(. ex -) 
is given by Godart simply as “ Brazil.” It is nearly allied to 
the two preceding species, but easily distinguishable from 
them by the parallel dark markings on the underside of the 
hind-wing, which are specially interesting as affording material 
for an incipient mimetic pattern. The posterior of the two 
bands is clearly homologous with the dark spots at the end 
of the cell in P. buniae and P. ausia. The scent-scales of 
P. phaloe are very much like those of P. buniae and P. ausia 
in size and shape, but can usually be distinguished by the 
attenuated distal portion, of which the sides are parallel 
instead of tapermg. As in P. ausia the scent-scales tend to 
be somewhat narrower than in P. bumae. 
The three preceding species are, I think, all very closely 
related. The next species to be mentioned, though certainly 
belonging to the same section of Pzeris, stands a little apart 
from the first three. This is the form described by Felder 
from the Bogota district as P. diana. It is not unlike P. 
buniae in general appearance, but has the dark apex of the 
fore-wing generally narrower. It also differs in shape from 
that insect, the apex being more pointed, the hind border of 
the fore-wing being slightly concave, and the anal angle of the 
hind-wing somewhat prolonged. The scent-scales, though of 
the same elongated kite-like character as those of the three 
preceding species, are considerably shorter. 
Closely allied to P. diana is P. sevata, described by Felder 
from Venezuela. As to this form there is some degree of doubt. 
There is a specimen (¢) in the Collection of the British Museum 
which is presumably a co-type. It came through Messrs. 
Godman and Salvin from the Kaden Collection, and bears on a 
manuscript label “ sevata, Mz.” (7. e. Moritz) and the locality 
note “‘ Venez.” (Venezuela). No female specimen is assigned 
to P. sevata in the British Museum Collection, but there is 
another Kaden Pieris from the Godman-Salvin series which, 
though unplaced as such, must I think be a female sevata. 
It corresponds well with the description of the female given 
by Felder. Under the subspecific heading P. sincera, Weym., 
are two males and a female from Venezuela which bear on pin 
labels ‘‘ P. sevata, Felder.’’ These I am inclined to refer, not 
to P. sevata, but to another species to be mentioned shortly.
