sluggish, and they appear to be rather restricted in distribution, 

 and not generally plentiful. 



The six species known to me may be analytically arranged as 

 follows : 



A. Thorax white ..2. magnana. 



B. Thorax whitish mixed with dark scales. 



1 . Forewings white, transversely strigulated 



with grey 1. canana. 



2. Forewings whitish, densely irrorated with 



grey. 



a. Forewings elongate ; veins 6 and 7 of 



hindwings stalked .. .. ..6. signigerana. 



b. Forewings short and broad .. . .4. passalotana. 



C. Thorax greyish-ochreous .. .. ..5. lignigerana. 



D. Thorax dark fuscous .. .. .. ..3. dolosana. 



1. Acrop. canana, Wall:. 



(Tortrix canana, Walk., Brit. Mus. Cat. 331.) 



$ (?). about 11". Head and thorax whitish, irrorated with 

 grey. Forewings white, with numerous slender irregular 

 transverse fuscous-grey strigulae ; outer edge of basal patch 

 represented by an oblique blackish transverse line about one-fifth 

 rather angulated in middle, apex of angulation connected with a 

 short longitudinal blackish line in disc below middle ; 'central 

 fascia represented by a grey black-margined spot on costa before 

 middle, and a grey oblique streak on inner margin about two- 

 thirds, not reaching half across wing ; beyond these is a small 

 grey blotch in disc above middle, margined beneath by a short 

 black longitudinal line ; a grey triangular blotch on costa towards 

 apex, its apex expanded into a small irregular spot reaching 

 half across wing, and black-margined ; an elongate cloudy-grey
