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," 



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

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

 to rel}' on the accuracy of descriptions, in the construction of 

 these tables. 



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

 Omiodes hlackhnrni, 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 s'mple 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) PYRALIDl'NA 



Hind wings with Ic absent 2. 



2. Antennae terminally clavate (C) PAPILIONlNA. 



Antennae not terminally clavate 3.

 Forewings with 5 parallel to 4 or approximated to 6 



(B) NOTODONTINA. 



(A) CARADRININA. 



]. Hindwings with 5 well developed (I) CARADRl'NIDAE. 



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

1. Eyes hairy Leucania. 



Eyes not hairy 2. 



2. Middle and posterior tibiae spinose 3. 



Middle and posterior tibiae not spinose • -4. 



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



Heliothis. 



Anterior tibiae with more spines than above. Agrotis.
