84 D. S. FLETCHER 



<$ (PI. io2, fig. 914). Vestiture and wing pattern similar to those of pringlei, but wings 

 suffused with brown and brownish grey distad of the subterminal fascia. Male hind tibia 

 simple. 



^ genitalia (Text-figs no, in). Ventral margin of valve curved apicad; dorsal margin 

 slenderly sclerotized and irregularly scobinate in apical fourth; dorsal process dilate and setose 

 at one-fourth; hair-scales of coremata light buff. Aedeagus with a strongly sclerotized, 

 acicular projection extending almost to its tip and a short, thorn-like projection, both arising 

 at three-fourths. Fulcrum with a spine-like tip. Vesica with a tapered cornutus, one-half 

 as long as greatest width of aedeagus. 



$ unknown. 



Measurements. Fore wing: $ 16 mm. Antennal pectinations: $ 14 X diameter of shaft. 



The extent of the irregular scobination along the apical part of the dorsal margin 

 of the valve and the form of the projections on the aedeagus are specifically 

 diagnostic. 



Distribution. S.W. Uganda, Rwanda, Zaire. 



Material examined. 



Holotype $, Uganda; Ruwenzori, Bwamba Pass (west side), 5500-7500 ft, 

 xii. 1934-i. 1935 (F. W. Edwards), Geometridae genitalia slide no. 3304, in BMNH. 



Uganda: Kigezi, Mafuga Rain Forest, 7500-8000 ft, vi. 1961 (T. H. E. Jackson), 

 1 $; Kigezi, Kayonza, hi. 1967 (R. C. Otieno), 1 <$ (NMK, Nairobi); Kigezi, Impene- 

 trable Forest, hi. 1967 (R. C. Otieno), 1 <$ (BMNH). Rwanda: Kabira Forest, 

 12 miles N. of Usumbura, 7000 ft, ii. 1924 (T. A. Barns), 1 <$. Zaire ('Belgian 

 Congo'): Kalonge, 2210 m, 25-27.vii.1952, 1 <$ (MRHN, Brussels). 



Zamarada psectra sp. n. 



(Text-figs 112, 113; PI. 25, figs 551, 552) 



<$ genitalia (Text -figs 112, 113). Dorsal margin of valve slenderly sclerotized, apical third 

 irregularly scobinate, tip produced towards uncus; in some examples the scobinate area extends 

 to one-half dorsal margin ; dorsal process as in dentata ; coremata hair-scales light buff. Aedeagus 

 with a strongly sclerotized, acicular projection extending beyond its tip and a second, one-half 

 as long as the first, arising at three-fourths. Fulcrum with strongly sclerotized spine-like 

 apex. Vesica with a tapered cornutus equal in length to greatest width of aedeagus. 



$ genitalia (PI. 25, figs 551, 552). Sterigma with two digitate processes extending anteriorly, 

 one at each side, the longer extending into the corpus bursae the posterior two-ninths of which 

 are sclerotized. 



Measurements. Fore wing: <§ 15-17 mm; °- 15 mm. Antennal pectinations: £ 15 X, 

 $ 8 x diameter of shaft. 



Externally closely similar to dentata, which it appears to represent in the forests 

 of eastern Africa. Distinguished from it in the male genitalia by the more extensive 

 scobination of the dorsal margin of the valve, by the longer, acicular projections 

 from the aedeagus and by the longer cornutus on the vesica. The male hind tibia 

 is simple. The female of dentata is unknown. 



Distribution. Kenya, Tanzania, Mozambique, Rhodesia.
