hind tarsus clay-colored, the terminal one light green, the claws green, 

 black-tipped. Tegmina darker than the rest of the body, the sides 

 marked by two large dusky blotches confined to the lateral sloping 

 surfaces ; apical part with small dark brown quadrate spots. Ab- 

 domen uniform pale yellowish clay-colored. Length of tegmina 19 

 mm. 



Variations (17 specimens). — Thirteen of the specimens have the 

 stripes of head and thorax as described for the type^ although they 

 vary much in distinctness. Four are so uniformly pale-colored that 

 they show only the faintest Indications of the stripes. None of them 

 show the slaty genae of the Indefatigable and Albemarle specimens, 

 although a pale coloration of the genae is a common characteristic. In 

 many the diverging lateral stripes of the dorsum of the metazona show 

 plainly, but in others they are either wholly wanting or are present as 

 mere suspicions. Two specimens have the longitudinal angles of the 

 closed tegmina, pale clay-colored, forming two very conspicuous 

 posteriorly converging stripes of the same color as the entire dorsal 

 surface of the closed tegmina — a marking characteristic of S. trinesiotis 

 indefatigabileiisis. In only three specimens do the lateral blotches of 

 the fore wings encroach on the dorsal surface of the wings, and in 

 none do they form complete transverse tegminal bands. All the speci- 

 mens have the hind tibiae closed like those of the type^ or on the same 

 pattern, the bluish tinge being generally lacking and the color simply 

 brown or dusky. The degree of coloration varies considerably, but 

 the specimens differ uniformly from those of any other island in having 

 the lower three fourths to four fifths of the tibiae continuously dark- 

 colored. In most of the specimens the spines are dusky basally, 

 instead of yellowish as in the type. The green color of the third 

 tarsal joint also is not a constant character, this segment being gener- 

 ally the color of the first and second segments.

The color pattern of the type is almost exactly that of S. trinesiotis 

 indefatigabiletisis., but the markings are less distinct. The pale 

 supra-post-ocular stripes of the head are continuous across the prozona 

 with the diverging stripes on the angles of the metazona. It shows 

 most highly developed the pattern faintly indicated upon some of the 

 Albemarle specimens. The Chatham race is certainly more closely 

 related to the Indefatigable form than to any other, but it strongly re- 

 sembles the Hood race in being of a uniform, pale, reddish-brown 

 color and in having the lower part of the hind tibia dusky. On the
