species from a single collected male. There is one other male in 

 the National collection from the type locality. These two specimens 

 are a trifle paler than normal juncfolineella and are less clearly 

 marked except for the pronounced discal spots. The transverse 

 lines on the fore wing are almost obsolete and the veins very slightly 

 indicated by dark shading. 



Inasmuch as we have no larvae or females, or any information on 

 the life history of the form from Jalapa (which is far south of 

 the known range of typical junctoUneeUa) , I do not think we are 

 justified in treating it as a mere synonym ; or, on the evidence before 

 us, as a distinct species. 



Type. — In United States National Museum. 



Type locality. — Jalapa, State of Veracruz, Mexico. 



Ejiown only from the two males from the type locality. 



3. OLYCELLA NEPHELEPASA (Dyar) 



Plate 45, FiGxmEs 87-87a 



Olyca nephelepasa Dtar, Insccutor luscitiae Menstruus, vol. 7, p. 55, 1919. 

 Olycella nephelepasa (Dyak), Proc. Eut. Soc. Washington, vol. 30, p. 134, 1928. 



Male. — Similar in pattern and general appearance to junctoline^lla; 

 but darker. The fore wing is grayish fuscous with a slight 

 brownish tint, but decidedly more grayish brown than ocherous- 

 fuscous. Also the hind tibiae of nephelepasa are heavily dusted with 

 fuscous, while those of junctoUneella are nearly pure white. 



Alar expanse, 42-44 mm. 



The male genitalia cannot be distinguished from those of juncto- 

 Uneella. 



Female. — Similar to the male except pectinations of antennae much 

 shorter, labial palpi longer, and hind wings fuscous rather than white 

 and semihyaline. 



Alar expanse, 45-52 mm. 



Female genitalia essentially like those of junctolineeUa. 



Type. — In United States National Museum. 



Tyj)e locality. — Tehuacan, Mexico. 



Food plants. — Opuntia {Plafy puntia) spp. 



Distribution. — Mexico: Tehuacan (Sept.), Mexico City, Gierna- 

 vaca, Aguascalientes, San Luis Potosi (June). 



Eleven specimens examined. 



Remarks. — The known distribution of this species is confined to 

 the central plateau of Mexico. In the National collection there is 

 one female (determined as nephelepasa) from Monclova, Mexico. 

 This specimen is colored like typical subumbrella and is, I think, 

 only a southern example of that species.
