134 Christmas Island, 



nearly parallel to the hind margin ; within the middle of this runs 

 a narrow vitreous stripe coveiing the outer half of seven cells ; one 

 or two very ii-regular series of transverse cells beyond the middle 

 of the wing, not even uniform on both sides ; inner marginal region 

 tinged with yellow, but less strongly than the costa ; costal cross- 

 nervures not forked, but most of the apical nervures beyond the 

 stigma and on the hind margin are forked. Hind wings hyaline, 

 brown along the hind margin, the first six or seven marginal 

 nervures from the tip furcate or bifurcate. 



"The neuration of this and the two following species somewhat 

 resembles that of R. panorpcsformis, Guer. JS'o dates of captui'e 

 are attached to anj of the specimens." 



Two specimens: Flying Fish Cove, August, 1897, and East 

 Coast, October, 1897.

'•'■Male. — Yery similar to the last species, but darker above, the 

 brown bands on the clj'peus beyond the inner carina darker ; 

 undersurface of body yellow, with iiTegular black markings 

 beneath the wings, and a large spot on the pectus between the 

 two first pairs of legs ; abdomen not banded with green above, 

 but with a row of yellow spots on the sides. Wings hyaline, not 

 tinged with yellow on the costa or inner margin, but with a yellow 

 spot on the costa (likewise edged with black within) before the 

 black stigma ; below the stigma are some small brown blotches 

 along the line of the inner row of transverse cells ; there are also 

 two small brown spots nearer the base on the lower half of the 

 wing ; hind margin brown for about one -sixth of the width of 

 the wing, and marked with two irregular hyaline spaces, each 

 covering several cells ; close to the hind margin runs an inteiTupted 

 row of small hyaline dots. Hind wings hyaline, edged with 

 brown, except towards the anal angle. jS'euration nearly as in 

 the last species, but the outer row of transverse cells less 

 numerous."
