DESCRIPTION OF THE PLATES. 



[The figures of the valves have been drawn to about six diameters each, and the others 

 enlarged proportionally but not to scale.] 



Plate XXVI. 



Fig. 1. Ornithoptera Armaria. — The interior of the right valve with its harpe in situ, magnified 6 times. 



Fig. 2. 0. Armaria. — The harpe, separated and viewed as a transparent object, further magnified. 



Fig. 3. 0. Armaria. — The whole genital apparatus, seen from the right side, the right valve having been 

 removed. 



Fig. 4. Ornithoptera Pronomus. — The disk-like extremity of the right harpe, viewed transparently, mag- 

 nified about 40 diameters. 



Fig. 5. Ornithoptera Richmondia. — The disk of the right harpe, magnified about 40 diaui. 



Fig. 6. Ornithoptera Haliphron. — The interior of the right valve with its harpe. 



Fig. 7. 0. Haliphron. — The ultimate segments of the abdomen, and the contained organs, viewed from 

 the right side: the right valve removed; the left with its harpe, in situ, represented in faint 

 outline. The uncus, scaphium, and penis; the last surmounted by the unknown white 

 substance. 



Fig. 8. Ornithoptera Darsius. — The interior of the right valve, with its harpe. 



Fig. 9. 0. Darsius. — The harpe, viewed in the same aspect, further magnified. 



Fig. 10. 0. Darsius. — The same, viewed sidewise. 



Fig. 11. O. Darsius.— The extremity of the penis viewed nearly in front, and with most of the white 

 matter removed. 



Fig. 12. Ornithoptera Rhadarnanthus. — The scaphium and uncus seen from above. 



Fig. 13. O. Rhadarnanthus. — The interior of the right valve with its harpe. 



Fig. 11. 0. Rhadarnanthus. — The right harpe further magnified. 



Fig. 15. 0. Rhadarnanthus. — Teeth of harpe, viewed laterally, and more highly magnified. 



Fig. 16. 0. Rhadarnanthus. — The scaphium and uncus, together with the penis, seen from the right side. 



Plate XXVII. 



Fig. 1. Ornithoptera Heliacon. — The interior of the right valve, with its harpe. 



Fig. 2. 0. Heliacon. — Disk of same harpe, further magnified. 



Fig. 3. Ornithoptera Heliaconoides. — The interior of right valve, with its harpe. 



Fig. 4. 0. Heliaconoides. — The harpe, further magnified. The outlines around the central figure repre- 

 sent the forms of the teeth opposite to them when these are viewed to advantage. 



Fig. 5. Ornithoptera Brookeana. — The interior of right valve, with its harpe. 



Fig. C>. O. Brookeana. — The marginal teeth of the latter, more highly magnified, and viewed nearly in the 

 plane of the harpe, so as to show them in elevation. 



Fig. 7. 0. Brookeana. — The scaphium, viewed vertically from above. 



Fig. 8. O. Brookeana. — The scaphium, seen from the right side. The left valve ami its harpe are indi- 

 cated in faint outline. 



Fig. 9. Ornithoptera Amphrysus. — The interior of the right valve with is harpe, magnified about 7 times. 



Fig. 10. 0. Amphrysus. — The abdominal organs, seen from above. 



Fig. 11. — O. Amphrysus. — The abdominal organs, seen from the sides, both valves having been removed. 



Fig. 12. Ornithoptera Remus. — The right valve and harpe. 



Fig. 13. O. Remus. — The harpe, more magnified. 



Fig. 14. 0. Remus. — The same, in outline, flattened.
