not for the stripe along internal margin in Ahdominalis. This, 

 although narrower than the costal edging, is quite plain in my 

 species. Away from my books and collections, I thought that I 

 was possessed of a new Zygcsnid type when I took the specimen 

 in Alabama. 



A table of the three species might be made as follows : 

 Fore wings bluish cinereous or lead color. 

 Fore wings with costa and internal margin striped. 

 Stripes crimson. — Spraguei. 

 Stripes dark yellow. — Ahdominalis. 

 Fore wings with costa striped. 



Stripe pale luteous. — Eglenensis. 



1. EucH.^TES Spraguei, Gr. Can. Ent., vii., 200. 



<? . Allied to Elegans, but entirely stone color, like Egle. 

 Fore coxae, head at base, two thoracic vittae, costal and internal 

 margin of fore wings crimson. Abdomen above red, with dorsal 

 black dots. Kansas. Prof. Snow. 



2. EuCHyETES Eglenensis, Clem., Proc. Ac. N. S., Phil., 

 533, i860. 



Bluish cinereous. Palpi bright reddish at the base, with dark 

 cinereous tips. The occiput and post orbits are red orange. The 

 external edge of the fore wings is pale luteous. The abdomen 

 above is bright red-orange, with a dorsal row of small black 

 spots and one on each side; beneath, cinereous. The thorax 

 beneath and the anterior coxae are tinged with red orange.

3. EucH.ETES Abdominalis, Gr., Can. Ent., 124, 1871. 



? . The wings are lead color ; in certain lights the primaries 

 show a bluish reflection, as in CtenucJia. The costal region of the 

 fore wings above and below is striped with dark yellow, as in the 

 internal margin. The hind wings are concolorous. Abdomen 

 above orange, with a dorsal and lateral series of black spots ; be- 

 neath, lead color. Palpi, throat and head behind and between 

 the antennae bright orange ; front dark, as are the palpal tips. 

 Legs dark lead color. Fore coxae orange. Collar and tegulae more 

 or less evidently edged with orange. Expanse a^^vcvX. Alabama. 

 A front wing and a denuded hind wing, mounted on card-board, 

 are all that remain of the type, which I discovered among some 

 broken specimens in a forgotten box. 



There is a curious resemblance between the species of Ctenu- 

 cha and EuchcBtes, so that the darker forms of the latter genus 

 might be mistaken for Zygcenids were it not for the Arctia-Y\\iQ 

 abdomen. The denuded hind wing of my type oi Abdominalis is 

 8-veined ; veins 3, 4 and 5, equidistant at base, thrown off from 

 extremity of median vein. 



The three "species " here discussed are the prettiest in the 

 genus, and of the three Spraguei is the handsomest and most dis- 

 tinctly colored.
