NUDARIAf, Hawoiitii. 



This is anotlior curious genus, distinguished by its subhyaHue rounded wings, wliicii are present in botli sexes, 

 slender setaceous antenuie, slender recurved palpi, and long sjiira! tongue ; the pusteostal vein is jieculiar, on account 

 of its emitting three branches of equal length close to the tip of the fore wings. The caterpillars are clothed with 

 very long hairs. They do not form portable cases ; and the chrysalis is slender and silken, with the hairs of the 

 caterpillar interwoven. As suggested by Curtis and Boisduval, the genus seems to be nearly related to the 

 LithosiidiB.

 Tills .species, regarded by some authors as a variety of the preceding, differs from it in being of a smaller 

 size, with the wings colourless and iridescent, without any spots or markings ; the veins being slightly luteous, 

 and the fringe' yelhiwlsh. Specimens agreeing with this description have been reared by different collectors, 

 as vvell as taken at large ; but the species is rare.
