the second, very slender and acute : maxillcB very short. Antennw as long 

 as, or longer than, the wings, joints distinct, rather stoutest in the males : 

 head small, with an obtuse tuft between the antennae : ei/es rather large, 

 subglobose : fho)-ax moderate, subovate, not crested : wings entire, anterior 

 with the costa waved, thickened in the males, and ciliated at the base in 

 the females ; hinder margin truncate, cilia very long ; disc pale ; posterior 

 wings rather small, slightly acute at the apex, and furnished with long 

 cilia : bod^ short, rather depressed, obtuse and with a tuft at the apex in 

 the males, acute in the females. 



The great length of the antenn;e of this genus at once removes it 

 from the other genera of this family, from all the preceding of which 

 it also differs in having the palpi long and recurved, a character pro- 

 minent in the following genera, and thus leading the way to the 

 succeeding family, from wliich its triangular and truncated anterior 

 wings at once remove it. There is but one species, which appears 

 about the end of July.

Anterior wings bright yellowish-red, with two minute darker, or dusky, dots 

 on the disc, an oblique purplish-brown streak towards the base, passing 

 backwards to the middle of the costa, and interrupted by a somewhat 

 oblong bright yellow spot on the extreme edge of the costa itself, on the 

 other side of which it is again continued to the apex, where it becomes 

 acutely angled, and passes along the hinder margin, vanishing at the anal 

 angle ; at the base of the costa is a second, but smaller, sulphur-coloured 

 spot, and the cilia are of similar colour : posterior wings whitish, cilia paler, 

 with the anal angle yellowish. 



Variable in colour; some examples being of a more brilliant yellow than 

 others, some of a purplish-brown, and with the markings very distinct ; in 

 some obliterated : the base of the anterior wings is frequently of a dusky 

 hue. 



Abundant in woods and gardens within the metropolitan district, 

 at the end of July and throughout the month of August; found also 

 in other parts of the country.
