Cleora nigrisparsalis (Janse) comb. n. 

 (Text-figs. 84-86 ; PL 8, figs. 281-286 ; Map 4) 



Neocleora nigrisparsalis Janse, 1932 : 270, pi. 8 : 5 ; fig. 100. 



(J. Vestiture white, irrorate with fuscous black, lightly on first abdominal segment. Wings 

 white, densely irrorate and patterned with fuscous black (PL 8, fig. 281). Underside of wings 

 white, patterned with fuscous black (PL 8, fig. 282). 



o*. Genitalia (Text-figs. 84, 85). Scobinate medial plate of gnathus semicircular, equal in 

 diameter to two-fifths width of cucullus ; a small spatulate, digitate process from apex of 

 sacculus ; vesica with two cornuti fused at base, one of even width, apex serrate at one side, 

 dorsal and ventral surfaces scobinate apically, one-half as long as aedeagus, the other tapered 

 sharply apicad and one-seventh as long as aedeagus. 



$. Similar in pattern to male ; upperside of wings less heavily, but more evenly irrorate 

 with fuscous black (PL 8, figs. 283, 284). 



$. Genitalia (Text-fig. 86). Anterior margin of lamella postvaginalis irregularly shaped ; 

 colliculum one and one-quarter times as long as greatest width, slightly broadened posteriorly, 

 posterior margin sharply defined ; anterior three-sevenths of bursa copulatrix membranous, 

 remainder sclerotized and ribbed with a shoulder-like projection at one side of posterior margin. 



Measurements. $ 4 0_ 44 mm. ; $ 41-52 mm. 



The range of variation in colour and pattern in nigrisparsalis is similar to that 

 found in both thyris and tulbaghata ; the similar forms in each species are virtually 

 indistinguishable except by genitalia. Typical forms of nigrisparsalis (PL 8, figs. 

 281-284) are recognisable externally by the dense fuscous black irroration of the 

 upperside of the wings and by the sharply contrasted and well-defined fuscous black 

 and white pattern of the underside. Structurally the small digitate process on the 

 sacculus and the shape and proportions of the cornuti on the vesica in the male 

 genitalia and the shape of the sterigma, the sharply defined posterior margin of the
