Cleora plax sp. n. 



(Text-figs. 90-92 ; PL 8, figs. 287, 288 ; Map 4) 



o". Vestiture white, irrorate with drab and bister ; patagia edged with fuscous. Wings 

 white, lightly irrorate with bister ; broad snuff brown fascia proximad of antemedial fascia on 

 fore wing ; similar fascia distad of postmedial fascia on each wing ; cubital veins and remaining 

 veins distad of postmedial fascia on each wing interruptedly warm buff ; other markings fuscous 

 in holotype, (a very fresh specimen), bister in remainder of series (PI. 8, fig. 287). Underside of 

 wings white, suffused with fuscous (PI. 8, fig. 288). 



6*. Genitalia (Text-figs. 90, 91). Scobinate medial plate of gnathus shallow and broad, 

 equal in width to cucullus ; apex of sacculus truncate with short, digitate process inclined 

 towards mid-valve ; apex of aedeagus narrowly rounded and inclined to one side ; vesica with 

 two cornuti fused at base, one slightly sinuous with apical fourth dilate and spatulate and with 

 one side coarsely serrate and ventral surface scobinate, the whole about one-half as long as 

 aedeagus, the other tapered sharply apicad, one-sixth as long as aedeagus. 



$. Upperside of wings patterned similarly to that of male, but irroration, especially in basal 

 area of fore wing and medial area of each wing, greatly reduced. Fuscous pattern of underside 

 restricted to discal spots and terminal bands, narrow on hind wing. 



$. Genitalia (Text-fig. 92). Anterior margin of lamella postvaginalis sinuous and produced 

 medially ; colliculum slightly longer than broad, posterior margin sharply defined ; anterior 

 third of bursa copulatrix membranous, remainder sclerotized and ribbed with a shoulder-like 

 projection at one side of posterior margin. 



Measurements. 6* 40-41 mm. ; °. 46 mm. 



Similar externally to forms of thyris, tulbaghata and munda. Male genitalia 

 similar to those of nigrisparsalis and tulbaghata in structure of sacculus and similar 

 to tulbaghata in shape of cornuti ; the broad, shallow scobinate medial plate of the 

 gnathus is distinctive. In the female genitalia the posterior margin of the lamella 

 postvaginalis is diagnostic.
