Psyche 
[March 
cell varies from open to long petiolate. The species was unrecognized 
by Wiedemann, whose description (1828) differs in notable respects 
from that of Fabricius, suggesting that he did not see the present 
type. Subsequent students have done no better with the brief and 
characterless description. 
Tcibanus quadripunctatus Fab. 1805, Syst. Antliat. p. 99. Amer- 
ica meridionali Dom. Smidt. Mus. Dom. de Sehestedt. The type 
(C.) bears an old handwritten label “T. 4 punctatus ex Am: Mer: 
Schmidt” and is on an old short pin. Palpi, proboscis and outer half 
of left wing missing, but otherwise the specimen in fair condition. 
I have nothing to add to Philip’s (i960) comments on it. 
T ah anus trivittatus Fab. 1805, Syst. Antliat., p. 104, America 
meridionali Dom. Smidt. Mus. Dom. de Sehestedt. The type (C.) 
is labelled “T. 3 vittatus ex Am: Mer: Schmidt.” and bears a red 
lectotype label of Philip’s, who discussed the types (1954). The other 
specimen labelled type (C.) is det. Philip as dorsiger Wied. It lacks 
the shiny subcallus, but through oversight I did not compare it with 
the dorsiger type in Copenhagen. A final specimen (K) is fragmen- 
tary, lacking head and much of abdomen. What remains agrees with 
the lectotype. The lectotype has orange antennae, the style slightly 
darker. All femora black. Fore tibiae two-thirds, the others nearly 
entirely, white. Palpi yellowish, almost wholly black-haired. Frontal 
callus rugose. Wings very lightly tinted. The rather denuded 
abdomen shows an even middorsal stripe. I give here a drawing of 
the type (Fig. 3), which matches closely in proportions of frons and 
antennae my homotype of T. callosus Macq., though slightly larger. 
Specimens from Surinam are an even closer match to this figure, 
though I did not have them available in Copenhagen, unfortunately.
