A. longicornis H.-Schdff. (= venosa Wkr., emendatus Edw., schausi Rothsch.) (55 d). Antennae very longicornis.

a dull dorsal stripe, the terminal half with black dorsal dots. Head orange. Hindwings whitish. Mexico to 
South Brazil, not rare. 
A. phaeophlebia Hmps. (55 d) from Venezuela, is much larger, with broad, hyaline wings tinted pharophlc-

A. inconspicua Schs. (55 d) from Costa Rica has a sooty black body and wings, only the upperhead inconspi-

A. semivitrea Rothsch. ( = pellucida Hmps. nec Sepp) (55 e). Forewings more pointed than in the semivitrea. 
preceding species; head and thorax creamy-white, tinged with yellow, patagia with a fine black median stripe. 
Abdomen orange with a series of dorsal dots; in the forewing there is a blackish dot on the transverse vein and 
a dark comma-shaped spot before the rise of the lower median vein. Panama to Surinam. 
A. nigrostriata Rothsch. (55 e) is easily recognized by the black lines marking the upper cell-wall and nigrostriata.

streak is distinct; abdomen yolk-coloured, at the base whitish. South Brazil. 
A. ruficauda Rothsch. (55 f) is rather similar to longicornis, but the abdomen above purple-red, there- rviicauda. 
fore not to be mistaken for another species. Minas Geraes. 
70. Genus : JBituryx Wkr. 
On the whole very much like the preceding genus, chiefly distinguished from the Agoraca by the short 
straightly porrect palpi, as well as by the 2nd subcostal vein not branching off from the upper cell-wall, but 
only behind the cell-angle. Only few species are known, not differing from the Agoraea in their habits. 
B. lanceolata Wkr. (55 e) is the largest species; head, thorax and forewings milky-white, hindwings lanceolata. 
dirty white; abdomen scarlet with black dorsal and lateral dots. From Hayti. 
B. diversipes Wkr. ( = rhodogaster Snell.). Beside lanceolata the only Bituryx with a red abdomen, diversipes. 
but smaller than lanceolata, and the forewings not milky-white, but dull diaphanous whitish with brown veins. 
Venezuela. 
B. venosata Wkr. (55 e) is quite similar as diversipes, but the abdominal dorsum yolk-coloured, venosata. 
with a white terminal joint; in the $ the dorsal dots are often absent. Mexico and Central America. 
B. grisea Dgn. (55 e). Forewing and apex of the hindwing tinged brownish; before the border of grisea. 
the forewing a row of black dots; otherwise almost exactly like the preceding. Colombia and Peru. 
B. intacta Wkr. (55 e). Thorax and wings white, but head, collar and abdomen bright orange-yellow, intacta. 
Venezuela and Amazon. 
B. pellucida Sepp. Quite similar to intacta, but much smaller; the thorax between the yellow collar pellucida. 
and the orange abdomen not white, but tinged brown, and the forewings light greyish-brown with a violet 
hue and more distinctly dark veins. Venezuela and Guiana.
