AZATREPHES; CASTRICA. By Dr. A. Seitz. 
B7D 
Z. nitida Stoll (nec Rothsch.) is extremely similar to the preceding, but 2 dull lines in the middle nitida. 
of the forewing cut each other (like in cruciata) on the submedian vein, and behind the cell-end there is a small 
band of 4 or 5 small diaphanous light spots. The wings above with a slight mother-of-pearl lustre; hindwings 
pink with white fringes. Guiana and Peru. 
Z. ossea Schs. (53 b). Forewing dull whitish with a brown border and 2 thick, oblique, brown transverse ossea. 
lines. In the hindwing the whole proximal area is purple-pink, like the abdomen. French Guiana. 
Z. lentiginosa Rothscli. (53 b). Forewing yolk-coloured, the two transverse streaks distinct only in lentiginosa. 
the inner-marginal area; between the radials a white dot finely excircled dark. Hindwing yellow with a red 
border and white costal area. French Guiana; discovered by Le Moult. 
Z. pseudopremolis Rothsch. (53 b) is quite unlike the genus by approaching species of the same pscudopre- 
range from other genera ( Neonerita arcifera, syrissa, Eupseudosoma affinis, Premolis rhyssa etc.). Adjoining mol-is. 
to the purple-violet basal part a large, diaphanous pale yellow apical part. A purple-brown costal stripe sends 
from the apex a small faint costal band 2 or 3 mm far into the wing. Hindwings and abdomen pale pink. Peru. 
Z. flavonotata Rothsch. (53 b) is somewhat similar, the brownish-violet preapical spot more intense, tlavonotata. 
at the basal part a lemon-coloured semicircular spot is situate on the costa. Amazon. 
49. Genus : Azatrephes Hmps. 
5 species, allied to the preceding, chiefly distinguished by the venation of the hindwing, where the 
upper cell-wall, being unparted and unforked, is continued to the border. They are small butterflies with a 
large, lobated hyaline spot in the disc of the forewing. The centre of their range is like that of the preceding 
genus on the Amazon, presumably also near Fonte Boa; from there they are distributed as far as Guiana 
to the north-east and Peru to the south-west. The species in their habits do not differ from the allied genera 
and are probably without exception taken at the light. 
A. paradisea Btlr. (46 m). Smaller than the smallest Zatrephes, recognizable by the large, hyaline paradisea. 
postcellular spot with a slight silky lustre, on the forewing. Forewing golden yellow with a silvery reflection 
and a red, net-like marking. Proximally to the hyaline spot a brown oblique line runs from in front of the 
middle of the costa to beyond the anal angle to the border. Hindwings tinted pink, the costal part somewhat 
transparent. Abdomen of the A and $ purple-red. Amazon, Peru. 
A. traili Btlr. (46 m). Easily recognizable by the somewhat irregularly shaped, above narrower, greasy- traili. 
lustrous hyaline spot in the distal area of the forewing, extending from the 3 rd costal vein to the submedian 
space; it is bordered with scarlet and somewhat irregularly defined towards the orange-yellow basal part inter¬ 
mixed with red lines and small spots. Hindwings tinted pink; abdomen above hemochrome. From the Amazon. 
A. discalis Wkr. (46 m). The hyaline spot of the forewing is here very large and is defined towards discalis. 
the whitish and also somewhat silvery lustrous apical and basal areas by brown, distally very dull delimi¬ 
tations. Hindwing whitish, towards the border faintly tinted rosy. Abdomen in the £ buff, in the £ silvery white. 
Amazon. Peru. 
A. argyrotis Hmps. (46 m) is almost like discalis, but the non-liyaline part of the forewing almost argyrotis. 
entirely silvery, with very few transverse markings. Peru. 
A. fuliginosa Rothsch. (46 m). The typical form has, except the hyaline spot, almost quite purple- fuliginosa. 
brown forewings, and also the hindwings and abdomen are dark brown. There occur, however, transitions 
to the preceding species as well as quite dark forms, of which already Lord Rothschild figures a number of 
intermediate forms. We propose the following denominations only for the extremest forms entirely deviating 
from the type: ab. transiens nom. nov. (46 m) for the specimens with very light, partly silvery lustrous embed- transiens. 
rnents in the forewings, and ab. infenestrata nom. nov. (46 m) for such with the hyaline spot being covered infenestra- 
with brown. In the latter the hindwings and abdomen are dark-brown, in ab. transiens lustrous yellowish-white, 
faintly powdered with brown. — Amazon: Fonte Boa. 
50. Genus: Castrica Schs. 
This genus was established for a species having been known already for 150 years. It is closely allied 
to the Automolis, but it has a feebly angled border of the forewing, which is exhibited only by those Automolis 
of Avhich it is doubtful whether they belong to the group. It otherwise greatly resembles in the exterior the 
Aut. tybris-group (52 g), differs, however, by the middle and lowest radials (= uppermost median vein) of 
the forewing not rising from the same place, but by a distinct lower discocellular being present in Castrica.
