MICROLEPIDOPTERA OF PHILIPPINE ISLANDS 219 



The large fat body, as in most wood feedei's, makes the set specimens 

 quickly greasy and hard to study. 



Also the present material has other drawbacks. Several species 

 are represented by a single worn specimen. Therefore, their generic 

 attribution is somewhat arbitrary. For the same reason, I abstained 

 from describing new genera. 



Key to the Philippine Genera of Aegeriidae 



1. Forewing with veins 7 and 8 coincident Adixoa 



Forewing with veins 7 and 8 stalked 2 



2. Hindwing with veins 3 and 4 separate 3

3. Hindwing with vein 3 closer to 2 than to 4 Melitda 



Hindwing with vein 3 closer to 4 than to 2 4 



4. Abdomen with lateral tufts of hairs toward extremity; forewing for the 



greater part colored Sura 



Abdomen wathout lateral tufts, but with a large, spreading anal tuft. 



Paranthrene 



5. Hindwing with veins 3 and 4 connate; hindtarsi with basal segments long- 



haired Trilochana
