DESCRIPTION OF THE SPECIES. 



1. T. eximia Wied. £ 9 • — Lutea, abdomine nigro-fasciato ; scutellum 

 magnum, planum, setis sex validis iustructum ; alarum pictura fusca 

 inde a basi maculis irregularibus variegata ad ultimum usque trientem 

 pertinet, ubi vittam costalem et fasciam a margine antico ad posticum 

 oblique ductam emittit ; praaterea in margine antico duae maculae tri- 

 gonae et hyalinae, in postico duae subovatae et subhyalinae conspiciuntur, 

 ad quas in speciminibus plerisque macula rotunda hyalina in cellulae 

 discoidalis basi sita accedit. 



Clay-yellow, abdomen banded with black ; scutellum large, flat, with six 

 strong bristles; the brownish-black coloring of the wings reaches from 

 the irregularly spotted basis to the last third of the wing, where it 

 emits two bands, one of which forms a border along the costa, the other 

 runs obliquely from the anterior to the posterior margin ; moreover, the 

 anterior margin shows two triangular hyaline spots, the posterior margin 

 two almost oval and less hyaline spots; most specimens have, besides, 

 a round hyaline spot on the basis of the discal cell. Long. corp. 

 0.2tJ—0.26, 2 cum terebra, 0.29—0.30; long. al. 0.25—0.26.

CI ay -yellow; head of a somewhat purer yellow, rather disci- 

 form. Front narrow, still more narrowed anteriorly, with a 

 small, but well-defined frontal lunule. Frontal and vertical 

 bristles black, rather long and strong; the upper half of the 

 posterior orbit of the eyes with a row of black and blackish-brown 

 bristles. Antennae clay-yellowish, third joint elongated, rounded 

 at the tip; arista very slender, with a hardly perceptible pubes- 

 cence. Face perpendicular; the edge of the mouth not upturned ; 

 palpi yellowish, broad, reaching as far as the anterior edge of the 

 mouth ; their pubescence, as well as that of the mentum and of 

 the occiput, is yellow. Thorax rather strongly built, compara- 

 tively broad between the roots of the wings ; the humeral callus 

 and a longitudinal stripe between it and the root of the wing, are 

 yellowish-white or sulphur-yellow; a longitudinal stripe of a 

 similar color, which is generally but little visible in dried speci-
