86. Oxyodes ochreata samoana, subsp. nov. 

 (Plate IX, figs. 4, 6 ; Cf. figs. 3, 5, 7-9). 



<£. Differs from 0. ochreata ochreata in having the fuscous or warm 



sepia to fuscous black markings more sharply picked out from a deep chrome 

 ground, whereas in 0. ochreata ochreata the dark markings are more diffuse, on a 

 duller ground of orange buff. There are noticeable differences in both and $ 

 genitalia, the uncus in the of 0. o. samoana lacking the " swan's head " 

 appearance seen in the uncus of the typical subspecies.

I have come to the conclusion that the moth described by Lord Rothschild 

 (Oxyodes scrobiculata ochreata Rothschild, B. 0. U. and Woll. Exped. Snow Mts. 

 S. Dutch New Guinea, L&p., p. 61, 1915) is a distinct species, of which the material 

 here under study represents the Samoan geographical race. For the purposes 

 of properly placing these Samoan specimens I have made an extended study of 

 the three species of Oxyodes, but we still need more material in order to be 

 sure of the distribution of the various races. There are few more interesting 

 genera than Oxyodes from the point of view of the geographical distribution of 

 its species. Plate IX, fig. 8, shows the eighth ventrite of the female of the 

 Fijian subspecies, which I propose to call Oxyodes ochreata tanymekes subsp. n., 

 characterised by the elongate eighth ventrite.
