Resides, the A of Castrica has an oval scent-pad on each wing; on the forewing in the submedian space, 
where it forms the centre of a reflecting spot, on the hindwing before the upper cell-angle. 
phalanwi- C. phalaenoides Drury { — oweni Schs.) (53 b). Forewing light olive-grey, in the cell, in the disc, 
,lcs ' below the apex and along the border yellowish diaphanous spots; the ground-colour towards the proximal 
margin more yellow. Hindwings pale yellow, abdomen orange. From Honduras through Central and South 
America to Rolivia. It varies rather much, though not geographically. 
sordidior. C. sordidior Rothsch. (53 c) is darker than most of the noides, towards the proximal margin not distinctly 
more yellow, the hindwings dingy white, the abdominal dorsum dark grey. Described from Trinidad and the 
Amazon (Fonte Boa); the figured specimen from Villavicencio in Colombia (from where, however, there are 
also phalaenoides). 
51. Genus: Tliyrarctisi Hmps. 
This genus ( Parathyris Hbn.) was established for the singular cedo-nulli, but so narrowly delimited 
that new genera had to be founded already for its nearest allies. I comprise therein 3 well-known species, all 
of which are sepia-brown, with hyaline spots partly covered with fine dots, on the forewing, and a rather sharp 
angle at the border, where the middle radial terminates. In the A the collar is somewhat erect, the tibiae of 
all legs are long-haired, the last tarsal joint of the forelegs with a small curl of hair; proboscis small and not 
capable of action. 
ccdo-nulli. Til. cedo-nulli Stoll (53 c). A large and conspicuous butterfly. The hyaline apical area is obliquely 
cut off from the disc; a large hyaline spot in the cell and one at the middle of the border, divided into two parts 
by a submarginal chain of brown spots. Abdominal dorsum in the $ banded orange; venter chalky-white. 
The butterfly is very widely distributed, but it is of rare occurrence everywhere and, to my knowledge, it was 
hitherto only taken at the light. The largest imagines occur in Rolivia, where it attains a size of close to 70 mm. 
We figure a Rolivian $ from the Rio Songo. From Guiana through Rrazil as far as Rio cle Janeiro, Rolivia 
and Peru. 
semivUrea. Til. semivitrea Joicey (53 c). In this species the hyaline spots are fused to such an extent that the 
whole apical half of the forewing is hyaline, only below the apex there is an antemarginal brown, distally 
pointed spot. Abdominal dorsum in the middle yellow. Peru, on the Upper Amazon. 
friga. Th. friga Drc. (53 c). Apical hyaline spot similar as in cedo-nulli , the hyaline spot in the cell quite 
small, the distal vitreous spot large, intensely dotted. This species has been separated as the genus Gonotrephes 
Hmps. Rolivia (Rio Songo). Peru and the Amazon District, more common than the preceding species, but 
much smaller. 
52. Genus: Zaevius Dyar. 
The species on which this genus is based is unknown to me in nature. Proboscis small; palpi bent up 
as far as the middle of the forehead, antennae doubly combed with short branches; abdomen in the A with 
a large anal tuft. Forewing at the apex somewhat sickle-shapecl, the border below it excised, projecting 
again on the middle radial. The uppermost radial on a common pedicle with the 2nd to 5th subcostal vein. 
The only species known comes from Guiana. 
calocore. Z. calocore Dyar. Size and approximate shape of Thyrarctia friga (53 c). Head and body orange, 
tinted red-brown. Forewings yellow, suffused with red-brown. Middle of costa white, before the apical part 
a small white transverse spot and a dot below it. On the anal marginal half there is a laciniform, semi-transparent 
spot, the apex of which extends as far as behind the cell-end. The latter is surrounded by a flesh-colour; hind¬ 
wings white diaphanous, abdomen pink. From Hoorie in Rritish Guiana. Only the type seems to be known, 
in the National Museum at Washington. 
53. Genus: idpiiiiolis Dyar. 
Roberto Mueller, in 1913, discovered a butterfly from Misantla in Mexico, strikingly resembling 
Zatrephes flavonotata (53 b), but differing in the venation by no vein on the hindwing proceeding from the upper 
cell-wall towards the costal margin; only very shortly before terminating into the border the subcostal bifurcates. 
Thereby, as well as by the longer palpi rising in front of the forehead, the genus differs from the otherwise similar 
Zaevius. 
zutrephica. E. zatrephica Dyar. Almost exactly like Zatr. flavonotata (53 b), from which it is exteriorly easily 
distinguishable by the yellow costal spot at the base of the forewing not forming one large semicircle, but 2 
smaller ones following one upon the other. Mexico.
