146 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 93 



Twenty-three specimens examined. 



Remarks. — It appears from the similarity in habitus, color, macula- 

 tion and genitalic structures of hlandaria and hyalinaria that only one 

 species with two varieties is involved; hyalinaria occurring in the arid 

 southwestern part of the United States (also probably the adjacent 

 northern Mexican area) and hlandaria in the more southern and humid 

 part of Mexico. The extremely immaculate examples of blan<I<n in, 

 with the lines obsolete, intergrade with the specimens of hyalinaria 

 and are distinguishable only by the slightly more glazed appearance 

 of the wings. 



3. EVITA PERPECTINATA (Schaus) 



Plate 7, Figures IS, 18A 

 Therina ? perpectinata Schaus, Ann. Mug. Nat. Hist., ser. 8, vol. 10, p. 235, 1912. 



Male. — Head, labial palpus, and thorax dark smoky fuscous; fore 

 wing dark brown, with an olivaceous tinge and metallic luster, a small 

 yellowish spot near the apex between veins 7 and 8 ; hind wing paler, 

 light smoky fuscous. 



Alar expanse, 40 mm. 



Genitalia (figs. 18, 18A) : Harpe simple, uncus stout, a strong hook; 

 gnathos with the apical process compressed, narrow with numerous 

 coarse spines ; f urea with a few spines distally ; penis with long slender 

 cornuti. 



Female. — Unknown. 



Type.— U.S.N.M. No. 17709. 



Type locality. — Ojo de Agua, Costa Rica. 



Food plant. — Unknown. 



Distribution. — Costa Eica: Ojo de Agua (Oct.). 



One specimen examined. 



Remarks. — This species, tentatively referred to Therina when de- 

 scribed by Schaus, is more closely related generically to hyalinaria 

 than any species yet studied.
