144 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 93 



Female. — Similar to brea but with upper surface of wings appear- 

 ing smoother and somewhat more reddish. 



Alar expanse, 33-42 mm. 



Genitalia (fig. 33) similar to those of brea but with sclerotization of 

 the ductus bursae extensive, extending from the genital opening to 

 the junction of ductus bursae and bursa copulatrix. 



Type.— U.S.N.M. No. 12491. 



Type locality. — Jalapa, Mexico. 



Food plant. — Unknown. 



Distribution. — Mexico : Jalapa. Guatemala : Pwrulha. Honduras : 

 (no additional information on label). 



Eleven specimens examined. 



Remarks. — The distribution and close similarity of brea and mat- 

 tearia suggest that they may represent a single variable species. With 

 only two specimens of brea it is not possible to determine the constancy 

 of the structural differences apparently distinguishing them. 



EVITA, new genus 



Genotype. — Therina hyalinaria Grossbeck. 



In addition to characters noted for the group: Apex of male an- 

 tenna simple. Fore wing with or without two transverse lines. Hind 

 wing (fig. 2A) with or without a single transverse line, veins 6 and 7 

 stalked. Male genitalia with gnathos armed with numerous stout 

 spines. Female genitalia with signum strongly sclerotized; without 

 a sclerotized band bordering ventral margin of genital opening. 



Remarks.— Closely resembles some species of Lambdina in genitalia 

 but readily separated by the stalking of veins 6 and 7 of the hind wing.
