74. Genus: I^ophomyra Schs. 
This genus has a very smooth frons and a rather short, feebly developed proboscis; palpus longer than 
in the preceding genus, pro- and metathorax of the scaled thorax exhibit loose tufts, the abdomen being tufted 
on the first rings, the tibiae clad with long hairs and scales. But one species: 
L. tacita Schs. (42 b). Forewing in the basal third of the costal margin lilac, at the base strewn with 
black, in the median area light brown, in the distal half whitish, strewn with yellowish-green, in the centre 
of the cell and below it shaded with lilac, below the cell-end greenish-yellow, bordered with red-brown, the 
end of the median white; transverse lines blackish-brown, the posterior line dentate and on the ends of the 
veins dotted, distally bordered with white, proximally shaded with lilac; the middle radial branch is black- 
striped, above it the undulate line is brownish-grey, below it shaded with yellowish-green, the margin behind 
it whitish. Hindwing lilac brown. Expanse of wings: 31 mm. Costa Rica. 
75. Genus: Acroria Wkr. 
Of the same structure as Xylomyges, but the frons is quite smooth, without a horny plate, and almost 
bare, without any scales. 4 tropical species have been described. 
A. terens Wkr. (= infensa Wkr., villipes Wkr., pulchra Mschlr., niphanda Drc.) (37 h). Forewing 
on the red-brown ground irrorated with dark, with black-striped veins, indistinctly double transverse lines, the 
maculae surrounded with black, with 2 light greenish clots outside at the reniform macula; from the coniform 
macula a black streak extends to the postmedian line, the undulate line is somewhat lighter. Hindwing of 
a pure white with brownish veins. Mexico to Brazil. 
A. denterna On. (37 h) is the largest of 3 very similar species with ochre-yellowish forewings, at the 
hincl-margin being dark brown; the transverse lines are only indicated by double streaks at the costal margin, 
the posterior line besides by vein-dots, in the brown hindmarginal portion it is distally bordered with white; 
the maculae are in lighter rings. In this species the $ forewing beneath is thickly covered with modified brown 
scales. Brazil to Paraguay. 
A. mexicana Hmps. (— denterna Drc.) (37 h) is smaller and neater than the preceding, in the $ without 
the brown scales on the forewing beneath, of a lighter yellowish than denterna , the maculae only indicated 
as small light spots; the white undulate line is only visible in the anal portion and distally bordered with a 
scarcely darker colour. Mexico. 
A. diminuta Gn. (= rotundata Wkr., lignigera Wkr., denterna Drc.) (37 h) is the smallest of the 3 
species, the most distinctly marked, the reniform macula well expressed, quadrangular, the ring-macula entirely 
absent, above it an oblique brown costal-marginal streak; the white undulate line which is visible in the anal 
portion is on both sides intensely bordered with dark brown. Apex and proximal angle are rounder than in 
the preceding. Widely distributed from Mexico to Brazil. 
76. Genus: Acrorlodes Hmps. 
Separated from the preceding genus by the thorax being clad with hair and hair-like scales, the prothorax 
showing a long loose tuft, the mesothorax small double tufts, and the metathorax a large rounded tuft; the 
abdomen exhibits quite a number of tufts, the one situate at the base being particularly large and double. 
Biit one species: 
A. diplolopha Drc. (37 h). Forewing as far as the posterior transverse line deep red-brown with lighter 
veins, in the distal third greyish-yellowish, at the costal margin obliquely to the apex darkened by blackish, 
with very pointedly dentate transverse lines filled up with yellowish, the reniform macula in a yellowish-white 
ring. Hindwing yellowish-white, distally broad blackish-brown. A very variable species: The form diplolophella 
Strd. (= ab. I. Hmps.) has the head, thorax, and the basal half of the forewing ochre-yellowish. - diplolophatia 
Strd. (= ab. 2. Hmps.) has the median on both sides bordered with black and a black connecting streak between 
the transverse lines. — diplolophodes Strd. (= ab. 3. Hmps.). Here the forewing is suffused with black as far 
as the undulate line, only the costal-marginal area remaining yellowish, the hindmarginal area reddish-brown. 
Peru. 
77. Genus: Tliyatfrodes Hbn. 
The frons here exhibits a rounded projection in the centre of which there is a short elliptic horny 
appendage with a raised edge and a horny plate underneath; the last palpal joint is porrect. The thorax is 
clad with hair and scales and midway exhibits a broad comb of erect scales. The abdomen is roughly haired 
at the base, but tuftless. But one species:
