the Rhopalocera of the Dollman Collection. = 257 
in Katanga by Neave. It is readily separable from the 
other species by its larger size and more conspicuous 
markings. It has a bronzy appearance which separates 
it readily from LE. djaelaelae. It might perhaps be taken 
at first for a large form of #. lugens. Its genitalia, however, 
are totally unlike those of any of the other species in the 
genus, the chitinous structures which form the so-called 
‘* penis-funnel,” through which the penis moves, in addition 
to furnishing upper and lower paired lateral projections, 
are produced ventrally to form a single long tapering 
chitinous process, which extends almost beyond the claspers 
and throughout is densely covered with short stiff spines. 
22. Parnara nyassae Hew. 
(Plate VII, figs. 15 and 16.) 
13 3g, 5 29, iv., Kashitu and Solwezi, showing consider- 
able variation in the coloration of the underside. Hewit- 
son’s type of this species, a female, has the hind-wing and the 
apex of fore-wing below of a violet-grey, and thus agrees 
exactly with roncilgonis Plétz, as shown by copies of his 
unpublished plate No. 1380 in B.M. The majority of 
Dollman’s specimens have this violet-grey replaced by 
yellow-ochre, and the costa and cell of hind-wing also 
marked with streaks of bright red; with this is usually 
correlated an increase in the yellow markings of the upper- 
side, particularly between the veins in costal and apical 
region of fore-wing. So distinct is this form that Dollman 
regarded it as a distinct species. The two forms certainly 
occur together in spite of the apparently seasonal character 
of their differences, though their genitalia do not seem 
to warrant their separation except as forms of the 
same species. In this case the light form may be called 
ennuari f. nov. (B.M. Types No. 076, 3, 077, 9, Solwezi, 
iv. 1918). Intermediates occur, but are scarce, one having 
been described, as far as can be ascertained without refer- 
ence to the type, by Karsch (B. E. Z., 38, p. 250, 1893) under 
the name of cojo Karsch. 
B. netopha Hew., which is frequently confused with this 
species, is really easily to be separated, as it has all the spots 
on the underside of the hind-wing crowded together towards 
the centre—nyassae has them in a wide circle. It only 
occurs from W. Coast to Uganda, as shown by the series in 
B.M. Hewitson’s type is a female from “ W. Africa.”
