OO. 
NEUROPTERA. 
RR. Tooth of tarsal claws as long as or longer than 
tip of claw itself, front wing with discoidal 
triangle free . . . . woe ee 
Hind wing with nodus midway between base and 
stigma; area between anal “angle” and proximal 
subbasal sector having the cells not parallel to that 
sector or to the margin, but arranged between four 
or more branches of that sector which meet the hind 
margin nearly at right angles. (Agrees with charac- 
ters given under P and Q for Dythemis.) . 
OOO. Hind wing with nodus nearer to base than to 
stigma, base notably widened, cells between the 
proximal subbasal sector (A; of C. & N.) and the 
rounded anal “angle” not arranged in rows parallel 
to both, nor as described for Paltothemis; with 
yellow, brown, or black colouring at base. 
S. Nodal sector not waved in its middle, hind wing 
with one submedian cross-vein, anterior lamina of 
male entire. 
T. Abdominal segment 4 with no additional* trans- 
verse carina, 8 and 2 with one each. 
U. Front wing with discoidal and internal triangles 
free, two post-triangular rows, only one row 
of postcostal cells out to level of submedian 
cross-vein ; front and hind wings with only 
one row of cells between principal sector and 
supplementary sector next below proximal 
to level of stigma, which latter has but one 
cross-vein below it; vulvar lamina of female 
one-fifth or less as long as segment 9 
UU. Front wing with discoidal and internal tri- 
angles cross-veined, three post-triangular rows, 
postcostal cells increasing to two rows proximal 
to level of submedian cross-vein; front and hind 
wings with two rows of cells in part of area 
between principal sector and supplementary 
sector next below proximal to level of stigma, 
which latter has two or three cross-veins below 
it; vulvar lamina of female very short, one- 
eighth to one-tenth as long as segment 9 
TT. Abdominal segments 4, 3, and 2 each with one 
additional transverse carina; front wing with 
MacrorTHEMIS. 
PaLToTHEMIS.

TAURIPHILA.
