opposite the discal dot. Beneath, the hind wings are pale sulphur-yellow, 

 like the fore wings, and the markings all re-appear, but the discal dots and

 and much more distinct. Legs yellowish, tinged irregularly, and banded 

 with pale fawn-color. - 



Length of body, 0.50 ; of fore wing, 0.65 ; expanse of wings, 1.35

Bright sulphur-yellow; abdomen and hind wing paler. Front of the
