SOME ACCOUNT 



OF THE 



'PALAN'BYOO' OR 'TEINDOUNG BO' 



( Paraponyx oryzalis), 



A LEPIDOPTEROUS INSECT-PEST OF THE RICE-PLANT IN BURMA 

 WHICH IN THE CATERPILLAR STAGE BREATHES WATER BY MEANS 

 OF TRACHEAL-GILLS. 





TN January 1882, two specimens (two stages) of a 

 blight which attacks the Rice-plant, the one called in

 and they represent two of the stages in the metamorphosis
