ffefoomus, &c., found in the same localities. C. linus (Stoll) 

 is four or five inches in expanse, and is black, with broad 

 yellowish semi-transparent bands, and white sub-marginal spots, 

 very like the genus Thyridia.

This genus, which represents Castnia in Australia, includes 

 small insects, not much exceeding an inch in expanse, and very 

 unlike the large American Castniidce. The species of Synemon 

 are very like Hesperiida^ the antennae being more or less 

 abruptly clubbed at the tips, and much more resembling those 

 of a Butterfly than of a Moth. The insects also much resemble 

 Hesperiidce in shape and colour, having oval fore-wings and 

 oblong hind-wings. The fore-wings are brownish-grey, with 

 lighter or darker markings, and the hind-wings are yellow or red, 

 with brown or black bases, borders, bands, or spots. But they 

 differ entirely from the Hesperiida in the more or less divided 

 cells, the partly open cells of the hind-wings, and in the pre- 

 sence of a frenulum, an organ not found in any true Butterfly, 

 unless Luschemon rafflesia, Doubleday, which is likewise an 

 Australian insect, is to be regarded as a Butterfly rather than 

 as a Moth. The type of the genus was originally described as 

 a Hesperia.
