Gortyna cernssata, nov. sp. (Plate 9, fig. 1.) 
Anterior wings entire purplish brown, sparsely sprinkled with whit¬ 
ish scales; median space large, uniformly tinged with reddish; terminal 
and subterminal spaces showing a silky purple shade. There is a white 
basal spot, beyond which, and separated by the median vein, are two 
slightly yellowish spots, the lower the largest, which precede the basal 
half-line, the latter wavy and tinged with yellowish. Beyond and 
immediately following this line is a very small yellowish spot on the 
median vein. Transverse anterior line nearly straight, darker shaded, 
indistinct, undulating, preceded by a faint yellowish costal mark. 
The three superposed spots, which in this genus usually take the 
place of the orbicular and claviform, are white, obliquely inclined and 
contiguous to the transverse anterior line. The upper spot is pure 
white, very greatly larger than the inferior ones, broadest at its base 
and excavated along its exterior border; the middle spot is soiled by 
the transverse anterior line. Transverse posterior line geminate, darker 
shaded, regularly dentate between the veins, projected superiority. 
Beniform spot preceded by a distinct yellowish costal mark, slightly 
oblique and consisting of a yellow bent central streak surmounted by 
three ^ small nearly confluent linear spots, the largest perpendicular 
and the two smaller ones horizontal giving the appearance of a single 
bi-toothed spot; this central streak is bordered exteriority by three 
nearly equal sized white spots, the upper one bean shaped, the lower 
nearly spherical, opposed to a single one on the side towards the base 
of the wing. Subterminal line undulating, distinct, becoming inter¬ 
rupted towards the internal angle, reddish brown and surmounted by 
a yellowish ill-defined sub-apical spot; fringes long. Posterior wings 
brownish, darker shaded along the veins and external margin, light¬ 
er towards the base. Under surface of both pair brownish; pos¬ 
terior wings lighter shaded, both pair with a darker median shade 
band. Thorax and tegul* purplish brown, latter narrowly bordered
