334 TESSELLARCTIA; OCHRODOTA. By Dr. A. Seitz. 
14. Genus: Tessellarctia. 
Medium-sized butterflies, allied to the preceding, with pale, yellowish grey or brownish wings and 
a bright red or orange-yellow abdomen spotted transversely above. Proboscis well developed; palpi rising, 
but very short, the middle joint being shortened, the terminal joint stunted and almost entirely vanished. 
No accessory cell; the 2nd subcostal vein rises separately from the upper cell-wall, before the cell-end. 3 species 
are known being confined to South Brazil and all rare; a 4th species, from the Upper Amazon, deviates struc¬ 
turally to such an extent that Hampson established a new genus — Pydnaodes —- for it. In this species also 
the abdomen is unicolorously brown, not yellow or red with black transverse bands as in the genuine Tessel- 
larctia. 
T. cinerascens Wkr. (43 b) is rather similar to Hypocrisias jonesi, but the abdomen is above marked 
black, and in the distal area of the forewing the bone-white colour almost entirely displaces the brown ground¬ 
colour. Hindwing except a light costal-marginal spot quite dark brown. South Brazil. 
T. seniivaria Wkr. is smaller and has light, netted brown spots only in the basal part of the forewing 
at the middle of the costa and round the apex; the abdomen is above purple. South Brazil. 
T. ursina Schs. has almost quite brown wings, only at the base, at the costa and cell-end, and before 
the border of the forewing there are small bone-white or reddish-yellow spots; abdomen in the $ above scarlet 
with black transverse spots. South Brazil. 
T. distincta Rothsch. (43 b), the only northern species, from Fonte Boa on the Amazon, shows yellowish 
brick-coloured forewings; above the proximal margin a dark brown, half oval light buff longitudinal spot; 
the distal 3 / 4 of the proximal margin broadly leather-white. Along the border a whitish leather-coloured line. 
A subapical dark brown spot touches an irregular oblique band and connects it almost Avith the spot above 
the proximal margin. This band is on both sides bordered by an interrupted white line. Hindwings dull orange- 
brown, with irregular dirty-brown bands and spots. Abdomen brown. Hampson establishes-a genus of its 
own for this single species: Pydnaodes. 
15. Genus: Oclirodota Hmps. 
Distinguished by the considerably broader wings, by the longer middle palpal joint and the subcostal 
vein of the hindwing rising from the middle of the upper cell-wall. The species, all of Avhich, except one, were 
described only in the last decade, are A r ery much alike. 
0. pronapides Drc. (43 a) is entirely marked like the Tessellarctia, earth-brown clouds on the forewing 
alternating Avitli bone-Avhite, netted broAvn patches. The brown colouring in the middle of the forewing is proxi- 
mally defined by a line extending from the middle of the costa in a slight curve to the submedian fold and 
from there to the base of the Aving. Abdomen yolk-coloured; hindAvings brown, in some places light yellowish. 
From Guiana through the Amazon District to Ecuador. — major Rothsch. is a large 2 from the Volcan de 
Chiriqui. 
0. marina Schs. Forehead light brown, vertex Avhitish, tegulae and patagia white, bordered with 
brown; thorax posteriorly dark brown, abdomen yelloAV Avitli black lateral spots and a black subdorsal spot 
at the end. Forewings dark brown, the darkest along the proximal margin, in the middle before vein 2 and 
behind the cell; base, the median space above the submedian, the cell next to its end and the costal margin 
at the cell-end whitish with reddish-broAvn rings and irregular lines. Apical part above vein 6 also whitish 
with similar lines. Hindwings yellow, border black, narrower at the anal angle as Avell as at the apex. Under 
surface similar, paler. Expanse of Avings: 33 mm. From the Sixola-Rfver. 
0. similis Rothsch. Like pronapides (43 a), but the tegulae are brown like the patagia, the forehead 
not white, but dirty yelloAvish-brown, the pale basal area of the foreAving is brown Avith 12 Avhite spots (not 
whitish, speckled brown), and in the cell and at the costa there are 2 large Avhite spots; the whitish apical spot, 
speckled broAvn, is absent, too; instead of it there is a small Avhitish spot 1 / 4 before the apex at the costa. In 
the $ the Avhite spots are smaller and the hindwings are darker. Upper Amazon. 
0. affinis Rothsch. Likervise allied to pronapides (43 a); Avings and body unicolorously smoky brown; 
the Avhite areas at the base and before the apex only indicated by a Avhite dot near the base and some buff sub- 
apical spots. Size of the preceding. Upper Amazon. 
0. funebris Rothsch. (43 a). Dark sepia-broAvn, the forewings marked darker, the hindwings of 
a deeper black. At the base and before the apex of the forewing a fine white dot. Peru. 
0. brunnescens Rothsch. Dark brown; recognizable by the white base of the hindwing. Forewing 
with a buff basal third in which there are reddish-yellow rings and spots; a buff spot marked reddish near the 
apex. HindAvings whitish yelloAvish-grey. Surinam and Upper Amazon.
