REVISION OF GENUS ZAMARADA 117 



distinctly ringed discal spots. Differs markedly on the underside of the wings in the 

 reduction of the dark brown of the non-hyaline terminal area to a slender shade bordering 

 the hyaline area on the fore wing between the costa and vein M 3 and between vein Cu lb and 

 the posterior margin; the remainder of the non-hyaline area of the wings is pale yellowish 

 brown. 



<J genitalia (Text-figs 187, 188). Differ from those of dentigera in the presence of a serrate 

 ridge along the apical fourth of the dorsal margin of the valve, in the bifurcate form of the 

 projection at two-thirds aedeagus, arising nearer base than in dentigera, and in the almost 

 simple fulcrum. 



9 genitalia (PI. 38, figs 603, 60 j). Distinguished from dentigera by the more extensively 

 sclerotized corpus bursae.

Three specimens from coastal forests of Kenya are associated with chrysopa, 

 but excluded from the type-series. A specimen from Nyali is more broadly and 

 darkly marked with vinaceous grey immediately distad of the hyaline area than 

 in the typical pair; structurally it is identical with the holotype. 



Two specimens from Sokoke Forest, 8 miles south of Malindi, are smaller, having 

 a fore wing length of 13 mm and have minute, uniformly dark discal spots. In 

 the genitalia of one example the projection from two-thirds aedeagus, bifurcate 

 in the holotype and in the Nyali specimen, is truncate and in the other specimen 

 tapered and blade-like. 



The larva of the reared specimen from Sokoke Forest was found on the foliage 

 of Ochna sp. (Ochnaceae), but pupated without feeding further; Ochna may not 

 be the host-plant.

Zamarada fibulata sp. n. 



(Text-figs 189, 190; PI. 39, figs 605, 606; PI. 106, fig. 953) 



(J 9 (PI- IO °. n g- 953)- Hyaline area of wings green-tinged, sparsely irrorate with brown 

 and finely edged distally with yellow and dark brown. Non-hyaline terminal area light 

 brown (pi. 6, D5) irrorate with a darker shade of brown (pi. 6, E5) ; dentate subterminal fascia 

 strongly marked, a darker shade of brown, finely edged distally with buff. Underside of 

 non-hyaline terminal area of wings uniformly dark brown. 



<J genitalia (Text-figs 189, 190). Aedeagus tapered with a thorn-like projection at two- 

 thirds. Fulcrum broadened asymmetrically apicad, extending beyond and enfolding tip of 

 aedeagus; apex with two unequal projections, each with a short, thorn-like tip. 



9 genitalia (PI. 39, figs 605, 606). Sterigma complex with two asymmetrical projections, 

 serrate-edged on their apical margins, extending posteriorly ventrad of a sclerotized plate, 

 the posterior margin of which is scalloped and serrate.
