of wing venation, 1 insert a cut of wings of 

 Omiodes blackburni, the Palm Leafroller. These wings have 

 all veins present ; whereas many genera have one or more veins 

 missing. They are numbered by the method used by Meyrick 

 and others, which is more simple than that used by some Lepi- 

 dopterists. 



As tabulated, there are four Superfamilies represented; i5 

 Families ; and 6i Genera. 



1. Hind wings with Ic present (D) PYRALIDINA 



Hind wings with Ic absent 2. 



2. Antennae terminally clavate (C) PAPILIONl'N'A. 



Antennae not terminally clavate 3. 



3. Forewings with 5 basally approximated to 4.. (A) CARADRININA 

 Forewings with 5 parallel to 4 or approximated to 6 



(B) NOTODONTINA. 



(A) CARADRININA. 



1. Hindwings with 5 well developed (I) CARADRINIDAB. 



Hind wings with 5 imperfect or obsolete (II) PLUSIADAE. 



(D CARADRINl'DAE. 



Eyes hairy Leucania. 



Eyes not hairy 2. 



Middle and posterior tibiae spinose 3. 



Middle and posterior tibiae not spinose 4. 



Anterior tibiae with two apical spines and two on inner side. 



. Heliothis. 



Anterior tibiae with more spines than above. Agrotis.
