72 P. E. S. WHALLEY 



$. Wing, 14 mm. Colour and pattern as male. Larger and more reddish brown than 

 nominate subspecies. The female can be separated from c. declivita by the shape of the ostium, 

 the sclerotized edges are serrate or wavy in c. amani and c. clathrata but smooth in c. declivita. 



Genitalia $. As nominate subspecies. 



Discussion. This subspecies is the most easterly of the group. It is interesting 

 that it has differentiated only in size and colour from the nominate one and not 

 differentiated in genitalia as has the Kenyan species. C. amani occurs in a wet 

 region similar to the nominate subspecies whereas the Kenyan subspecies occurs in a 

 drier zone.

Striglina clathrata declivita ssp. n. 



(PI. i, O; PL 30, fig. 164, PL 53, fig. 309) 



<£. Wing, io-5-i4'5 mm. Morphologically similar to the nominate subspecies, larger, and 

 with differences in the genitalia. 



Genitalia <$ (PI. 30, fig. 164). As nominate subspecies but uncus with more rounded sides 

 and shallower median incision. Process on base of valve shorter and broader than nominate 

 subspecies and juxta smoother in outline, without median thickening. 



9- Wing, 14-14-5 mm. As nominate subspecies but larger and with differences in the shape 

 of the ostium. 



Genitalia $ (PI. 53, fig. 309). As nominate subspecies but with smooth edge to the sclerotized 

 ostium. 



Discussion. At present this subspecies is known only from one region of Kenya. 

 For separation see under the other two subspecies. Since the Kenyan species is 

 only known from one locality on the edge of the range of the nominate subspecies I 

 am regarding it as a subspecies in spite of some morphological differentiation in the 

 genitalia. This subspecies occurs in a drier locality than the other two subspecies 

 but no information on the biology is available.
