 described by me from Colorado. Its resemblance to the Unssian 0.

Tlie eyes are naked, with lashes. Antennae simple, pubescent, slender. 

 The form is frail ; the vestiture of the thorax is composed of flattened scales 

 with a slight admixture of hair; dorsum of the abdomen strongly tufted 

 centrally. Primaries wide, with retreating inner angle. The genus differs 

 from Hadena by the vestiture of the thorax which is not hairy but scaley. 

 The species is fragile and seems to me related to Homohadena badistriga. The 

 ornamentation, while peculiar, still recalls that species and the thoracic vesti- 

 ture is similar in character, while the shape of the wings and the dorsal body 

 tufts afford characters of structural dissimilarity. 



(14.) Chytonix iaspis (Guenee). 



S . — The body is slender. Antennae thin and pubescent beneath. Abdomen 

 strongly tufted. Wings ample. Primaries pale brown. T. a. line broad, 

 dark brown, nearly even, outwardly oblique. Median space wide owing to 

 the course of the fine and double t. p. line, which is widely and roundedly 

 exserted over the nervules and runs gradually inwardly to internal margin 

 where the two lines approach, and towards which the median space gradually 

 narrows. A deep blackish brown broad shade on the submedian fold runs 

 across the median space and includes just before the t. p. line a well defined 

 snoiD-wMte spot. Ordinary spots large concolorous, double ringed. The ter- 

 minal space is very narrow, even, darker than the pale brown shades which 

 precede the pale irregular subterminal line. Terminal blackish brown line 

 very distinct, sub-continuous ; fringes dark, narrowly cut with pale. Hind 

 wings fuscous with pale fringes. Beneath pale whitish fuscous with a discal 

 dot and a rivulous median line on hind wings.

$ . — Allied to H. Ugnicolor and JI. litJioxylea, but a stouter and heavier spe- 

 cies. The whole insect is of an even dull orange brown, hence there are no 

 ferruginous shades or streaks on the primaries as in Ugnicolor. Ordinary spots 

 concolorous, hardly perceivable, with pale annuli ; reniform a little smaller 

 and more excavate, orbicular notably more elongate than in Ugnicolor and 

 attaining the reniform or very nearly so. T. p. line pale, hardly perceivable.
