subcostal, ill-defined, darker brown, transverse spot beyond me- 
dian area; marginal cilia as on dorsal surface. Hind wings 
ventrad slightly darker iridescent brown, strongly irrorated 
with heliotrope scales over costal and outer areas and with a 
row of linear, heliotrope dots extending from costa obliquely 
across the cephalic two-thirds of wing to a line from base to 
anal lobe. Of these dots the costal is most prominent and almost 
white. These dots have faint counterparts on the dorsal surface 
but the latter extend farther toward inner margin, which is 
heavily fringed with pale brown cilia; the basal, median, and 
inner areas of the hind wing and the basal area of the fore 
wing on their dorsal surfaces are heavily clothed with long hair 
of a golden brown hue. Tegulse concolorous with wings. 
Ventral surface of thorax and abdomen whitish ochraceous, 
growing darker toward apex of abdomen, so that sixth abdominal 
sternite has a dilfused, longitudinal, brown, median stripe, and 
seventh is nearly all brown, with sublateral suffusions of helio- 
trope. Anal tuft nearly as long as abdomen, very dark iri- 
descent brown, the iridescence more marked ventrad. Fore and 
mid legs with femora and tibise brown ectad, creamy white 
entad; tarsi brown with creamy white at articulations. Hind 
legs uniformly brown, very hirsute, the tibise and tarsi having 
very dark brown hairs, lying in the same plane, lengthening 
toward apex of tibia and growing shorter toward apex of tarsus. 
Total length (including palpi and anal tuft), 48 millimeters; 
width of head, 5.25; length from front of head to apex of ab- 
domen, 30 ; length of anal tuft, 18. Expanse of wings, 60 milli- 
meters ; length of fore wing, 28 ; length of hind wing, 23 ; length 
of antenna, 20; length of hind leg, 23; hind tibiotarsal length, 
17 ; tibial fringe, 4. 
Luzon, Laguna, Los Banos, P. L; July 8, 1915 {Charles S. 
Banks). A single specimen flew into my house at night and, 
rapidly half crawling, half flying, around on the table, was cap- 
tured without injury. 
Type, No. 18468, male, in the entomological collection. College 
of Agriculture, Los Banos, P. I. 
This species is closely related to lontha umbrina Doubleday, ^ 
from which it differs most strikingly in having the anal angle of 
the hind wing lobed and much reflexed ectad; in having the 
heliotrope submarginal band extended to anal angle on hind 
wings and equally as well marked as on the fore wings, and in 
the alternately pale and dark brown fringe of the fore wings.
