REi\iARKS.-^In compliance with the labels in the collection of the 

 British Museum (Natural History), J. Durrant supposed that buck- 

 leyi and purpurea might merely be the two sexes of one species. 

 The present author approves this point of view and finds especially 

 convincing the fact that the markings of the forewing are very similar 

 in both buckleyi and purpurea. The differences in the markings 

 of the hindwing may be explained by sexual dimorphism, already 

 observed in two other species of the same subgenus Eurynatteria. 

 Thus, in the males of cantharopa Meyrick these markings also are 

 more developed and confluent, while in the females they consist
