a broad black line across the posterior tip; patagiiia white. Fore- 

 whigs white mth black and golden yellow markings; costal edge 

 black at base, golden yellow on the outer half; from the black part 

 run three nearly parallel transverse lines across the wing to dorsum, 

 one near the base of the wing, one at basal fourth, and one near the 

 middle of the wing; adjoining the last of these lies a large square 

 golden yellow dorsal spot, black margined also posteriorly and partly 

 on top and below; on the apical half of the wing is a spider-web of 

 five black lines radiating from a black, white-centered ring; two of 

 these irregular Imcs run to the costal edge, one joins the exterior black 

 edge of the yellow dorsal spot, one goes to the dorsal edge and one 

 joins a transverse black line across the wing at apical fifth beyond 

 which the tip of the wing is golden yellow. Hindwing light golden 

 fuscous. Abdomen dark fuscous with underside and anal tuft 

 saffron yellow. Underside of thorax silvery white. Legs yellow, 

 tarsal joints slightly tipped with black. 



Alar expanse. — 19-20 mm.

Type-specimen.— Cat. No. 16695, U.S.N.M. 



A clearly marked, pretty species, nearest to the larger E. dellieUa 

 Fernald, from which it is at once distinguished by the large yellow 

 dorsal spot, and to E. cypraeella Zeller, from Venezuela.

Second joint of labial palpi black; terminal joint dirty white. Face 

 blackish. Head white ; collar narrowly black. Thorax white with a large 

 central spot and a posterior transverse streak bluish black; extreme 

 posterior tip white. Forewings white suffused along the costa with a 

 smoky brown color more widely along the middle, wliere two blunt lobes 

 of this color reach into the cell; on basal fourth lie six bluish black 

 metallic spots, four above the fold and two below it; on the middle 

 of the dorsum rests a large semichcular bronzy brown spot edged 

 above on the middle of the cell by an elongate smoky brown streak, and 

 transversed by a thin interrupted silvery blue zigzag line; apical 

 part of the wing is similarly bronzy brown; also transversed by a 

 thin white zigzag line and edged toward the base of the wing by a 

 cloudy smoky brown area; two detached smoky brown dots lie be- 

 tween this and the large dorsal spot; cilia smoky brown with silvery 

 white base. Hind wings shiny dark fuscous with white cilia. Abdo- 

 men dark fuscous above, with third joint velvety yellow, silvery white 

 laterally and with a deep black ventral streak; anal tuft saffron yel- 

 low. Legs smoky brown exteriorly, silvery white on their inner 

 sides.
