Gonoreta forcipulata sp. n. 



(Text-figs. 134-137 i PI- 7. fi g- 295 ; Map 4) 



Description. q". $. Palp scarlet. Head scarlet immediately above labrum becoming darker 

 dorsally except at base of antenna. Dorsal surface of antennal shaft and dorso-posterior margin 

 of head buff. 



Dorsal surface of thorax nearly white anteriorly ; remainder greyish white, each scale whitish 

 with dark band near apex. Ventral surface of thorax pale buff except for region surrounding 

 eyes which is buff above eyes and scarlet lateral to and below eyes. Front surface of prothoracic 

 leg scarlet, rest of leg buff ; other legs with some scarlet scales on front surface. 



Wing shape and colour-pattern as in Plate 7, fig. 295. Ground-colour of upper surface of fore 

 wing pale grey, with reddish brown medial shade and dark brown speckling and striations ; 

 subterminal markings very dark brown near tornus ; fringe dark brown. Upper surface of hind 

 wing pale pinkish brown proximally, becoming darker distally ; fringe light reddish brown with 

 dark brown outer edge ; trace of medial shade in some specimens (e.g. Plate 7, fig. 295) but not in 

 holotype. Under surface of both wings orange (holotype), reddish orange or orange-buff, 

 sometimes suffused with grey on fore wing (holotype), usually slightly paler at base of hind 

 wing ; both wings speckled and striate with grey ; grey postmedial fascia present on fore wing, 

 nearly straight posteriorly but turned sharply inwards away from apex near costal margin of 

 wing. 



o* genitalia as in Text-figs. 135-137. The forcipulate posterior processes of the eighth 

 sternum are particularly characteristic. 



$ genitalia with unusual, slightly concave plate immediately anterior to ostium (Text-fig. 



134)- 



Measurements. A.P.R. : q*. 9 ; $. 8. Wing : 5*. 18-0, 17-0-18-5 mm. (3) ; $. 19-0, 

 18-0-19-5 mm. (2). 



Discussion. The colour-pattern and coloration is similar to that of both differ en- 

 ciata and contracta but the three species can be readily distinguished by the male and 

 female genitalia. The closest relative of forcipulata is probably angulosa, but the 

 greyer coloration and the shape of the hind wing make separation of the two species 

 a simple matter without the use of genitalic characters. 



The ground-colour of both surfaces of the wings is subject to considerable indi- 

 vidual variation : it may be one of many shades of mainly pinkish grey on the upper 

 surface of the fore wing, and on the hind wing one of a similiar range of colours in- 

 cluding darker tones than on the fore wing. The degree of speckling or striation 

 also varies. 



Distribution (Map 4). Congo, Northern Rhodesia and Uganda.
