half widens very rapidly toward the bases of the antennae. 
Ocellar triangle very long and narrow, the anterior ocellus 
being placed close to the upper third of the distance sepa- 
rating the occiput from the antennae; the ocellar triangle 
is faintly depressed in the middle, but not saddle-like. An- 
tennae (Fig. 1C) small, crowded together; first segment 
about twice as long as the second, slightly swollen through- 
out; second segment rather large; third segment flattened 
pear-shaped, distinctly longer and broader than the sec- 
ond, gradually narrowed apically. Style longer than the 
antenna, the two basal segments of very unequal length 
(the first the shorter). Legs rather slender, of normal 
shape. 
Wing (Fig. 1A) long and comparatively narrow, less 
than four times as long as wide, rather uniformly yellow- 
ish-gray; veins yellowish-brown. Costa distinctly devel- 
oped along the hind margin and reached by the diagonal 
vein. Alula broad. Venation normal, the same in both 
wings. 
Length: 16 mm.; length of wing: 18 mm.; width of 
wing: 4.8 mm. 
Holotype male, Doi Sutep, a mountain near Chieng Mai, 
northern Siam, February 9, 1928 (T. D. A. Cockerell Col- 
lector. — M. C. Z., Cambridge, Mass.). The locality has 
an interesting flora, partly resembling that of the Hima- 
layas (see T. D. A. Cockerell, 1929, Torreya, XXIX, pp. 
159-162).
