Admiilvlty Islands : 2 specimens ; Los Negros, 1 specimen. Solo- 

 mon Islands : Guadalcanal, 17 specimens ; Kussell Island, 1 specimen ; 

 New Georgia, 3 specimens: Florida Island, 4 specimens; Treasury 

 Island, 1 specimen ; Bougainville Island, 7 specimens. 



The type of M. a. stnatofasciata was from Ralum, in the Bismarck 

 Islands, and Hennig reports the subspecies from Mioko (Duke of 

 York Island, 1935) and New Britain (1937). Our Admiralty Islands 

 material is most nearly typical, with distinct wing bands and a strong 

 hind femoral pattern, including a distinct preapical dark band. 



A wide variation exists, however, in the coloration of this form 

 and although some evidence of a cline toward the east is present, 

 some of the specimens from Bougainville, Florida, and New Georgia 

 approach those from the Admiralties.

Mimegralla albimana extrema Hennig, Konowia, vol. 14, p. 203, 1935. 



New Hebrides: Espiritu Santo (Turtle Bay and Segond Channel) 

 29 specimens. 



This form was described from Pentecost Island and Malekula Island, 

 also in the New Hebrides. It is a large and distinct form.

 Mimegralla albimana tongana (Czerny) Hennig, Konowia, vol. 14, p. 203, 1935. 



I have not seen specimens of this form, which was described from 

 the Tonga Islands. 



3k. MIMEGRALLA ALBIMANA KEIENSIS Henni? 



Mimegralla albimana Jceiensis Hennig, Konowia, vol. 14, p. 201, 1935. 



Not seen by me. It was described from three female specimens 

 from the Kai (Kei or Key) Islands. It is likely that it is but a variant 

 of M. a. sepsoides, which is known from the neighboring Aroe (Aru) 

 Islands.
