T. mathina Bruce (18 f) is distinguished by entirely orange-yellow antennae; the body is black, mathina. 
with orange spots on the head and thorax; the black abdomen exhibits yellow bands above only on the 3 first 
segments; underneath, the 2nd segment is white, the third shows sublateral white spots. The wings are transparent 
orange-yellow with narrow black distal margins, on the hindwings the lower end of the discocellular is connected 
with the marginal band by a small black spot. The forehips are white in the (J. French Guiana. 
T. aurifera Btlr. (= melas var. Whr.) (18 f) is a large, imposing animal with a black body; head and aurifera. 
thorax with orange-yellow spots, palpi and legs quite orange, the latter except the black tarsi. The forehips 
in the white. The first 4 abdominal rings exhibit orange-yellow transverse bands, the 2 following ones yellow 
dorsal spots and subdorsal blue spots; the second ventral segment is quite white, the 3rd exhibits 2 white spots. 
The yellowish hyaline wings are orange at the costal and proximal margins, the appendage to the proximal 
margin of the hindwing is orange and black-haired. The antennae are quite black. Venezuela; French Guiana; 
Amazon (Para). 
T. fasciata Rothsch. (18 f) is somewhat smaller than the preceding and distinguished by the quite fasciata. 
orange-yellow, black-curled abdomen; only the two last rings are black with white, large, round spots of a blue 
iridescence. All the rest is like in aurilera, also the antennae are black. Peru, Chanchamayo. 
T. frigida Burm. is black on the head and thorax, with white hair; base of antennae yellowish. The first frigida. 
3 abdominal rings black, the others yellow-haired; above there are triangular white spots, which are bordered 
with black on the yellow segments. Venter white. Wings hyaline with black veins and margins being strewn 
with white scales like the hyaline parts, the most densely at the base and proximal margin. Expanse of wings: 
30 mm. Argentina (Buenos Ayres). 
64a. Genus: Corematura Btlr. 
Like the preceding genus, but the antennae are not thickened; the abdomen is strangulated at the 
2nd and 3rd segments and exhibits a very long anal hair-tuft. On the forewings both the lower radial veins 
rise from the cell-angle, in Trichura the middle one rises separated from the lower one above it. 
C. aliaria Druce (18 f) has a considerably more strangulated abdomen than the following. Head and aliaria. 
collar are orange-brown, the rest of the body is greenish bluish-black. The anterior side of the palpi, the sides 
of the forehead, and the hips are white; the 2 first abdominal segments are white beneath, the 3rd exhibits 
a white spot, being forked towards the anal end. French Guiana to Brazil. 
C. chrysogastra Petty (= postflava Guer., abdominalis Wkr.) (18 g) is an easily recognizable species: chryso- 
the head is black, with yellow spots and stripes on the thorax; the abdomen shows yellow, triangular dorsal 9 as1 
spots, broad, carmine lateral stripes, and an orange-yellow venter; the long anal tuft is black. Ecuador, Peru, 
Bolivia, Amazon. 
64. Genus: Pezaptera Btl. 
From the preceding genus it differs by the upper median vein and the two lower radial veins rising 
jointly from one place. The strangulation on the abdomen is only trifling, and instead of the long anal tuft 
there are only short hair-tufts at the end and sides of the last ring. 
P. sordida Wkr. (= divisa Wkr.) (18 g). Blackish-brown, antennal tips white. The abdomen exhibits sordida. 
on the 2 first rings lateral white spots and a ventral spot on the first ring; the anal tufts are carmine. Wings 
hyaline, with black veins, margins, discoidal and apical spots. Expanse of wings: 24 mm. Amazon. 
65. Genus: H omoiseuronia Dyar. 
Siphon well developed; the erect palpi extend beyond the vertex. Antennae doubly combed in the 
3, the shaft thickened in the middle. Abdomen strangulated at the base. Spurs of tibiae short. On the forewings 
the upper median vein rises far from the lower cell-angle; the lowest radial vein is absent. On the hindwings 
both the median veins rise from the same place and approach each other again towards the margin; both the 
lower radial veins come from the lower cell-angle, the subcostal and the upper radial vein from the upper one. 
H. modesta Schaus. Body and legs are blackish-blue, the antennae black. Chest, forehips, and the modesfa. 
strangulated abdominal ring, laterally and beneath, are white. Wings hyaline with black veins and margins; 
the hindwings are opalescent whitish, margin and apex are broader black. Expanse of wings: 27 mm. French 
Guiana.
