Numerous, but see text Celaenorrhinus is a genus of skipper butterflies which are commonly termed sprites.

or fifth subcostal nervule with its base almost touching that of the fourth, terminating on the outer margin far below the apex of the wing; discoidal cell long, narrow; upper disco-cellular nervule straight, strongly outwardly oblique, very short; middle and lower disco-cellular nervules almost in the same straight line (the lower a little concave), the lower a little longer than the upper, both veins taken together strongly inwardly oblique; second median nervule arising some little distance before the lower end of the cell, first median nervule arising much nearer to the base of the wing than to the point where the second median is given off; submedian nervure slightly recurved; internal nervure short and quickly running into the submedian nervure, with which it entirely anastomoses.

This diagnosis has been made from bleached wings of both sexes of the "Hesperia" leucocera of Kollar, from Simla, and of the "Papilio" eligius of Cramer from the Amazons, for the specimens of which latter I am indebted to Dr. O. Staudinger.

C. leucocera in the Western Himalayas is markedly crepuscular, I have seen specimens over and over again flying up and down a short distance of the bed of the Simla river with immense rapidity, so fast that the eye can hardly follow them, settling on a leaf for a second and then flying off again, long after the sun has set.

C. eligius, Cramer, was described from Surinam in South America, and Felder states that he has received a specimen from Venezuela.
