 front pale greenish, pink on the orbits, or entirely pink. Palpi whitish; 

 thorax green. Both wings pale green, coarsely and diffusely strigated with 

 white. Fore wings whitish on extreme edge of costa; an oblique, rather 

 broad band, straight in its course, crosses the wing from just beyond the 

 middle of the inner edge to the outer tilth of the costa: it is situated nearer 

 the outer edge in the female. No other markings. Hind wings slightly paler 

 than the primaries, with a white line just beyond the middle, broader and 

 less distinct than on the fore wings. Beneath, uniformly pale green; hind 

 wings a little paler than primaries; faint traces of the line on the fore wings.

The species may be recognized by its large size, the single line common

 der hind legs with the single pair of tibial spurs.

I (?, — This line species is intermediate between < '. nevadaria and pervi- 

 ridaria. It is of the same size as nevadaria, but the fore wings are more 

 produced toward the apex, the outer edge being more oblique; the antennae 

 arc much more heavily pectinated, while the palpi are considerably stonier. 

 From 0. perviridaria it differs in being much larger, the antenna' are a little 

 more heavily pectinated, while the palpi are stouter; the wings are also a 

 little more produced toward the apex, the outer edge being much more.
