A variable species developing forms comparable with those of acaciaria from 

 Reunion and transversaria from the Comoro Is. (PL 4, fig. 196). The male genitalia 

 of this and the following species, viettei from Sao Thome I., each has a markedly 

 dilate, membranous cucullus, a similarly stout uncus and a similarly shaped 

 gnathus ; whilst their affinity with each other is clear, their relationship with other 

 species in the genus is obscure. Because of the similarity of range of variation in 

 wing-pattern, the dilate cucullus and the well developed sacculus, tamsi and viettei 

 are placed after those species of the acaciaria group. 



It is with pleasure that I name this species after Mr. W. H. T. Tarns of this 

 department, in token acknowledgement of his frequent, kindly advice.

o* $. Externally similar in both sexes to the preceding species and displaying a similar 

 range of colour and wing pattern. 



o*. Genitalia (Text-figs. 28, 29). Cucullus almost circular and extending beyond ventral 

 margin of valve ; ventral margin of valve smooth and without process from sacculus ; broad- 

 based, curved and tapered process at mid-valve ; vesica with one tapered cornutus, one-half as 

 long as aedeagus. 



$. Genitalia (Text-fig. 30). Lamella postvaginalis produced and rounded medio-posteri- 

 orly ; lamella antevaginalis crenulate at each side ; colliculum slenderly produced at each side 

 posteriorly, tapered anteriorly ; anterior third of bursa copulatrix membranous, remainder 

 ribbed and very weakly sclerotized. 



Measurements. 6* 37 _ 43 mm. ; $ 39~43 mm. 



Closely related to the preceding species, tamsi, from which it may be distinguished 

 structurally ; in the male genitalia by the smooth ventral margin of the valve and 

 the absence of a process from the sacculus, by the broader-based and more slender 

 process at mid- valve and by the loss of the second, shorter cornutus on the vesica ; 

 in the female by the crenulate pattern of the lamella antevaginalis and the long 

 posteriorly produced and anteriorly tapered colliculum. 



Distribution (Map 9). Sao Thome I. ; probably endemic.
