suggests that they do. In view of the overlap in occurrence (although the habitats 

 are unknown) and, because of considerable differences in the genitalia, this whole 

 group is treated as a species-complex and three new species are described. The 

 basic pattern of the male genitalia is similar in all the species of this complex. Few 

 females are known and all are from the range of strigifera and are indistinguishable 

 from one another and are therefore attributed to that species.

Striglina ferula sp. n. 



(PI. 8, fig. 32; PI. 31, fig. 167; Text-fig. n) 



o*. Wing, i3*5-i5 mm. Head, thorax etc., as in S. strigifera. Wing pattern as in PL 8, 

 fig. 32. Fore wing with vein i? 4 and R s stalked. R t widely separated from R 3 ; R 2 and R s 

 running close together for part of length. lA and 2A join near base. Hind wing with Sc+R 1 

 and Rs fused for a short distance near base. 



Genitalia <$ (PI. 31, fig. 167). Uncus with two long lateral spines with small tufts of hair 

 at base and with small spine on each side of mid-line. Lateral finger-like process with hairs. 

 Gnathus as in strigifera. Apical process of valve strongly reflexed with prominent spines. 

 Costal process at base of valve elongate with hairs. Juxta with slender lateral arms. VHIth 

 sternite of abdomen with sclerotized plate, posterior margin as in Text-fig. 11. Aedeagus with 

 two prominent patches of cornuti. 



$. Unknown. 



Discussion. Externally similar to strigifera but usually darker in colour. S. 

 ferula can be separated from the other species in the group by the shape of the apical 

 process of the valve, the presence of two smaller spines on the uncus and the shape 

 of the costal process of the valve. Only a few specimens have been examined but 

 these tend to be larger than specimens of strigifera.
