i8o FAUNA HAWAIIENSIS 



28 specimens; 21 Haleakala, Maui, at 5000 feet; 2 Waimea Mts., Kauai, at 4000 

 feet; i Kaholuamano, Kauai, at 4000 feet; 3 Kilauea, Hawaii; i Hilo, Hawaii, at 

 2000 feet ; in January, from March to May, and in August. Closely allied to 6'. idolias, 

 but instead of being very constant it is very variable ; it differs further in the deeper and 

 brighter colouring, narrower and more lunate discal spot, and frequently larger size, as 

 also in the greater proportionate length of the abdomen and posterior tarsi of the male. 

 The female is best distinguished from the same sex of 6". rai'a by the smaller size, and 

 lighter and more ferruginous colouring. The Kauai specimens, being only females, 

 might possibly be found to represent a distinct species.
