 1912-1913 (Friederichs) ; Vailima, 1 19.iii.1924. 



Savaii : 1 $, June, 1905 (Rechinger). 



Tutuila: 3 3 (Kellers) ; Pago Pago, 9 11$?, bearing the following 

 dates 14, 21. ix., x.1923, i, ii.1924 (Steffany). 

 Manua : Ofu, 3 1 ?, 27.ii.1926 (Judd). 



I suspect that this species may prove to be another of which further study 

 will provide us with evidence of geographical variation. The type is a female, 

 and I can find no evidence to show exactly whence it originated, neither can I 

 exactly match the female genitalia. Much more material from other islands 

 in the Pacific Ocean is required before adequate studies of these interesting species 

 can be made. The Samoan specimens are, as far as I can at present judge, 

 superficially indistinguishable from the type.
