C. zagraea Fldr. (7 c) occurs in Panama. The four specimens of this species before me like their 
figure in Biolog. Central.-Amer. do not show the lighter colour at the margin of the fore wing present in our fi¬ 
gure. 
C. carilla Schaus. Antenna yellow with black base. Thorax dark brown with yellow spots. Abdomen 
reddish with a sublateral black stripe, whitish yellow beneath. Forewing black, basal half of the cell and a 
broad longitudinal band in the dorsal area reddish brown, a spot at the apex of the cell and a streak 
opposite at the costal margin yellow, a postmedian rectangular brown spot traversed by vein 3, a subterminal 
oblique row of yellow spots, a row of yellowish white marginal spots. Hindwing reddish with broad black sub¬ 
costal band, black marginal band deeply dentate on the inner side and a postmeclian black band between 
veins 2 and 4. Expanse 96 mm. Allied to C. zagraea, but the basal brown markings are quite different. — 
Costa Rica. 
C. columbina Bsd., from Colombia, measures 120 mm. in expanse and has the forewing black with two 
red longitudinal bands from the base, the lower one of which ends in two whitish smears, moreover about four 
white spots are present and towards the apex there are two parallel rows of white spots. Hindwing reddish 
yellow with black marginal band, and white row of spots as well as 2 or 3 isolated black spots. 
C. cycna Westw. (7 d, on the plate misprinted as cygna) from Colombia, sometimes occurs in a form 
(type C from Bogota) in which the light spot situated behind the transverse spot at the apex of the cell of 
the forewing merges into the postmedian row of spots, while these spots are confluent, forming a continuous 
band (f. modificata form, nov.) (cf. plate VI, fig. 7 in Preiss, Neue Arten Castnia). 
C. daguana Preiss, from W. Colombia, strongly resembles zagraea, but is smaller (expanse 68 mm.), 
while a yellow longitudinal patch is present also in the cell of the forewing, the submarginal spots of the fore¬ 
wing ai’e smaller, those of the hindwing are not pointed at the distal end. 
C. liahneli Preiss, from Venezuela, is also very like zagraea, but considerably smaller (expanse 61 mm), col¬ 
our paler, position and shape of spots at the hindmargin on the underside of the forewing different, the post¬ 
median light transverse markings of the same wing appear as a continuous band instead of a row of spots, etc. 
C. michaeli Preiss (6 e), from the Upper Amazon, is characterised i. a. by the markings of the proximal 
half of the forewing. 
C. juanita Preiss, from N.-W. Colombia, is one of the largest species of Gazera (length of wing 53, ex¬ 
panse about 105 mm.), the only specimen before me, the type, is defective, and has orange-red hindwing, bear¬ 
ing a deep black marginal band about 14mm. broad and sharply marked on its inner edge, enclosing a few 
small yellow submarginal spots. In the forewing a similar marginal band is present, otherwise the forewing 
is light yellow with two or three black longitudinal bands and two black spots. 
C. garleppi Preiss, from Bolivia, measures 90 mm in expanse and resembles zagraea, the black sublim- 
bal spots of the hindwing are, however, distant from each other and quite isolated, and the black marginal band 
has quite short teeth on its inner side, the sublimbal spots of the forewing are smaller, and the row is broadly 
interrupted in the middle. A postmedian transverse row of spots is only indicated by a small light smear, etc. 
C. salvina Westw. (7 e), from Panama, occupies a rather isolated position in this group by the widely 
extended dee}) black colour of the forewing and the markings consisting of single white spots. 
C. cratina Westw. (7 d), from the Amazon, also differs from the type predominant in this group, i. a. 
in the light veins of the forewing. 
F. Hindwing uniformly black. Forewing black with yellow transverse marking in the centre. 
C. truxilla Westw. (7 b), from Colombia, looks rather strange on account of the almost entire absence 
of the spots otherwise so strongly prominent among Gazera. 
Addenda. 
Species which could not be included in the two preceding divisions of the genus Castnia (cf. p. 7). 
C. hechtiae Dyar (8 a), from Mexico, is gray, forewing with black shadows and a white band running 
from near the base along the median vein to the base of vein 2, then filling out the space between 2 and 3, after¬ 
wards extending obliquely costad close to the cell, ending at vein 7. Hindwing orange red with strongly 
curved black band at the apex of the cell, a submarginal band of black spots and narrow black marginal 
band. expanse 65 mm. — This species, with which I have only lately become acquainted, should form a 
separate group among the true Castnias.
