of the two forms and their slight, but apparently consistent, color 

 differences to warrant their separation. I am therefore removing 

 subvmhrella from synonymy. 



3. Genus OLYCA Walker 



Olyca Waxkeb, List of specimens of lepidopterous insects of the British Museum, 

 vol. 11, p. 725, 1857. — Hampson, M^moires sur les L^pidoptferes, vol. 8, p. 34, 

 1901._Dyab, Proc. Ent. Soc. Washington, vol. 30, p. 133, 1928. (Genotype: 

 Olyca phryganotdes Wallcer.) 



Antennae pubescent in both sexes (the pubescence longer in the 

 male than in the female), slightly serrate in the male. Labial palpus 

 of the male obliquely ascending; of the female porrect and down- 

 curved. Maxillary palpus squamous. Hind wing with veins 7 and 

 8 shortly anastomosed beyond cell; 3 and 5 coimate (occasionally very 

 shortly stalked). Eighth abdominal segment of male simple. 



Male genitalia with apical process of gnathos bifid; harpe with 

 apex evenly rounded ; vinculum short ; anellus with base of plate nar- 

 rowly sclerotized, arms moderately long and stout; aedeagus stout, 

 moderately long, apex armed with many minute, liairlike spines. 



Female genitalia without signum; bursa copulatrix simple except 

 for a few microscopic scobinations ; ductus bui-sae short; ductus 

 seminalis from bursa somewhat caudad of middle. 



Larvae not banded, solitary in habit, feeding in Platypuntias (pre- 

 sumably in the stems). 



Eggs unknown. 



Rem<irks. — Olyca is readily separated from other genera of the 

 cactus-feeding Phycitinae having veins 3 and 5 of hind wing connate 

 by having the antennae pubescent in both sexes. 



The male genitalia are similar to those of Olycella^ differing only 

 in slight details; the vinculum is slightly shorter, the uncus broader 

 in proportion to its length, the cleft apical process of gnathos smaller, 

 the elements of transtilla longer and straighter. 



The females differ chiefly in that they lack the signum in the bursa 

 and the sclerotized plates in the opening of the ductus bursae. 



The genus as here defined contains only the type species from the 

 West Indies.
