pointed and in glorieUa, distinctly truncate. The female genitalia of 

 gloriella resemble those oijloridalis and albescens, but are distinguished 

 from them by differences in the tonguelike projection; in both floridulis 

 and albescens the median area of the bifurcation is rather deep and 

 distinctly angulate; in glorieUa it is shallow and broadly concave.

Alar expanse: Male 15-18 mm.; female 17-19 mm. 



Frons round. Head and thorax whitish; palpi ochreous white, 

 mixed with pale fuscous laterally and distally. Forewing: Upper sur- 

 face white, with an ochreous tinge, moderately irrorated with brownish 

 fuscous. Medial line pale buff, origin from near middle of costa, 

 broadly concave outward, loop enclosing the cell extending but slightly 

 beyond end of the cell; thence straight or but slightly sinuate and 

 oblique inward, terminating on inner margin before middle. Inner 

 and outer margins of subterminal band pale buff, straight or but 

 slightly incurved between veins lb and 3. Interspace of veins ochreous 

 from termen to subterminal band. Terminal line discontinuous, as 

 blackish patches. Fringe metallic. Hindwing: Upper sm'face whit- 

 ish, with a slight ochreous tinge. Fringe white. 



Male genitalia (figs. 1-lb) : Symmetrical. Costa of dorsal basal 

 lobe of harpe broadly triangulate in shape; the toothlike projection 

 slender, concave, bluntly pointed distally. Aedeagus slender, with 

 numerous small spinules and a toothlike projection near middle of a 

 long, narrow, straplike sclerotization. 



Female genitalia (fig. 18): The tonguelike projection bifurcate, 

 apices bluntly pointed; median area of bifurcation acutely angulate, 

 rather deep. Ventral margin of ostium weakly sclerotized, convex. 

 Ductus bursae longitudinally rugose for almost its enthe length. 

 Ductus seminalis with origin about midway between ostium and junc- 

 tion of ductus bursae and bursa copulatrix. Signa two small, round, 

 weakly scobinate, sclerotized patches. 



Type: Male, in U.S. National Museum, USNM 11956.
