" Differs from Richmondia 3 showing 



on upper surface of anterior wing more distinctly the inner 

 marginal green border, and on the under surface a much 

 smaller green discoidal marking ; by the ? possessing the 

 tear-shaped marking more occupied by the dark brown 

 spots within them, by the more general sombre appear- 

 ance, and by the green stripe on the thorax." 



I herewith devote a plate each to the 3 and 2 of this 

 species. In the pi. of 3 3 , fig. 3 represents a variety 

 singularly resembling a specimen of 0. Richmondia in the 

 shape of the subcostal band, and in the appearance of 

 both surfaces of the hind wings, even to the presence of 

 the golden yellow spots, in each 3 in number on the upper 

 portions ; fig. 7 represents the subcostal band of the 

 specimen of Richmondia, referred to, which is in the col- 

 lection of Dr. F. Walker. The greens of this Cassandra 

 are all very warm olive, or golden emerald, brightest on 

 the Secondaries. The latter are a rich blue green against 

 the light. The under surfaces are a light green lemon and 

 golden yellow. The black of the upper surface is jet 

 black ; of under surface very dark brown ; a silky greenish 

 obliquely, and opposite the light. Thorax equally black, 

 with a golden green central longitudinal stripe or ray. 

 The fringe of the abdominal fold dark umber ; a green 

 undulated band on the posterior margin extends to the 

 subcostal band ; and is broad. Secondaries with 4 rather 

 small black spots with golden spots between 3 of them 

 and the marginal black border, and an extra one inside 

 the costal nervure. The corresponding golden spot on 

 under surface, fills up nearly the whole of the space from 

 the base to the first large black oval oblong spot. (Con- 

 sequently differing from that in fig. 6 which is very small, 

 and from fig. 2 where the whole space nearly is filled with 

 black, containing a small golden green spot, longitudinal, 

 pyriform, from the precostal nervure, followed by green 

 atoms sprinkled over the black.) Sides of thorax with 

 less red than in other specimens. The Prismatic relation- 

 ship is with P. Ctcbsus. The length of the costa 74 mm., 

 of abdomen and antennae 28 mm. 



3 . The sexual patch of Primary wing in this specimen 

 is of a warm brown velvet. The costal green band is of 

 the normal Priamus form, and the green irregular band 

 extends from the base of the inner, to 2-3rds of posterior, 

 margins ; the subcostal to the discocellular nervures are 

 broadly black. Of the black spots on Secondaries only 3 are 

 visible, the 2nd and 3rd being smallest. Under surfaces 

 very dark brown. A very small irregular-shaped spot in 

 the cell of Primary wing, green blue ; green spots and 

 markings ranging from blue green to golden green. The 

 hind wing has a very greenish golden inner border 

 with still more golden centres between the nervules. One 

 small gold spot in green of costal and subcostal nervures, 

 as mentioned above. Eyes dark brown. Red of thorax 

 not extending down by the legs as in some species. Eyes 

 margined with white beneath. Articulations of antennae 48. 

 Prismatic reflections of Crasus and Urvilliana. 



Length of costa 78, width of upper wing 45 mm. : of 

 hind wing, length 48, width 48 mm. ; of antennae 32 ; 

 thorax and head 11 ; width of thorax 1 1 ; of abdomen 10 ; 

 and length of thoracic stripe 8 mm. 



3 . Secondaries with 4 large sub-oval spots of black, 

 the lowest cuneiform or wedge-shaped. Space above and 

 below the costal nervure black ; the nervures black, with 

 black atoms much sprinked on each side, and on green 

 from the base of the wing. On under surfaces of wing, all 

 the black spots are very large, and unite with the black 

 bordering the nervures and nervules, which at the former 

 is very broad. The green irregular-shaped spot of dis- 

 coidal cell in upper wings slightly larger than in fig. 6 ; 

 and the longitudinal small stripe or mark generally found 

 between the 4th and 5th subcostal nervules is quite absent. 

 Length of the costa 75 mm. (See figs. 1, 2.) The green 

 patch in discoidal cell of fig. 4 will be seen to be much 

 larger than in any other, and almost rectangular : while 

 a few green atoms are sprinked at the base of the cell. 

 All the examples figured in this plate are from the collec- 

 tion of Mr. Oliver Janson ; but the real localities I am 

 unable to give at present. The figs. la, 3«, and 5a, 

 represent the varying form of the 3 sericeous patch. 



The figures given below exactly represent a 

 variety in the author's museum, viz., 7 3, lower surface 

 of secondary ; ja, upper surface of same wing ; jb, upper 

 surface of Primary wing ; and yc, form of sericeous patch.

Figs. 8, and 8a, also represent slightly modified forms of 

 costal band and 3 ser. patch of another example in the 

 same collection. 



3 . Secondaries with 4 black spots on upper side, the 

 1 st large and confluent with the black of the costa. 

 Abdomen orange yellow, with lateral cloudy spots, besides 

 subdorsal dots. Resembles a large Richmondia. The 

 green marginal band of the Primary wings of this and 

 another example from the same locality much indented 

 or scalloped ; in the latter the hind-wing spots are 5, the 

 5th, or costal being covered by the upper wing. Hab.
