Mah. — Christmas Island; Dec, 1897 — Jan., 1898; fourteen 

 specimens. (C. W. Andrews.) 



The specimens are in poor condition, but show that the species 

 is distinct from C. aglaodesma, Meyr., not only from its smaller size 

 but from the different arrangement of the abdominal spots and the 

 tint of the hind wings, besides minor differences in the arrange- 

 ment of the markings. It is obviously an insular form allied to 

 the New South Wales species, which, however, also occurs in the 

 (Solomon Islands.
