Of the specimens from the island of Hawaii, the Niulii and 

 Olaa District individuals agree closely with the condition described 

 by Perkins as similis, the limbs showing scarcely a trace of annula- 

 tion. The Waimea District female is similar, but has the limbs 

 distinctly annulate, the annuli by no means so deep and contrasting 

 as in most of the specimens from the island of Oahu. 



The female from the island of Kauai, and the specimens from 

 Kaumuohona Ridge, Mount Olympus and Palolo, on the island of 

 Oahu, agree rather with the condition described by Perkins as 

 kaitaiciisis, particularly in the tegminal development. That author's 

 fusconotatns appears to be based on a larger male of forficiilaris, 

 such as those from Lanihuli and ]\I<)unt Tantalus, on the island 

 of Oahu, here recorded. In these specimens the metanotum shows 

 a weak median twin convexity, with an impressed point mesad on 

 each side (Plate xxvii. 10). The Kaumuahona, Oahu, male not 

 only appears to be immature but has the metanotum unspecialized. 

 The other two Oahuan males show high metanotal specialization 

 beneath the tegmina (Plate 11, fig. 11 ). All of the specimens from 

 C)ahu and Kauai have conspicuously annulate limbs.
