1897.] WEST-INDIAN MICEO-LEPIDOPTEEA. 131 



Type, $ Mus. Hedemann. 



Hah. West Indies — St. Thomas, 9 III. {Hedemann). Unique. 



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

 Ot/clia, 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 Peroncm, Poli, 1795. Oxigrajjilia, Hb. (corrected to 

 Oxygrapha by Wilkinson), was monotypical from its publication, 

 and should therefore be chosen in preference to any other name 

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

 synonymous with Bhacodia, 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 Torfrix optlitlialmi- 

 cana, Hb. (a Pcedisca), 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 

 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 obhque series of 

 raised fuscous scales extends from the costa before the midcUe in 

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

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

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

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

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