Six examples in Fryer's collection under the name of A. caia. I 

 took a specimen in September 1886, at Sendai. 



There appears to be no constant diflference between these Japanese 

 insects and more or less typical examples of A. caia from any part 

 of Europe; but, curiously enough, not one of them agrees exactly 

 with Butler's description of E. phceosoma, although I have specimens 

 among my European series of A. caia, to which that description 

 applies ill every particular. 



The number and also the size and shape of spots on secondaries 

 are most unstable cliaracters, and no more value attaches to theiu 

 than to the excentricities of the mazy cream-coloured pattern on 

 primaries.

Of this species, which has not been previously recorded from 

 Japan, I took three specimens at Nagasaki in June, and one at 

 Shimonoseki in July. There was also one example in Fryer's 

 collection. All these are males ; the only females I have are from 

 China.

Four males : two coll. Fryer, one I took myself at Hakodate in 

 August, and one I received from a native collector.
