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 
kauaiensis, particularly in the tegminal development. That author’s 
fusconotatus appears to be based on a larger male of forficularis, 
such as those from Lanihuli and Mount 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 xxvu, 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 
Oahu and Kauai have conspicuously annulate limbs.
