Jle/iiOfiiuSy &€., found in the same localities. C. linus (Stoll)

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

 very like the genus Thyriilia.

This genus, which represents Castnia in Australia, includes 

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

 unlike the large American Castniidcc. The species of .Sy;/^/;/^;/ 

 are very like Hesperiidic^ 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 

 ITespcriidcc 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 HespcriidiC 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 Liischemon nij/lesicc, Doublcday, 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,
