1897.] WEST-INDIAN MICRO- J.EPIDOPTERA. 131 



Type, $ Mus. Hedemann. 



Hub. West Indies — St. Thomas, 9 III. (Hedemann). Unique. 



Though I have little doubt that this species belongs to the genus 

 Cydia, it cannot be referred there with certainty in the absence 

 of the male.

Peronea, Crt., is the oldest name for the genus, but it is too 

 close to Peroncea, Poli, 1795. Oxigrapha, Hb. (corrected to 

 Oxygrapha by Wilkinson), was monotypical from its publication, 

 and sbould therefore be cbosen in preference to any otber name 

 proposed for species of this genus by Hiibner. Teras, Tr., is 

 synonymous with Rhacodia, Hb., its type being caudana, P., 

 following Curtis (1831) and Duponchel (1834), the latter citing the 

 type. The type of Acalla, Hb., was fixed as Tortrix opththalmi- 

 cana, Hb. (a P&disca), by Stephens in 1834 (vide 111. IV. 141). 



The three following species differ from the type in having 3 and 

 4 of the fore wings stalked and 3 and 4 of the hind wings coin- 

 cident ; at present I am unwilling to separate them generically / M 

 from Oxygrapha. 



184. Oxygrapha negans, sp. n. 



Antenna; brownish. Palpi short, suberect, apical joint exposed, 

 second joint loosely clothed ; rusty brownish. Head rust-brown. 

 Thorax olive-grey with a greenish tinge. Fore wings olive-grey 

 with a greenish tinge, the costa shining pale bronzy-brown 

 throughout, the termen and cilia the same : an oblique series of 

 raised fuscous scales extends from the costa before the middle in 

 a slightly outwardly bowed line towards the middle of the dorsum ; 

 this is followed beyond the middle by ill-defined, scarcely visible, 

 parallel lines of pale brown (not iridescent, but appearing only in 

 certain lights). Exp. al. 16 mm. Hind wings trapezoidal ; umber- 

 brown, with a pale line along the base of the umber-brown cilia,
