EXOTIC MTCROLEPIDOPTERA. 
dark grey, anal tuft and projecting scale-rings of three prscapical 
segments ochreous-yellowish. Forewings indigo-blue-green, costa 
posteriorly and termen suffused dark indigo-blue: cilia whitish, 
becoming pale grey towards tornus, basal third dark purplish-grey. 
Hindwings dark indigo-blue-grey; cilia wliitish-grey, towards 
tornus and dorsum pale ochreous-yellowish. 
Bolivia, Songo ; I redescribe the species here, from an example 
received from Staudinger, for accurate comparison with the four 
preceding species of the same group. T. boliviano, Busck is an 
allied species, which I also possess. 
Tinea coracopis Meyr. 
(5 5 • 25-32 mm. Seven examples, all different, appear never¬ 
theless to be all referable to this species, and to indicate large 
variability; head (in type wholly blackish) whitish, or partly 
whitish and partly fuscous ; veins sometimes tending to be marked 
with liues of alternate dark fuscous and whitish dots; first discal 
stigma (in type absent) sometimes present, black, obliquely beyond 
plical, plical stigma sometimes eloagate, or continued as a dark 
fuscous streak to base, or diverted to dorsum near base, sometimes 
a more or less developed dark fuscous streak from disc before 
middle running through second discal stigma to apex. All these 
are from the same region, Colombia, Mt. Tolima, 10,500-12,500 
feet, October. One example is exactly like the type from Peru 
except for the whitish head. T. nigriceps Zell, must be closely 
allied, but apparently distinct and constant, as Zeller had six 
examples. 
Trithamnora prismatica Wals. 
This specific name supersedes erebantha Meyr. The genus Lipo- 
merinx Wals. (1914), however, of which it is the sole exponent, is 
a synonym of Trithamnora Meyr. (1913) ; Lord Walsingham is in 
error in stating that there are no lateral bristles on second joint 
of palpi; they are often denuded, but I have specimens possessing 
as many as three; he has also omitted to notice the subdorsal 
scale-tufts, which are slightly developed but certainly present ; the 
species is therefore a true Trithamnora in all respects. 
Demobrotis deferens, n. sp. 
S . 7 mm. Head white. Palpi dark fuscous, tip white. Thorax 
white speckled dark fuscous. Forewings white, scattered black 
scales tending to form an irregular strigulation ; markings brown 
speckled black; spots on costa at 4 and f; a somewhat oblique 
fasciate streak from middle of costa reaching | across wing, 
posteriorly with a projecting lobe at extremity marked with a black 
spot; black submedian spots at base and ^ ; an elongate spot on 
dorsum before middle, and larger triangular spot beyond middle; 
an oval spot marked with a black sometimes interrupted dash in 
disc at 4; some slight irregular marbling towards apex: cilia
