Allied to " Hypenodes " jucundaJis of Snellen (Tijd. voor 

 Ent. 1886, pi. V. fig. 10) • but I do not see how it differs 

 from Ecjnasia, and it certainly has little in common with 

 Hypenodes.

Allied to B. atrotumens * : primaries above pearl-grey, 

 suffused towards base and on costal area towards apex with 

 brownish ; a broad oblique white belt from costa before the

 apical third of outer margin, whence to apex it becomes very 

 narrow and obscure ; the projecting patch of scales just be- 

 yond the middle of inner margin elliptical, blue-grey and 

 black spangled with silver ; a few scattered silver scales on 

 basal area and others indicating the ordinary position of the 

 discoidal spots, a few bounduig a brownish costal patch im- 

 mediately beyond the white belt ; a silver stripe forming the 

 inner boundary of the bi'ownish apical patch ; a brighter 

 silver lunulated marginal stripe ; fringe grey ; subapical

OjJercularia jjarallela. 



Body slender, about three times as long as broad ; sides 

 parallel for about two thirds of their length from the margin,

 Epizeuxis\ by Snellen (Tijd. voor Ent. 1879, p. 130, pi. vii. fig. 1).
