A REVISION OF THE ETHIOPIAN DREPANIDAE (LEPIDOPTERA) 103 



Discussion. Close similarities in the male genitalia suggest that this species is 

 most closely related to fenestrata and goniata although it is readily separable from 

 them by the shape of the fore wing, the presence of a large orange-brown spot on the 

 hind wing and by the lamellate antennae. 



Distribution (Map 5). Known only from Cameroun and the Central African 

 Republic. 



Material examined. Type. Holotype $, Cameroun, Bitje, Ja River, 2,000 ft. 

 (Bates) ; Drepanidae genitalia slide No. 1187 ; in the British Museum (Natural 

 History).

Spidia inangulata sp. n. 



(Text-figs. 167-171 ; PL 9, fig. 306 ; Map 5) 



Description. q\ Head brown anterior to antenna] bases, bull posteriorly. Palp brown on 

 upper ami outer surface ; remainder buff. Antenna unipectinate ; upper surface buff . 



Thorax pinkish buff dorsally ; ventral surface pale buff, but darker around eyes Outer 

 surface of femur, tibia and proximal part of tarsus of fore leg orange-scarlet, but with medial part 

 of tibia orange. Shape of wings as in Plate Q, fig. 306 ; venation as for fenestrata Butler (Text- 

 fig. 153). Ground-colour of upper surface of fore wing buff (holotype), reddish buff or grey ; 

 lightly speckled with dark brown especially in costal area, at apex and near tornus ; medial shade 

 usually present, reddish buff (holotype), brown or grey ; brown oblique postmedial fascia, well 

 marked and reddish brown in holotype, poorly defined in half of examples examined, trace of 

 broad dentate subterminal fascia. Hyaline patches greenish, iridescent ; similarly coloured dis- 

 cocellular spot, spot in middle of cell and dark spot just (listed to anterior angle of cell (confluent 

 with spot at posterior angle of cell in some specimens, not holotype). One specimen examined 

 (not holotype) with two small hyaline spots instead of one large patch between Cu Ul and Cu lb . 

 Upper surface of hind wing often (including holotype) slightly darker than lore wing : varying 

 shades of brown, reddish brown (holotype) or greyish brown, lightly speckled with darker brown 

 (holotype) or greyish brown, lightly speckled with darker brown especially at outer angle. Very 

 dark brown discocellular spot and larger spot at posterior angle of cell ; broad antemedial fasi ia 

 continuous with, and same colour as, postmedial fascia of fore wing. Under surface of both 

 wings pale pinkish buff, speckled with very dark brownish grey ; fore wing with dark discocellular 

 spot, mid-cell spot, and dark-edged hyaline patches ; hind wing with large, very dark, brownish 

 grey, discocellular spot and trace of posterior cell-spot. 



o" genitalia as in Text-figs. 167-169. Vincular and valve processes bifurcate, medial part of 

 gnathus and juxta all particularly heavily sclerotized. Vincular processes not identically paired. 

 Base of aedeagus broad, truncate. 



$. Similar to male but with shorter antennal pectinations and more strongly produced fore 

 wing apex. Wings of all examined specimens with pale grey or greyish buff ground-colour on 

 upper surface and paler, but pinkish, under surface. 



$ genitalia as in Text-figs. 1 70-171. 



Measurements. A.P.R. : 6*. 7 ; $. 4. Wing : <$. 220, 20-0-230 mm. (15) ; $. 24-0, 

 23-5-25-0 mm. (3). 



Discussion. This species is very closely related to smithi Warren, but the 

 differently shaped hind wing makes separation of the two species a simple matter.
