are the tibiae themselves ; spines on the inner side of the tarsi, tarsi ending in a 
rather long claw; femora and tibiae of all legs with long dense hairs; mid tibia 
with two spurs, hind tibia with four spurs; spurs rather short and stout, 
covered with appressed hairs and scale-like hairs, and ending in a somewhat 
inwardly curved naked point which is provided with two rows of teeth (this- 
curved point is rather long in aurifodinae ) . 
Fore wing rather broad, sub-triangular, costa nearly straight, apex rounded, 
outer margin erect, straight, slightly sinuate, tornus rounded, inner margin 
nearly straight and without tufts; 1 b forked at base; 2 from frd lower median;. 
3 from fth 2 to 4; 4 well curved and from lower angle; 5 from middle of disco- 
cellulars; discocellulars erect and curved; 6 from middle of areole, which is 
long and narrow, nearly half length of vein 10, in some species ( simplex ) 
longer 1 ; 7 from before end of areole; 8, 9, 10 stalked, or 8, 9 stalked, and io* 
from the areole; 8 from 9 at frd of 9; 10 from stalk of 8, 9 beyond half of 10,. 
which originates near upper angle, thus making the areole very narrow; 11 
from frd upper median; 12 parallel to costa. 
Hind wing broad, triangular, costa somewhat curved, apex well rounded 
towards vein 7, outer margin well arched, slightly sinuate, tornus well rounded, 
inner margin somewhat arched ; 1 b curved ; 2 from j ust beyond f of lower 
median ; 3 from near lower angle ; -4 from lower angle ; 5 from above f of disco- 
cellulars, which are inwardly oblique; 6 and 7 on a stalk of over frd of 6 
and from upper angle; 8 parallel with, and approximated to, upper median 
for nearly whole length of median vein; no bar in tricolor, but some species- 
show an indication of it. 
Seven species have been placed in this genus, from which I remove spurcata y 
which I place in the genus Zana, and I think aurifodinae should be placed here,, 
and So should encausta. 
I have not been able to secure the description of Walker’s extenuata, but 
it is probable that the description would not have helped much in recognising 
the species. 
The species may be tabulated as follows : 
la. Fore wing with ground colour dark grey ; hind wing yellowish bicolor p. 180 
b. Fore wing with ground colour light grey; hind wing light fuscous 
peringueyi p. 182 
c. Fore wing with ground colour light or dark yellow .... 2 
2 a. Fore wing with antemedial and postmedial series of orange dots . . 3 
b. Fore wing without such dots ........ 4 
3 a. Fore wing bright yellow; antemediaLspots 4; postmedial spots 7 
croceipuncta p. 178 
b. Fore wing pale yellow, antemedial spots 3, postmedial spots 7 
basipuncta p. 178 
c. Fore wing yellowish white; antemedial spots 3; postmedial spots 7 
albida p. 178 
4 a. Hind wing white . ......... 5 
b. Hind wing not white .......... 8 
5 a. Fore wing densely irrorated with black and fuscous, especially along 
costa, medial fold and inner marginal area . . . mixta p. 182 
b. Fore wing with no fuscous or black irroration along costa or inner 
margin ............ 6 
1 There is a tendency in the areole to disappear, either through anastomosis 
of vein 7 and stalk of 8, 9 or of vein 10 with stalk 8, 9; this coalescence is found in 
the same species with normal specimens and generally veins 6-10 seem to be in a 
state of flux in this genus. There are even more varieties than those given in the 
figures and these are mentioned with each species where they occur.
