On Jan. 11, 1913, Dr. G. B. Longstaff captured at a height 
of about 1,000 ft., between Curatici and Zigzag, Venezuela, 
five individuals, two males and three females, all of which 
belong to this section of the genus Pieris. I have no doubt 
that the two males are Felder’s P. sevata. They answer 
perfectly to the description, and correspond closely with the 
Kaden ¢ in the British Museum. With regard to the females 
I do not feel so certain, but I think that at least one of them, 
that numbered by Dr. Longstaff 451, is the female of P. sevata. 
The female numbered 433 is more problematical. It corre- 
sponds well in size and shape with P. sevata, but is strikingly 
deficient in the dark markings of the upper surface. The 
scent-scales of Dr. Longstafi’s two males are like those 
of P. diana, being of about the same length, but slightly 
narrower. 
On March 29, 1907, Dr. Longstaff took in the same locality 
as the preceding a male Pieris, which is well figured on Plate 
III, figs. 1, 2, of his book entitled ‘* Butterfly Hunting in 
Many Lands.” On page 320 of the same work he mentions 
the circumstances of its capture, and cites my opinion that 
it is ‘‘ near P. sevata, Feld., and appears to be identical with 
three specimens from Venezuela placed in the National 
Collection under P. sincera, Weymer, but which might well 
be considered as a distinct species, or at any rate local race.” 
These three specimens are those referred to above, p. exii. 
I have no doubt whatever that Dr. Longstaff’s specimen 
(numbered 1927) is quite distinct from P. sevata as represented 
by the two males captured on Jan. 11, 1913. It is smaller, 
differs somewhat in shape, and has a well-marked dark spot 
at the end of the cell on the underside of the hind-wing, the 
males referred to P. sevata being immaculate beneath. All these 
points are such as might characterise seasonal phases of the 
same species, but what really differentiates the present form 
from the authentic P. sevata is the distribution and character 
of the scent-scales. In P. sevata 3, the mealy streaks formed 
by the scent-scales on the upper surface of the fore-wing fuse 
along the inner or posterior side of the median vein between 
the internal vein and the first median branch; in the present 
species there is no such fusion, and the clear area of the
