AMEBICAN MOTHS OF THE SUBFAMILY PHYCITINAE

ish color of forewing, the basal area being but slightly if 

 any paler than the remainder of the wing. The color 

 differences noted by Dyar among his supposed Panamd 

 species are not so great as the variation exhibited by the 

 Puerto Rican series of quantulella and the palpal differ- 

 ences he stresses are purely imaginary. The heads of his 

 specimens were so badly battered and the palpi so dis- 

 torted it would be impossible to determine their exact 

 lengths, shapes, or scaling even if there were such differ- 

 ences, which there are not. I have grave doubt that 

 coca is anything but a local form of quantulella ; but ia the 

 absence of any examples of Erelieva from the mainland 

 between Panamd and Texas it seems best to retain coca 

 as a specific designation until more material is available. 



The genitalia are not significantly different from those 

 of quantulella. 



Type localities : Taboga Island, Panamd {coca and 

 uncta, in USNM); La Chorrera, Panamd (coquilla, in 

 USNM) ; Taboguilla Island, Panamd {mossa, in USNM). 



Food plant: Unknown. 



The only specimens I have seen are the 13 specimens 

 (a male and 12 females dated Feb. and May) originally 

 associated by Dyar with his several names and one 

 female from Corazal, Panamd (Mar.), which he had 

 erroneously associated with his female type of "Eu- 

 rythmia vestilla," the latter, itself, a synonymy of 

 Ephestiodes plorella.

Forewing brown with a very sparse dusting of whitish 

 scales and a glossy sheen in contrast to the duller ap- 

 pearance of quantulella and coca; transverse lines 

 straight, narrow, the antemedial line more distinct than 

 in the other two species; veins 3 and 5 very shortly 

 stalked. Hind wing glossy fuscous; veins not appreci- 

 ably darker and termiaal margin but faintly so. Alar 

 expanse, 11-12.5 mm. 



Male genitalia not appreciably different from those 

 of quAintulella. Female genitalia with from 5 to 7 signa 

 and a spiral of small spines at junction of bursa and 

 ductus bursae and extending into the ductus. 



Type locality: East River, Conn, (type in USNM). 



Food plant: Unknown. 



A distinct species, distinguished by its glossy brown 

 forewing, its darker hind wing, fewer signa, and the spiral 

 spining at junction of bursa and ductus bursae. It is 

 represented in the National Aluseum by a good series 

 (37 specimens) collected by Ely in July 1909 and 1910 

 at the type locality; but, so far as I know, has not turned 

 up since from any other locality. It may be indigenous 

 to the northeastern United States or an invader from 

 the Tropics. I suspect that it is the latter.
