P. tibialis, Pict. 
P, tibialis, Pict., Perlides, 217, pl. 18, figs. 6, 7. 
This species may be briefly described as having a black 
head and thorax, bright yellow abdomen, yellow wings, 
and black legs with yellow tibiz. Specimens in De Selys’ 
collection and my own agree perfectly with Pictet’s de- 
scription, and with the dimension for the length of body, 
but only expand to 35 instead of 45 mm., and all are 
females. 
Perla tinctipennis, sp. nov. 
Head black in the middle, yellow anteriorly and pos- 
teriorly. Pronotum slightly narrower than the head (with 
the eyes), broader than long, slightly broader anteriorly ; 
the sides straight, with sharp angles, blackish-fuscous 
with a narrow median impressed yellowish line, the disk 
coarsely rugose ; meso-notum blackish, with yellow spots ; 
abdomen dull ochreous (the whole under surface of the 
body pale ochreous); tails yellow; egg-valve very narrow, 
with a triangular excision in the middle ; ; legs yellow, the 
tibiz and apex of femora blackish-fuscous ; wings long, 
pale olivaceous or yellowish, with the costal margin 
more strongly coloured; neuration yellow, the transverse - 
nodal nervure somewhat fuscous and clouded ( ¢ ). 
Length of body (without the tails) 21 mm.; expanse 
70mm. One of the largest known species, with some- 
what the colours of P. tibialis. 
Yokohama (Pryer). One ¢ in Wormald’s collection.
