1910.] FROM NORTHERN RHODESIA. 15 



The males of this species, of which I have taken over sixty in- 

 dividuals, all differ from the figure of the type by the possession 

 of a row of seven minute internervular marginal red spots on both 

 sides of the outer margins of the primaries, and by the absence of 

 white submarginal spots on the upperside of the secondaries. The 

 band on the primary is also pale golden, not whitish. 



Another specimen, however, which I have had an opportunity 

 of examining in the Tring Collection, from the same locality as the 

 type, viz. Bihe, Angola, agrees in the main with my specimens. 

 We must, therefore, conclude that the type specimen is a some- 

 what abnormal one. 



The females, which are somewhat variable, differ greatly from 

 the males, especially on the upper surface. 



2 . Upperside. — Primaries. Ground-colour pale golden, more 

 or less suffused towards base with dusky scales ; base of costa red 

 becoming orange towards apex ; a narrow black apex and a 

 narrow line of black on outer margin enclosing seven minute 

 internervular brick-red spots as in the male. A spot in middle 

 of cell and a well-marked discocellular spot ; immediately below 

 another spot in area 15. In some specimens there are also sub- 

 marginal spots in areas 3, 2, 1, of which that in 2 is placed near 

 the median nervure. 



Secondaries. Ground-colour as primaries with a well-defined 

 medium black margin, some of underside spots represented, 

 especially discocellular and four spots around end of cell. 



Underside. — Primaries as upperside but ground-colour some- 

 what more fulvous ; black apex reduced ; inner portion of apex 

 and whole of secondaries have the same shining golden ground- 

 colour as the male. Other markings of secondaries as in 

 male. 



Fringe of primary dusky, of secondary pale golden ; palpi 

 ochreous ; vertex and anterior portion of thorax bright red ; 

 abdomen, above, black marked laterally with a row of small red 

 spots, below, ochreous marked black and red in mid-ventral 

 line. 



The relationship of this peculiar species to other AcraainaB is of 

 considerable interest. In the first place, the rudiment of a third 

 internal nervule on the secondaries is well-marked for three- 

 quarters of its distal portion, only fading away as it reaches the 

 base. The somewhat long hairs which are placed upon all the 

 nervules on the under surface are also distinctly visible. The 

 general resemblance of the female of the above described species 

 to A. anacreon Trim, and its allies led me to examine them also. 

 I find this nervule to be well-marked in anacreon Trim., induna 

 Trim., bomba Grose-Smith, and wigginsi* JSTeave, and a distinct 

 trace of it in violarum Boisd. and its forms. This character seems 

 to be absent from all other Ethiopian or Oriental Acraeinae, though 

 traces of it frequently remain in the pattern usually as a paired
