8a. MIMEGRALLA CONTINGENS NOVAEHEBRIDEANA, new subspecies 



Female. — Length 10 mm. Preapical white fascia of wing very 

 broad, in middle a little wider than first posterior cell; wing veins 

 K. and R3 ending slightly apicad of tp; mesofrons with distinct 

 tomentum ; base and apex of middle and hind femora yellowish, apex 

 of hind femora for about one-fifth length of femora with traces of a 

 preapical dark ring, but yellowish color is rather dark and not sharply 

 delimited; middle and hind tibiae and tarsi wholly black. 



Remarks. — This race has the tomentose mesofrons of M. c. lunaria 

 and M. c. saloTnonis. The former, however, has a very narrow pre- 

 apical wing fascia and the tips of the middle and hind femora but 

 little paler, while from the latter it may be distinguished by the 

 wholly black middle and hind tibae and strong dark wing fascia.

 Hebrides: Espiritu Santo Island, Nav. Med. School Ser. No. 18/34,
