of forewing diffuse, nearly straight, of hindwing much less irregular than 
in lataria, only with a weak bend in cell in order to pass proximally to 
the cell-spot ; postmedian of forewing with only a gentle subcostal curve, 
of hindwing almost straight. Under surface coloured as in lataria , but 
showing corresponding differences in the course of the lines ; median 
shade on both wings thick ; subapical white spot on both wings reduced 
in size. 
hiatal (Clark), without more exact data. 
Aids incauta, n. sp. (PI. XXV, Fig. 35). 
A, 30 mm. Face fuscous, darkest in upper part. Vertex and antennal 
shaft whitish, the latter feebly darker-banded ; pectinations very long, 
terminating in stiff, bristly, forward-directed single hairs which are much 
longer than the rest of the ciliation ; apex of antenna simple (extreme 
tip lost). Thorax and abdomen above whitish, coarsely irrorated with 
fuscous and with large paired fuscous spots ; tegula also with some rather 
large dark spots. Legs mostly fuscous, paler beneath and at ends of 
joints and with hindleg (especially the tarsus) paler than the others ; hind- 
tibia not dilated. Shape, colour, and facies of the South American genus 
(or subgenus of Boarmia) Stenalddia Warr., ochreous whitish irrorated 
with fuscous, about as in S. mollearia Walk., List Lep. Ins., XX, 357, etc. 
Forewing with fovea well developed, SC 1 " 2 on a common stalk nearly 2 mm. 
m length, E 1 rather curved at its origin, arising much nearer to E 2 than 
to SC 3 - 5 ; lines fuscous, spotted with black on the veins ; antemedian 
from 30sta at two-sevenths to- posterior margin near the base, curved m 
cell, then oblique, weak at the folds ; proximally to it faint traces of 
another line, which would probably meet it at posterior margin as in many 
Stenalddia , etc. ; median line weak, not thickened except at the veins, 
about parallel with antemedian at 2 mm. distance ; an ill-defined discal 
dot touching this line ; postmedian from two-thirds costa, slender (the' 
spots on the veins small, but distinct), very slightly incurved costally, 
bluntly angled outwards at E 2 and very slightly at SM 2 , forming a long 
but scarcely appreciable inward curve between, reaching posterior margin 
at almost two-thirds ; subterminal lunulate-dentate, not very slender, 
rather indistinct and somewhat interrupted, the lunules weakly dark-filled 
proximally ; terminal area also with weak, ill-defined dark clouding in 
places, chiefly between postmedian and subterminal lines from E 2 to M 1 
and between subterminal and termen from E 2 to apex in the form of thick 
interneural streaks ; termen with conspicuous dark intern eural spots ; 
fringe with weaker and smaller spots at vein-ends. Hindwing with the 
median line becoming antemedian, angled on E 3 ; a conspicuous oval 
cell-spot ; postmedian rather near cell-spot, being over 3 mm. from 
termen, anteriorly curved parallel therewith, posteriorly a little incurved, 
bending outwards again from fold to inner margin ; distal area and fringe 
as on forewing. Under surface with the dark lines distinct, simdarly 
formed, only the antemedian rather obscured by some dark basal shading 
of f ©rewing ; on both wings somewhat enlarged costal spots at origin of 
lines ; discal spot on both wings large ; distal area almost without dark 
shading, sub terminal therefore invisible.
