REVISION OF GENUS ZAMARADA 137 



a transverse band, broadened laterally and often ornamented with spine-like 

 projections, symmetrical or asymmetrical. 

 Distributed south of about 9 S. latitude. 



Key to Species 



1 Distal margin of hyaline area of wings evenly crenulate or dentate, not bowed 



distad between veins M 3 and Cw lb . Non-hyaline terminal area of fore wing 

 not wider than 1-5 mm at and posterior of vein M 3 . Apical half of uncus 

 laterally compressed ; dorsal- ventral depth equals one-half of greatest width 

 of aedeagus ........ angustimargo (p. 142) 



- Distal margin of hyaline area of wings bowed distad between veins M 3 and 



Cu lb . Non-hyaline terminal area of fore wing more than 2 mm wide at 



and posterior of vein M 3 . Uncus not so formed .... 2 



2 (1) Margins of both valves smooth; left valve with broad-based, tapered process 



in middle of apical third ........ psi (p. [42) 



- Apical margin of each valve with one or more short, thorn-like projections 3 



3 (2) Apical margin of each valve with one thorn-like projection ... 4 



- Left valve with two thorn-like or angular projections from, or from near, 



apex 5 



4 (3) Apical projections symmetrical; dorsal process with shoit, setose, digitate 



projection at one-third ...... aequilumata (p. 140) 



- Apical projections asymmetrical; base of projection on right valve extended 



basad along middle of valve in form of slender, sclerotized ridge; dorsal 

 process setose in basal third, but no digitate projection developed 



bathyscaphes (p. 137) 



5 (3) Apex of dorsal margin of each valve rounded. Left valve with angular 



projection in apical fourth, near dorsal margin . . odontophora (p. 139) 



Apex of dorsal margin of each valve produced in thorn-like form . . 6 



6 (5) Left valve with a sclerotized ridge just below thorn-like extension of dorsal 



margin ......... adiposata (p. 139) 



- Left valve without sclerotized ridge below thorn-like extension of dorsal 



margin .......... aclea (p. 141)

(J$ (PI. 109, fig. 974). Hyaline area of wings, extending to termen along vein C« la , greyish 

 yellow, slenderly edged distally with black; discal spots grey. Small area at base and non- 

 hyaline terminal area of each wing variable in colour, ranging from brownish orange (pi. 6, C6, 

 caramel-brown) to light brown (pi. 6, D4, camel) ; dentate subterminal fascia weakly marked 

 in a shade darker than the ground colour and slenderly edged distally with light yellow; cilia 

 chequered light brown and light yellow. Underside of non-hyaline terminal area varying 

 in colour, being comparable with that of the upperside.
