female genitalia by distinct differences (Text-figs. 180, 182-184) • The male possesses a third pair 

 of vincular processes not found in either subviridis or pianola. 



Measurements. A.P.R. : <J. 15 ; $. 9. Wing : <$. 12-5, 12-0-130 mm. (3) ; ?. 16-5, 

 15-5-18-5 mm. (5). 



Discussion. There are close affinities between this species and subviridis and 

 pianola, but these are not as close as those between the latter two species. 



The extent of individual variation in coloration and colour-pattern is similar to 

 that described for subviridis. One of the more interesting forms is represented by a 

 male from Nigeria in which there is a dark brown streak in the cell and another 

 below the areole as in the holotype of pianola. 



Gaede (1931 : 51, 52) catalogued this species under both Spidia and Phalacrothyris 

 in the same publication. 



Distribution (Map 5). Nigeria and Cameroun. A male from Gabon and a 

 female from Fernando Po, both in the British Museum (Natural History), probably 

 belong to this species, but further material is needed before this can be confirmed.

Diagnosis. <J. Shape and colour-pattern of wings probably similar to excentrica and 

 pianola (see Discussion), o* genitalia (Text-figs. 185-187) : vinculum with two pairs of long, 

 heavily sclerotized processes ; medial process of vinculum long and acuminate ; aedeagus with 

 conspicuous lateral lobe ; eighth tergite as in excentrica ; (eighth sternite probably accidentally 

 folded at its posterior margin on holotype slide, as in Text-fig. 185). 



Measurements. A.P.R. : Not known. Wing : 0*. Given as "25 mm." in the original 

 description. It is obvious from the illustrations given by Holland that this measurement is the 

 distance between fore wing apices. 



Discussion. Owing to the variability in the coloration and in the size and 

 number of the hyaline patches on the wings it is doubtful whether an examination 

 of the holotype, the only known specimen, would have revealed any significant 

 external difference between miserrima and the similarly patterned excentrica or 

 pianola. The genitalia slide of the holotype has, however, been examined and 

 compared with slides of excentrica with which miserrima has close affinities. The 

 differently shaped vincular processes in the male genitalia (probably slightly dis- 

 placed in the type-slide of miserrima and consequently in Text-fig. 187), the differ- 

 ently shaped valve, and the large lateral lobe on the aedeagus distinguish miserrima 

 from excentrica.
