T» fulvicaudata Lathy is at once distinguishable from the preceding by the orange-yellow tail- 
appendage: furthermore, the anterior side of the palpi, the forehips, the 3 first abdominal rings on the ventral 
side and sublateral spots on the 3rd ring are orange. On the yellow hyaline forewing there is below the median 
an orange-yellow basal spot. Paraguay. 
T. monstrabilis Klages. Body black, with metallic blue or green spots on the forehead, vertex, collar, 
shoulders, shoulder-covers, thorax and legs; anterior side of palpi, spots on the neck and forehips in the $ are 
white. The abdomen shows a bronze-green lustre, the strangulated segment is laterally and underneath white. 
The cf with or without a long tail-appendage. Wings hyaline with a black base, margins, middle and apical 
spots. Expanse of wings: 32 to 38 mm. Venezuela. 
T. grandis Kaye is a very large species with an expanse of wings of 50 mm. Body black; the forehead, 
a dorsal spot on the 1st abdominal ring and minute lateral spots on the others are metallic green; on the 3rd 
and 5th segments sublateral white spots. Forewings ochreous-yellow hyaline with very narrow black margins; 
hindwings white hyaline with a broad black proximal margin and apex. South Brazil (Santos). 
T. nielanosoma Hmps. (18 e) is easily recognizable by the large, black apical spot of the forewing. 
The body is jet-black, above with indistinct deep-blue spots on the forehead, vertex, collar, metathorax and 
base of abdomen; the abdomen exhibits on the strangulated segment sublateral white stripes. Brazil (Sa. 
Catharina). 
T. fumida Kaye is smaller than esmeralda (18 e) and has an entirely black abdomen without green 
spots, only the head and thorax exhibit single metallic green, small spots. The forewings are smoky-brownish 
hyaline, the hindwings bluish hyaline, both with a somewhat broader black margin than in esmeralda. Expanse 
of wings: 34 mm. Trinidad. 
T. esmeralda WJcr. (18 e) differs from cerberus by the hyaline forewings not being yellow and their 
narrower margins. The forewings exhibit an orange-yellow spot at the base. The ventral side exhibits behind 
the white basal spot only a pair of white sublateral spots. Honduras, Guatemala, Venezuela, Brazil (Para, 
Rio de Janeiro). — In Colombia flies a form with entirely white, sublateral macular rows: completa form, 
nov., which is before us from the Rio Dagua (A. H. Fassl). 
T. pusilla Rothsch. Head, collar, chest, and a spot on the blackish-brown thorax are steel-blue. Palpi 
white. Abdomen greenish steel-blue; the strangulated ring shows' lateral white spots; tail-appendage as lang 
as the abdomen. Forewings yellow hyaline, narrowly bordered with black. Hindwings whitish hyaline with 
a black apical spot. Expanse of wings: 26 mm. Peru. 
T. latifascia Wlcr. (18 e) has a black body with a deep metallic blue lustre; the strangulated 2nd 
abdominal segment exhibits on each side a large white spot. In the nomenclatural type, the discoidal spot of 
the forewing is broad. This type flies in Brazil (Para, Rio de Janeiro). — In ismene Moschl. (= ribbei Druce ) 
the discoidal spot is very narrow. This form flies more in Central America, Panama, Colombia, Surinam, but 
it is also stated from Bolivia. 
T. dixanthia Hmps. (18 e) is presumably much rather to be considered a form of latifascia, for the 
only difference is the orange-yellow colour of the lateral spot of the 3rd segment; both vary extremely in 
the width of the black margins and discoidal spots, and among a great number of d'c? of both forms lying before 
me, from the same habitat, the one half has a tail-appendage, the other half not, which, therefore, is presumably 
no distinguishing mark, for other differences are not to be discovered. Likewise from Brazil (Minas Geraes, 
Santop). 
T. coarctata Drury (18 e). Body black with minute, metallic bluish-green spots on the forehead, 
vertex, collar, thorax and abdomen, the 2nd segment of which exhibits a white spot underneath; the 3rd segment 
shows 2 white sublateral spots. Wings faintly yellowish hyaline, with black margins. From Venezuela and 
Brazil (Para, Pernambuco, Rio de Janeiro, Santos). 
T. druryi Hbn. (= coarctata Cr.) ( 1 8 f) has a black body being spotted metallic bluish-green on 
the forehead, collar, shoulder-covers and thorax; the forehips, the ventral side of the 2nd abdominal ring, and 
some spots on the 3rd are white. Above, the abdomen exhibits on the first 3 rings metallic green transverse 
bands, on the following rings similar dorsal and lateral spots. The yellowish hyaline forewings have an orange- 
yellow costal and proximal margin, and a narrow black distal margin. In the the black discoidal spot is broader, 
and the hips are black. Widely distributed from Mexico to British Guiana. 
T. cyanea Schaus (18 e) approximates druryi and differs by its quite black, not bluish-green spotted 
abdomen which is orange on the lateral tubercles at the base, and sublaterally striped white on the 3rd and 
4th segments. Head, collar and legs are spotted metallic blue. Costal and proximal margins of the hyaline 
wings are orange. Rio de Janeiro.
