4. ALBERADA, new genus 



Genotype. — Melitara parahates Dyar. 



Antenna of male bipectinate, of female pubescent. Labial palpus 

 porrect and downcurved. Maxillary palpus squamous. Hind wing 

 with veins 7 and 8 anastomosing beyond cell; 3 and 5 stalked. 

 Eighth abdominal segment of male simple. 



Male genitalia with apical process of gnathos bifid, the two prongs 

 rather widely separated; harpe with the apex evenly rounded; vin- 

 culum short; anellus with base of plate narrowly sclerotized, arms 

 moderately long and stout ; aedeagus stout, weakly sclerotized in mid- 

 dle except on midventer. 



Female genitalia with signum developed as a ridged plate; bursa 

 copulatrix finely scobinate and wrinkled ; ductus seminalis from mid- 

 dle of bursa. 



Larvae bluish, not banded; solitary feeders in the joints of Cylin- 

 dropuntias. 



Eggs laid singly or in masses of two or three. 



Remurks. — The genus is close to Melitara., differing in the follow- 

 ing characters: Veins 7 and 8 of hind wing anastomosed, 3 and 5 

 stalked, aedeagus only partially sclerotized, apical process of gnathos 

 with prongs well separated, bursa copulatrix with signum. 



The distribution is apparently limited to Mexico and the south- 

 western part of the United States.
