distally white-gray edges to the row of red-brown spots on the under surface of the forewings. — ninos subsp. 
nov. (108 c as semiramis ) was found in the southern part of the island near the Falls of Maros, between 
November and January. Of the ? there exists, beside the form represented by our figure, another larger form, 
which bears a dark clay-yellow, narrow median band on the upperside of both wings. In the ? the under 
surface is gray in the basal half, silvery white with gray shading in the distal half. 
C. regina. Of this species quite a number of local forms are known, all of which inhabit the Papuan 
Region and the northern Moluccas. Especially in the latter islands the forms vary within comparatively small 
distances to such an extent that for instance the ?? of the forms from Eatjan and Obi might easily be regarded 
as distinct species, cfcf resemble more or less the form imperialis (108 b), the width of the blue distal area 
varying according to the locality. This is also the case on the underside, where the longitudinal band shows 
in the style of its distal bordering the influence of the locality. According to the similarity or dissimilarity 
between the sexes, two general types may be distinguished. - paulowna Frahst. is the only monochrome 
form known to me; it inhabits Batjan and Halmaheira. c? is very similar to the figured cf of imperialis , the 
? however closely approaches on the upper surface the ? of semiramis ninos (108 c). In the ? the forewings 
are dark brown in the basal half, with very broad, either violet or brown bands in the outer half. The distal 
border is not sharply defined, but shades into the colour of the proximal area. The under surface is adorned 
with extraordinarily broad, undulate median bands, with the lighter red-brown submarginal band nearly three 
times as broad as is the case in ducalis and princesa. The type which came from Halmaheira is in the 
British Museum. 1 ? from Batjan in coll. Fruhstorfer. —■ princesa Frahst. (108 b as imperialis , und. s.). On 
the upper surface the ochreous area is lighter and extends much farther, the dark violet terminal border is 
considerably narrower, the band upon the forewings of a radiant blue, in the ? more strongly undulate than 
in the Papuan races and accompanied by a rudimentary parallel antemarginal band. From the island of Obi. 
nasica Frahst. The undulate band crossing the distal half of the underside of the lorewings is much lighter 
(nearly silver-gray) than the one found in the proximal half, all the bands are more sharply dentate. From 
Waigeu. regina Fldr. The violet terminal border on both wings is broader than in the forms from New 
Guinea, I he submarginal bands on the forewings more complete and farther extended. Discovered in Aru by 
Wallace; several specimens in the British Museum. — myra Frahst. (108b as imperialis- cf). In both sexes 
the distal half is dark blue-violet with lighter undulate submarginal bands. Under surface: Basal half thinly 
covered with gray scales, with a broad ochreous median band marked with white; the distal half is traversed 
by broad undulate bands of a metallic gray lustre. From Kapaur in south-western New Guinea. — ducalis 
Wall. In both sexes the submarginal bands are, especially on the hindwings, somewhat more conspicuous 
than in the preceding form. On the under surface the ochreous colour of the basal portion spreads still farther 
and is but slightly dusted with gray-blue. The white median band is very narrow, the metallic submarginal 
fasciae are obsolete. From Humboldt Bay, collected by W. Doherty. — sophene Frahst. cf is smaller than 
in the preceding species; the blue-violet submarginal bands upon the forewings are more sharply defined, but 
are obsolete in the hindwings; on the under surface the markings are more reduced, the red-brown bands 
larger, the undulate lines darker grey-violet, the forewings reddish-gray in the basal half. From Milne Bay, 
where it Hies from June until November; also from Mount Hansemann, Friedrich Wilhelmshafen in German 
New Guinea. 2 cfcf in coll. Fruhstorfer. Hauen found in July near Simbang at an altitude of 1000 ft. 
only one c? and one ?, while in February of the preceding year several hundred specimens were taken by 
two English collectors, which proves the periodical appearance of this form. 
C. imperatrix Sm ., of which only one specimen is known discovered by Doherty in the islands of Biak, 
called Schouten Island by the Dutch, in Geeivink Bay, is distinguished from regina by the fact that also the 
basal half of both wings is shining blue. On the underside the forewings are adorned with large black 
spots, distally bordered with a little white; the silvery white median line is very narrow. 
12 Genus: Terinos Bsd. 
The few species belonging to this genus diifer from those of the closely-allied Cynthia and Cirrochroa 
in being adorned with a most magnificent, blue-violet velvety lustre. Their chief characteristics consist in the 
ciliated eyes (which in the Argynnidae appear nearly always naked), in the manner in which the subcostal 
nervules branch off, in the direction of the lower discocellular which closes the cell in the hindwing and finally 
in the enormous sexual spots. In Terinos, the first subcostal is placed before the end of the cell, the second 
at the very end or a short distance beyond, the third and fourth stand close to one another and some little 
distance from the cell. In the cf the lower discocellular joins the median vein at the origin of the second 
nervule, in the ? between the first and second, The costa of the forewing is serrate. In the hindwing the cell 
is remarkably small and is closed by the lower discocellular which is very thin and in both sexes joins the 
median between the first and second branch. Moreover the cfcP have a deep fold beyond the cell, as is found 
in Cynthia and Cirrochroa. Palpi distended as in Cirrochroa. However the main characteristic of the genus 
is the inconstancy of neuration, which not only shows a difference between different species or sexes, but 
varies even among individuals of the same species or sex. As a rule such differences in neuration are 
generic, only rarely occurring among species that are closely related; in the genus Terinos however this
