354 FAUNA HAWAIIENSIS 



Scotoryfhra diccraiinia I\Ie}T. 



Scotorythra dicei-aiiiiia Meyr. Ent. Mo. Mag. xxxvi. (1900), 258. 



Eight specimens, N.W. and S.E. Koolau range, Oahu, in July and August. 

 Previously recorded from Molokai ; I have pointed out (/.r.) that the specimen 

 erroneously assigned as the ? of goniastis is really this species. 



Scotorythra brachytarsa Mejr. F. H. i. p. 187. 

 Nineteen specimens, N.W. Koolau range, Oahu, in May, July, and August. 



ScotorytJira rara. But!. Meyr. F. H. i. p. 187. 



Fifty-two specimens, N.W. Koolau range, Oahu, in July. I have succeeded in 

 perceiving a good specific distinction between the females of this species and brachytarsa 

 in the character of the discal spot, which in rai-a is much broadened with dark fuscous 

 suffusion, whilst in brachytarsa it is quite narrow ; this distinction is easily apparent 

 when once grasped, and holds in the males also, but these can always be separated b)- 

 structure.

 characteristic.
