﻿The following table of the $ $ will enable us to readily separate the species of this genus :— 



A. Anterior Wings.

 length, Meridionalis ; about 1 and 3-4ths, Tithonus ; nearly two times, Goliath. 



2. Inner margin of wings straight, Titan, Goliath, Paradisea, Tithonus ; nearly straight, Meridionalis. 



3. Wings larger and wider than the posterior wings, Titan, Paradisea. 

 3a. Much larger, Meridionalis. 



3b. Very little larger, Tithonus. 



3c. Wings larger, but the same width as the posterior wings, Goliath. 



4. The 3rd subcostal nervure emitted close to the apex of the discoidal cell, Titan, Paradisea, Meridionalis. 

 43.. The 3rd subcostal nervure emitted at 3 millimetres below the apex of the cell, Tithonus 



4b. The 3rd subcostal nervure emitted at 2 mms. below the distal end of the cell, Goliath. 

 4c. The 4th and 5th subcostal nervures emitted at 8, 9 or 10 mms above, or beyond the apex of the cell, all 

 4 species. 



B. Posterior Wings, $ . 



1. Wings rounded, Titan. 



ia. Irregular in form or outline, Tithonus. 



ib. With a caudal prolongation of the 3rd median nervure, or tailed, Paradisea, Meridionalis. 

 ibb. The terminal of the tail leaf-like, Meridionalis 



ibbb. Costa nearly straight; the rest of the wing outline somewhat rounded, but terminated almost to a 

 point at the anal angle, Goliath. 



2. Upper surface of wings yellow, green and black, Paradisea, Goliath, Titan, and Meridionalis ; the black of the 

 latter broken up into lines. 



2a. Wings of the 3 colours, with 3 orbicular black discal spots, Tithonus. 

 2aa. With three orbicular green discal spots, black pupilled, Titan. 



2aaa. With 3 orbicular green spots, the lowest with a black pupil, Goliath. 

 2b. Under surface of wings without black orbicles, Paradisea, Meridionalis. 



2bb. With black orbicles, and marks, Titan, Tithonus ; in the former there are only three. 

 2bbb. With 3 black orbicles only, Goliath. 



3. With white abdominal marginal fringe of long hairs, Meridionalis. 

 3a. The fringe creamy white, Paradisea. 



3b. The fringe sienna colour, Tithonus. 



3bb. The fringe very short and light sienna colour, Titan and Goliath. 



C. Head. 



1. Antennae of Titan and Goliath slim like those of Goliath 2 . 



2. Eyes lighter than in the other species of the genus. 

 2a. Eyes darker, Goliath. 



D. Thorax. 



1. Thorax entirely black, Titan, Tithonus, Goliath. 



ia. Not entirely black, but with a longitudinal leaf-like yellow mark, Paradisea. 



ib. With four greenish-yellow marks, Meridionalis. 



E. Abdomen. 



1. Golden yellow, Paradisea, Tithonus, Titan, Goliath. 



ia. Lemon-yellow, Meridionalis. 



2. With a long dark striped longitudinal mark, Paradisea. 

 2a. With a simple grey longitudinal stripe, Meridionalis. 



2aa. With no longitudinal, or only a faintly greenish, stripe, Tithonus. 

 2aaa. With no longitudinal stripe, Titan. 



F. Legs.
