EXOTIC WICROLEPIDOPTERA. 
dorsum beyond middle ; two blackish dots transversely placed on 
end of cell; a faint light greyish shade from middle of costa to disc 
before these, then abruptly angled up and curved round behind 
them, running to a moderate suffused grey spot on dorsum before 
tornus ; a slightly curved cloudy light fuscous line from beneath 
costa towards apex to tornus, and some suffusion near termen above 
middle : cilia whitish, a subbasal series of small fuscous spots. 
Hindwings and cilia white ; 3 and 4 connate, 6 and 7 nearly 
approximated towards base.

Trinidad R., Panama, in U.S. Rat. Mus. 
Antaeotricha frontalis, Zell. 
The structure of vein 8 of hindwings in the male of this species is 
extraordinary, and does not appear to have been noticed by anyone ; 
it is appressed to cell towards base, then curved up towards costa, 
and presently receives towards its apex what appears to be an 
additional vein rising from cell at about §, but must really be 
a long very oblique bar formed by extension of an original 
anastomosis at a point; this structure is similar in the four males 
which I have examined ; I have not seen a female, in which the 
structure may probably be normal. 
Antaeotricha thalamobathra, n. sp. 
. 30 mm. Head, thorax rather light brown, face whitish- 
ochreous. Palpi brown, terminal joint whitish except towards base. 
Antennal ciliations 2|. Forewings elongate, costa moderately 
arched, apex obtuse, termen rounded, somewhat oblique; 2-5 
approximated, 7 to apex (indefinite); rather light brown ; a blackish- 
brown bar from base of costa reaching half across wing, two other 
short bars beneath costa beyond it (space between these tinged 
whitish), a fourth short bar in disc near beyond and longitudinally 
connected with third, a fifth bar only indicated in disc beyond 
fourth, a short dash beneath fourth ; an extremely oblique suffused 
blackish-brown streak from about ^ to |, dorsal edge suffused blackish 
above from about middle to near tornus ; a rather curved fuscous 
macular subterminal line obscurely indicated on lower |-; an 
interrupted dark brown terminal line: cilia light brown. Hind¬ 
wings pale greyish-ochreous, slightly greyer on dorsal half; cilia 
ochreous-whitish, basal third yellower ; costal area rather expanded 
on anterior half and fringed with rough brownish-ochreous scales, 
a pale oehreous expansible subcostal hairpencil from base reaching 
to about middle.
