230 OLXGIA. By Dr. M. Draudt. 
P. perparvula Schs. (32 k) is a very small, golden yellow species strewn with red-brown, in the median 
area before and between the maculae and in the marginal area tinted brown with indistinctly double transverse 
lines and vein-dots, the small maculae being surrounded with black; the brown undulate line is faded. Hindwing 
of a pure white, in the $ towards the margin brownish. Brazil, Paraguay. 
P. pyrostigma Hmps. (33 g) is on its yellowish ground irrorated with dark brown so that the yellow 
ground-colour only appears in some places, with blackish transverse lines which are bordered with yellow on 
the averted sides, and a double row of vein-dots behind the distal line; the small round ring-macula is yellow, 
centred red, the reniform macula is a small yellow spot, surrounded with red and with 4 yellow dots around 
it and a small white spot below it; undulate line faded brown. Hindwing light brown, on the veins and margin 
darker. Argentina. 
P. pyromphalus Dyar (32 k). Forewing orange-brownish, particularly towards the costal margin darkened 
with copper-reddish grey, with double transverse lines broken up into copper-red vein-dots; the small round 
ring-macula is orange, encircled and centred with brown, the reniform macula is narrow, orange, below with a 
white dot which is continued in a fine line; undulate line blackish, spotted. Hindwing greyish-brown. Mexico. 
P. octophora Hmps. (32 k). Forewing blackish-brown, at the costal margin mixed with red and ochreous, 
the proximal and marginal areas irrorated with reddish, with black rather indistinct transverse lines, with 
small white spots at the costal margin, the maculae being spotted white, yellow and red, the reniform macula 
shaped like an 8; the indistinct dark undulate line begins with a white costal-marginal streak. Hindwing greyish- 
brown. Peru. 
P. aeruginosa Schs. is a very small species; forewing yellowish, strewn with red, in the median area 
grey, at the costal margin lilac-grey, at the base and before the apex spotted yellow, also at the cell-end, and 
here there is below a short oblique white streak; transverse lines reddish, behind them the grey veins are strewn 
with yellow and red. Hindwing white, at the distal margin darkened with brownish-grey. Costa Rica. 
P. leucopis Hmps. (32 k). Forewing yellow mixed with fiery red, from the anterior transverse line 
except the costal margin and anal angle irrorated with reel-brown, with blackish-brown transverse lines being 
spotted yellow on the averted sides, and with yellow, red-centred maculae, the 8-shaped reniform macula below 
spotted white; undulate line dark, faded. Hindwing red-brown, towards the base yellowish. Brazil. 
P. pyrosticta Drc. (33 g) is much larger than the preceding, darker reel-brown, at the base, costal 
margin and postmedianly irrorated with orange; the reniform macula is below not white-spotted, but it has 
below in the bordering single fine white dots, and the undulate line is spotted yellow at the costal margin. 
Hindwing dark brown with light fringes. Peru. 
P. naolina Schs. (32 k). The brown forewing is fiery red mixed with yellow, postmedianly and in 
the hindmarginal half of the median area irrorated with blackish-brown, with rather indistinct dentate transverse 
lines, and white maculae being centred yellow and red, the ring-macula triangular, the reniform macula strangu¬ 
lated and in its bordering dotted silvery white; undulate line spotted red and yellow. Hindwing brown. Brazil. 
P. ignitincta Mssn. (33 g). Ground-colour similar to naolina , the yellow and red centred maculae 
are in silvery white rings, and at the apex of the coniform macula there is a silvery white spot outside bordered 
with black; undulate line dark and only at the costal margin marked somewhat with yellow. Hindwing light 
yellowish-brown. Ecuador; Peru. 
P. pyrocausta Hmps. Forewing fiery red mixed with yellow, at the margin irrorated with greyish- 
brown; the anterior transverse line is double, filled up with yellow, the posterior line blackish, bordered with 
grey; the ring-macula is a yellow crescentiform spot, above with a yellow and black dot, the reniform macula 
yellow, centred fiery red, in a yellow ring and surrounded by brown; the red undulate line is distally irrorated 
with yellow. Hindwing whitish, irrorated with brown. Colombia (Rio Cauca). 
15. Genus: Oligia Hbn. 
Extraordinarily similar to Trachea from which it chiefly differs in the loose, not parted tufts on the 
thorax. The abdominal tufts are less developed and only extend to the third ring. Chiefly distributed in the 
North American faunal region, containing numbers of species of mostly small sizes. As to the palearctic species 
cf. Vol. Ill, p. 172. 
0. violacea Grt. (33 g) is a larger, quite pale yellowish-red species irrorated with brown, the basal 
and marginal areas being more yellowish white. The reddish, indistinct transverse lines are finely crenulate, 
the olive-yellowish upper maculae somewhat darker, the coniform macula surrounded with orange. Behind 
the whitish undulate line there are in the centre and at the anal angle blackish spots. Hindwing of a pure white. 
Colorado, California, Sierra Nevada. A very variable species. — The form bridghami G. <£■ B. (33 i) is very 
similar, somewhat smaller, with darker, brownish hindwings, in the median area of the forevving more brownish 
slightly irrorated with bluish-white, in the basal and marginal areas bluish-white, the maculae smaller and 
not yellowish but white. Eastern United States. — egens Wkr. (33 g) is likewise similar but still much darker, 
on its olive-brownish ground irrorated with purple reddish, in the basal and postmedian areas whitish with 
small whitish maculae centred and surrounded with olive. The marginal area is olive-brown with black vein-
