A REVISION OF THE ETHIOPIAN DREPANIDAE (LEPIDOPTERA) n 



which have heavily sclerotized, curved, basal spines ; the curious pouch-like 

 diaphragma which extends anteriorly over the saccus ; and the eighth sternum 

 which has more slender apodemes than in strandi and shorter posterior arms. The 

 remaining group, seydeli, possesses peculiar invaginate sacs in the uncus, an almost 

 flat diaphragma, thickly setose valves, a truncate saccus, a distinctively shaped 

 aedeagus, and a most unusual, asymmetric arrangement of sclerites in the eighth 

 sternal region and in the membrane between this and the ninth sternum. 



The groups strandi and erosa can also be separated by the shape of the signum in 

 the female genitalia. The signum is a small, spinose, bilobed patch in strandi, 

 whereas in erosa it is an elongate, folded band, tapered at each end. There is a 

 single female from Fernando Po (see page 45), which I can only tentatively identify 

 as a specimen of the species lumaria, in which the signum resembles that in the 

 species-group strandi.
