22 D. S. FLETCHER 



The holotype of funesta collected by G. F. Leigh at Durban and another male 

 with identical data each has a wing-span of 35 mm. ; these may represent a dry 

 season form, or if reared, as much of Leigh's material is, they may be starvlings. 



Biology. A pupa was found on Pinus patula in Malawi. 



Distribution (Map 1). Malawi ; Rhodesia ; Transvaal ; Natal ; Cape Province. 



Material examined. Types. Of the two male syntypes of Chogada betularia 

 labelled " S. Africa ", I select as LECTOTYPE the specimen from which the 

 genitalia slide Geometridae No. 2143 has been made ; the paralectotype was 

 labelled by Warren " Chogada betularia Warren, Type <$ ", but is without abdomen.

Cleora flavivenata sp. n. 



(Text-figs. 13-15 ; PI. 3, figs. 176-179 ; Map 1) 



o*. Crest on first abdominal segment white ; remainder of vestiture white, irrorate with 

 drab grey and fuscous black. Upper surface of wings white, irrorate with drab grey and fuscous 

 black ; transverse fasciae and lateral streak in discal fold of fore wing fuscous black, slender and 

 sharply defined ; broad cinnamon brown to russet bands proximad of antemedial fascia on 

 fore wing and distad of postmedial fascia on each wing ; veins, except subcostal vein of fore 

 wing, streaked with ochraceous buff (PI. 3, fig. 176). Under surface of wings tilleul buff, 

 irregularly suffused and patterned with fuscous (PI. 3, fig. 177). 



o*. Genitalia (Text-figs. 13, 14). Arm of sacculus arcuate and finely tapered and, except for 

 tip, covered by a setose, membranous fold from the ventral margin of the valve ; aedeagus six 

 and one-half times as long as mean width and one and one-half times as long as dorsal margin of 

 valve, with broadly rounded apex ; vesica with two tapered cornuti, each slightly less than one- 

 third as long as aedeagus. 



$. Similar to male, but drab grey and fuscous black irroration sparse, except in distal third 

 of each wing ; cinnamon brown to russet bands narrower ; in some examples veins less strongly 

 streaked with ochraceous buff (PI. 3, fig. 178). Under surface of wings usually less suffused with 

 fuscous proximally (PI. 3, fig. 179). 



$. Genitalia (Text-fig. 15). Sterigma sclerotized as in figure ; bursa copulatrix pyriform 

 with slight projection medio-laterally ; anterior two-thirds membranous, remainder weakly 

 ribbed and weakly sclerotized. 



Measurements : $ 40-45 mm. ; $ 46-50 mm. 



The series from Kirstenbosch and Cape Town displays very little variation in 

 colour and pattern, except in the degree of dark irroration of the upper surface of
